Hi,

I have a box on screen which uses keyboard input to allow the user to move the object left,right, up, down. What i want to know it, once the user takes the box out of the window, how do i get it to reappear?

eg, user moves the box to the left, off the screen and so repears on the right hand side, etc.

also, how do you apply a background image to your window instead of just a plain colour?

Thanks!

It depends on your intention and usage of the box. You could make the box move in 3D coordinate space bounded by the viewport, or you could simply bind a key event to "recenter" the box. There are likely 10,000 other choices. Coming "back" onto the other side is a simple math problem.


glBitmap?
glBindTexture?
