Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Mods What does _Event at the end of functions do?

Some of the functions end with (STRING)_Event). For instance:

CharacterMoveToItem(_CHARACTER,_ITEM,1,_EVENT);

I assumed it could be used to start an event. After using the function above I tried using

IF
GlobalEventSet("EVENT")
THEN
...

But the THEN part didn't fire.
