Property Modifier Mod (1.21.1, 1.20.1) – Tweak Block & Item Properties

Property Modifier Mod allows you to tweak certain aspects of Minecraft with the use of a config file. This includes properties of several different items and blocks.

Features:

Here is a list of tweaks possible through a config file:

For each block or blockstate:

• Hardness
• Tool requirement (true – tool is required to get drops, false – tool just breaks the block faster)
• Light level

For each block:

• Blast resistance
• Slipperiness
• Speed factor and jump factor (as used on honey blocks in vanilla)

For each item:

• Durability (only if the item already has one, so you can’t set durability on a diamond)
• Max Stack Size (only if the item is already stackable, so making netherite swords stack to 64 won’t work)
• Item Group (aka creative tab) [subject to change in 1.20]
• Fire immunity (netherite has this already, can be turned off for netherite items too)
• Rarity (aka item color)
• Enchantability
• Repair item (if the item can be damaged)

For each armor (excluding the elytra):

• Armor value
• Toughness value
• Knockback resistance

For each tool, sword and trident:

• Attack damage
• Attack speed

For each tool:

• Efficiency

For each enchantment:

• Rarity (how often it appears at the enchanting table)

Item groups/Creative tabs: [subject to change in 1.20]

• Add new item groups
• Option to remove empty item groups
• Which enchantment books appear in which item group(s)
• Backgrounds and search bars

For the composter:

• New items to accept
• Option to clear old items and add only the ones set by this mod

For axe, shovel and hoe:

• New stripping/pathing/tilling transitions
• Option for every of these to clear out old transitions

Entities:

• Apply attributes upon joining the world
