function shooting(player,mousePosition)
	local character = player.Character
	local filter = {character, game.Workspace.AllBullets}
	if cooldown then
		cooldown = false
		local hitPart = createRay(tool,character,mousePosition,filter)
		gun.Shoot:Play()
		flash.Transparency = createFlash(0)
		delay(flashtime,function()
			flash.Transparency = createFlash(1)
		end)
		delay(firerate,function()
			cooldown = true
		end)
		return hitPart
	end
end

I don't quite understand how to properly use coroutines multiple times because after one use they're dead. I ended up using delay and my code works, but I heard delayed isn't that reliable and shouldn't be used? The purpose of using delay here is so that return hitPart can be sent back right away and not after a long wait().
