Ok this. vars are like mostly used as timers and stuff like that...well actually a lot of other ways also. ANYWAYS, this. vars only apply to that specific NPC.
For instance:
if you made one NPC do this:
say2 #v(this.message)
and another NPC do this:
say2 #v(this.message)
they would both display different things because as I said this. vars only work for that specific NPC. Other vars apply to all npcs so if you did one NPC saying this:
say2 #v(message)
and another saying:
say2 #v(message)
they would say the same thing. Argh it's hard to explain but I hope you understand
