I have 2 UENUM enumerated types: EGameResource and EGameResourceTypes. UFUNCTION( BlueprintCallable, Category=MyGame) void DefineResourceTypes( TArray<EGameResource> & Resources, EGameResourceTypes ResourceType ); The compiler sadly informs me that OCResourceConversionDefinitions.h(26): error C26…

If you add const in front of your reference type parameter it will make it an input on the blueprint: void DefineResourceTypes( const TArray > & Resources, EGameResourceTypes ResourceType ); By default, pass by reference parameters are treated as outputs on blueprint nodes.

What's the trick to defining an array param in a UFUNCTION?

If you want the array to remain editable, try the UPARAM(ref)
