Deoxys And One Noob:
Quick question, they did not tell me this in the tutorials, but what does %this does?

Blocki:
In what context?
%this can be everything

Ipquarx:
He means in functions, like: class::method(%this, %args0, %args1.., %argsn),
in which case %this is the instance of class that the method is being called upon.

Daenth:
%this is often used as a variable for what the function is affecting. It has no effect on the function what so ever, it's simply for convenience. You could replace it with %client and it'd be the same thing. Sounds odd to explain, but it's used for stuff like this:

--- Code: ---//Yes, it's not in a package, it's just as an example.
function GameConnection::spawnPlayer(%this) {
Parent::spawnPlayer(%this);
}

--- End code ---
%this in this example refers to the GameConnection (aka the client).

If a function is defined for an object/class, then the %this argument (whatever you name it) has to be there. If you want an argument in the function, there should be %this and then your arguments. It's how the engine works. It's not just for convenience.
