Well, this sound ridiculous but the logic is escaping me. I have drawn my cube in OpenGL and I want to translate it to the right if any of the key on the keyboard is pressed. I know how to do this for specific keys but not for all the keys in one function? Do I have to code this for every key?

I was thinking to use glutSpecialFunc and glutKeyboardFunc? Is there any shorter way of doing this?

  • \$\begingroup\$ Reasoning for edit: OpenGL and GLUT are easy to confuse, but distinct. OpenGL is only a graphics API. GLUT is a toolkit that creates an OpenGL context inside a windowing system, and that's what's handling windows, key presses, mouse events, and such. \$\endgroup\$

Using glutSpecialFunc and glutKeyboardfunction is correct way. Whenever a key is pressed one of the function register this.

For example:

void pressKey(unsigned char key, int x, int y){
if(key=='w') close program (for example);
else movecube;

int main(int argc, char **argv) {

    glutInit(&argc, argv);

    return 1;

Whenever a key is pressed pressKey function is called and cube is moved. Anyway this wont work for some keys (ALT, CTRL, SHIFT or CAPSLOCK).
