Thanks a lot.

You could use transition.to() with an onComplete listener for another transition.to() to loop the movement.

See here; http://developer.anscamobile.com/reference/index/transitionto

If you struggle let me know, I can try to write you a little example :slight_smile:

OK, this could be optimized and shortened down but should work well and be very easy to follow.

[lua]display.setStatusBar (display.HiddenStatusBar)

local trans1
local trans2
local trans3
local trans4

local box = display.newRect( 50, 50, 40, 40 )

trans1 = function()
transition.to(box, {time=1000, x=270, onComplete=trans2})
end

trans2 = function()
transition.to(box, {time=2000, y=430, onComplete=trans3})
end

trans3 = function()
transition.to(box, {time=1000, x=50, onComplete=trans4})
end

trans4 = function()
transition.to(box, {time=2000, y=50, onComplete=trans1})
end

trans1()[/lua]
