Oh… hehe wait a sec, I was trying to organize the project, and had some problems with the source files. I think your right and the problem is that it’s not using the correct files. I’m gonna see what I can do…

Ok well I’ve checked over all my code multiple times, and I included all the steps. Also I made drastic changes, and it effected the program.

@kcaz

Sorry I keep forgetting steps; I’ll be sure to use svn next time to track the changes I’ve made.

As for your error, I can’t imagine what would cause that if you’ve done Step 3 properly (which, from your expertise on the matter, I assume you have).

If I were you, the first thing I’d try is making some ridiculous changes to the b2BodyDef struct and try compile/running it (just to make sure you’re dealing with the correct copy of the file being linked/compiled).

And no, btw I’m still getting the error, and it’s not a warning, it stops the program. It says that b2BodyDef has no member named isGravitated. Im sure I’m spelling everything right.

Also I think you need to add:

if (bd->isGravitated)
{
m_flags |= e_gravitatedFlag;
}

in b2Body.cpp at the top of the file in the constructor with all the other flags.

@kcaz

Thanks for catching the typo (the missing “d”), and the function declaration (I’ve made the changes in the post accordingly). As for the message generated with “bodyDef.isGravitated = false” I don’t get that error/warning, so I’m not sure how to help you there, but it sounds to me like it’s just a warning and everything is working fine?

Also when I add:
bodyDef.isGravitated = false;

it says isGravitated is not a part of the b2BodyDef struct…which it clearly is

Oh nvm it worked. BTW you need to add the function declaration in the b2Body class, and in the actual function it should be:

return (m_flags & e_gravitatedFlag) == e_gravitatedFlag;

instead of:

eturn (m_flags & e_gravitateFlag) == e_gravitatedFlag;

Your missing a d in gravitatedFlag
