Animating Tile with Blitting taking up Memory I am trying to animate a specific tile in my 2d Array, using blitting. The animation consists of three different 16x16 sprites in a tilesheet. Now that works perfect with the code below. BUT it's causing memory leakage. Every second the FlashPlayer is taking up 140 kb more in memory. What part of the following code could possibly cause the leak The variable Rectangle finds where on the 2d array we should clear the pixels Fillrect follows up by setting alpha 0 at that spot before we copy in nxt Sprite Tiletype is a variable that holds what kind of tile the next tile in animation is (from tileSheet) drawTile() gets Sprite from tilesheet and copyPixels it into right position on canvas public function animateSprite() void tileGround.bitmapData.lock() if(anmArray 0 .tileType gt 42) anmArray 0 .tileType 40 frameCount 0 var rect Rectangle new Rectangle(anmArray 0 .xtile ts, anmArray 0 .ytile ts, ts, ts) tileGround.bitmapData.fillRect(rect, 0) anmArray 0 .tileType 40 frameCount drawTile(anmArray 0 .tileType, anmArray 0 .xtile, anmArray 0 .ytile) frameCount tileGround.bitmapData.unlock() public function drawTile(spriteType int, xt int, yt int) void var tileSprite Bitmap getImageFromSheet(spriteType, ts) var rec Rectangle new Rectangle(0, 0, ts, ts) var pt Point new Point(xt ts, yt ts) tileGround.bitmapData.copyPixels(tileSprite.bitmapData, rec, pt, null, null, true) public function getImageFromSheet(spriteType int, size int) Bitmap var sheetColumns int tSheet.width ts var col int spriteType sheetColumns var row int Math.floor(spriteType sheetColumns) var rec Rectangle new Rectangle(col ts, row ts, size, size) var pt Point new Point(0,0) var correctTile Bitmap new Bitmap(new BitmapData(size, size, false, 0)) correctTile.bitmapData.copyPixels(tSheet, rec, pt, null, null, true) return correctTile
