BedienungsanleitungDigiswitchV2Sehr geehrter Kunde,wir freuen uns, dass Sie sich für den PowerBox DigiSwitch V2 aus unserem Sor-timent entschieden haben. Wir wünschen Ihnen mit der PowerBox DigiSwitch V2 viel Freude und Erfolg!PRODUKTBESCHREIBUNGDer PowerBox DigiSwitch V2 ist die zweite Generation des weltweit bekannten PowerBox DigiSwitch. Der PowerBox DigiSwitch ist aufgrund seiner kompakten Bauform und der vielseitigen Einsatzmöglichkeiten schon seit gut 15 Jahren der Standard in kleinen bis mittelgroßen Modellen.Der DigiSwitch V2 konnte dank dem Einsatz modernster Bauelemente um ganze 20 % verkleinert werden.Durch den Einsatz eines edlen, gefrästen und eloxierten Aluminiumgehäuses wur-de die nutzbare Kühlleistung deutlich erhöht – der PowerBox DigiSwitch V2 kann ca. 20 % mehr Dauerstrom leisten! Die kurzzeitige Belastbarkeit hat sich sogar ver-doppelt – über mehrere Sekunden verkraftet der DigiSwitch V2 über 10 A!Der DigiSwitch V2 hat vier wählbare Ausgangsspannungen – für normale Servos kann auf 6,0 V geregelt werden, für HV Servos stehen geregelte 7,0 V, 7,6 V oder eine Option ohne Regelung zur Verfügung.Als Stromversorgung kann zwischen vier verschiedenen Akkutypen gewählt wer-den: LiPo, LiIon, LiFePo und NiMh. Zur Spannungsanzeige der Akkus kommen ul-trahelle RGB LED´s zum Einsatz, die mit verschiedenen Farben den Ladestatus der Akkus signalisieren.Für CORE Kunden gibt es noch ein besonderes Feature oben drauf: die Akku- und Reglerspannungen können per Telemetrie direkt auf dem Sender angezeigt wer-den!FEATURES+ Leistungsstarker elektronischer Schalter+ Sehr leichte und kompakte Bauform+ Geregelte Ausgangsspannung+ Einstellbare Ausgangsspannung 6,0 V, 7,0 V, 7,6 V oder ungeregelt+ RGB-LED-Spannungsanzeige für die Batterie+ Telemetrie-Unterstützung für die CORE+ 4 Akkutypen werden unterstützt: 2s LiPo, 2s LiIon, 2s LiFePo and 5s NiMH+ Reglerüberwachung+ Unterdrückung von Servo-Rückströmen1. AUFBAU UND ANSCHLÜSSE2. EINBAU UND ANSCHLIESSEN DER AKKUSDer PowerBox DigiSwitch V2 wird an einer schwingungsarmen Stelle im Modell eingebaut. Reine GfK-Seitenwände eines Motormodells sollten mit einem 3 – 4 mm starken Sperrholzbrett, das von innen eingeklebt wird, gestützt werden, um Vibrati-onen zu minimieren und den Schrauben sicheren Halt zu geben.Stecken Sie einen Akku Ihrer Wahl – richtig gepolt – an den Akkueingang an. Es können 2s LiPo/LiIon, 2s LiFePo oder 5s NiMH Akkus verwendet werden. Wir emp-fehlen Ihnen den Einsatz der PowerPak 2.5x2 Pro Akkus, die dank der integrierten Ladetechnik besonders sicher und einfach in der Handhabung sind.Akkuanschluss (MPX oder JR)ZustandsanzeigeTelemetriean-CORE P²BUSHinweis bei selbst konfigurierten Akkupacks: Wird der Akku falsch gepolt an-gesteckt, sind die eingebauten Linear- Regler sofort zerstört!Der Ausgang des DigiSwitch wird am Akku Eingang oder in einen freien Steckplatz im Empfänger eingesteckt.Sollte kein Servoausgang mehr frei sein, kann ein V-Kabel an einen Servoausgang angesteckt werden, um den DigiSwitch V2 und das Servo anzuschließen.Beim CORE System verfahren Sie wie oben, das Kabel mit der einzelnen Signallei-tung wird in den P²BUS Eingang des Empfängers gesteckt.3. EIN- UND AUSSCHALTVORGANGWie beim Vorgängermodell und allen PowerBox Geräten mit einer Taste ist der Ein- und Ausschaltvorgang wie folgt:Drücken Sie die Taste ein bis zwei Sekunden, bis die LED´s violett leuchten, lassen Sie die Taste kurz los und bestätigen Sie mit einem zweiten, kurzen Tastendruck den Schaltvorgang.Einmal eingeschaltet kann der Schalter nur wieder mit dem Taster ausgeschaltet werden. Wackelkontakte oder Unterbrechungen während des Betriebes führen nicht zu einem Ausschalten der PowerBox. Der letzte Schaltzustand wird immer abgespeichert.4. EINSTELLEN DER AKKUANZEIGEDamit die LED Akkuanzeige richtig funktioniert, müssen Sie den Akkutyp einstellen. Dazu schalten Sie zuerst die PowerBox ein. Jetzt drücken Sie erneut die Taste und halten diese gedrückt.Nach ca. 5 Sekunden schalten sich die LED´s aus und eine Sequenz mit verschie-denen Farben beginnt. Jede Farbe ist einem Akkutyp zugeordnet. Lassen Sie die Taste los, wenn die Farbe angezeigt wird, die Ihrem Akkutyp entspricht. Der Akku-typ wird damit abgespeichert.Information zur LED Anzeige: Die Anzeige ist nicht linear zur Akkuspannung. Es wurden verschiedene gängige Akkutypen vermessen, die im Mittel eine Entlade-kurve ergeben. Diese Entladekurve wird verwendet, um eine prozentuale Anzeige zu ermöglichen.Die LED Anzeige hat folgende Bedeutung für den Akkuinhalt:80 – 100 %60 – 80 %40 – 60 %20 – 40 %0 – 20 % 5. EINSTELLEN DER AUSGANGSSPANNUNGDer PowerBox DigiSwitch V2 kann auf zwei verschiedene Ausgangsspannungen eingestellt werden: zum einen auf 6,0 V für reguläre Servos und zum anderen auf 7,0 V, 7,6 V oder ganz ungeregelt für HV Servos. Achten Sie bei dieser Einstellung darauf, dass alle angeschlossenen Komponenten hochvolt-tauglich sind.Ein Vorteil daran, die Spannung auf 7,6 V zu regeln, statt die Akkuspannung einfach durchzulassen, besteht darin, dass die anfänglich nach dem Laden vorhandene hohe Akkuspannung ausgeregelt wird. Somit erhält man von Anfang an eine kons-tante Spannung und damit eine länger gleichbleibende Servogeschwindigkeit- und Kraft.Zum Umstellen der Ausgangsspannung drücken Sie die Taste und stecken bei ge-drückter Taste den Akku ein. Die LED wird zuerst grün leuchten, nach 3 Sekunden rot. Je nachdem, bei welcher Farbe Sie loslassen, stellt sich die Ausgangsspan-nung um. Dabei bedeutet grün = 6,0 V, orange = 7,0 V, violett = 7,6 V und rot = ungeregelt.Abschließend blinkt die LED weiß, um den Einstellvorgang zu bestätigen.Hinweise zur Reglerleistung:Der maximale Strom, den der PowerBox DigiSwitch V2 abgeben kann, ist von äu-ßeren Faktoren wie Akkutyp, eingestellter Ausgangsspannung, und auch stark von der Kühlung abhängig. Im Idealfall ist die Weiche außen am Modell angebracht oder innen so verbaut, dass zumindest ein leichter Fahrtwind für Kühlung sorgt. Besonders wenn der DigiSwitch V2 mit LiPo/LiIon Zellen mit 6,0 V Ausgangsspan-nung betrieben wird, sollte die Anzahl der angeschlossenen Servos im empfohle-nen Rahmen bleiben. Wobei auch hier gilt, dass z.B. 6 kleine Flächenservos weniger Leistung brauchen als 4x 30 kg Servos.In der 7,6 V oder offenen Einstellung muss der DigiSwitch kaum oder gar nicht regeln und Energie vernichten. Damit steigt die Ausgangsleistung des PowerBox DigiSwitch V2 deutlich an! Das gleiche gilt für die 6,0 V Einstellung, wenn LiFePo oder NiMh Akkus verwendet werden, die bereits mit niedriger Eingangsspannung an dem Eingang des DigiSwitch angeschlossen werden.Sollten Sie sich nicht sicher sein, ob der PowerBox DigiSwitch V2 Ihren Stroman-forderungen gewachsen ist, bewegen Sie alle Servos am Boden für ca. 30 Sekun-den. Sollte sich der DigiSwitch stark erhitzen (über 60 °C), sollten Servos, Gestänge und Anlenkungen überprüft werden. Ist hier alles in Ordnung, sollte die für größere Leistungen konzipierte PowerBox Sensor verwendet werden.6. REGLERFEHLERDer Spannungsregler wird ständig auf Funktion überwacht. Sollte sich die Aus-gangsspannung außerhalb der Sollspannung befinden, wird das durch schnelles violettes Blinken der LED´s angezeigt. Reglerfehler treten z.B. nach verpoltem Ein-stecken der Akku auf.In dem Fall wenden Sie sich bitte an den Service!7.

box2d入门教程
Box2DFlash v2.0.2User manualLargely cribbed unauthorized from the Box2D manual,copyright2007-2009Erin Catto. AboutBox2DFlash is a2D rigid body simulation library for games.Programmers can use it in their games to make objects move in believable ways and make the world seem more interactive.From the game's point of view a physics engine is just a system for procedural animation.Rather than paying(or begging)an animator to move your actors around,you can let Sir Isaac Newton do the directing.Box2DFlash is written in AS3,and resides in the Box2d namespace.Most of the types defined in the engine begin with the b2prefix,to match the C++version.PrerequisitesIn this manual I'll assume you are familiar with basic physics concepts,such as mass, force,torque(扭转力）,and impulses（推力）.If not,please first consult（翻阅）the many tutorials provided by Chris Hecker and David Baraff(google these names).You do not need to understand their tutorials in great detail,but they do a good job of laying out the basic concepts that will help you use Box2D.Wikipedia is also an excellent source of physics and mathematics knowledge.In some ways it is more useful than Google,because it has carefully crafted content.This is not a prerequisite,but if you are curious about the inner workings of Box2D,you can look at these articles.Since Box2DAS3is written in Actionscript3,you are expected to be experienced in this.If you come from an AS2background,you may find it easier to start on an easier project before using Box2D,but it is not impossible.Core ConceptsBox2D works with several fundamental objects.We briefly define these objects here and more details are given later in this document.rigid body（刚体）A chunk of matter（物质）that is so strong that the distance between any two bits ofmatter on the chunk is completely constant.They are hard like a diamond.In the following discussion we use body interchangably with rigid body.shapeA2D piece of collision geometry that is rigidly attached to a body.Shapes have material properties of friction and restitution.（依附于body的2d碰撞几何结构，具有摩擦和恢复特性）Constraint（约束）A constraint is a physical connection that removes degrees of freedom from bodies.In2D a body has3degrees of freedom.If we take a body and pin it to the wall(like a pendulum)we have constrained the body to the wall.At this point the body can only rotate about the pin,so the constraint has removed2degrees of freedom.contact constraint（接触约束）A special constraint designed to prevent penetration（穿透）of rigid bodies and tosimulate（模仿）friction and restitution.You will never create a contact constraint,they are created automatically by Box2D.jointThis is a constraint used to hold two or more bodies together.Box2D supports these joint types:revolute,prismatic,distance,and more.Joints may support limits and motors.joint limitA joint limit restricts the range of motion of a joint.For example,the human elbow onlyallows a certain range of angles.joint motorA joint motor drives the motion of the connected bodies according to the joint'sdegrees of freedom.For example,you can use a motor to drive the rotation of an elbow.worldA physics world is a collection of bodies,shapes,and constraints that interact together.Box2D supports the creation of multiple worlds,but this is usually not necessary or desirable.Hello Box2DThis is a small example program that creates a large ground box and a small dynamic box. This code does not contain any graphics,so prepare to be underwelmed.:).The matching documents for this example have yet to be created.Creating a WorldEvery Box2D program begins with the creation of a world object.This is the physics hub that manages objects,and simulation.To create a world object,first we need to define a bounding box for the world.Box2D uses the bounding box to accelerate collision detection.The size isn't critical,but a better fit will improve performance.It is better to make the box too big than to make it too small.view sourceprint?1varworldAABB:b2AABB=newb2AABB();2worldAABB.lowerBound.Set(-100.0,-100.0);3worldAABB.upperBound.Set(100.0,100.0);CautionThe world AABB should always be bigger then the region where your bodies are located. It is better to make the world AABB too big than too small.If a body reaches the boundary of the world AABB it will be frozen and will stop simulating.Next we define the gravity vector.Yes,you can make gravity go sideways(or you could just rotate your monitor).Also we tell the world to allow bodies to sleep when they come to rest.A sleeping body doesn't require any simulation.view sourceprint?1vargravity:b2Vec2=newb2Vec2(0.0,-10.0);2vardoSleep:Boolean=true;Now we create the world object.view sourceprint?1varworld:b2World=newb2World(worldAABB,gravity,doSleep);So now we have our physics world,let's start adding some stuff to it.Creating a Ground BoxBodies are built using the following steps:1Define a body with a position,damping,etc.2Use the world object to create the body.3Define shapes with geometry,friction,density,etc.4Create shapes on the body.5Optionally adjust the body's mass to match the attached shapes.For step1we create the ground body.For this we need a body definition.With the body definition we specify the initial position of the ground body.view sourceprint?1vargroundBodyDef:b2BodyDef=newb2BodyDef();2groundBodyDef.position.Set(0.0,-10.0);For step2the body definition is passed to the world object to create the ground body. The world object does not keep a reference to the body definition.The ground body is created as a static body.Static bodies don't collide with other static bodies and are immovable.Box2D determines that a body is static when it has zero mass.Bodies have zero mass by default,therefore they are static by default.view sourceprint?1vargroundBody:b2Body=world.CreateBody(groundBodyDef);For step3we create a ground polygon definition.We use the SetAsBox shortcut to formthe ground polygon into a box shape,with the box centered on the origin of the parent body.view sourceprint?1vargroundShapeDef:b2PolygonDef=newb2PolygonDef();2groundShapeDef.SetAsBox(50.0,10.0);The SetAsBox function takes the half-width and half-height.So in this case the ground box is100units wide(x-axis)and20units tall(y-axis).Box2D is tuned for meters, kilograms,and seconds.So you can consider the extents to be in meters.However,it is possible to change unit systems,as discussed later in this document.We finish the ground body in step4by creating the ground polygon shape on the ground body.view sourceprint?1groundBody.CreateShape(groundShapeDef);Again,Box2D does not keep a reference to the shape or body definitions.It copies the data into the b2Body structure.Note that every shape must have a parent body,even shapes that are static.However, you can attach all static shapes to a single static body.This need for static bodies is done to make the Box2D code more uniform internally,reducing the number of potential bugs.You might notice a pattern here.Most Box2D types are prefixed with b2.This is done to reduce the chance for naming conflicts with your code.Creating a Dynamic BodySo now we have a ground body.We can use the same technique to create a dynamic body.The main difference,besides dimensions,is that we must establish the dynamic body's mass properties.First we create the body using CreateBody.view sourceprint?1varbodyDef:b2BodyDef=newb2BodyDef();2bodyDef.position.Set(0.0,4.0);34varbody:b2Body=world.CreateBody(bodyDef);Next we create and attach a polygon shape.Notice that we set density to1.The default density is zero.Also,the friction on the shape is set to0.3.Once the shape is attached, we instruct the body to compute it's mass properties from the attached shapes using the method SetMassFromShapes.This gives you a hint that you can attach more than one shape per body.If the computed mass is zero,then the body becomes truly static.Bodies have a mass of zero by default,that's why we didn't need to call SetMassFromShapes for the ground body.view sourceprint?1varshapeDef:b2PolygonDef=newb2PolygonDef();2shapeDef.SetAsBox(1.0,1.0);3shapeDef.density=1.0;4shapeDef.friction=0.3;5body.CreateShape(shapeDef);6body.SetMassFromShapes();That's it for initialization.We are now ready to begin simulating.Simulating the World(of Box2D)So we have initialized the ground box and a dynamic box.Now we are ready to set Newton loose to do his thing.We just have a couple more issues to consider.Box2D uses a bit of numerical code called an integrator.Integrators simulate the physics equations at discrete points of time.This goes along with the traditional game loop where we essentially have a flip book of movement on the screen.So we need to pick a time step for Box2D.Generally physics engines for games like a time step at least as fast as60Hz or1/60seconds.You can get away with larger time steps,but you will have to be more careful about setting up the definitions for your world.We also don't like the time step to change much.So don't tie the time step to your frame rate(unless you really,really have to).Without further ado,here is the time step.view sourceprint?1vartimeStep:Number=1.0/60.0;In addition to the integrator,Box2D also uses a larger bit of code called a constraint solver.The constraint solver solves all the constraints in the simulation,one at a time.A single constraint can be solved perfectly.However,when we solve one constraint,we slightly disrupt other constraints.To get a good solution,we need to iterate over all constraints a number of times.The suggested iteration count for Box2D is10.You can tune this number to your liking,just keep in mind that this has a trade-off between speed and ing fewer iterations increases performance but accuracy suffers. Likewise,using more iterations decreases performance but improves the quality of your simulation.Here is our chosen iteration count.view sourceprint?1variterations:Number=10;Note that the time step and the iteration count are completely unrelated.An iteration is not a sub-step.One iteration is a single pass over all the constraints withing a time step. You can have multiple passes over the constraints within a single time step.We are now ready to begin the simulation loop.In your game the simulation loop can be merged with your game loop.In each pass through your game loop you call b2World.Step.Just one call is usually enough,depending on your frame rate and your physics time step.The Hello World program was designed to be dead simple,so it has no graphical output. Rather that being utterly boring by producing no output,the code prints out the position and rotation of the dynamic body.Yay!Here is the simulation loop that simulates60time steps for a total of1second of simulated time.view sourceprint?1for(vari:Number=0;i<60;++i)23{4world.Step(timeStep,iterations);5varposition:b2Vec2=body.GetPosition();6varangle:Number=body.GetAngle();7trace(position.x+','+position.y+','+angle);89}The TestbedOnce you have conquered the HelloWorld example,you should start looking at Box2DAS3's testbed.The testbed is a unit-testing framework and demo environment. Here are some of the features:•Mouse picking of shapes attached to dynamic bodies.•Extensible set of tests.The testbed has many examples of Box2D usage in the test cases and the framework itself.I encourage you to explore and tinker with the testbed as you learn Box2D.API DesignMemory ManagementBox2dFlash is a straight port of Box2D,a C++library.Hence in many places,memory is managed precisely,rather than relying on the garbage collector.This helps reduce stutter. Objects are recycled,hence the many Create/Destroy methods.Factories and DefinitionsAs mentioned above,memory management plays a central role in the design of the Box2D API.So when you create a b2Body or a b2Joint,you need to call the factoryfunctions on b2World.There are creation functions:view sourceprint?1b2World.CreateBody(def:b2BodyDef):b2Body2b2World.CreateJoint(def:b2JointDef):b2JointAnd there are corresponding destruction functions:view sourceprint?1b2World.DestroyBody(body:b2Body):void23b2World.DestroyJoint(joint:b2Joint):voidWhen you create a body or joint,you need to provide a definition or def for short. These definitions contain all the information needed to build the body or joint.By using this approach we can prevent construction errors,keep the number of function parameters small,provide sensible defaults,and reduce the number of accessors.Since shapes must be parented to a body,they are created and destroyed using a factory method on b2Body:view sourceprint?1b2Body.CreateShape(def:b2ShapeDef):b2Shape2b2Body.DestroyShape(shape:b2Shape):voidFactories do not retain references to the definitions.So you can create definitions on the stack and keep them in temporary resources.UnitsBox2D works with floating point numbers,so some tolerances have to be used to make Box2D perform well.These tolerance have been tuned to work well with meters-kilogram-second(MKS)units.In particular,Box2D has been tuned to work well with moving objects between0.1and10meters.So this means objects between soup cans and buses in size should work well.Being a2D physics engine it is tempting to use pixels as your units.Unfortunately this will lead to a poor simulation and possibly weird behavior.An object of length200pixels would be seen by Box2D as the size of a45story building.Imagine trying to simulate the movement of a high-rise building with an engine that is tuned to simulate ragdolls and barrels.It isn't pretty.***Caution***Box2D is tuned for MKS units.Keep the size of moving objects roughly between0.1and10meters.You'll need to use some scaling system when you render your environment and actors.The built in DebugDraw already features a scaling factor.User DataThe b2Shape,b2Body,and b2Joint classes allow you to attach any object as user data. This is handy when you are examining Box2D data structures and you want to determine how they relate to the data structures in your game engine.For example,it is typical to attach an actor to the rigid body on that actor.This sets up a circular reference.If you have the actor,you can get the body.If you have the body,you can get the actor.view sourceprint?1actor:GameActor=newGameCreateActor();2bodyDef:b2BodyDef=newb2BodyDef();erData=actor;4actor.body=box2Dworld.CreateBody(bodyDef);Here are some examples of cases where you would need the user data:•Applying damage to an actor using a collision result.•Playing a scripted event if the player is inside an axis-aligned box.•Accessing a game structure when Box2D notifies you that a joint is going to be destroyed.Keep in mind that user data is optional and you can put anything in it.However,you should be consistent.For example,if you want to store an actor on one body,you should probably keep an actor on all bodies.StrawmanIf you don't like this API design,that's ok!You have the source code!Seriously,if you have feedback about anything related to Box2D,please leave a comment in the forum.The WorldAboutThe b2World class contains the bodies and joints.It manages all aspects of the simulation and allows for asynchronous queries(like AABB queries).Much of your interactions with Box2D will be with a b2World object.Creating and Destroying a WorldCreating a world is fairly simple.You need to provide a bounding box and a gravity vector.The axis-aligned bounding box should encapsulate the world.You can improve performance by making the bounding box a bit bigger than your world,say2x just to be safe.If you have lots of bodies that fall into the abyss,your application should detect this and remove the bodies.This will improve performance and prevent floating point overflow.view sourceprint?1varmyWorld:b2World=newb2World(aabb,gravity,doSleep)When myWorld goes out of use,it will automatically be deleted by the garbage collector.CautionRecall that the world AABB should always be bigger then the region where your bodies are located.If bodies leave the world AABB,then they will be frozen.This is not a bug.Using a WorldThe world class contains factories for creating and destroying bodies and joints.These factories are discussed later in the sections on bodies and joints.There are some other interactions with b2World that I will cover now.SimulationThe world class is used to drive the simulation.You specify a time step and an iteration count.For example:view sourceprint?1vartimeStep:Number=1.0/60.;2variterationCount:Number=10;3myWorld.Step(timeStep,iterationCount);After the time step you can examine your bodies and joints for information.Most likely you will grab the position off the bodies so that you can update your actors and render them.You can perform the time step anywhere in your game loop,but you should be aware of the order of things.For example,you must create bodies before the time step if you want to get collision results for the new bodies in that frame.As I discussed above in the HelloWorld tutorial,you should use a fixed time step.By using a larger time step you can improve performance in low frame rate scenarios.But generally you should use a time step no larger than1/30seconds.A time step of1/60 seconds will usually deliver a high quality simulation.The iteration count controls how many times the constraint solver sweeps over all the contacts and joints in the world.More iterations always yields a better simulation.But don't trade a small time step for a large iteration count.60Hz and10iterations is far better than30Hz and20iterations.Exploring the WorldAs mentioned before,the world is a container for bodies and joints.You can grab the body and joint lists off the world and iterate over them.For example,this code wakes up all the bodies in the world.view sourceprint?1for(varb:b2Body=myWorld.GetBodyList();b;b=b.GetNext())23{4 b.WakeUp();5}Unfortunately life can be more complicated.For example,the following code is broken:view sourceprint?01for(varb:b2Body=myWorld.GetBodyList();b;b=b.GetNext())0203{04varmyActor:GameActor=b->GetUserData()asGameActor;05if(myActor.IsDead())06{07myWorld.DestroyBody(b);//ERROR:now GetNext returns garbage. 0809}10}Everything goes ok until a body is destroyed.Once a body is destroyed,its next pointer becomes invalid.So the call to b2Body.GetNext()will return garbage.The solution to this is to copy the next body before destroying the body.view sourceprint?01varnode:b2Body=myWorld.GetBodyList();02while(node)0304{05varb:b2Body=node;06node=node.GetNext();0708varmyActor:GameActor=b->GetUserData()asGameActor;09if(myActor.IsDead())1011{12myWorld.DestroyBody(b);13}14}This safely destroys the current body.However,you may want to call a game function that may destroy multiple bodies.In this case you need to be very careful.The solution is application specific,but for convenience I'll show one method of solving the problem.view sourceprint?01varnode:b2Body=myWorld.GetBodyList();02while(node)0304{05varb:b2Body=node;06node=node.GetNext();0708varmyActor:GameActor=b.GetUserData()asGameActor;09if(myActor.IsDead())1011{12varotherBodiesDestroyed:Boolean=GameCrazyBodyDestroyer(b); 13if(otherBodiesDestroyed)14{1516node=myWorld.GetBodyList();17}18}19}Obviously to make this work,GameCrazyBodyDestroyer must be honest about what it has destroyed.AABB QueriesSometimes you want to determine all the shapes in a region.The b2World class has a fast log(N)method for this using the broad-phase data structure.You provide an AABB in world coordinates and b2World returns an array of all the shapes that potentially intersect the AABB.This is not exact because what the function actually does is return all the shapes whose AABBs intersect the specified AABB.For example,the following code finds all the shapes that potentially intersect a specified AABB and wakes up all of the associated bodies.view sourceprint?01varaabb:b2AABB=newb2AABB();02aabb.lowerBound.Set(-1.0,-1.0);03aabb.upperBound.Set(1.0,1.0);0405vark_bufferSize:Number=10;06varbuffer:Array=[];07varcount:Number=myWorld.Query(aabb,buffer,k_bufferSize);0809for(vari:Number=0;i<count;++i)10{11buffer[i].GetBody().WakeUp();1213}Note:This calling syntax is rather obscure for typical AS3use.This is due to Box2DAS3's C++heritage,which does not handle variable sized arrays so easily.BodiesAboutBodies have position and velocity.You can apply forces,torques,and impulses to bodies. Bodies can be static or dynamic.Static bodies never move and don't collide with other static bodies.Bodies are the backbone for shapes.Bodies carry shapes and move them around in the world.Bodies are always rigid bodies in Box2D.That means that two shapes attached to the same rigid body never move relative to each other.You usually keep pointers to all the bodies you create.This way you can query the body positions to update the positions of your graphical entities.You should also keep body pointers so you can destroy them when you are done with them.Body DefinitionBefore a body is created you must create a body definition(b2BodyDef).You can create a body definition on the stack or build it into your game's data structures.The choice is up to you.Box2D copies the data out of the body definition,it does not keep a pointer to the body definition.This means you can recycle a body definition to create multiple bodies.Lets go over some of the key members of the body definition.Mass PropertiesThere are a few ways to establish the mass properties for a body.6Set the mass properties explicitly in the body definition.7Set the mass properties explicitly on the body(after it has been created).8Set the mass properties based on the density of the attaced shapes.In many game scenarios it makes sense to compute mass based on shape densities.This helps to ensure that bodies have reasonable and consistent mass values.However,other game scenarios may require specific mass values.For example,you may have a mechanism,like a scale that needs precise mass values.You can explicitly set the mass properties in the body definition as follows:view sourceprint?1bodyDef.massData.mass=2.0;//the body's mass in kg23bodyDef.massData.center.SetZero();//the center of mass in local coordinates4bodyDef.massData.I=3.0;//the rotational inertia in kg*m^2.The other methods of setting the mass properties are covered elsewhere in this document.Position and AngleThe body definition gives you the chance to initialize the position of the body on creation. This has better performance than creating the body at the world origin and then moving the body.A body has two main points of interest.The first point is the body's origin.Shapes and joints are attached relative to the body's origin.The second point of interest is the center of mass.The center of mass is determined from mass distribution of the attached shapes or is explicitly set with b2MassData.Much of Box2D's internal computations use the center of mass position.For example b2Body stores the linear velocity for the center of mass.When you are building the body definition,you may not know where the center of mass is located.Therefore you specify the position of the body's origin.You may also specify the body's angle in radians,which is not affected by the position of the center of mass.If you later change the mass properties of the body,then the center of mass may move on the body,but the origin position does not change and the attached shapes and joints do not move.view sourceprint?1bodyDef.position.Set(0.0,2.0);//the body's origin position.2bodyDef.angle=0.25*b2Settings.b2_pi;//the body's angle in radians.DampingDamping is used to reduce the world velocity of bodies.Damping differs from friction in that friction only occurs when two surfaces are in contact.Damping is also much cheaper to simulate than friction.Note,however,that damping is not a replacement for friction; the two effects should be used together.Damping parameters should be between0and infinity,with0meaning no damping,and infinity meaning full damping.Normally you will use a damping value between0and1.0.I generally do not use linear damping because it makes bodies look floaty.view sourceprint?1bodyDef.linearDamping=0.0;2bodyDef.angularDamping=0.1;Damping is approximated for stability and performance.At small damping values the damping effect is mostly independent of the time step.At larger damping values,the damping effect will vary with the time step.This is not an issue if you use a fixed time step(recommended).Sleep ParametersWhat does sleep mean?Well it is expensive to simulate bodies,so the less we have to simulate the better.When a body comes to rest we would like to stop simulating it.When Box2D determines that a body(or group of bodies)has come to rest,the body enters a sleep state which has very little CPU overhead.If an awake body collides with a sleeping body,then the sleeping body wakes up.Bodies will also wake up if a joint or contact attached to them is destroyed.You can also wake a body manually.The body definition lets you specify whether a body can sleep and whether a body is created sleeping.view sourceprint?1bodyDef.allowSleep=true;2bodyDef.isSleeping=false;BulletsGame simulation usually generates a sequence of images that are played at some frame rate.In this setting rigid bodies can move by a large amount in one time step.If a physics engine doesn't account for the large motion,you may see some objects incorrectly pass through each other.This effect is called tunneling.By default,Box2D uses continuous collision detection(CCD)to prevent dynamic bodies from tunneling through static bodies.This is done by sweeping shapes from their old position to their new positions.The engine looks for new collisions during the sweep andcomputes the time of impact(TOI)for these collisions.Bodies are moved to their first TOI and then simulated to the end of the original time step.This process is repeated as necessary.Normally CCD is not used between dynamic bodies.This is done to keep performance reasonable.In some game scenarios you need dynamic bodies to use CCD.For example, you may want to shoot a high speed bullet at a thin wall.Without CCD,the bullet my tunnel through the wall.Fast moving objects in Box2D are called bullets.You should decide what bodies should be bullets based on your game design.If you decide a body should be treated as a bullet, use the following setting.view sourceprint?1bodyDef.isBullet=true;The bullet flag only affects dynamic bodies.CCD is expensive so you probably don't want all moving bodies to be bullets.So by default Box2D only uses CCD between moving bodies and static bodies.This is an effective approach to prevent bodies from escaping your game world.However,you may have some fast moving bodies that that require CCD all the time.Body FactoryBodies are created and destroyed using a body factory provided by the world class.This lets the world create the body with an efficient allocator and add the body to the world data structure.Bodies can be dynamic or static depending on the mass properties.Both body types use the same creation and destruction methods.view sourceprint?1vardynamicBody:b2Body=myWorld.CreateBody(bodyDef);23//...do stuff...4myWorld.DestroyBody(dynamicBody);5dynamicBody=null;Static bodies do not move under the influence of other bodies.You may manually move static bodies,but you should be careful so that you don't squash dynamic bodies between two or more static bodies.Friction will not work correctly if you move a static body.Static bodies never simulate on their own and they never collide with other static bodies.It is faster to attach several shapes to a static body than to create several static bodies with a single shape on each one.Internally,Box2D sets the mass and inverse mass of static bodies to zero.This makes the math work out so that most algorithms。

1. Box2D v2.1.0用户手册翻译 - 目录，第01章 导言(Introduction)网上已经有个Box2D用户手册的翻译，但是基于v2.0.1，跟最新手册有很多不对应。
在这里决定将文档的全文再翻译出来，更准确的说是根据网上流传的v2.0.1版本，将最新文档重新整理一遍。
很多内容是直接复制自Aman JIANG(江超宇)翻译的Box2D v2.0.1 用户手册Box2D v2.1.0 用户手册版权 2007-2010 Erin Catto第01章 导言(Introduction)第02章 Hello Box2D第03章 公共模块(Common)第04章 碰撞模块(Collision Module)第05章 动态模块(Dynamics Module)第06章 夹具(Fixtures)第07章 物体(Bodies)第08章 关节(Joints)第09章 接触(Contacts)第10章 世界(World Class)第11章 杂项(Loose Ends)第12章 调试绘图(Debug Drawing)第13章 限制(Limitations)第14章 参考(References)第01章 导言(Introduction)1.1 关于Box2D是个二维刚体仿真库, 用于编写游戏。
程序员可以使用它, 让游戏中的物体运动起来更真实, 让游戏世界更具交互性。
以游戏的角度来看，物理引擎只是个程序性动画系统。
(procedural animation)(译注: 做动画常有两种方法, 一种是预先准备好动画所需的数据，比如图片，再一帧一帧地播放。
另一种是以一定方法，动态计算出动画所需的数据，根据数据再进行绘图。
从这种角度看，预先准备的，可称为数据性动画，动态计算的可称为程序性动画。
这个区别，就类似以前我们做历史题和数学题，做历史题，记忆很重要，也就是答案需要预先准备好的。
做数学题，方法就很重要，答案是需要用方法推导出来的。

打开flywireless6.0之后再将设备插入电脑，等待设备软件自启动，如未启动，则在桌面选择打开。
等其显示可连接状态之后，在flywireless6.0的设备里点击添加设备User Equipment 选择QualCommLTE，Network Adapter选择Quanta-CMCC-Broadband RmNET Adapter，之后查看端口信息，AT Port选择Quanta-CMCC-Modem，Bth/Trace Port选择Quanta-CMCC-Diagnostic Interfce，如下图。
点击增加，然后连接设备。
成功后，点到测试任务，添加任务选择Ftp下载测试，设备选为MS1,APN接点选为CTNET,用户个数10，下载时长0，是否连续下载是（其他配置按需求配置），填写服务器地址用户名密码及本地保存地址，连接服务器（此时会自动连接网络），选择服务器文件，确定（此时会断网），填写任意任务名，增加。
如下图。
将此任务打上勾，点击开始测试（第一次点击测试之后才会连接网络，之后网络会保持连接）保存配置，这样就能做业务了。
有时没有速率是因为服务器文件不在了，需要重新选择。
DBOX一代、二代机器的使用评测
DBOX一代、二代机器的使用评测作者：来源：《卫星电视与宽带多媒体》2013年第06期外观方面：先说下一代：（也叫D500HD）我对DBOX一代不感兴趣，觉得一代机外观设计太简单了，和DM558s一样。
硬件软件好坏还是另一回事不评论，给人第一感觉不是很高档的机器。
相对于DBOX一代来说DBOX二代机（D800HD）就不是这么感觉了，那废话就不多说了，下面来看看2台样机测试此次的外观方面评测：包装：两台机子都是黑色的包装和dm800HD还有几分相似，DBOX一代盒子（长：32cm 宽：19cm高：7cm）四周都是DBOXD500HD而DBOX二代盒子（长：33.5cm宽：23cm高：7cm）四周都是DBOX D800HD够大够简约，盒子底部是些机子的英文参数，看来这机子也是出口版。
打开盒子我们看到一本黑黑的英文说明书在塑料袋内，（图3）（图4）这个直接可以扔在一旁，机子并没有像其它机一样用气泡垫包装或发泡塑料纸包装，这个太没保护意识了，不利于快递运输。
一旁有条随机附送的HD高清线，是很次的那种线，送的么也就不要求太高了，总比有些平民高清机只送条AV线要来得好吧！取出机子，高清线。
遥控器藏在右边白色的纸夹内。
外观：DBOX一代整机大小（图5）（长：20cm宽：14.5cm高：4cm），DBox二代整机大小（图6）（长：28cm宽：20cm高：6cm）2台机器对比如所示（图7），总体DBOX二代机器中规中距机子看起来还是蛮漂亮的。
一代机没显示屏，左边是个CA卡槽，只有一个待机按键，机子这么小样子，给人第一感觉不是很高档的机器，和普通的DM系列差不多挡次。
而二代机让大家更能清楚的看到面壳部分设计，（图6）上面贴着3块贴膜，这样的保护就到位了，不容易引起划伤，面板中间是个很大的显示屏，开机有电源和信号指示灯亮。
左边是一个待机按键和音量及节目按键，设计的过于简单，没有ok键和菜单键这2个特别重要的按键舍去实在是不应该。
