0002415: Weird behavior in player frames with A_Jump
I simulate a smoother foot step sound / walking animation through the use of state jumps, and there's an A_Jump(256, ...) involved and it's causing some weird behavior. I remember seeing an issue with this specific A_Jump case so it might be related.
- Use the provided, join an online game.
- Have another person (can be you connecting twice, as well) watch you move.
- Stop after moving a bit, in certain cases you'll flicker between your PLAYA and PLAYC frames.
No tags attached.

Weird. I'll investigate this shortly.

The second client is necessary, using chasecam is not enough. The issue does not require ping emulation to reproduce.

Yes, I forgot to mention these. Doesn't seem dependant on ping as I used emulation on my end and still doesn't happen with chasecam. A secondary client views the error properly.

Is this any different in 2.1.2?

It's messy in 2.1.2 as well. Flickering still happens.

We found out that the special treatment of A_Jump(256, ...) added in 2.1 causes problems and removed it from 3.0.

Is this any different in the latest 3.0 beta build?

If you mean the build here:'https://zandronum.com/forum/viewtopic.php?f=55&t=7387 [^]' -- then it still happens yes.

Yes, that is the first build that reverts the special treatment of A_Jump(256, ...).

Alright, so the issue in this ticket is not related to that special treatment then. Needs further investigation from us.
