Objects not converging at center of screen

I placed the following code inside a ButtonListener, but the two objects I have being spawned converge with each other instead of in the center of the screen. I basically just want both matching objects to meet at the center of the screen regardless of which of the two you tap on. I’m probably missing something really simple. Any idea what though?

--ButtonListener for Matching Group local buttonListener = function( event ) &nbsp; &nbsp; &nbsp; if event.numTaps == 1 then &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; playSFX(audiomatchsound) &nbsp; &nbsp; &nbsp; &nbsp; local group = matchgroup &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; local oldVector = group.rotation &nbsp; &nbsp; &nbsp; &nbsp; local newVector = 0 &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; --make matching objects explode in center of screen using sparkle &nbsp; &nbsp; &nbsp; &nbsp; local px = centerX &nbsp; &nbsp; &nbsp; &nbsp; local py = centerY&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; local function sparkleExplode(Obj) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; display.remove(Obj) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Obj = nil &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; transition.cancel ( group.trans ) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; --How about a little poof to boot &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; local pop = display.newCircle(levelGroup, px, py, math.random(1,2)) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; local function DestroyPop(Obj) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; display.remove(Obj) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Obj = nil &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; end &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; transition.to(pop, {time=400, alpha = 0, onComplete=DestroyPop}) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; --end of extra poof code &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ExplodeStyleEmitter(px, py) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; timer.performWithDelay(1000, placeitems, 1) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if matchgroup ~= nil then &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; matchgroup:removeSelf(1) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; matchgroup = nil &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; end &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if nonMatchImageHolder ~= nil then &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; --Remove display table of nonmatch items &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; for key,obj in pairs(nonMatchImageHolder) do &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; obj:removeSelf() &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; obj = nil &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; end &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; end &nbsp; &nbsp; &nbsp; &nbsp; end &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; --send object to center of screen &nbsp; &nbsp; &nbsp; &nbsp; group:toFront() &nbsp; &nbsp; &nbsp; &nbsp; physics.pause() &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; local px = display.contentWidth/2 &nbsp; &nbsp; &nbsp; &nbsp; local py = display.contentHeight/2 &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; item1.trans = transition.to( item1, {time=500, x = px, y = py, onComplete=sparkleExplode} ) &nbsp; &nbsp; &nbsp; &nbsp; item2.trans = transition.to( item2, {time=500, x = px, y = py, onComplete=sparkleExplode} ) &nbsp; &nbsp; &nbsp; &nbsp; --while moving to center, rotate matching objects back to upright position &nbsp; &nbsp; &nbsp; &nbsp; if oldVector ~= newVector then &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; transition.to( item1, {time=500, rotation = 0} ) &nbsp; &nbsp; &nbsp; &nbsp; end &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; addPointToPlayer(1) &nbsp; &nbsp; end end
