After yesterday I couldn’t still focus on only the simple version of the resolver. So I did try some things. But in the end it’s clear I really need to keep it simple now. That means figuring out why it offsets the entity so much when a collision happens.
It is already a bit better now. However the car can lose all it’s velocity somehow when it hits a diagonal wall. Not straight on, but from an angle. Which should definitely still push it along the wall. But that doesn’t happen.
