I am a beginner coder. I watched the tutorial in integrating AdColony with Cocos2d-x, and came across something I don’t understand.

After the user watches a video ad, this callback function is called in IOSResults.mm.

+( void )videoWasViewedAdcolony:( BOOL )result

{

    // CPP code here

}

Also, the adcolony ad was called from HelloWorldScene.cpp.

AdColony::showVideoAC(true, true);

 How can I connect these two files: IOSResults.mm ↔ HelloWorldScene.cpp?

I want to do some action with the variables in HelloWorldScene.cpp from IOSResults.mm.

If you can tell me what to study for to do such thing, I can look it up in google( if it’s too complicated to be explained here. ).

Thank you.
