# why?
non-player facing
we're going to need fast lookups for "is this thing in range of this
other thing" at some point, for things like telecomms
this current solution consumes about 16KB per reservation level
we also add the capability to use spatial grids to quickly get atoms on
a level.
spatial grids are also at 16KB per grid, per world level
all in all worth it in my opinion.
3/3 is world structs and the fun that comes with that
this pr has:
- transitions
- new multiz system
- lookup optimizations
- misc updates
