I wish to use the older (v1.4.1) Box2D wrapper for Dark Basic Professional under Dark Basic Classic. This code runs for me, but the DLL returns 0 for both the X and Y position of the box. The example is largely based on the examples in the examples thread.

Don't forget to put physicsplugin.dll into the project directory!



Is there something I need to set up in DBC, or is it just incompatible and that's the end?

And it still boots quicker than any other laptop I've seen.

What about the other values returned, are they non-zero?
If they are non-zero, it might be because GetBodyX/Y returns floats, which in DBP are passed by casting to DWORDs because floats are returned through a different method, and so wouldn't work otherwise. In DBC, this may be different.

I get nonsense numbers returned by the object and world constructor functions. I did wonder if the datatypes were incompatible. I expected the debug function not to work, as it probably does some framebuffer access or something. Angle, velocity and position all return zero. I should probably give up trying to run this DLL under Classic.

Thanks for your input.

What do you mean 'nonsense' numbers? They return pointers, so they will not be 1 or 2 or anything. If they are non-zero it means that the functions are working!

Also, what happens if you try version 2 under DBC? I recently created all the help files too (well maybe I did cheat a bit, but who cares!)

edit:
btw, I DO want your MSN

If V2 doesn't work, and I can find an example for returning floats to DBC, I would consider making a DBC compatible version.
