PlayerEX - MT Inventory Weight

Connects PlayerEX progression with MT Inventory Weight, allowing PlayerEX level and a configurable PlayerEX attribute/skill such as Carrying to increase maximum inventory weight.

PlayerEX Inventory Weight

PlayerEX Inventory Weight is an add-on for MT Inventory Weight and PlayerEX: Directors Cut.

It connects PlayerEX progression with inventory weight capacity, allowing a player's PlayerEX level and/or a configured PlayerEX attribute/skill to increase maximum inventory weight.

This mod is not standalone.

Required Dependencies

This add-on requires:

PlayerEX also requires its own dependencies, such as Data Attributes: Directors Cut and owo-lib. Install PlayerEX through Modrinth or your launcher so its required dependencies are installed correctly.

Recommended versions:

  • Minecraft: 1.20.1
  • PlayerEX: Directors Cut: 4.0.5+1.20.1 or newer
  • MT Inventory Weight: 2.0.1-1.20.1 or newer

Features

  • Fully customizable with fzzy_config — server-side synced config for gameplay values
  • Adds integration between PlayerEX and MT Inventory Weight
  • Uses the player's PlayerEX level to modify max inventory weight
  • Uses a configurable PlayerEX attribute/skill to modify max inventory weight
  • Adds support for a custom Carrying attribute
  • Can add Carrying directly to PlayerEX's existing primary attribute list
  • Supports flat and multiplier-based capacity scaling
  • Supports refunding Carrying points through PlayerEX refund logic
  • Supports two capacity modes:
    • EVENT_MODIFIER
    • INVENTORY_WEIGHT_ATTRIBUTE

Carrying Attribute

The add-on registers a custom PlayerEX-style attribute:

playerex_inventoryweight:carrying

When enabled, this attribute is added directly to PlayerEX's normal primary attribute menu alongside:

Constitution
Strength
Dexterity
Intelligence
Luckiness
Focus
Carrying

This means there is no separate Inventory Weight screen. Players can spend PlayerEX skill points on Carrying from the normal PlayerEX UI.

Capacity Modes

EVENT_MODIFIER

This is the recommended mode.

The add-on reads the configured PlayerEX attribute value and modifies MT Inventory Weight's max weight through the Inventory Weight event system.

This mode supports:

  • flat bonuses
  • multiplier bonuses
  • PlayerEX level scaling
  • PlayerEX attribute/skill scaling

Example:

PlayerEX level multiplier: +1% per level
Carrying multiplier: +5% per Carrying level

INVENTORY_WEIGHT_ATTRIBUTE

This mode applies a modifier directly to the MT Inventory Weight max-weight attribute:

inventoryweight:generic.max_weight

This is best for flat bonuses, such as:

+10 max weight per Carrying level

For multiplier-style scaling, EVENT_MODIFIER is recommended.

Configuration

The add-on uses a synced server config.

You can configure:

  • whether the integration is enabled
  • minimum max weight
  • flat bonus per PlayerEX level
  • multiplier bonus per PlayerEX level
  • which PlayerEX attribute/skill is used for capacity scaling
  • flat bonus per configured skill level
  • multiplier bonus per configured skill level
  • whether the custom Carrying attribute is enabled
  • whether Carrying is added to PlayerEX's primary attribute list
  • whether the add-on uses event-based scaling or the Inventory Weight attribute

Default-style scaling:

level.multiplierPerLevel = 0.01
skill.attributeId = playerex_inventoryweight:carrying
skill.multiplierPerLevel = 0.05

This gives:

+1% max weight per PlayerEX level
+5% max weight per Carrying level

Example Scaling

Base max weight: 100
PlayerEX level: 10
Carrying level: 10

Level multiplier: 1.10
Carrying multiplier: 1.50

Final max weight: 165

Notes for Modpack Developers

The custom Carrying attribute must be available on players through Data Attributes. The add-on includes the required data files for:

data/playerex_inventoryweight/data_attributes/entity_types/player.json
data/playerex_inventoryweight/data_attributes/overrides/carrying.json

If you want to use an existing PlayerEX attribute instead of Carrying, set the config value to one of these examples:

playerex:constitution
playerex:strength
playerex:dexterity
playerex:intelligence
playerex:luckiness
playerex:focus
playerex:mining
playerex:smithing
playerex:farming
