I get that this is a very small change that'd probably take more time than it's worth, but it'd make the game feel much smoother, and for my purposes, it'd make obstacle courses smoother and more fun.
[This obstacle course I've been working on] is what the fan propulsion mechanic is supposed to look like. I made it before realizing that other players, even with about 30 ping, can't even do the first jump because it lurches them off of the fan before it can even propel them upwards. This might be a design flaw on my part, but the fact that I can do it perfectly while other people have trouble just because of latency is a bit of an annoying problem. I can resort to replacing everything with trampolines, but that isn't nearly as fun as the feeling of momentum the fans give you. Even the trampolines, however, take time to respond to the player and actually launch them if they have higher ping.
I don't know how hard it would be to make player-physics interactions clientside, or if that would cause problems that are greater than its solutions, but at least for this niche use, it would fix my problem. I really want to keep working on this project by adding more jumps and decorating each one. I'll have to reimagine it or maybe even drop it if it isn't fun for other people. Thanks for watching/reading if you made it this far.
