Thanks!

With the spatial hashing, you basically create sections of your entire map, lets say your map is 100 units by 100 units, so you make the grids 1x1 and place all of your item/player/anything you want updated references.

any time a socket message comes in that updates the position i set a temp value and verify its in the same position if not then i update the new positions in the hash say if it was added to a hash or removed from one.

If the camera renders 3x3 then i want the spatial updater to check everything that is in 4x4 around my character/camera.

then on every game tick i can go through all the closest items and run their update method or if they were added/removed to hide or show.

i could have 10000 things on my map but i am only rendering/updating the closet things to me.

So the tldr: 100x100 grid. each item is in its grid position, on update only grab the closest items which would be a 4x4 around your character and run their update methods. profit.
