Unity移动端第三人称控制器_unity第三人称控制器

1.创建物体

在Hierarchy面板空白地方右键->3D Object创建一个Plane和一个Capsule

2.添加组件

鼠标单击选中Capsule

在右侧Inspector面板删除Capsule Collider碰撞体组件

添加一个Character Controller(角色控制器，自带一个碰撞体)和一个脚本ThirdPersonController(名字可以自己取)

3.编写代码

在ThirdPersonController中定义变量:

public Transform cameraTransform,cameraPole;
public float moveSpeed,cameraSpeed;
public LayerMask cameraLayers;
CharacterController character;
float cameraPitch,maxDistance;
float leftId, rightId, halfWidth;
Vector2 startPos,lookInput,moveInput;

在Start中初始化变量

void Start()
    {
   
        leftId = -1;
        rightId = -1;
        halfWidth = Screen.width / 2;

        character = GetComponent<CharacterController>();

        cameraPitch = cameraPole.localRotation.eulerAngles.x;
        maxDistance = cameraTransform.localPosition.z;
    }

创建一个函数 GetTouchInput

// 获取手指触摸的函数
void GetTouchInput()
    {
   
        //获取每一个手指的触摸信息
        foreach(Touch t in Input.touches)
        {
   
            switch (t.phase)
            {
   
                case TouchPhase.Began:
                    //点击接触
                    if (t.position.x < halfWidth && leftId == -1)
                    {
   
                        leftId = t.fingerId;
                        startPos = t.position;
                    }else if (t.position.x > halfWidth && rightId == -1)
                    {
   
                        rightId = t.fingerId;
                    }
                    break;
                case TouchPhase.Ended:
                    //手指离开
                case TouchPhase.Canceled:
                    //系统取消跟踪手指
                    if(t.fingerId == leftId)
                    {
   
                        leftId = -1;
