• unity3d 第一人称脚本解释:MouseLook

     4 /// MouseLook rotates the transform based on the mouse delta.
     5 /// Minimum and Maximum values can be used to constrain the possible rotation
     6 
     7 /// To make an FPS style character:
     8 /// - Create a capsule.
     9 /// - Add the MouseLook script to the capsule.
    10 ///   -> Set the mouse look to use LookX. (You want to only turn character but not tilt it)
    11 /// - Add FPSInputController script to the capsule
    12 ///   -> A CharacterMotor and a CharacterController component will be automatically added.
    13 
    14 /// - Create a camera. Make the camera a child of the capsule. Reset it's transform.
    15 /// - Add a MouseLook script to the camera.
    16 ///   -> Set the mouse look to use LookY. (You want the camera to tilt up and down like a head. The character already turns.)
