Whats this addon?

[Kirze]

well let's try thinking about this
"typed something," probably means chat
"did a self, player, client, or named brick," probably means an event

I'm guessing he means onplayertalk, or what you do with vce lastmsg

Oh wait, he already specified that.. nvm lol

onplayertalk?

onplayertalk?

Look up Variable Conditional Events
it's sort of like a very very very simplified version of scripting. But you'll still probably need to look up some tutorials on how to use it, it's more complicated then other events.
