Hey, I am making an Asteriods clone, incase you don't know what that is, here http://www.getfrosty.com/Games/asteroids/asteroids.htm , and I am fairly new at lua. I am wondering how do I make the asteriods go across the screen at random times in random places and still going towards the middle of the screen to the player. I have the rest of the coding pretty much done and this will help me a ton, thanks!

look in the wiki for os.randomseed

math.random(number) for random entry points
manage all the rocks in a drawing function,
i did that and it works good.

so you spawn new rocks in a certain amount of time.

(math.mod(gametimer,refreshtime)==0 then bla)

only blit them if they are onscreen (x,y)

if X>playerX x=x-speed etc. for Y the same
