Bukkit

In reply to toastbrot031:

Hmm, my 1st suggestion is to check /droprate (you can do it with an argument specifying a mob/player, or while looking at a mob/player with your cursor, and it will give a breakdown of anything impacting the drop chance). Beyond that, there have been a few other DropHeads users reporting issues with Geyser/Floodgate for Bedrock cross-play servers, although I haven't been able to replicate it. If you're still stuck after trying that, feel free to DM me here on Bukkit or on Discord

Still planned, but no certain ETA.
I've did play around a bit with the Fabric API recently to try and learn the basics of it, but probably not going to attempt a fabric version of DropHeads anytime in the near future.

HOWEVER: you could try the mod "Cardboard" which says it adds support for plugins built on Bukkit/Spigot API. I haven't tried it yet myself but this could give a realistic way to have DropHeads as a singleplayer (or fabric server) mod: https://modrinth.com/mod/cardboard

In reply to livvyjed:

Drop percentage chances can be edited in the `head-drop-rates.txt` config file
"dropheads.canbehead" is a permission not a command - it should be true by default, so that's probably not the issue.  There's also a config file which lets you adjust droprate based on the spawn conditions of mobs, e.g. mobs from spawneggs have a 0% chance in the default config, so that could potentially be your issue. Of course there's a lot of potential causes for why heads might not drop, my #1 go-to recommendation is to look at a zombie pig (hover cursor over it) and type "/droprate" - it will print out the drop chance and anything that is affecting it

In reply to Jacold_:

Heads for mobs (like endermen) don't actually use a head owner, it just links to a texture on the Minecraft servers (which is any current or former skin - 60% of the mob heads were all created used the same player account, but it doesn't matter since they don't store that).
E.g., bee head: http://textures.minecraft.net/texture/59ac16f296b461d05ea0785d477033e527358b4f30c266aa02f020157ffca736

Sorry that's just the technical details I thought you might be interested in.
To answer the question more specifically - yes there could certainly be a command which changes the texture URL in a head to a be a different texture URL, like
/changeowner <name of player whose skin to use, or just a URL>

However I think you could also do this with vanilla commands, specifically with "/data modify".  I'm not super familiar with vanilla commands or command blocks but I have a general idea of how it might work in this case, so if you need help figuring it out feel free to DM on Bukkit (or on Discord: same username) and we can give it a go

Uhh I thought I responded to this but I guess it got deleted (Bukkit/Mojang staff do not want to support cracked players)? Or maybe the submit button didn't work? Idk.

Either way, basically what I said before is that player heads will always be Steve/Alex on cracked servers because there won't be access to the Mojang service/api for skins.  It should still be dropping regular Steve heads though, if not (or if there is an error in the console) please DM me and we can try and work it out

In reply to stigmatic:

Thank you!  I agree it's a fun way to add some "late game" collector content; it's also adds a fun reason to design farms for obscure mobs (with no natural drops)

In reply to g_s_adler1938:

Hmm, probably the best way would be to use a "per-world-plugin" system (iirc there are plugins that let you limit certain plugins to certain worlds, but I've never used anything like that myself and don't know what it's called).

Alternatively you can actually run the two worlds on different servers linked together thru teleport, transfer packets, or Bungeecord/Waterfall (once again, I haven't done that personally so I won't be able to tell you how but I'm sure there's some resources out there).

As a final option, if you have a permission plugin that lets you customize per-world-permissions, you could use droprate-multiplier-permissions in the config.yml to create a player/group a permission that multiplies the droprate by 0 in world where you want to disable heads

In reply to lokyycs:

For counting the heads, just look at the number of lines in the head-textures.txt file (minus the comments at the top bottom).  It will vary depending on whether you enable Grumm/Dinnerbone, Sideways-Shulker, Collared-Cat/Wolf, Saddled/Carpeted Equines, and other variations, because that will increase the total # of textures which will be available.

I think currently there are ~600 with all of the above-mentioned variations turned OFF, but obviously the number goes up quite a lot when you start turning them on.

For tropical fish, it's been a WIP for a looong time.  I'm not a super talented skin artist myself, and there are not a lot of artists out there who seem super excited about the idea of creating 3584 head textures lol.  That said, I've been looking into ways to write code to do color-substitution for the 12 different models (shape+pattern), which could make the task considerably faster.

Carpeted llamas is something I've been wanting to commission for a while, but it's been on a lower priority while I was focusing on other core-feature updates, but now most of those tasks are complete, so it'll probably be something I focus on again between now and the next release.

That problem sounds like a config/compatibility issue, unless it's a bug in the latest version (although nobody else has reported it yet), perhaps try with a freshly-generated config as well as no other plugins?

Also, from before you edited the message, regarding a singleplayer release:
I've been planning for a long time to have a fabric-compatible version of the plugin (which would work for singleplayer with fabric launcher and also fabric servers), but due to my unfamiliarity with their API I haven't quite figured out how to port everything yet... This is still something I hope to complete within this year however.
