Okay, this is probably a noob question, but seriously what are they? Like the ones that the multiplayer object type utilizes?
What is the difference between them and instance variables?
I have seen them being used in the real-time shooter template to transfer the position of the cursor in order to determine the angle of the "peer" object type (Or simply a player) and for realizing what buttons a player is pressing. Still, I feel like I'm missing something important, which I would truly appreciate my attention being brang to.
