I just updated to the latest LootTweaker-0.3.0+oldparsing-MC1.12.2.jar as the previous version LootTweaker-0.3.0+MC1.12.2.jar was archived.

However, looks like I need to refactor my mobdrops.zs loottweaker scripts as they are all throwing an error now. My question is, how can I refactor this bit of code to work with the new version?

Code that used to work:

import loottweaker.LootTweaker;
import loottweaker.vanilla.loot.LootTable;
import loottweaker.vanilla.loot.LootPool;
import loottweaker.vanilla.loot.Conditions;
import loottweaker.vanilla.loot.Functions;

## minecraft:zombie
## get existing loot table for a mob with existing table
val zombieTable = LootTweaker.getTable("minecraft:entities/zombie");
## inject additional custom pool
val zombiePool = zombieTable.addPool("RottenEconomy", 1, 2, 1, 2);
## add drops for when killed by player
zombiePool.addItemEntry(<minecraft:rotten_flesh>, 10, 1,
    [Functions.setCount(0,3), Functions.lootingEnchantBonus(1, 2, 3)],
    [Conditions.killedByPlayer()]
);

Error that I get when running /ct syntax

ERROR: loottweaker/mobdrops.zs:13 > 2 methods available but none matches the parameters (ZenTypeNative: crafttweaker.item.IItemStack, int, int, any[], any[])
This is usually an error in your script, not in the mod
addItemEntry(ZenTypeNative: crafttweaker.item.IItemStack, int, int, Optional string)
addItemEntry(ZenTypeNative: crafttweaker.item.IItemStack, int, Optional string)

Both the old parsing documentation which the changelog says to use and the latest documentation (?which i guess is actually old now?) seem to suggest there are more than 2 methods available for addItemEntry but /ct syntax doesn't show them??

Thanks for the help. Let me know if I should just keep using the old JAR file despite it being archived? Maybe I'm just confused!? Maybe this note in the changelog means something that I don't understand: suffixless methods do not have variants that accept functions and/or conditions. ?

Versions

There aren't, look at the names. For 0.3.0-oldparsing there are exactly 2 methods named addItemEntry. The method you linked is addItemEntryHelper

the latest documentation (?which i guess is actually old now?)

The changelog for 0.3.0-oldparsing links to separate docs for a reason. Why are you looking at the other docs?

Not a good idea. I don't archive versions unless they're badly broken in some way.
However if all goes well 0.3.1 should be out around this weekend with a fixed new parser. It'll be compatible with 0.3.0, unlike 0.3.0-oldparsing, which was a quick and temporary workaround for an issue that had me stumped. 0.2.0 and 0.3.0-oldparsing scripts will work in 0.3.1, but deprecation warnings will be generated if some methods are used.

Oooof, thanks for the Helper bit, I refactored my couple hundred lines of script in a few seconds with :%s/addItemEntry(/addItemEntryHelper(/g hahah...

Glad I can update off the archived version now and good luck with the 0.3.1 parser updates!

Cheers!
