角色控制器组件

角色控制器组件 : 不会像rigidbody刚体被弹开, 穿模.

1. 在3d物体上添加"Character Controller"组件
2. isGrounded:判断是否在地面上
3. Move(Vector3 dir * speed Time.deltaTime):类似Transform.Translate,没有重力,需要传递一个方向和速度,所以**需要Time.deltaTime**
4. SimpleMove(Vector3 dir speed): 自带重力,本身按照时间来计算的,**不需要Time.deltaTime**

public class pilotController : MonoBehaviour {

	private CharacterController characterController;
	private Rigidbody rb;
	public int  moveSpeed = 1;
	public int rotateSpeed = 200;
	public int jumpSpeed = 8;
	private bool isGround = false;
	Vector3 dir = Vector3.zero;
	void Start () {
		characterController = GetComponent<CharacterController>();
		rb = GetComponent<Rigidbody>();
		//Debug.Log(characterController.isGrounded); //判断物体是否在地面
	}
	
	// Update is called once per frame
	void Update () {
        if (characterController.isGrounded)
        {
			float horizontal = Input.GetAxis("左右移动");
			float vertical = Input.GetAxis("前后移动");

			dir = new Vector3(horizontal,0,vertical);
			dir = transform.TransformDirection(dir);//物体xyz朝向随左右前后变化而变化
			transform.eulerAngles = new Vector3(0,transform.eulerAngles.y  + horizontal* Time.deltaTime* rotateSpeed, 0);
            if (Input.GetKeyDown(KeyCode.Space))
            {
                Debug.Log("跳跃");
            }
        }
        characterController.SimpleMove(dir * moveSpeed);
	}
}
