I'm trying to make camera control in OpenGL/glut.

I works fine with the arrow keys.

But i won't work with the mouse because in only updates when in press a moue button.

Now i my question.
Is there a way to get the mouse x, y each time the mouse moves instead of each time there is a button pressed or released?

I use now: glutMotionFunc(MouseMove);

code of MouseMove


void MouseMove(int x, int y){
printf("MouseX = %d\n", x);
Player.HandleMouseMove(x);

glutWarpPointer(SCREEN_WIDTH/2, SCREEN_HEIGHT/2);

}

glutMotionFunc indeed only triggers when you move the mouse with a button pressed. You want glutPassiveMotionFunc instead, which triggers at any time you move the mouse as long as the window is in focus. I am not sure if it triggers only when no buttons are pressed, or always triggering on movement, so you may have to use both.

That was the problem thx
