self notifyOnPlayerCommand( "button name", "button function" );
Example:
self notifyOnPlayerCommand( "button_back", "togglescores" );

This names the togglescores button (the back button) "button_back"

self waittill("button name");

The button name is whatever you named the funcition in the code above

So the back button would be

self waittill("button_back");
{
// code you want to happen when back button is pressed
}

you can change these numbers to whatever you want, but these stats look pretty legit.

If the dvar is infectable (some arent)
self setClientDvar( "dvar", value );

If it is non-infectable (will only apply to that current game)
self setDvar( "dvar", value );

There are lists of dvars all over the internet. Some are larger than others. Here is one:[You must be registered and logged in to see this link.]
