Component properties in details panel

Hi,

I know that question is old, but that might help someone.

To make an actor’s CPP component editable in blueprints in Unreal Engine 4:

  • The key is to use “VisibleAnywhere”, and optionally “BlueprintReadOnly” in the UProperty meta so the editor displays them correctly. (IE: the movement component in the Character class)
  • This way you can have both a default object configuration AND editor customization via blueprints.
  • To add components at runtime, see this discussion.

Example code for a box component, in your actor class header:

public: 
	UPROPERTY(VisibleAnywhere, BlueprintReadOnly)
	UBoxComponent* MyBox;

In your actor class constructor:

MyBox = CreateDefaultSubobject<UBoxComponent>(TEXT("MyBox"));
MyBox->SetupAttachment(GetRootComponent());
