Hello, i need to create image transformation from one to another with mouse interaction. I used tweenlite to set columns of first image to alpha=0, and after few seconds turn it back to first image. The problem is with cursor. I need to turn that column where cursor remains back to first image after a while - I need to see complete image. Hope you understand my poor english. Thank you! here is code for one column.. import com.greensock.*; import com.greensock.easing.*; import flash.events.Event; btn.addEventListener(MouseEvent.MOUSE_OVER, btnRollOver); btn.addEventListener(MouseEvent.MOUSE_OUT, btnRollOut); function btnRollOver(e:Event){TweenLite.to(btn, 0.2, {alpha:0});} function btnRollOut(e:Event){TweenLite.to(btn, 1, {alpha:1, delay:4});}
