handle= variable holding the image's handle
x=starting x location of the tile; assumed 0 y=starting y location of the tile; assumed 0 frames=the frame of the image to tile; optional with imagestrip |
| If you want to make a starfield or other easy tiled background, this is YOUR command. All you have to do is specify the image handle (an image loaded with the LoadImage or LoadAnimImage command). Optionally, you can specify a starting x and y location, as well as an optional frame. You can milk some serious parallax effects with a simple imagestrip with a couple of various starfields and the TileImage command. |
