Can scene camera follow the object?
There is a GameOjbect(walker) in My scene,and it move fast when in play mode, And I have to adjust other GameOjects' position around the walker, Can I use a script or something else to control the scene's camera (note:not the camera in play mode).
Can you explain that further? You say 'move fast when in play mode' but then 'not the camera in play mode'. Are you talking about the editor's camera(s)?
[EDIT: as of Unity 4.3, press Shift-F to lock the scene view to the selected object]
To control the SceneView's camera, you have to use some undocumented (and therefore: officially not supported) methods.
SceneView.lastActiveSceneView.camera.pivot allows you to directly alter the pivot point of the sceneView camera. Using some other standard camera functions this should allow you to do what you want.
Scripts using this need to be in an Editor folder.
If you really want to do this I suggest you decompile UnityEditor.dll and have a look in the SceneView and the Camera classes.
I just wrote a script that allows multiple SceneViews to follow a gameobject in edit and play mode. I uploaded it to the Unity3d Wiki: http://wiki.unity3d.com/index.php/SceneViewCameraFollower Check it out.
I'm not certain when this feature was introduced, but as of Unity 4.3 you can press Shift-F (or double-tap F) to lock the scene camera to the selected object. When the object moves, the scene camera will follow it.
See hotkey documentation.
"double-tap F " works!. The scene view camera follow the selected moving gameobject in the Play mode. By the way why this trick is undocumented. Thanks for the tips.
[Edit] In version Unity 2018.3 use "Shift" + "F" key to lock the camera to moving object. In the future version maybe unity will change back to double tap "F" again, but I'm not sure.
There's a script named 'SmoothFollow' in the standard assets. Add it to the camera and drag the object you want it to follow into the 'Target' slot of the script
