what's wrong

It compiles and shows the rotating pyramid but the 'w' and 's' keys don't do anything (was takken from movement example)

This line is wrong:

Code: Select all

  IrrlichtDevice *device =
       createDevice(video::EDT_OPENGL, core::dimension2d<s32>(800, 600), 16, false);

You should specify your event receiver as the 6th argument, like this:

Code: Select all

  IrrlichtDevice *device =
       createDevice(video::EDT_OPENGL, core::dimension2d<s32>(800, 600), 16, false, flase, &MyEventReceiver);

oh... and what's that block of code after the (first) "return 0;" in your main() function?
