a mod that prevent specific villagers from jumping

[rich fable]

Some in game way of making specific villagers (not all) from jumping on 1 block tall elevations, ideally reversible

Main intended use is to make easy enclosures for villagers without compromising aesthetics in creative builds. Can also be applied to simplify some survival farms/contraptions

[whole mountain]

I'm not sure if it works on villagers but I know that applying really high levels of jump boost makes the player unable to jump at all

[simple flare]

I will try making this tomorrow, but don't get your hopes up I'm bad at commiting to things

So I just noticed that this request is 12 days old... but if you still want it, here it is: https://github.com/Bombastian1230/Stop-Villager-Jumping, (Edited to add github repo)

sharing random zip and jar files triggers me.. why not post on github or something similar 😒

[simple flare]

Sure!

I made a github repo now! Link:https://github.com/Bombastian1230/Stop-Villager-Jumping

[rich fable]

Oh nice, I’ll look when I have time, thanks

[rich fable]

@simple flare tested the .jar, it works great!

I can finally create shop counters that are 1 block high and not worry that the clerk will escape. Opens up a lot of build options.

If it’s not too much to ask can you put it on forge so it’s easier to access/update?

[simple flare]

I can probably do that, would be a good chance to learn forge

[soft rain]

think they meant curseforge ;P

[simple flare]

Ah, could probably do that to.

[simple flare]

The files are under review right now, but it's getting late for me. So I'll do the rest tomorrow

This is caused by a bug on the packet, the effect packet uses byte for the amplifier, so values above 127 overflows and the client thinks it is negative, so it only applies to players

@simple flare problem: when reloading the world, villagers with the ball and chain equipped despawn.

the .jar is still in the mod folder and still functions in second session, but villagers modified in first session disappear

[simple flare]

I think I know the problem. But can't fix it right now. I'll do it when I get home

[rich fable]

No worries man, thanks for making this

Another problem I found is that the villagers with the ball and chain don’t realize that they can’t jump, and their pathfinding still behaves like they can. Not a big deal if it’s a huge pain to fix, the current Behavior is already very good

[simple flare]

I think it is fixed now. I have uploaded the files to both github, and curseforge, I cant update the behavior of the villagers, I'm not good enough at modding yet.

Sorry was busy for a while.

I checked out the new version via CursedForge, it no longer despawn the villager on load, but it seems that the ball and chain effect is also gone when reloading

[simple flare]

Huh wierd. I won't be at my computer for a few days. So I can't fix it at the moment. But I'll take a look as soon as I can.

[simple flare]

@rich fable I can't replicate the bug. Are you on a server, or using any other mods?

[rich fable]

Not on server, will try again no send mod list later

[rich fable]

Tested, the bug is that, after saving then loading the game, the ball and chain cannot be recovered as an item from the villager but is still active.

Basically:
1: put ball on villager
2: save-load the game
3: villager still cannot jump (intended)
4: crouch+right click villager with empty hand
5: villager can jump again but the ball and chain item doesn’t appear in hand again

I don’t think this is an interaction with another mod since I described the problem incorrectly at first. Also I’ve been in creative mode the entire time if that matters

[simple flare]

It should be fixed now.
