Loot Table Modifier
Makes it possible for datapacks to modify loot tables, instead of just replacing them.
Vanilla datapacks can only replace existing loot tables, which is not good for being compatible with other datapacks that may also try to replace the same loot tables.
This mod fixes that by implementing a system of loot modifiers, which do just that, modify loot (tables)!
Loot modifiers are in datapacks, meaning mods and modpacks are able to use them too!
Unlike some mods which replace stuff at runtime, Loot Table Modifier does all of its processing during data loading. This means that the mod will have no performance impact during gameplay! (Except of course if you make a zombie drop a bajillion stacks of diamonds, though that’s not the mod’s fault…)
