Tips & Tricks

CallInEditor functions

CallInEditor functions are supported which means you can make a clickable button in details view that will execute a function in editor.

UCLASS()
class UMySubsystem : public UWorldSubsystem
{
   GENERATED_BODY()
public:
   UFUNCTION(CallInEditor, Category=Debug)
   void DrawDebugInfo() { /* implement something */ }
}

Config Export

If your subsystem class has Config and DefaultConfig specifiers you can export their data into associated ini file by using Export to Defaults context menu action.

With only Config flag you can export ini section to clipboard by using Export Modified or Export All context menu actions.

UCLASS(Config=Game, DefaultConfig)
class UMySubsystem : public UWorldSubsystem
{
   GENERATED_BODY()
public:
   UPROPERTY(Config, BlueprintReadOnly)
   int32 NumActorsToSpawn = 0;
   UPROPERTY(Config, BlueprintReadOnly)
   TSoftClasPtr<AActor> ActorClassToSpawn;
}

Notes

Release packages are always updated to latest marketplace release version
