物理碰撞监听的开关enabledContactListener无法正常起效@官方，应该是BUG

Creator 3.x
#1

在做碰撞监听的时候，发现enabledContactListener=false和=true无法正常开关碰撞监听@官方 这应该是bug
想实现的效果：
拖拽移动一个物体时，关闭该物体的碰撞监听，释放手指时，打开监听，代码如下
实际的效果：
碰撞监听一直存在，enabledContactListener无法起到开关的作用

    else{

        PhysicsSystem2D.instance.debugDrawFlags=EPhysics2DDrawFlags.None;

已经通过另外的方式来实现拖拽的过程中关闭碰撞监测，松开后打开监测
用CircleCollider2D 组件的enable属性=false 或=true来实现开关，代码如下

this.node.on(Node.EventType.TOUCH_MOVE,function(event){

        const target = event.target as Node;

        var c=target.getComponents(CircleCollider2D);

        c[0].enabled=false;

        c[1].enabled=false;

        c[2].enabled=false;

        c[3].enabled=false;

        //let flagCollision=target.getComponent(RigidBody2D).enabledContactListener;

        //flagCollision=false;

        //console.log("flagCollision="+flagCollision);

        var moveXY=new Vec3;

        var toXY=new Vec3;

        moveXY.x=event.getDeltaX();//获取鼠标距离上一次事件移动的X距离

        moveXY.y=event.getDeltaY();//获取鼠标距离上一次事件移动的Y距离

        toXY.x=target.position.x + moveXY.x/1.5;

        toXY.y=target.position.y + moveXY.y/1.8;

        target.setPosition(toXY);

    })

   

    this.node.on(Node.EventType.TOUCH_END,function(event){

        //const target = event.target as Node;

        //let flagCollision=target.getComponent(RigidBody2D).enabledContactListener;

        //flagCollision=true;

        c[0].enabled=true;

        c[1].enabled=true;

        c[2].enabled=true;

        c[3].enabled=true;

    })
