Implements {{Item}}.
Known items are synced regularly from the upstream, but things like icons and links must be defined manually. See #JSON files to see what data files there are, and see #FAQ on specific instructions.
JSON files
JSON files that are updated automatically, syncing with the upstream:
- Module:Item/item names by item ids.json - contains 1 to 1 mapping of item IDs to their names.
- Module:Item/item ids by item lowercase names.json - contains 1 to 1 mapping of item names (lowercase) to their IDs. If a name repeats for multiple items, only a single item ID will be defined here.
JSON files that are filled manually:
- Module:Item/item ids by item lowercase names overrides.json - a 1 to 1 mapping of item names (lowercase) to their IDs. This one has a higher priority than the other one, so it can be used to override existing name → ID mappings or create new ones.
- Module:Item/item image files by item id.json - a mapping for item IDs to image files for these items. Can be a simple 1 to 1 mapping of item name to file name, or can have a whole config that allows to define multiple images per single ID (see sections below for more info). Used to add icons to items.
- Module:Item/item page links by item ids.json - a 1 to 1 mapping of item IDs to page names. Used to turn items into links to their pages (or any other page on the wiki).
FAQ
How to add new item?
New items are added automatically. This doesn't include icons - for that, see #How to add icon to item?.
Where to get item ID?
From Module:Item/item_names_by_item_ids.json.
How to add icon to item?
If you want to add multiple textures per single item, see #Adding multiple icons to item
1. Upload new icon to the wiki.
2. Go to Module:Item/item_image_files_by_item_id.json.
3. Add a new line. Follow the format: "<item ID>": "<file name>"
"WeaponLaserCarbine": "laser rifle-East-35325.png"4. Save the file. The icon should now appear when using {{item}}.
Adding multiple icons to item
Currently, the only supported use case if for items that have a different icon based on the amount of item.
1. Upload new icons to the wiki.
2. Go to Module:Item/item_image_files_by_item_id.json.
3. Add a new line. Follow the format:
"<item ID>": {
"default": "<default file name>",
"byCondition": [
{
"type": "amount",
"conditions": [
{
"file": "<file name 1>",
"min": <minimum amount 1>
},
{
"file": "<file name 2>",
"min": <minimum amount 2>
},
{
"file": "<file name 3>",
}
]
}
]
}
item ID- item ID to add icons for.default file name- icon to use when amount is not specified.file name 1/2/N- icons to use with specified amounts."min": <amount 1/2/N>- icon to use when there's at least this much of item.
Last condition entry (objects that have "file" and "min" fields) shouldn't have any condition in it (i.e. no "min" specified), because it will be used in cases where other conditions do not satisfy.
Conditions are evaluated top to bottom, meaning the file from the first one that satisfies will be used.
4. Save the file. The icons should now appear when using {{item}} and differ based on the amount.
How to add custom names to item?
When using {{item}}, you probably don't want to use item IDs because that's internal game info which is a pain in the ass to write. Gladly, there's an existing set of item names defined in Module:Item/item_ids_by_item_lowercase_names.json, which are human-readable. But not all existing items will have their names in there, because some names do repeat (for instance, various bottles named bottle).
To add new cool names and have them not be erased on new update (which happens to the JSON file linked in previous paragraph), add them to Module:Item/item_ids_by_item_lowercase_names_overrides.json. These will have higher priority and will be used instead. You can define as much "aliases" for an item ID as you wish.
Step-by-step: 1. Go to Module:Item/item_ids_by_item_lowercase_names_overrides.json.
2. Add a new line. Follow format: "<item lowercase name>": "<item ID>". Please note, that all items names defined here must be lowercase.
"emag": "EmagUnlimited"3. Save the file.
How to add a link to item?
To make {{item}} behave like a link all the time, a page link needs to be established in Module:Item/item page links by item ids.json. Please note, if you need a one-time link, use the link parameter in the {{item}} template.
1. Go to Module:Item/item_ids_by_item_lowercase_names_overrides.json.
2. Add a new line. Follow format: "<item ID>": "<page name>".
"Protolathe": "Research_and_Development#Protolathe"3. Save the file.
