先上角色移動指令碼

using UnityEngine;
using System.Collections;

public class PlayerMove:MonoBehaviour
{
   private CharacterController cc;
   public float speed=4;

   void Awake()
   {
       cc=this.GetComponent<CharacterController>();
   }

   void Update()
   {
      float h=Input.GetAxis("Horizontal"
 
);
      float v=Input.GetAxis("Vertical");

      if(Mathf.Abs(h) >0.1f || Maathf.Abs(v> >0.1f)
      {
          Vector3 targetDir = new Vector3(h,0,v);
          transform.LookAt(targetDirr +transform.position);
          cc.SimpleMove(transform.forward *speed);
      }
   }
}

然後是虛擬搖桿的程式碼

using
 
 UnityEngine;
using System.Collections;

public class Joystick:MonoBehaviour
{
    private bool isPress =false;
    private Transform button;
    public static float h=0;
    public static float v=0;
    void Awake()
    {
        button=transform.Find("Button");
    ｝
    //當按鍵按鈕的時候觸發
    void OnPress(bool
 
 isPress)
    {
        this.isPress=isPress;
        if(isPress == false)
        button.localPosition=Vector3.zero;
        v=0;
        h=0;
    }
    void Update()
    {
        if(isPress)
        {
            Vector2 touchPos=UICamera.lastTouchPosition;
            touchPos -=new Vector2(91,91);
            float distance =Vector2.Distance(Vector2.zero,touchPos);
            if(distance >73)
            {
                touchPos=touchPos.normalized *73;
                button.localPosition =touchPos;
            }
            else
            {
                button.localPositon =touchPos;
            }
            h=touchPos.x /73;
            v=touchPos.y /73;
        }
    }
｝

最後是鍵盤和虛擬搖桿的結合
其實很簡單 只需要修改這一段程式碼就行了

void Update()
   {
      float h=Input.GetAxis("Horizontal");
      float v=Input.GetAxis("Vertical");

      if(Mathf.Abs(h) >0.1f || Maathf.Abs(v> >0.1f)
      {
          Vector3 targetDir = new Vector3(h,0,v);
          transform.LookAt(targetDirr +transform.position);
          cc.SimpleMove(transform.forward *speed);
      }
   }

修改成

void Update()
   {
      float h=Input.GetAxis("Horizontal");
      float v=Input.GetAxis("Vertical");

      if(Joystick.h != 0 || Joystick.v !=0)
      {
          h=Joystick.h;
          v=Joystick.v;
      } 

      if(Mathf.Abs(h) >0.1f || Maathf.Abs(v> >0.1f)
      {
          Vector3 targetDir = new Vector3(h,0,v);
          transform.LookAt(targetDirr +transform.position);
          cc.SimpleMove(transform.forward *speed);
      }
   }
