I've seen some blocks in pyspades that function as switches and also being able to place/destroy large squares at a time. How can I do this? I already know how to host a pyspades server.

Okay, I guess I really need to write up those platform docs. In the meanwhile, you could check out the SuperCool build server. They're like the official platform training academy, and they can put you in the right track if you ask nicely.
