Main module for rendering game icons.

Note: This module is not intended for direct use. Use the templates below.

Data sources

The module reads from Data:ResourceLookup.json, a pre-indexed lookup table generated by Deadbot at deploy time. When the bot uploads new game files, hero, ability, and item icons update automatically.

An additional resource for other icons can be found at Data:ResourceLookup2.json, a manually maintained table; some entries may rely on a dictionary key.

See Module:Icon/data for manual overrides, legacy items, aliases, and renames used by this module.

Usage

Any of the following templates can be used. The module automatically detects the icon type:

Note: While all four templates work identically, it is recommended to use the appropriate one for clarity (e.g., use {{AbilityIcon|Siphon Life}} even though {{HeroIcon|Siphon Life}} will also work).

Error tracking

Icons that fail to render are added to Category:Module:Icon ERROR.
