Pufferfish's Skills - MT Inventory Weight
by MEGATREX4
Pufferfish's Skills InventoryWeight links MT Inventory Weight to Pufferfish's Skills, so skill progress can raise how much a player may carry.
What it does
Players gain a larger maximum inventory weight through their skill tree. The add-on reads the experience level of a skill category and passes it to MT Inventory Weight, which already computes the weight from its base configuration, armor and pockets added by other Inventory Weight add-ons. Its max-weight event is listened to, so the value it reports is the one that stacks with those sources.
Two routes lead to the same result. A skill node can grant the registered inventoryweight:generic.max weight attribute directly, through a puffish skills:attribute reward. Alternatively, the add-on scales one configured category's experience level or the sum of several categories. The mod bundles an optional Carrying skill tree that can be enabled per world, with its nodes gated behind earlier ones. Experience is earned by mining blocks and crafting items.
The mod needs Fabric API, MT Inventory Weight and Pufferfish's Skills. The server must run it, while players may leave it out, so the client side is optional. The synced server config is handled through fzzy config. The code and assets are released under the Creative Commons Attribution 4.0 license and the mod is not open source.
Key features
Skill-based weight capacity
Skill progression raises the maximum weight a player can carry, with flat and percentage bonuses on different nodes.
Attribute reward nodes
Skill nodes grant the registered weight attribute through the Pufferfish reward type, so no custom code is needed in a datapack.
Carrying skill tree
An optional built-in tree, shipped as a datapack that a world can enable when it is created or from its datapack list.
Category scaling
The add-on can scale one category's experience level or the sum of several, and the skills screen opens with K on the Carrying category.
