Well the whole point of it is to hide doodads for a player in a region. The problem is getting the agent attached and removed for the hide messages to be sent. I was thinking that perhaps I should just create the agent for every doodad on the map and just send the hide message to it and not destroy it but that's basically doubling the number of doodad actors.

Renee2islga AuthorThis tutorial is for show/hide specified actors. Actor Regions, is a bit different. I would have it done in my future tutorial, actually it's much easier. But Im quite busy recently.
Actually the "Phasing Tech" series will have three tutorials. This artcle is just the first one, for beginner. The second one the true "Phasing Tech", which would have a universal custom function "Send Actor Message To Actor For Player Group", allows you send ANY message asyncly, and doesn't need to modify the agent actor. The third one would be send message to a actor region asyncly, and it is the most easy one.
