Fetching inventory item catalog after initialization

Hi mikko_to,

To retrieve a list of catalog items from the catalog you have the

GameFoundation.catalog.GetItems

method. You also have a

GameFoundation.catalog.FindItems

if you want to filter the items.

Here are some snippet to showcase how to use them:

Code (CSharp):

1. void NoFilter()
2. {
3.     // You can use any type of catalog item for this list.
4.     List<InventoryItemDefinition> itemDefinitions = new List<InventoryItemDefinition>();
5.     GameFoundationSdk.catalog.GetItems(itemDefinitions);
6.  
7.     foreach (InventoryItemDefinition definition in itemDefinitions)
8.     {
9.         // Process your definition here ...
10.     }
11. }
12.  
13. void TagFilter()
14. {
15.     const string tagKey = "myTag";
16.  
17.     // You can use any type of catalog item for this list.
18.     List<InventoryItemDefinition> itemDefinitions = new List<InventoryItemDefinition>();
19.     Tag tag = GameFoundationSdk.tags.Find(tagKey);
20.     GameFoundationSdk.catalog.FindItems(tag, itemDefinitions);
21.  
22.     foreach (InventoryItemDefinition definition in itemDefinitions)
23.     {
24.         // Process your definition here ...
25.     }
26. }
27.  
28. void ComplexFilter()
29. {
30.     const string propertyKey = "myProperty";
31.  
32.     // You can only use CatalogItem for this list.
33.     List<CatalogItem> itemDefinitions = new List<CatalogItem>();
34.     GameFoundationSdk.catalog.FindItems(
35.         catalogItem => catalogItem is InventoryItemDefinition definition
36.             && definition.HasMutableProperty(propertyKey),
37.         itemDefinitions);
38.  
39.     foreach (CatalogItem catalogItem in itemDefinitions)
40.     {
41.         // Process your catalog item here ...
42.     }
43. }
44.  

I hope this answered your question.

Thank you ! I hope Game Foundation will help you make a great game.

 

Do you want to search just by key, or by key+value? Is this a case where tags wouldn't be a good fit?

 

There's not currently a method for finding by static properties, but you can use a predicate function to find inventory items.

Code (CSharp):

1. // find all my "type=apparel" inventory items
2. var collectionToPopulate = new List<InventoryItem>();
3. GameFoundationSdk.inventory.FindItems(
4.     item =>
5.     {
6.         item.definition.TryGetStaticProperty("type", out var typeStaticProperty);
7.         return typeStaticProperty.AsString() == "apparel";
8.     },
9.     collectionToPopulate);

edit: I had this as "find all my tier 2 items", but then I saw your video where tier was a mutable property - just to be clear that this snippet is about searching by static properties

 

Hmm, it looks like it's trying to call the wrong method signature for some reason. You might try declaring the lambda function as a variable to pass into FindItems.

We'll look into a way we can prevent this from happening.
