Do you want your title screens to look like this?
If so, go no further, because in this tutorial, I will be discussing how to get epic fire effects into your games and title screens using Axe. This is applicable to either white fire or black fire, with, or without objects in the fire.
The rules of the fire are simple. Take each pixel, move that pixel up, then also randomly erase pixels. Since each pixel on the screen has an equal probability of being erased, pixels near the top have a lower probability of being set, because the pixels would have had to travel all the way from the bottom to the top without getting erased. But thats a lot of mumbo jumbo, lets get straight to the code:
So why do we need the line command? Well because this routine needs fuel. What that means is that if you draw a sprite onto the screen while this routine is running, that sprite will catch fire automatically. If you stop drawing the sprite, it will rise and vanish like smoke. Anything you draw onto the part of the screen that is being 'flamed' will automatically catch fire, and will continue to be on fire until you stop drawing it, at which point it will vanish like smoke. Go ahead try it out!Also, some of you may want to try a black background with white smoke. The principles are exactly the same, but everything is inverted. Instead of FE (11111110), you would use 01 (00000001), and instead of using AND, you would use OR. It's that simple. :)
