I want to create an object that is moving in a random direction when it hits the stage, any ideas? Thanks!

Hey!
So you can do this easily I think…!
I’d say just do this…
and you can replace ball with your object!
and tweak anything else

[code]
local movespeed= math.random(-50,50)
local ball= display.newCircle(10,10,25)

function ball:enterFrame(event)
ball.x= ball.x+movespeed

end

Runtime:addEventListener(“enterFrame”,ball) [import]uid: 95032 topic_id: 16474 reply_id: 61461[/import]

That’s cool! Thanks a bunch. So the Runtime command is used to initiate a function when the program starts? [import]uid: 96383 topic_id: 16474 reply_id: 61468[/import]

Runtime just means “every frame” pretty much… I’m not sure what you mean by that initiating… but all you want is know that Runtime:addEventListener(“EnterFrame(which is every frame)”,and your object which has That EnterFrame… You an do ball.y also!

If you want to “initiate” something when the app starts, you do it like so;
[lua]function()[/lua]

Obviously using the function name rather than “function” :slight_smile: [import]uid: 52491 topic_id: 16474 reply_id: 61636[/import]
