This would be a useful feature for certain cases, and involve a physics engine in order to do collision detection. Looks like similar functionalities have been added into MASON (a Java ABM library) as an extension:

- https://cs.gmu.edu/~eclab/projects/mason/extensions/physics2d/PhysicsEnginePresentation.pdf
- source code: https://github.com/eclab/mason/tree/master/contrib/physics2d
For us, there should be several 2d physics engines available in Python. I'm wondering whether it makes more sense to have it as a separate Mesa extension, like the case for MASON.

Yeah, there should be some that already exist.

As a workaround, we can randomly assign agents' location to avoid them standing on top of each other. These are demonstrated in some example models in this repo:
raster data model
In the Population model, to assign random positions to people within the same raster cell:
mesa-geo/examples/population/population/model.py
Lines 22 to 32 in e6be96d
vector data model
In the GeoSchelling (Points & Polygons) model, to assign random positions to people within the same polygon:
mesa-geo/examples/geo_schelling_points/geo_schelling_points/space.py
Lines 27 to 32 in e6be96d
As mentioned above, physics engines won't be implemented within mesa-geo for now. Hence I'm closing this issue as won't fix. But pls feel free to continue the discussion here. We can also convert this to a discussion if needed.
