Since Cocos2d-x 3.0, we have refactored the event dispatching system.
cc.registerTargetedDelegate and all layer's event functions have been deprecated. So you should migrate your implementation with the new event dispatching system.
If you want to upgrade your usb project with the newest Cocos2d engine, you should download Cocos2d-JS which include Cocos2d-x 3.0 rc0 and Cocos2d-html5 3.0 alpha: Download link
In the download package, you can find the test cases shared by html5 and jsb. The test case jsb project can be found in the folder
build, and you will find tests which shows you how to use the new event system at
Event Manager Test. And the sub test
PauseResumeTargetTest shows exactly what you want to do.
Tell us if the new event system solve your problem.
