I need a system like this. Detect the unit group according to their locations.

[JFAMAP]

Hello. Let me try to give you an example. Let's say there are 7 different regions.
When units enters one of them, they will be added to unitgroup. This group changes in every new region and regions have their own proirities.
You can check my AI System actually if you want to see details
My main objective is detect closest unit to AI_HERO owned by specific player and right click on them
Second part is detect this AI_HERO met with the unit

English is not my native language and i hope i have explained the situation.
Tricky part is, units are spawning in every 30 seconds. That means there can be another unit wave enters and follows the route.
I just want to pick AI_HERO make it go to the closest player 1 unit then detect this AI_HERO met with the units.

Maybe this one is super easy for the someone like me who created ai system for moba but currently i am tired and cannot think properly. You know that feel..
I spent my last energy for my paint and English skills..
