Question

I would like to iterate through an array that covers every pixel on my screen. i.e:

        for (int y = 598; y > 0; y--)
        {
            for (int x = 798; x > 0; x--)
            {
                if (grains[x][y])
                {
                    spriteBatch.Draw(Grain, new Vector2(x,y), Color.White);
                }
            }
        }

…my texture is a 1×1 pixel image that is drawn to the screen when the array value is true. It runs decent — but there is definitely lag the more screen I cover. Is there a better way to accomplish what I am trying to achieve?

Answer 1

Instead of using X x Y individual sprites, create a single image, and set the pixels appropriately. Then just render the entire image as a texture on a single sprite.

The jagged array is most likely not the problem – rather the nearly half-million sprites.
