ok, i have a question. Can anyone tell me how the setInterval command works?

i want it so that after you fire a laser from your spaceship, it takes 0.5 seconds to fire another.

setInterval(_function,time in ms_);

It calls the funtion every time the timer reaches the time in ms. It resets once it calls it.

setInterval(fireLaser,500);

Cool,
