1.21.11 Port

[emyfops]

I've ported the 1.21.8 to 1.21.11. We will have to wait for Accessory and owo-lib to have stable releases.

(ps; use the github copy button instead of selecting, this might corrupt the patch)

3. Compile this port

Make sure you also put accessory and owo-lib in your mod folder.

I had used some parts from #79 for this. But most of the code was rewritten by hand.

[emyfops]

There seems to be an issue where the pet sees the baby turtle not invisible while everyone else doesn't see it. Im not sure what may cause this as in the code the turtle is clearly being made invisible

[FAWSInkChicken]

I built this code today to use on a server but I encountered a bug where leashing a player or mob, putting that leash onto a fence post and then try and take it off the fence post crashes the game. Now I'm not sure why this happens but the server doesn't crash and it only affects whoever tries to unleash the leashed player/mob. This occurs in singleplayer worlds as well and removing all other mods except for accessories, owolib and the collar mod still creates the same issue.

@FAWSInkChicken I have remapped the stacktrace by hand for readability. If you are a developer you could check yourself. I will look into this when I have time. I am currently in my finals for this college session and would like some time for myself.

The issue is here. I have blindly copied a mixin for #79 and did not test this feature. The pull request is not up to date with 1.21.8's changed.

@emyfops Yeah Im not really good when it comes to this stuff because this was actually my first time building a mod from source code, but I was going to try and look at it when I got home today anyways. And I completely understand needing time to yourself so I'll try my best to fix the issue on my own, good luck with your college finals!

[emyfops]

@FAWSInkChicken I have some time to fix the problem in about 6 hours.

[emyfops]

@FAWSInkChicken I had a bit of time to fix the issue. It was a pretty trivial one.

[FAWSInkChicken]

@emyfops Thank you, much appreciated 🙏

[solonovamax]

@emyfops not really sure why you needed to patch owo-lib there? all you're doing is removing the license file, which should not be load bearing...

It wouldn't compile on my machine

ah right, gradle removed archiveBaseName in the 9.0 update

this is the diff you probably want for it:
