as you can see, the "laser" shot, will blow the character away, in the blowAway status, i changed character's fixture by updating all vertices of each fixtures, and then called body.SynchronizeFixtures.
but as you can see, if i continusly call applyForce to character to let it run, and if now change it's fixtures, it will penetrate from walls....
i don't know what should i do to fix this, is the way i used to change the fixtures wrong?
there are some extra info:
this box2d is a ported web version from c++ version: https://github.com/flyover/box2d.ts
the game runs under 60+FPS so there is no low FPS problem. (with box2d 1/60 fixed update)
but i still see some chances that small body will penetrate from edge shapes sometimes (if with a relatively big velocity), what is the potential problem will cause such penetration issue in box2d? i guess the issue in the video is caused by this too? or just i don't know how to change a fixture at runtime correctly?
there is a video clip to reproduce it: https://youtu.be/NfPkbFgw30g
