Question

OK so take a look at this vid (it’s 3 seconds long..) showing the problem:

http://www.screenr.com/VbV

See how the images flicker when you first enter the room?

Here’s how I have the images set up (they are pulled from tiles folder in the .jar file)

            for (int i = 0; i < 522; i++) {
tiles[i] = tk.getImage(this.getClass().getResource(String.format("tiles/t%d.png", i)));

                  }

and here’s how they are painting on:

        for (row = 0; row < board.length; row++) {
            for (col = 0; col < board[row].length; col++) {
                  int index = board[row][col];
                  g.drawImage(tiles[index], 32 * col, 32 * row, this);

            }
      } 

How do I stop the flicker…

Answer 1

The Toolkit.getImage(URL) method is asynchronous and 522 images might take a ‘few moments’ to load. Either add them to a MediaTracker or use ImageIO.read(URL) instead.
