#### Creating items
16
+
17
+
Ideally `Item`s should be preconfigured and packed into an [`AssetBundle`](https://docs.unity3d.com/Manual/AssetBundlesIntro.html), but you can also construct them at runtime if its easier.
18
+
19
+
Custom `Item`s should have their `persistentID`, `price`, `purchasable`, `Category`, and `icon` properties set to work.
20
+
21
+
If you would like your item to have a chance to be randomly spawned in the Old World like other items, set `spawnable` to `true`, and `itemType` to `Item.ItemType.Tool`.

### Registering items

Use the `RegisterItem` method to register an `Item` to the shop. Ideally the item instance is preconfigured and loaded from an AssetBundle, but you can also construct it during runtime.

Make sure to set the `persistentID`, `price`, `purchasable`, `Category`, and `icon` properties at the very least to ensure the item will show up correctly in the store.

Items can be registered via the `RegisterItem` method:
> Item prices are automatically synchronised between players on lobby join. The price set by the lobby's host will be used for the entire lobby. Once a lobby has been created, the price of a registered item can be updated via `UpdateItemPrice`.

The `SynchronisedMetadata<T>` class allows you to synchronise arbitrary settings between players through the use of [Steam Lobby Metadata](https://partner.steamgames.com/doc/features/multiplayer/matchmaking#6) keys. Simply create a new instance with a specific type and key and it will be automatically updated whenever the key's value is changed.

To update the value, call `SetValue(T value)`. Only the lobby's host may update the value of a key, so the method returns a boolean indicating if the set was allowed. If it was rejected, the instance's value isn't updated. Use the `CanSet` method to check if the current player has permission to update the setting.

When a key is successfully updated either locally or remotely, the `ValueChanged` event will be raised with the new value. Since instances are valid for the lifetime of the game, this event can also be safely used anywhere in your plugin.

In the scenario that you have separate player and lobby settings, and you want to apply the local player's settings when they host a new lobby, make sure to subscribe to the `LobbyHosted` event and overwrite the current value. This ensures that any values set by a previous lobby will be replaced with your player's settings:

Use the `ShopLocalisation` class to add localised strings to your items. Each string is represented as a key-value pair assigned to a specific locale. For built in strings such as display name and tooltips, the item's unity object name (filename) is used or prefixed. For example to localise the Item"Spookbox" the key would be simply also "Spookbox".

## Compatibility

This mod patches `ItemInstanceData`'s `GetEntryIdentifier` and `GetEntryType` methods which may cause issues with other mods that do the same. The library exposes a property to help avoid these issues, which can be read without requiring this mod as a dependency. See the repository's [compatibility](https://github.com/Xerren09/ContentWarningShopAPI/#compatibility) section for more information.

This mod patches `ItemInstanceData`'s `GetEntryIdentifier` and `GetEntryType` methods which are used by the game to serialise and deserialise items when synchronising state between players. Unfortunately, the IDs are hardcoded and there is no way to "reserve" one for a specific type, which means two mods patching these same methods can interpret the same values as their own entries incorrectly. To avoid most (hopefully all) collisions like this, entry IDs used by this mod are counted backwards, from `byte.MaxValue`. However, just to be safe the `Shop` class exposes a `MaxUsedEntryID` property that returns the lowest entry ID it uses, above which all other IDs are reserved.
109
+
110
+
> **WARNING:**
111
+
> `MaxUsedEntryID` will not be accurate until all other mods have initialised and registered their items. Try to check for this value as late as possible, after all other mods are loaded.

Obviously if you aren't already using this mod, you don't want to require it just for this; use this snippet to check if this mod is in use and attempt to fetch this value as a "soft" dependency:
