Module:GameSkills

Module:GameSkills

Module:GameSkills renders skill data from Data:skills.json into a reusable infobox-style table.

It is intended to be used via a template (for example Template:Skill) so that skills can be embedded on any page without creating individual skill pages.

This module:

• Loads data via Module:GameData → GameData.loadSkills().
• Looks up skills primarily by display "Name" (what editors use), with "Internal Name" as a fallback.
• Builds a table with only the fields that actually exist for that skill.

---

Data source

Skill data comes from Data:skills.json, which is a JSON page with this top-level structure (see Module:GameData/doc for full details):

{
  "version": "SpiritVale-0.8.2",
  "schema_version": 1,
  "generated_at": "2025-12-12T17:24:05.807675+00:00",
  "records": [
    {
      "Name": "Some Skill",
      "Internal Name": "SomeSkillInternalId",
      "...": "other fields specific to skills"
    }
  ]
}

Each record is a single skill. Important keys:

• "Name" – the display name (what players and editors will usually see and use).
• "Internal Name" – the stable ID used internally and available as an optional parameter for power users and tooling.

---

Output

For a given skill, the module renders a table with the CSS class spiritvale-skill-infobox.

Depending on what exists in the JSON record, the table may include:

• Header row with skill name (and icon, if present).
• Icon (from "Icon", as a file name like skill-example.webp).
• Description.
• Type information:
  • Damage Type
  • Element Type
  • Target Type
  • Cast Type
• Max Level.
• Users:
  • Classes
  • Summons
  • Monsters
  • Events
• Requirements:
  • Required Skills (with required level)
  • Required Weapons
  • Required Stances
• Mechanics:
  • Range
  • Cast Time / Cooldown / Duration
  • Mana Cost
• Damage and scaling:
  • Main Damage (base and per-level, where present)
  • Scaling (stat-based contributions)
• Status interactions:
  • Status Applications (status name, scope, basic duration/chance info)

Rows are only shown if the underlying field exists in the JSON for that skill.

---

Public interface

The module exposes a single entry point for templates:

GameSkills.infobox(frame)

This is usually called via #invoke from a template, not directly from pages.

It accepts the following parameters (either passed directly or via a wrapper template):

• 1 – unnamed parameter; treated as the skill "Name".
• name – explicit display "Name" of the skill (equivalent to 1).
• id – "Internal Name" of the skill (optional fallback / power use).

Lookup order:

1. If name or the first unnamed parameter is provided and matches a record’s "Name", that record is used.
2. Otherwise, if id is provided and matches an "Internal Name", that record is used.
3. If nothing is found, a small error message is returned and the page is categorized for tracking.

Example direct usage (not recommended; normally use a template):

No skills found for: GameSkills

or:

No skills found for: GameSkills

---

Template:Skill

The recommended way to use this module is via a small wrapper template, for example:

Template:Skill

 No skills found for: GameSkills

Typical usage on any page:

Bash

Level Select Level 10 / 10 Damage Melee Element Neutral Target Enemy Cast Target
Classes	Warrior, Weaver
Monsters	Ashrend, Goblin King
Required Skills	Axe Mastery (Lv.1)
Range	0
Area	Distance: 0 Size: None

or, explicitly:

Internal IDs can still be used when needed:

Unknown Skill: Bash_InternalId

This keeps page wikitext simple while centralizing all JSON loading and formatting logic inside Lua.

-- Module:GameSkills
--
-- Renders active skill data (Data:skills.json) into an infobox-style table,
-- and can also list all skills for a given user/class (page name).
--
-- Features:
--  - Per-skill Level Select slider (client-side JS updates .sv-dyn spans)
--  - Default level = Max Level
--  - .sv-skill-card + data-max-level / data-level hooks for JS
--  - Uses dynamic spans instead of long Lv1/Lv2/... lists
--  - Unified top band: Level Select (left) + Type/Element/Target/Cast (right)
--  - List-mode: wraps all skills in one wrapper panel + stable .sv-skill-item divs
--
-- NOTE: We add a small amount of inline styling on the top-band inner panels
-- (Level Select + Type box) so light mode remains readable even if a skin/theme
-- class selector isn’t reliable.
