Rather than a mod using VC++ source, I'm starting from the ground up writing the TPT engine in Visual Basic 6. This is to correct bugs that have plauged the official VC++ version (such as things burning faster in one direction or C-4 exploding in one direction but just burning fast in another direction). Those bugs are so much based in the current code of the TPT engine that the developers are afraid to mess with the code for fear of breaking the whole thing (or at the very least to avoid reprogramming every element to work in the new engine).

I have this in the "Powder Toy Mods" section only because it is about a non-official version of TPT, not because it uses any of the original VC++ programming (typically what a mod is), because I can guaranty that not a single line of programming was copied out of the VC++ source and converted to VB6. I'm literally starting from scratch to make an improved TPT engine. I don't even have temperature in it (wood is burned by contact with fire through direct programming, not because fire is programmed to make heat or because wood is programmed to burn in response to heat). I did however carry over the 4-letter naming convention of TPT. There are 3 elements currently. METL, WOOD, FIRE. METL is a solid which doesn't respond to FIRE. WOOD is a solid which burns when in contact with FIRE, and FIRE is used to make WOOD burn. I have no gravity (or anything for that matter that is a powder or liquid which should fall in gravity). I have no air pressure/velocity. As I said, I'm working from the ground up, and have yet to program those effects in. I'm considering trying a 1x1 pixel block size for air calculations when I finally get around to it.

The current play-area size is 256x256 because this is a reasonable size for testing, and it doesn't go too slow (VB6 sucks for making 640x480 live rendered images at any reasonable frame rate).

Oh, and I'm pretty sure my numerical values for the elements are nothing like those used in TPT. So even if I could duplicate the save stamp feature (something that is still VERY FAR OFF in this program's development), I'm certain that the lack of matching numerical index values for the different elements will render my saves incompatible with the official version.

Here is a zip file that contains both the EXE file and the source code.

Box is for display only. Use the same keys as in TPT to make it work. ] = increase size. [ = decrease size.

Bug: If you draw over METL with FIRE, the METL is deleted

Actually that's how my version of TPT engine works. You don't have to erase an element before putting another element in place. Instead you just draw the element you want to replace the other element on top of the other element and it replaces it.
