How can I get seekers on specific grids?

I want to get seekers on specific grid in range.

ex) get all seekers on the grids in radius 3 from 0,0,0

I think using trigger or checking all seekers, but In game has over 200 seekers.
so maybe It will have many lag in mobile.

I using pro version but I have no idea how to get seekers on specific grid.

how can I get seekers?

Hi

This package does not use any kind of lookup for Seekers, however it is easy to write your own.
The simplest, but perhaps not the most performant option is something like

using System.Linq;

Seeker[] seekers = FindObjectsOfType<Seeker>();
float range = 3.0f;
Vector3 point = new Vector3(0,0,0);
Seeker[] inRange = seekers.Where(s => Vector3.Distance(s.transform.position, point) <= range)).ToArray();
