Just off the top of my head, this should do what you are looking for didn’t test it and used tap instead of touch because wasn’t sure what you were really going for 
local function StartGame() local gameBG = display.newRect(0, 0, display.contentWidth, display.contentHeight) gameBG:setFillColor(1,1,1,1) gameBG.anchorX, gameBG.anchorY = 0, 0 gameBG.x, gameBG.y = 0, 0 local gameBall = nil local function SpawnBall() gameBall = display.newCircle(0,0,20,20,10) gameBall:setFillColor(0,0,1,1) gameBall.anchorX, gameBall.anchorY = 0.5, 0.5 local randomX, randomY = math.random(gameBall.width, (display.contentWidth - gameBall.width)), math.random(gameBall.height, (display.contentHeight - gameBall.height)) gameBall.x, gameBall.y = randomX, randomY function gameBall:tap( event ) timer.performWithDelay(1, function() gameBall:removeSelf() gameBall = nil SpawnBall() end, 1) return true end gameBall:addEventListener( "tap", gameBall ) end SpawnBall() end StartGame()thank you!
