這篇文章主要介紹了Unity EasyTouch搖桿插件使用,這套插件還支持雙指縮放，滑動(dòng)，手指畫圈，點(diǎn)擊，多指觸碰，拖拽等，通過示例代碼給大家介紹的非常詳細(xì)，需要的朋友可以參考下

EasyTouch搖桿插件使用，先給大家展示下效果圖：

Demo展示

雙指縮放在電腦端無法掩飾，豎屏將就看看吧；

插件名叫EasyTouch，有需要給我留言，不想開倉庫傳了；

創(chuàng)建搖桿點(diǎn)這里：

初始化

On_JoystickMove這個(gè)回調(diào)是用來控制移動(dòng)的；分兩個(gè)方向，x和y軸；

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

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

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

自定義On_JoystickMove

我的搖桿物體名稱叫做MoveControl；

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

    float PositionX = move.joystickAxis.x; //獲取搖桿偏移搖桿中心的x坐標(biāo)
    float PositionY = move.joystickAxis.y; //獲取搖桿偏移搖桿中心的y坐標(biāo)

    Vector2 value = move.joystickValue;
    if (PositionY != 0 || PositionX != 0)
    {
        //設(shè)置控制角色或物體方塊的朝向（當(dāng)前坐標(biāo)+搖桿偏移量）
        //transform.LookAt(new Vector3(transform.position.x + PositionX, transform.position.y,transform.position.z + PositionY));
        //移動(dòng)角色或物體的位置（按其所朝向的位置移動(dòng)）
        Vector3 dir = new Vector3(PositionX, PositionY, 0);
        
        transform.Translate(dir * Time.deltaTime * speed);
    }
}

這兩個(gè)物體控制搖桿，EasyTouch一定不能刪除；

手勢功能

這套插件還支持雙指縮放，滑動(dòng)，手指畫圈，點(diǎn)擊，多指觸碰，拖拽等；

具體api看注釋：
