LevelHelper 和 Box2D Collions：如何获得“标签”？

Question

I have successfully made a very simple LevelHelper/Box2D/Cocos2D project. I am now trying to register a collision as described in the documentation here .

I used the example code as follows:

[lh registerBeginOrEndColisionCallbackBetweenTagA:COIN
                                          andTagB:MARIO
                                       idListener:self
                                      selListener:@selector(beginEndCollisionBetweenMarioAndCoin:)];

My Question is this: how do I get the tag? Am I correct in setting it in LevelHelper in the "General Properties" pane? (below)

In LevelHelper's Custom Properties window the "Tag Value" for "CHARACTER_TAG" is 1, but if I try and put this into the above code instead of "MARIO" XCode gets upset because it "cannot initialize a parameter of type 'enum LevelHelper_TAG' with an rvalue of type 'int' " (fair enough).

Thank you!

I've figured it out!

After setting the tag to CHARACTER_TAG in LevelHelper, I needed to regenerate my code with File\\Generate Code\\Cocos2D with Box2D. Then I could simply type CHARACTER_TAG in place of MARIO as seen in my question!

I hope this helps someone!
