Physics Bug: Formula Made Snowball Clip Through and Fly Away #549

Closed alhardwarehyde closed 10 months ago

alhardwarehyde commented 1 year ago

Description

From HN: I was able to solve the first puzzle by placing a 1/X singularity next to the snowball. It correctly rolled down but the just clipped through and blasted away. It is very hard to cover these sorts of cases with a naive physics model because the numerics get messy very quickly. Very cool project.

This seems like an edge case that probably isn't worth the effort to fix. I feel like this bug needs to be triggered intentionally, but I might be misunderstanding.

In a way this is actually correct behavior, at least in the “point-body” simplified physics model used for the balls. Of course, it should really get stuck wedged in the graph, but there is no way to make that happen without greatly increasing the complexity of our physics engine.
