Module:ItemData

Loads data from Data:ItemData.json

Usage

{{#invoke:ItemData|FUNCTION_NAME|PARAMETER1|PARAMETER2}}

Functions

• get_cost|ITEM_NAME
  • Returns the total cost including components.
• get_type|ITEM_NAME
  • The ItemData.json has different names for each category: Weapon = Weapon, Vitality = Armor, Spirit = Tech. This function will return Weapon, Vitality, or Spirit
• is_active|ITEM_NAME
  • returns true/false
• get_prop|ITEM_NAME|PROPERTY
  • Returns the value of one of the item's properties. Check the json file for item properties.
  • Automatically appends "%" to percentage-based properties and shows scaling templates (Boon/Ss) when applicable.
• get_codename|ITEM_NAME
  • Returns the item's codename in game files
• get_component_name|ITEM_NAME
  • Returns the display name of the item's first component (if any)
• get_headcount
  • Returns the number of items that are not disabled
• get_builds_into|ITEM_NAME
  • Returns a formatted list of items that use this item as a component, rendered with ItemIcon templates (e.g., "ItemIcon templates separated by commas and 'and'")
• get_builds_into_count|ITEM_NAME
  • Returns the number of items that use this item as a component
• get_builds_into_name|ITEM_NAME|INDEX
  • Returns the display name of the nth item (1-indexed) that uses this item as a component

Example

To get the total cost of Boundless Spirit you'd type:

{{#invoke:ItemData|get_cost|Boundless Spirit}}

and it would return:

6,400

To get Boundless Spirit's Spirit Power:

{{#invoke:ItemData|get_prop|Boundless Spirit|TechPower}}

and it would return:

30

If an item key (English name) has been provided, the item name can be replaced by:

{{#var:item_key_or_en}}

for example:

{{#invoke:ItemData|get_prop|{{#var:item_key_or_en}}|TechPower}}

To get Boundless Spirit's codename:

{{#invoke:ItemData|get_codename|Boundless Spirit}}

and it would return:

upgrade_boundless_spirit

To find what items Debuff Reducer builds into:

{{#invoke:ItemData|get_builds_into|Debuff Reducer}}

and it would return:

Spellbreaker and Unstoppable
