LootTweaker is an addon for CraftTweaker that allows loot tables to be tweaked with ZenScript files. The vanilla loot table system is limited to overriding existing loot tables or creating entirely new ones.
LootTweaker allows you to make small or large tweaks to loot tables, without having to override the table completely.

FAQ
Will there be a 1.13/1.14/1.15/... version?
Currently I'm prioritising an overhaul for LootTweaker 1.12 that's needed to add some much requested features. Once that's done I'll investigate updating to the latest MC version that has stable Forge releases at the time.
Can LootTweaker edit mob/structure/whatever loot?
LootTweaker edits loot tables. If a vanilla mechanic or mod mechanic uses loot tables, LootTweaker can edit those tables. To find out if a mod uses loot tables, check its documentation or ask the author.
Can LootTweaker create new loot tables?
Yes, this feature was implemented in version 0.2.0. See the documentation for the class loottweaker.LootTweaker for details.
Can LootTweaker automatically find and remove all of an item from loot tables?
No, though the feature is being worked on. There is no estimate for when it will be ready.
Can LootTweaker be installed only on the server?
Server-only installation is possible with LootTweaker 0.1.7 or later. However CraftTweaker requires that it is installed on both server and client.
Clients without LootTweaker installed will still be able to use LootTweaker commands, but the feedback messages will be untranslated.
Note that loot table dumps occur serverside.
Client-only installation of LootTweaker is not supported.
What happened to LootTweaker 0.0.9?
0.0.9 was extremely broken, crashing any dedicated server that used any of its functionality due to an oversight on my part while trying to improve the warning and error messages. Initially I archived it, making it unavailable for direct downloads, but still available to packs that were using it. However, I've received many requests from users for 0.0.9 because servers they are playing on use it, so I've deleted it. It's really broken, update to 0.0.10.
Important Notes:
Modifications made by LootTweaker are not detected by Just Enough Resources prior to 1.12. The cause of this issue is unknown, neither I nor the JER author could figure it out.
Only LootTweaker for 1.12 receives new features. Due to large differences in the codebase caused by the port to 1.12, I can no longer develop LootTweaker for all versions simultaneously. LootTweaker for 1.10 and 1.11 will continue to receive bugfixes however.
A Forge version of at least 14.23.5.2779 is required
Want more loot conditions/functions?
Take a look at More Loot Stuff. If the condition/function isn't already in More Loot Stuff, suggest it and I'll see what I can do.
Need help or have a question?
I have a discord server with a dedicated channel for LootTweaker. You can of course also contact me here, but I'd advise going to the discord server as you can get help there when I'm otherwise occupied.
Have a suggestion?
Create an issue hereor just comment on this project.
There is no discord link at this page and the discord link at the wiki doesnt work.

Hey there, is there a way to make custom added loot table from your mod available ? I mean in the total game and not only from a save ?
Because when I use other mods which are supposed to load every loot tables to make custom chest I don't see the ones that I created with your mod.
I am still able to perfectly edit loot tables which are already available.
In reply to DrBLOOD95:
Be more specific than "other mods". I can't tell you anything without knowing how they detect loot tables.
In reply to Daomephsta:
For example Reccurent complex can use an object which detects all chest loot in order to make your custom buildings. Same for ancient warfare an item looking like a wand can spawn a chest with any sort of loot inside, you must choose it first and the custom loots from that mod won't appear.
In reply to DrBLOOD95:
Detecting all loot tables is difficult. There's a list of all vanilla loot tables, which mods can add to, but it's not necessary at all. Vanilla only uses said list to preload all its loot tables on world load. LootTweaker doesn't add tables you create to that list, because I'm unsure what it actually means to add a table to that list. Vanilla only includes tables built into the game in that list, world data tables aren't included.
LootTweaker used to use that list to check table existence, but because it's entirely optional, many mods don't add their tables to it as they aren't even aware it exists. In the end it was easier to detect loot tables by scanning the JARs of installed mods.
Are there any plans for 1.15.2?

I've added update plans to the FAQ
Is there a way to add a loot table to a mob that doesn't have one?

Hello There!
I am working on a mod pack, and I have recently included a mod which adds custom music discs to Minecraft 1.12.2.
https://www.curseforge.com/minecraft/mc-mods/custom-disc
The mod itself works fine, adding my five working music discs to the game, but sadly, the mod doesn't give the player any option for adding the discs to creeper loot tables. I came across your mod, and although I see its able to add more loot to loot tables, I'm not sure how to add extra music discs with the condition that a skeleton has to kill the creeper.
Many thanks in advance!
In reply to garfieldwxg55:
Vanilla 1.12 doesn't have the necessary loot conditions for that, it hardcodes the creeper music disc drops. I'm not aware of any mods that add the necessary conditions either.
It's possible to achieve with a CraftTweaker script though, using the Entity Drop Functions API.
Will there be a 1.16+ version of LootTweaker? I don't see a branch, so I'm not sure. Thank you.
In reply to GregD:
Eventually. Right now I'm prioritising an overhaul that's needed to add some much requested features.
In reply to Daomephsta:
Sounds good. Thank you.
Nice!
rightso i've been reading this and testing with different numbers for a while now.. i'm attempting to add a single item that has a 1 in 100 chance of being dropped and found that i can get it to drop about 50 in 100 by giving it the value 1 (by replacing the 5 in the example) but anything less than 1 (0.9 for example) results in nothing dropped at all.. i see it's a relative weight so would this mean i need to add a 100 percent chance for a mob to drop air (with a value of 100) along-side the drop i wish with a value of 1? feels like there must be a better way to do this.. tbh idk if adding air would work, what is the preferred method. i have read the wiki on weight an it didn't detail this. even the given example appears to drop 100% of the time with the value of 5, i gather this is because the lower value for drops in this example is 1, which makes me wonder why the 5 is necessary given that the example has only a single entry.
hope i explain successfully here, i seem to have trouble being understood with this kind of thing
In reply to Forge_User_16056450:
ok i got around this by adding rotten_flesh to the zombie drops for example

I'll get back to you on this in a bit. Currently busy with Uni.
