dbodysetposition() memory problem

[Mr_Oizo]

Hello!

I've got a dBodyID body, and I would like to set its position, like this:

dBodySetPosition(body, x_Coord, y_Coord, 0.0);

but visual studio give me this error:
Unhandled exception at 0x0040f6f6 in traffix3D.exe: 0xC0000005: Access violation writing location 0xbaadf0a5.

0xbaadf0a5 is the memory address of body, but I don't understand, why I get this error.

Please help me!

Bye,

Zoli

Did you initialize body with dBodyCreate() ?

Thank you for your answer. That was the problem. I forgot to initialize it.
