I suggest you type in Max Nagl to google and on the first result there is a page called Burning Sand 1. Click that and download it (also Burning Sand 2 has the tap but I feel that it is nesisary to add)
The tap is a sources toggle. This means that when the toggle is on, then 4 different lines of liquids fall down from the top... something like this
Once liquids and gases are implemented no new elements will be added but instead a config will be worked on (a txt file) that will instruct the program, so that elements can be made and added. the mod code will be done like this
Code:
Element Nature Plant 0 255 0 0 1 1 1 0 Clear 0 File img\Plant.bmp
This is a clone of Burning Sand 1 (with some feature of BS2)
EDIT: Also in the new version that I am working on, mouse over has been removed because it does not work with a PDA as you can't hover.
