How to make a brick that teams you and teleports you?

Hello everyone,

So, me and my friend decided we want to learn how to develop a game. Our biggest obstacle right now is scripting.

Long story short, we need a brick that could team you at the same time and teleport you into the arena.

It would be GREATLY appreciated if you'd tell what each line does, as it helps to understand and learn Lua easier.

If that's not possible, a brick that would do one of the things (teleport from point A to point B or team upon being touched) would also help.

If more info is needed, please say. Note, that we don't know much about Lua at all.
