oops, title is wrong... I have 2 games... same code, different graphics, my bad.

Hi.

I just started AppGameKit yesterday.

I've got some nice parallax scrolling going, a surfboard on wavy water... well, it should be wavy, but the polygon around the sprite is not exactly following the waves.

It jumps from the first wavetop on my sprite to the last wavetop, so my surfboard is in the air above all the tops that are below this line.

What am I doing wrong?

This is the code where I set the physics for the wave sprite(2 lines).

Turn on physics debugging (SetPhysicsDebuggingOn) to see the shapes used by the physics engine. This might give you a clue about the problem.

If any of your shapes are concave, then the physics engine cannot create the right polygon shape.

They are concave in places.... that explains it.

Thanks... now I just need to figure out a workaround...

Do you have any ideas?
