Question

I’m trying to modify my bitmap to change their pixels to a random color. This is the way I do it (I’m using the FlashPunk library):

private var _v:Point = new Point;
private var _speed:Point = new Point(200, 200);
private var _bmpData:BitmapData = new BitmapData(24, 24, false, 0x000000)
private var _bmpImage:Image = new Image(_bmpData);

public function Player(p:Point) 
{
    graphic = _bmpImage;
    x = p.x;
    y = p.y;
}

override public function update():void
{
    updateMovement();
    updateCollision();

    super.update();
}

override public function render():void 
{
    _bmpData.lock();
    for (var j:int = 0; j < _bmpData.height; j++) {
        for (var i:int = 0; i < _bmpData.width; i++) {
            _bmpData.setPixel(i, j, FP.rand(0xffffff));
        }
    }
    _bmpData.unlock();

    graphic = new Image(_bmpData);
    super.render();
}

So ok, the function that does this is render(), but in the line

graphic = new Image(_bmpData);

I get new memory for graphic, and this translate into a memory leak in the game. Here is an image of this:

And as you can see, the MEM: part is constantly increasing :/

Anyone knows another way to do this?

Answer 1

At the end I only had to replace

graphic = new Image(_bmpData);

for

_bmpImage.updateBuffer(); and now it works fine 🙂

Here is the doc for that function
