    help with some game logics

    Hi, I have done this function draw_random_tank() in OpenGL, this function generate random numbers and place the objects on my landscape based on the random numbers generated. My question is this, because I have some keyboard function which will call glutPostRedisplay(), every time I press the key, it invokes the glutPostRedisplay(), therefore my draw_random_tank gets called, and their position changes every time a key event is pressed. How can I fix this? thanks(sorry, this is quite a long post).

    Placing the tank on the terrain at random sounds like it should only be done in the initialization stage of your game...not in the rendering loop and/or main game loop.

    Put this code outside of the game loop to 'setup' the game and you won't experience this problem.
