Code:

---

function beam_weapons
{
	while ((mouse_left == 1))
	{
		if(player.phaser <= 0) { break; }
		phaser_decreasing = on;
		player.phaser -= 3*time_step;
		snd_play (beam_wav, 50, 0);
		wait(1);
	}
	phaser_decreasing = off;
}

could you post the weapon code? oops didn't see logans post. oh and all that will do, atleast i think, is stop the energy decreasing it won't stop it from shooting. you should have a check in your shooting code if energy is <0 if so don't shoot.

spot on, thanks guys.
