Hi everyone! 
I’m trying to understand how to make an NPC queue system from scratch in Blueprints (Unreal Engine 5.5).
I’m not necessarily looking for someone to fix my current setup — I’d really like to learn how to properly build it step by step.
Here’s what I want the system to do:
-
NPCs spawn at a set distance in front of the seller (I want to control that distance with a variable).
-
Each new NPC spawns behind the previous one, keeping an adjustable spacing (
DistanceBetweenNPCs). -
There’s a maximum number of NPCs at once (
MaxNPCCount). -
NPCs should walk toward the seller, then stop in line before reaching them.
-
When the first NPC finishes (for example after an interaction), it should move to the side, walk away, and despawn.
-
The rest of the NPCs move forward one position, and a new NPC spawns at the end of the line to replace the one that left.
So basically, I want to build a clean queue or line system where NPCs always maintain their spacing, take turns, and recycle smoothly.
If someone could explain how to set up the logic — like how to manage positions, timing, and movement between NPCs — that would really help me understand it.
I’d rather learn the structure and reasoning than just copy a fix.
Thanks a lot for any guidance or step-by-step explanation
