Spatial Hash Support #179

Closed LennyPhoenix closed 4 years ago

LennyPhoenix commented 4 years ago

I was reading up on how to apply spatial hashing when I discovered that Chipmunk itself actually has an option for spatial hashing instead of the standard axis-aligned bounding box tree.

Source: https://chipmunk-physics.net/release/ChipmunkLatest-Docs/#cpSpace-SpatialHash

Could we get an option to enable this?

Hi! Definately, just added it to master. So far quite untested, so would be great if you could try it.

viblo commented 4 years ago

Realized I should probably give an example use case also:

dim = 10
count = 1000
space.use_spatial_hash(dim, count)

Thank you for the quick response and implementation!

Ill try it out @viblo. Do I need to clone this repo directly or have you already released it to pypi?

viblo commented 4 years ago

Clone the repo is quickest. I can make a release later, maybe with a week or so.
