CharacterController 角色控制器

Inherits from Collider

A CharacterController allows you to easily do movement constrained by collisions without having to deal with a rigidbody.

角色控制器允许你在受制于碰撞的情况下很容易的进行运动，而不用处理刚体。

（个人理解：用CharacterController组件，它包含Rigidbody组件的一些属性，就不用用Rigidbody组件了）。

A CharacterController is not affected by forces and will only move when you call the Move funtion. It will then carry out the movement but be constrained by collisions.

角色控制器不受力的影响，仅仅当你调用Move函数时才运动。然后它将执行运动，但是受制于碰撞。

参考:Character animation examples

摘自网络的Physx参考：

character一般用于主角这类用户控制的物体，它不会受到scene的重力影响，不会被其他物体推。

程序中可以使用它的move方法移动它，当他碰到静态物体时，会停下来，遇到动态物体时会推开他，当然，这些都是可以通过activegroup来控制的。group最多有32组。因为他是一个NxU32，并通过每一位代表一个组。

move的一个参数用来告诉程序，character的当前状态。（collisionFlags）

当他遇到物体的时候，如果设置了回调函数，系统会通过回调函数通知程序。。(NxControllerDesc.callback)

character还有上楼梯模式，在某些高度的台阶，可以直接上去。(NxControllerDesc.stepOffset)

character还可以设置可以走上去的斜坡。（NxControllerDesc.slopeLimit）

由于character不受场景的重力影响，所以，用户要在move函数中自己添加重力因素，也就是说，character可以浮在空中，除非那里有其他activegroup物体。
