CollisionManager Class

Module: cc

A simple collision manager class. It will calculate whether the collider collides other colliders, if collides then call the callbacks.

Returns Function
Defined in cocos2d/core/event/event-target.js:218
Parameters
  • 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.
    
Examples
node.on(cc.Node.EventType.TOUCH_END, function (event) {
    cc.log("this is callback");
}, node);
off

Removes the listeners previously registered with the same type, callback, target and or useCapture, if only type is passed as parameter, all listeners registered with that type will be removed.

meta description
Defined in cocos2d/core/event/event-target.js:275
Parameters
  • 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.
    
Examples
// 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

Removes all callbacks previously registered with the same target (passed as parameter). This is not for removing all listeners in the current event target, and this is not for removing all listeners the target parameter have registered. It's only for removing all listeners (callback and target couple) registered on the current event target by the target parameter.

Parameters
  • target Object The target to be searched for all related listeners
once

Register an callback of a specific event type on the EventTarget, the callback will remove itself after the first time it is triggered.

Parameters
  • 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.
    
Examples
node.once(cc.Node.EventType.TOUCH_END, function (event) {
    cc.log("this is callback");
}, node);
dispatchEvent

Dispatches an event into the event flow. The event target is the EventTarget object upon which the dispatchEvent() method is called.

meta description
Defined in cocos2d/core/event/event-target.js:397
Parameters
  • event Event The Event object that is dispatched into the event flow
emit

Send an event to this object directly, this method will not propagate the event to any other objects. The event will be created from the supplied message, you can get the "detail" argument from event.detail.

  • detail Any whatever argument the message needs
