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;
