well I am able to move a sprite from the center of the screen to the right. it however moves too quickly, I want it to move one sprite width to another, I also want to move slowly. I want it to move like in space invaders.

I am using fixed time step and using move_right++ to move the sprite but it moves too fast. also I want it to move one sprite width at a time. maybe I should use a variable time step.

how do I determine my tick rate?

well I have 8 pages of code and I think I have already posted the drawing portion of my game.

	glColor3f(1.0f, 1.0f, 1.0f);
	glBegin(GL_POLYGON);
	glTexCoord2f(0.0f, 0.0f);
	glVertex3f(x, y, 0.0f);
	glTexCoord2f(1.0f, 0.0f);
	glVertex3f(x, y-1.0f, 0.0f);
	glTexCoord2f(1.0f, 1.0f);
	glVertex3f(x+1.0f, y-1.0f, 0.0f);
	glTexCoord2f(0.0f, 1.0f);
