CollisionManager 类型

模块: cc 父模块: cc

一个简单的碰撞组件管理类,用于处理节点之间的碰撞组件是否产生了碰撞,并调用相应回调函数。

索引

属性(properties)
  • enabled Boolean 是否开启碰撞管理,默认为不开启
  • enabledDrawBoundingBox Boolean 是否绘制碰撞组件的包围盒,默认为不绘制
  • enabledDebugDraw Boolean 是否绘制碰撞组件的形状,默认为不绘制
方法
  • on 注册事件目标的特定事件类型回调。
  • off 删除之前用同类型,回调,目标或 useCapture 注册的事件监听器,如果只传递 type,将会删除 type 类型的所有事件监听器。
  • targetOff 在当前 EventTarget 上删除指定目标(target 参数)注册的所有事件监听器。 这个函数无法删除当前 EventTarget 的所有事件监听器,也无法删除 target 参数所注册的所有事件监听器。 这个函数只能删除 target 参数在当前 EventTarget 上注册的所有事件监听器。
  • once 注册事件目标的特定事件类型回调,回调会在第一时间被触发后删除自身。
  • dispatchEvent 分发事件到事件流中。
  • emit 该对象直接发送事件, 这种方法不会对事件传播到任何其他对象。

方法

on

注册事件目标的特定事件类型回调。

meta description
返回 Function
定义于 https:/github.com/cocos-creator/engine/blob/master/cocos2d/core/event/event-target.js:217
参数列表
  • type String A string representing the event type to listen for.
  • callback Function The callback that will be invoked when the event is dispatched.
                           The callback is ignored if it is a duplicate (the callbacks are unique).
    
  • target Object The target (this object) to invoke the callback, can be null
  • useCapture Boolean When set to true, the capture argument prevents callback
                           from being invoked when the event's eventPhase attribute value is BUBBLING_PHASE.
                           When false, callback will NOT be invoked when event's eventPhase attribute value is CAPTURING_PHASE.
                           Either way, callback will be invoked when event's eventPhase attribute value is AT_TARGET.
    
示例
node.on(cc.Node.EventType.TOUCH_END, function (event) {
    cc.log("this is callback");
}, node);
off

删除之前用同类型,回调,目标或 useCapture 注册的事件监听器,如果只传递 type,将会删除 type 类型的所有事件监听器。

参数列表
  • type String A string representing the event type being removed.
  • callback Function The callback to remove.
  • target Object The target (this object) to invoke the callback, if it's not given, only callback without target will be removed
  • useCapture Boolean Specifies whether the callback being removed was registered as a capturing callback or not.
                           If not specified, useCapture defaults to false. If a callback was registered twice,
                           one with capture and one without, each must be removed separately. Removal of a capturing callback
                           does not affect a non-capturing version of the same listener, and vice versa.
    
示例
// register touchEnd eventListener
var touchEnd = node.on(cc.Node.EventType.TOUCH_END, function (event) {
    cc.log("this is callback");
}, node);
// remove touch end event listener
node.off(cc.Node.EventType.TOUCH_END, touchEnd, node);
// remove all touch end event listeners
node.off(cc.Node.EventType.TOUCH_END);
targetOff

在当前 EventTarget 上删除指定目标(target 参数)注册的所有事件监听器。 这个函数无法删除当前 EventTarget 的所有事件监听器,也无法删除 target 参数所注册的所有事件监听器。 这个函数只能删除 target 参数在当前 EventTarget 上注册的所有事件监听器。
