This mod currently lets you change the XP drops of blocks and entities. It lets you specify lists of operations to perform on the XP drops of either all block/entities or specific ones (by ID or TAG). You can also specify a range for your value if you want a randomized amount. Operations are ordered by their specified priorities.

Note: This is a server-sided mod and the configuration file will be generated per-world inside the serverconfig folder.

Example configuration for block breaking:

The following sets the XP drops of all blocks to 0. Then it adds 0-10 XP for all blocks tagged #minecraft:mineable/shovel and sets the XP of blocks tagged #forge:ores to 2-5.

#Settings for block breaking
[block_breaking]
	#Available operations: [SET, ADD, SUBTRACT, MULTIPLY, DIVIDE]
	#List of global operations. Format: '[operation],[min],[max],[priority]'
	#Global operations are run before any unique operations.
	#Examples:
	#'set,0,0,0' - Sets the xp of all blocks to 0.
	blockBreakGlobalOperations = ["set,0,0,0"]
	#List of unique operations. Format: '[block_id/tag_id],[operation],[min],[max],[priority],[is_last]'
	#Examples:
	#'minecraft:dirt,set,2,2,0,true' - Sets the xp drop of the dirt block to 2, takes highest priority and stops any additional operations.
	#'#forge:ores,multiply,1,2,1,false' - Multiplies xp drop of all blocks tagged forge:ores by 1-2, allows additional operations.
	blockBreakOperations = ["#minecraft:mineable/shovel,add,0,10,0,false", "#forge:ores,set,2,5,0,false"]
