Then press the Add Mesh button in the bottom left of the 3D Scene Editor (Meshes window), and choose the house object.然后点击三维场景编辑器左下角的Add Mesh按钮，然后选择house对象。

Navigation导航Now we're going to work through how to navigate and control this simple scene in the editor.The first control is the Select tool (press ESCAPE in the viewport to go back to this at any time). You can left click on and off the house to select/deselect it, or drag a box in the viewport to select all that fall within it.现在，学习怎么控制场景编辑器。

首先学习的是选择工具（在视图按ESC键随时回到这）。

你可以单击选择或取消房子。

或框选全部对象。

Right clicking in the viewport brings up a menu for the selected object.在视窗中右键会弹出一个选择对象的菜单。

If you're doing anything in a complicated scene and don't want to lose the selection, press the Lock Selection button (it's the padlock icon on the same strip as the Select tool) or just press the Ctrl L key to toggle it on and off (when the viewport has focus).如果你不想在一个复杂的场景工作，可以按下锁定选择按纽（在工具栏的挂锁图标）或者只是按下Ctrl+ L键来切换它。

Leave selection unlocked for the moment.You can now try moving, rotating and scaling the house Using the Gizmo.现在你可以尝试移动，旋转和缩放这些房子看Using the Gizmo.。

Mouse and arrow keys鼠标和方向键Holding down the right mouse button as you drag the mouse pans and tilts the camera. The mouse wheel zooms tighter and wider in steps. The up down arrow keys allow you to dolly closer and further from the house (back and forth). The right and left arrow keys allow you to track the camera side to side. With one hand driving the keys and one steering the mouse you can “fly” through the scene.按住鼠标右键是旋转相机。

鼠标滚轮滚动是缩放。

向上向下箭头键可让您远离和靠近房子。

进一步从房子来回。

左，右箭头键允许您跟踪摄像机从一边到另一边。

进一步从房子来回。

用一只手控制方向键，另一只手控制鼠标就可以在现场漫游。

Click on the scene off the house to de-select the house. 点击房子空白处取消选择房子。

Holding down the space bar and the left mouse button allows you to crane the camera position higher and lower.按住空格键和鼠标左键平移视图。

Setting up the Camera设置相机Before previewing your scene in the player it is a good idea to adjust the camera to your desired view. You can do this by selecting the camera in the objects list and moving it into position with the gizmo. You can also simply navigate in the viewport to your desired position for the camera and then use the Copy Viewport To Selected Camera option under the camera icon in the vertical toolbar (it's the fifth icon down).在播放器前预览你的场景是一个好主意，调整相机到您所需的视图。

您可以通过选择对象列表的相机和平移视图。

你可以仅在你的相机的所需位置的视图中航行和然后使用在工具栏camera图标（第5个图标）下的Selected Camera option under the camera。

Moving In the PlayerRun the scene by pressing the F12 key. The default light for the scene has ended up inside the house so the scene is dark except for the lit interior of the house.通过按F12键运行场景。

由于场景的默认灯光已经关闭，所以场景只有房子内部的灯光。

Tilt the camera so the open front door is centre of the screen. Press the “up” arrow key to move the position of the camera to the doorway. Level up with the right mouse key to look at the opposite interior wall. A slight move forward puts you in the centre of the house where you can look around at the interior.倾斜相机屏幕的中心，以便打开前门。

按“向上”箭头键移动相机的位置到门口。

用鼠标右键对着内墙，稍微向前移动到房子中心在内部四处观看。

Click the standard window “x” at the top right of the player window to close the scene and automatically take you back to the 3D work space (or just press ESCAPE).点击播放器窗口中的“x”图标关闭播放器并自动返回到3D工作区（或按下ESC）。

To the far left of the DX Studio user interface is the object menu. Select the light. Use the gizmo to put the light just outside the house.在DX Studio用户界面最左边的object窗口列表里。

选择灯光，使用操纵器移动灯光到房子的外面。

At the bottom of the vertical Tool bar there is an icon that looks like a pair of curved arrows. This is the “Orbit Selection (O)” button. Click on it or press the “O” key. Press the left mouse butto n and drag left/right, up and down. If the light is still selected the camera should snap to centre on it. Select the house and take a look around the outside of the house.在工具栏有一个叫“Orbit Selection (O)”的按纽。

点击它或按下“O”键。

按下鼠标左键并拖动。

如果灯光仍被选择摄像机捕捉到中心就可以了。
