Simple Chipmunk Physics

[Ingemar]

Hmmm, demo11 from ZenGL maybe can help you with initialization of Chipmunk, and drawing... anyway it will be easy to translate into other engine/API As soon as I resolve a problem with translated Chipmunk demos into Pascal for Linux(using pure OpenGL and glut), I will add them to my Chipmunk Pascal binding - chipmunk-pascal.

A bit incomplete though, with libraries for Windows and Linux but not Mac. Also, a simple demo would be helpful.

(And I am saying that just because FPC interfaces to Chipmunk Physics sounds really, really useful so I really want to try it!)

Mmm? And what is libchipmunk.5.3.2.dylib in bin directory do you think? This library, and simple demo, you can find with ZenGL(demo11). Unfortunately I have no time to finish that chipmunk demos, about which I said before.

Maybe so but I was referring to what I found at the chipmunk-pascal link.

In chipmunk-pascal svn you can find libchipmunk.dylib too.

Two days ago I took another look at the Chipmunk physics. Well, I made some progress, as you can see here (using my SDL based egslengine):



However, I have a problem on Windows 32bit with the static linking (FPC 2.6.0) using the latest headers by Andru. Issue is

Target OS: Win32 for i386
Compiling physictest.pas
Linking physictest.exe
physictest.pas(124,1) Error: Undefined symbol: _cpInitChipmunk
physictest.pas(124,1) Error: Undefined symbol: _cpMomentForCircle
physictest.pas(124,1) Fatal: There were 2 errors compiling module, stopping
Fatal: Compilation aborted

Any idea?

Are you sure about latest? And if so - did you change path to object files? Structure of lib directory was changed, so in Lazarus you should specify something like this now - lib/$(TargetCPU)-$(TargetOS), or choose path for platform manually(in your case this is i386-win32).

Oh, sorry, it was my fault. It works now. Thank you.
