Since I first played Powder Toy a couple years back, I've really wanted to have a crack of the source code. The code was gracefully passed down to Simon who has made the source open to anyone. I'm man enough to admit I practically cried. And went head on with it.
So here it is, the first Powder Toy modification 'series' redistributed, now used as my little test build, to test elements and other mods before added to the official build.
As of Revision 9, the differences between this and the official build: - Wire - Bullet - Pipe
What has been added into the official build: - Wax (including melted) - Black/White Hole - Wind, but it was redone by Simon and called it Air - Broken Metal - Diamond
That's pretty much it. Most of it was already added into the official build.
Interesting, The bullet is neat, pipe is best to be re-named. It confuses an actual pipe with the element. All in all I'd say its good, although wire seems kinda useless. If I were to narrow down to the bare essentials, then the winner is Bullet element. Almost like the Powder Game element "Bomb"
