unity3d自己写角色移动脚本

废话没有,直接上代码:
 1 using UnityEngine;
 2 using System.Collections;
 3 
 4 public class SuperWalk : MonoBehaviour {
 5 
 6     public float speed = 10.0f;//移动速度
 7     public float jumpSpeed = 8.0f;//跳跃速度
 8     public float gravity = 20.0f;//重力
 9 
10     private Vector3 moveDirection = Vector3.zero;//移动方向
11     private bool grounded = false;//是否脚下有物体
12 
13     CharacterController controller;//角色控制器
14 
15     void FixedUpdate () {
16         if (grounded) {//如果在地面
17             //获取移动方向
18             moveDirection = new Vector3(Input.GetAxis("Horizontal"),0,Input.GetAxis("Vertical"));
19             moveDirection = transform.TransformDirection(moveDirection);
20             moveDirection *= speed;
21 
22             //如果按了跳跃按钮
23             if (Input.GetButton("Jump")) {
24                 moveDirection.y = jumpSpeed;
25             }
26         }
27         moveDirection.y -= gravity * Time.deltaTime;
28         //获取角色控制器
29         controller = GetComponent<CharacterController>();
30         //获取角色移动返回的位掩码
31         CollisionFlags v = controller.Move(moveDirection * Time.deltaTime);
32 
33         //是否脚下有物体(个人理解)
34         grounded = (v & CollisionFlags.CollidedBelow) != 0;
35 
36     }
37 }
控制角色移动脚本
请大神们指点
