Hey, those trigger actors are from Epic’s Content Examples project.

To answer your question: The array is populated in the level, you need to click on a trigger actor in the world outliner and look at the array in the details panel to see which actors it is capable of influencing (via the Call Trigger Actor interface, which any such actors must implement). IsValid is not used for selection. It is just a normal validity check, no magic under the hood.

Suggest checking out Epic’s Content Examples project if you need more information.

Thank you for your prompt response.
I forgot to look in the detail panel on the actual map.

I was thinking the array was global and populated in code somewhere and then
the for each loop looked at all of the BP_NavigatorPawns and then
The isValid node somehow selected the right Pawn.
And I really wanted to know how that was even possible.

But now it is all clear. I understand what you did.
The array is set by the level designer in the editor and
The way you set it up anyone can change it in the editor.

Thanks again for sharing this project. It is really great work.
