I watched your overview video and the first in the series, and it looks like you have this sorted. I stopped working on it a while ago, but it looks like moving the capsule every tick does the trick (instead of trying to freeze it, then teleport later on like I was doing).
Thanks so much for making that tutorial series. I haven’t watched the rest yet, but I like the way you illustrate each problem you face, then show the solution to it, very well structured. Also big thanks for finding all the questions and threads it might be relevant to, and informing everyone.
