If you're interested in weapons and defense systems, I can point you to tutorials. There are lots of things you can do with these, with a learning curve however you make it. If you are interested in computing methods, I could show you some of those tutorials, although those are difficult. If you are interested in art, I can't help you. If you are interested in building things that don't do anything, that's mostly self-explanatory. What are you interested in, as it applies to this game?

BTW, TPT code is at https://github.com/The-Powder-Toy/The-Powder-Toy/tree/master/src/simulation/elements

You should also check the FAQ, as it gives info as to what FP is and other things. 

There is a way to play with others here, it is called TPTMP, if you get the LUA manager, and get TPTMulti, you get to play with other people here on the powder toy (sadly. People dont really play that often anymore.)

I can help generally with the game
