I have a tileList that I'm loading swfs into. One of my swfs has a particle system in it and every time it is loaded into the tilelist the particle system slows down. Every time the swfs are loaded I use tileList.removeAll() to clear it and then tileList.addItem() to repopulate the tileList. My guess is that this isn't actually unloading the swfs completely so they are building up in memory. What do I have to do to unload the swfs completely to prevent them from slowing down?
You have to use DataProvider property of TileList to access removeAll() method as: myTileList.dataProvider.removeAll() , refer to this document http://www.adobe.com/devnet/flash/quickstart/tilelist_component_as3/
