Retire Forum in Favor of GitHub Issues
I'm toying with the idea of disabling this forum and moving discussion to GitHub issues in an effort to minimize communication paths that I monitor. Some thoughts, in no particular order: ⋅ Most of the sample programs that have been posted I've put into the dyn4j-samples project on GitHub....

Re: ContactListener end() method not getting called when normal body stops overlapping with sensor body
This was changed in the 3.3.0 version so that sensed contacts work exactly like normal contacts. See the release notes for more information on the change and it's implications.

Re: Detecting when a player "is on the ground"
Probably too late, but I updated the SimplePlatformer.java sample program to help illustrate how you might achieve this. Keep in mind that it's just a sample and you'd probably have something more structured.

Re: e=1, behaving as super-elastic collision
Looking at this deeper, here is what is happening: Imagine two bodies, A and B. A is a ball falling and B is a floor. t1 and t2 represent 2 timesteps, one after another. ⋅ t1: A and B velocities are integrated ⋅ t1: Collision resolution (none in this step) ⋅ t1: A and B...

Re: Stuck at world.step
I understand the cause, but I'm looking for a reproduction case so I can test my fix and add a JUnit test for it. If you happen to see this again in debug mode, see if you can .toString() the shapes and transforms. I still haven't been able to produce this problem myself. Either way, the GJK code sh...

Re: Stuck at world.step
Thanks for finding this. Do you have a test case that I could use to reproduce?
I just need the shapes and their transforms to setup a test.

Re: Stuck at world.step
Any more info on this? Still curious if there's a problem with GJK or if you encountered the problem with SAT (just later)?
