I'm using using them for many reasons, but I only know a few of them. Yet, only the veterans of the editor would know.
When I create an actor within the actor, I can change its scale, tint, etc from the very same actor that creates it, and for that I use the Target box, and type the ID name of the Actor that was created. If I want to modify the actor's portrait and send it events, I type ::PortraitGameSelf
This ::PortraitGameSelf is a code. I want those codes. What is the one for an attach model, or death actor, or build actor. How can I know those target codes that are known by heart or unknown?
