【问题描述】:
我想在触摸时拖动特定的精灵。我想知道我是否可以只将事件侦听器添加到特定节点,因此在启动每个节点的特定拖动功能之前,我不必检查哪个节点被触摸。当在特定节点之外触摸时,以下代码也会“触发”。
this.directionDial = new cc.Node()
this.directionDial.graphics = this.directionDial.addComponent(cc.Graphics)
this.node.addChild(this.directionDial)
this.directionDial.graphics.lineWidth = 2;
this.directionDial.graphics.strokeColor = cc.Color.RED;
this.directionDial.graphics.circle(80, 0, 10);
this.directionDial.graphics.stroke();
var _this = this;
// Touch control
cc.eventManager.addListener({
event: cc.EventListener.TOUCH_ONE_BY_ONE,
swallowTouches: true,
onTouchBegan: function (touch, event) {
//do something
_this.forceDirection = 1;
_this.displayDirection()
return true;
}
}, this.directionDial);
