unity3d自己写角色移动脚本

废话没有,直接上代码:

using UnityEngine;
using System.Collections;

public class SuperWalk : MonoBehaviour {

    public float speed = 10.0f;//移动速度
    public float jumpSpeed = 8.0f;//跳跃速度
    public float gravity = 20.0f;//重力

    private Vector3 moveDirection = Vector3.zero;//移动方向
    private bool grounded = false;//是否脚下有物体

    CharacterController controller;//角色控制器

    void FixedUpdate () {
        if (grounded) {//如果在地面
            //获取移动方向
            moveDirection = new Vector3(Input.GetAxis("Horizontal"),0,Input.GetAxis("Vertical"));
            moveDirection = transform.TransformDirection(moveDirection);
            moveDirection *= speed;

            //如果按了跳跃按钮
            if (Input.GetButton("Jump")) {
                moveDirection.y = jumpSpeed;
            }
        }
        moveDirection.y -= gravity * Time.deltaTime;
        //获取角色控制器
        controller = GetComponent<CharacterController>();
        //获取角色移动返回的位掩码
        CollisionFlags v = controller.Move(moveDirection * Time.deltaTime);

        //是否脚下有物体(个人理解)
        grounded = (v & CollisionFlags.CollidedBelow) != 0;

    }
}

请大神们指点
