Problem with Box2d-template project from Cocos2d v0.8.2

I am having some troubles using Box2d on a project I am playing around with.

I have created the project using the Box2d-template provided with the latest release of cocos2d.

The HelloWorld-scene works great. I then imported a scene from another project of mine (GameScene.h and GameScene.m). Imported all resources and everything to make that scene work without Box2d, when that was done I tried adding the Box2d.h and the other GLExxx.h included, the same headers as in HelloWorld-scene, to the header (GameScene.h).

As soon as I try to compile this I get a lot of errors (over 800). I have read on the forum and found some solutions. Tried changing the GameScene.m to GameScene.mm, didn't do it.

Is there something I have missed? or is there something more I have to do to get my GameScene to recognize the box2d framework? I have compared my scene with HelloWorld-scene, but can't see what the problem is.

probably a silly question, but is the older project using the same version of box2d thats currently shipping with cocos2d?

I am not using Box2d in the older project, I just lifted one scene just for the purpose of implementing it in the Box2d-template project.

Hi degborta,

Try deleting the new imported files. Make sure you save as .mm and do a "Clean All Targets" and try to compile again. That worked for me.

Thanks,

Kenny

I have the same problem since 0.8.2. Sometimes it will compile with no error and and I compile the second time even with no changes I get thousand of warnings from Box2D. Nothing I've tried works.

I had a similar problem. I'm pretty new to all this stuff .. so I might not be very correct. But here is what worked for me.

Apparently, some of the methods for creating box2d bodies with shapeDef etc are diff. from the ones in the older release. You can see the diff. by comparing those side by side. (From old and new box2d sources - in b2shape or b2polygonShape etc)

What you can do is review Box2D Testbed code with the newer release to find out those changes. Then decide if its easy for you to do those changes to your source or stick to the older version.

Hope this helps!
