Unity EasyTouch摇杆插件使用示例详解

EasyTouch摇杆插件使用，先给大家展示下效果图：

Demo展示

双指缩放在电脑端无法掩饰，竖屏将就看看吧；

插件名叫EasyTouch，有需要给我留言，不想开仓库传了；

创建摇杆点这里：

初始化

On_JoystickMove这个回调是用来控制移动的；分两个方向，x和y轴；

void OnEnable()
{
    EasyJoystick.On_JoystickMove += OnJoystickMove;
}

private void OnDisable()
{
    EasyJoystick.On_JoystickMove -= OnJoystickMove;
}

private void OnDestroy()
{
    EasyJoystick.On_JoystickMove -= OnJoystickMove;
}

自定义On_JoystickMove

我的摇杆物体名称叫做MoveControl；

void OnJoystickMove(MovingJoystick move)
{
    if (move.joystickName != "MoveControl")
    {
        return;
    }

    float PositionX = move.joystickAxis.x; //获取摇杆偏移摇杆中心的x坐标
    float PositionY = move.joystickAxis.y; //获取摇杆偏移摇杆中心的y坐标

    Vector2 value = move.joystickValue;
    if (PositionY != 0 || PositionX != 0)
    {
        //设置控制角色或物体方块的朝向（当前坐标+摇杆偏移量）
        //transform.LookAt(new Vector3(transform.position.x + PositionX, transform.position.y,transform.position.z + PositionY));
        //移动角色或物体的位置（按其所朝向的位置移动）
        Vector3 dir = new Vector3(PositionX, PositionY, 0);

        transform.Translate(dir * Time.deltaTime * speed);
    }
}

这两个物体控制摇杆，EasyTouch一定不能删除；

手势功能

这套插件还支持双指缩放，滑动，手指画圈，点击，多指触碰，拖拽等；

具体api看注释：

public class Zoom : MonoBehaviour
{
    bool isStart = false;
    public Button BtnReset;
    public Button BtnLoadScene;
    public Text log;
    void OnEnable() {
        EasyTouch.On_Swipe += On_Swipe;
        EasyTouch.On_Drag += On_Drag;
        EasyTouch.On_Swipe2Fingers += On_Swipe2Fingers;
        EasyTouch.On_PinchEnd += On_PinchEnd;
        EasyTouch.On_PinchIn += On_PinchIn;
        EasyTouch.On_PinchOut += On_PinchOut;
        BtnReset.onClick.AddListener(ResetScene);
        BtnLoadScene.onClick.AddListener(OnLoadScene);
    }  

    void OnDisable() {
        EasyTouch.On_Swipe -= On_Swipe;
        EasyTouch.On_Drag -= On_Drag;
        EasyTouch.On_Swipe2Fingers -= On_Swipe2Fingers;
        EasyTouch.On_PinchEnd -= On_PinchEnd;
        EasyTouch.On_PinchIn -= On_PinchIn;
        EasyTouch.On_PinchOut -= On_PinchOut;
        BtnReset.onClick.RemoveListener(ResetScene);
    }  

    void OnDestroy() {
        EasyTouch.On_Swipe -= On_Swipe;
        EasyTouch.On_Drag -= On_Drag;
        EasyTouch.On_Swipe2Fingers -= On_Swipe2Fingers;
        EasyTouch.On_PinchEnd -= On_PinchEnd;
        EasyTouch.On_PinchIn -= On_PinchIn;
        EasyTouch.On_PinchOut -= On_PinchOut;
        BtnReset.onClick.RemoveListener(ResetScene);
    }

        }
    }
