Resources Subsystem

The resources subsystem can be used to get information about all resource types registered in your project.

Subsystem Methods

Get Subsystem

This method uses a cached pointer to the subsystem, which will be much faster than the regular blueprint node.

static USimpleResourcesSubsystem* GetPtr();

USimpleResourcesSubsystem* Subsystem = USimpleResourcesSubsystem::GetPtr();

USimpleResourcesSubsystem& Subsystem = USimpleResourcesSubsystem::Get();

Get All Resource Definitions

        static void GetAllDefinitions(
          TArray<USimpleResourceDefinition*>& OutResources
        );
        

        TArray<USimpleResourceDefinition*> Definitions;
        USimpleResourcesSubsystem::GetAllDefinitions(Definitions);
        

        static TArray<USimpleResourceDefinition*> GetAllDefinitions();
        auto Resources = USimpleResourcesSubsystem::GetAllDefinitions();
        

Get Resource Definitions By Tag

Allows fetching all resources with the specified tag.

Assuming we have some gameplay tag hierarchy like:

Resources
- RawResource
  - Iron
  - Copper
  - Gold
- ProcessedResource
  - IronBar
  - CopperBar
  - GoldBar

If we wanted all of our RawResource type resources, we can use Resources.RawResource as the tag, this would fetch all 3 of them.

If we just used Resources.RawResource.Iron as the tag, it would only fetch the Iron resource.

        static void GetResourceDefinitionsByTag(
          FGameplayTag Tag, 
          TArray<USimpleResourceDefinition*>& OutResources
        );
        

        FGameplayTag Tag = FGameplayTag::RequestGameplayTag(FName(TEXT("Resources.RawResource")));
        TArray<USimpleResourceDefinition*> Definitions;
        USimpleResourcesSubsystem::GetResourceDefinitionsByTag(Tag, Definitions);
        

Get Resource Definition By Tag

Gets a single resource definition by its tag.

        static USimpleResourceDefinition* GetResourceDefinition(
          FGameplayTag Tag
        );
        

        FGameplayTag Tag = FGameplayTag::RequestGameplayTag(FName(TEXT("Resources.RawResource.Iron")));
        USimpleResourceDefinition* Definition = USimpleResourcesSubsystem::GetResourceDefinition(Tag);
        

Try To Get Resource Definition By Tag

Gets a single resource definition by its tag.

        static bool TryGetResourceDefinition(
          FGameplayTag Tag, 
          USimpleResourceDefinition*& OutDefinition
        );
        

        FGameplayTag Tag = FGameplayTag::RequestGameplayTag(FName(TEXT("Resources.RawResource.Iron")));
        USimpleResourceDefinition* Definition = nullptr;
        if(USimpleResourcesSubsystem::TryGetResourceDefinition(Tag, Definition)) {
            // Do something
        }
