Wx78 Modules

Based on game build 722832 | Last updated: 2026-04-27

Overview

wx78_modules.lua is a prefab factory file that generates multiple WX-78 upgrade module entities from definitions in wx78_moduledefs.lua. Each module prefab is created via MakeModule(data) and attaches client-side components (transform, animstate, network) in fn(), then server-side gameplay components (inspectable, inventoryitem, upgrademodule, finiteuses) in the master-only section. Modules are inventory items that can be slotted into WX-78 and consume uses when removed, with skill tree bonuses affecting consumption rate.

Usage example

-- Modules are spawned by prefab name (generated from module definitions):
local inst = SpawnPrefab("wx78module_processor")

-- Access module properties (client-safe):
local netid = inst._netid
local slots = inst._slots
local modtype = inst._type

-- Server-side: check component state
if TheWorld.ismastersim then
    local uses = inst.components.finiteuses:GetPercent()
end

Dependencies & tags

External dependencies:

• wx78_moduledefs -- provides module_definitions table with module data (name, slots, type, callbacks)

Components used:

• inspectable -- allows players to examine the module
• inventoryitem -- enables carrying in inventory slots
• upgrademodule -- handles slot requirements, type, and activation/deactivation hooks
• finiteuses -- tracks module uses and triggers removal when depleted

Tags:

• None identified

Properties

Property	Type	Default Value	Description
assets	table	---	Array of Asset(...) entries: ANIM (wx_chips.zip) and SCRIPT (wx78_moduledefs.lua).
_netid	number	---	Client-readable module network ID (set in fn()).
_slots	number	---	Client-readable number of upgrade slots required (set in fn()).
_type	string	---	Client-readable module type identifier (set in fn()).

Main functions

on_module_removed(inst, owner) (local)

• Description: Callback triggered when a module is removed from WX-78. Consumes uses from finiteuses component unless owner is currently swapping modules. Consumption rate is halved if the "wx78_circuitry_betterunplug" skill is activated.
• Parameters:
  • inst -- module entity being removed
  • owner -- WX-78 entity owning the module
• Returns: None
• Error states: None

MakeModule(data) (local)

• Description: Factory function that creates a Prefab object for a single module definition. Builds an inner fn() constructor closure that captures data from outer scope. The constructor creates the entity, adds Transform/AnimState/Network components, sets animation bank/build from module data, configures inventory floatable scale based on slot count, and sets client-readable properties (_netid, _slots, _type). Server-side attaches gameplay components (inspectable, inventoryitem, upgrademodule, finiteuses) and configures upgrademodule hooks. Returns a Prefab table with name "wx78module_"..data.name.
• Parameters: data -- module definition table from module_definitions containing name, slots, type, callbacks, and optional overrides.
• Returns: Prefab table
• Error states: Errors if data.name, data.slots, data.type, or callback fields (activatefn, deactivatefn, addedtoownerfn, removedfromownerfn) are nil/invalid when accessed in the inner fn() constructor — no validation guards present before data access.

Events & listeners

• Listens to: None directly registered in this file.
• Pushes: None directly pushed in this file.
• Component events: finiteuses component triggers percentusedchange event internally; SetOnFinished(inst.Remove) causes entity removal when uses reach zero.
