screenbutton = true; } } function OnGUI(){
if(screenbutton==true) if(GUI.Button(Rect(Screen.width/2-380,Screen.height/2-190,60,50),"Scene1")){
print("You click Scene1"); Application.LoadLevel (1); screenbutton = false; }else if(GUI.Button(Rect(Screen.width/2-380,Screen.height/2-130,60,50),"Scene2")){ print("You click Scene2"); Application.LoadLevel (2); screenbutton = false; }else if( GUI.Button(Rect(Screen.width/2-375,Screen.height/2-0,50,50),"Quit")){ print("You click Quit"); Application.Quit(); } } 心得：场景转换时，这个程序贴在按钮界面场景中。在 Build Setting（导出）（在 File 下）菜单中加入所需场景。
var particle : GameObject;
function Start(){ DontDestroyOnLoad(this); screnbutton=true;
word = Text; Text = ""; yield WaitForSeconds (2); TypeText ();

rigibody.AddForce(Vector3(0,0,power);//Time.deltaTime:每秒耗时 } 08,碰撞然后转到下一个场景 function OnCollisionEnter(theCollision:Collision){ if(=="Floor"){ Application.LoadLevel("name");//参数亦可以是int型的 } }
} 04,实例创建对象 GameObject g=Instantiate(PREFAB,Pos,transform.rotation); 05,简易定时器 var myTimer: float =5.0f; function Update(){ if(myTimer>0) myTimer-=Time.deltaTime;} if(myTimer<=0) Debug.log("Game End");} } 06,物体移动 var speed:float =5.0f; function Update(){ transform.Translate(Vector3(0,0,speed)*Time.deltaTime);//Time.deltaTime:每秒耗时 } 07，刚体向目标处移动 var power:float =500.0f; function Update(){

5.新建操作对象（立方体模拟人物）
1)Why：作为操作对象
2)How：Game object —create other —cube
3)Tip：在Hierarchy视图中选中Main Camera，有时会发现立方体并不在相机视线范围内，此时，有一个小技巧可以让Scene视图中所有对象在相机范围的中心（如果Scene视图中只有一个对象，则该对象居于相机范围的中心，如果有多个对象，则所有对象组合的中心位于相机的中心）：
Audio的常用属性含义如下：
Audio Clip：所要播放的声音片段
Mute：是否静音
Play on awake：是否在程序运行时自动播放（默认小，取值范围0.0--1.0（默认为1，最大音量）
Pitch：音频播放速度（默认为1，正常播放，小于1为慢速播放，大一1为加速播放）
public AudioSource music;
void OnGUI() {
if (GUI.Button(new Rect(0, 60, 100, 50), "Play"))
{
if(!music.isPlaying)
{
music.Play();
}
}
if (GUI.Button(new Rect(0, 120, 100, 50), "Pause"))
7.游戏音频
Audio Source
Audio Listener
Audio Source是我们所要播放的音频文件，而Audio Listener则是用来监听播放音频的。Unity3d支持四种格式的音频文件，即常用的MP3，wav格式和aiff，ogg格式。
How：由于audio属于组件(component)，所以需要绑定在对象上才能正常播放。我们可以把音频绑定在camera上，或许绑定在场景中的其他对象上，当然也可以将其绑定在一个空对象上。

GUI自适应屏幕
public override void GUIDraw (){
//开始缩放
//先定义一个标准屏幕大小代码按照这个分辨率写，这里屏是800*480象素，GUI矩阵再乘以新的缩放矩阵实现GUI的缩放，GUI.matrix*=scaleMatrix;
ScreenScaleUtil.BeginScreenScale ();
}
public static void EndScreenScale(){
if(lstMats.Count<=0)
return;
GUI.matrix=lstMats[lstMats.Count-1];
lstMats.RemoveAt(lstMats.Count-1);
}
}
1 GUI汇总
function OnGUI() {
GUI.matrix*=ScaleMatrix;
}
public static void BeginScreenScale(ScreenScaleType scaleType ){
if(lstMats.Count>0){s.Add(GUI.matrix);
GUI.matrix*=GetScreenScaleMatrix(screenSize,scaleType);
