Here the emscripten page : https://cromdesi.home.xs4all.nl/emscripten/bushfire/Untitled1.html Here a youtube video of it : https://youtu.be/VOVi-KdhQ5c I found this method online years ago. What it does is find a position on the map and see if it can burn a position next near it. So creating a surface. Here I made it so it makes different style maps each time. I made it so it goes slowly from empty to a filled screen. Would also be changeable to screen dissolve. Press mouse (tap) on the map to create new map. Code is monkey 2. #Import "<std>" #Import "<mojo>" Using std.. Using mojo..
