There are several ways to approach this. Perhaps the best one is to put an Runtime “enterFrame” listener on the object that gets called very frame update (30 or 60 times a second). And you can put in whatever tests you need to and reactions to positions.

local box = display.newRect( 100, 100, 50, 50 ) function box:enterFrame() if self.x \> display.contentWidth then -- box is off screen print("off screen") Runtime:removeEventListener( "enterFrame", self ) end end Runtime:addEventListener( "enterFrame", box ) transition.to( box, { time=1000, x = display.contentWidth + 100 } )
