MouseLook Problem

/// MouseLook rotates the transform based on the mouse delta. /// Minimum and Maximum values can be used to constrain the possible rotation

/// To make an FPS style character: /// - Create a capsule. /// - Add a rigid body to the capsule /// - Add the MouseLook script to the capsule. /// -> Set the mouse look to use LookX. (You want to only turn character but not tilt it) /// - Add FPSWalker script to the capsule

/// - Create a camera. Make the camera a child of the capsule. Reset it's transform. /// - Add a MouseLook script to the camera. /// -> Set the mouse look to use LookY. (You want the camera to tilt up and down like a head. The character already turns.) [AddComponentMenu("Camera-Control/Mouse Look")] public class MouseLook : MonoBehaviour {
