[Warning] Avoid upgrading to Godot 3.4, if you're...

...using Kinematic bodies with friction, gravity, jumping and things like move_and_slide.

This made what were super tight, responsive and most importantly expected (=the same every time) controls to become random and erratic.

It gets even worse in conjunction with other objects like moving platforms.

Luckily, re-downloading v3.3.4 fixed everything and all is good again.

Are you sure about this? If so, I would recommend making a reproduction project and submitting a bug report. But in my testing 3.4 works fine.

Actually, you are right. I was just testing 3D last night, but I loaded up a 2D project and indeed the movement was different. But I think the input and physics are improved a lot, so it might be a matter of just tweaking the speed parameters on your controls. Took me about 20 minutes and I got the movement to be the same.

There are likely some changes you need to make to your physics code, since many bugs were resolved and some workarounds are no longer necessary. It's possible that friction ends up feeling different as a result, so you may have to tweak friction values as well.

Initially, this is what I thought. But funny enough, I have not hacks in my current code.

In 3.4, I started adding hack after hack for mediocre results, and reverting to 3.3.4 fixed everything.

Something really weird, in my case, is that let's say 2D platform velocity is added to the player velocity in case of a jump, even though there is no reason to do so. Let's say I have a platform moving on the Y axis. If the player jumps while the platform moves up, I jump twice as fast and far. Half as fast and far when moving down.

This, of course, is wrong. If I jump, I jump. No matter what the platform is doing. One example of many...

It might just be the way you coded it. I don't think Godot 3.4 is broken (still only tested for 2 days) but they did change a lot of stuff, so I'm not surprised there could be differences.

Instead, that sounds like the physics are working well. If the player is resting over the platform, the frame of reference is the platform.

Edit: I've just tested and it doesn't work that way for me. I'm using move_and_slide in a KinematicBody2D and it isn't affected by the platform movement.
