Interacting with Actors MouseOver event? C++

[anonymous_user_8e2766aa]

Hello, Troublesum

To implement MouseOver event, please do the following:

1. In Actor’s header, add these lines:

    //Static Mesh Component to interact with
   

   UPROPERTY(VisibleAnywhere)
   UStaticMeshComponent* CustomMeshComponent;

   //Function to handle the interaction
   

   UFUNCTION()
   void CustomOnBeginMouseOver(UPrimitiveComponent* TouchedComponent);

2. Define the function in Actor’s .cpp file:

   void AMyActor::CustomOnBeginMouseOver(UPrimitiveComponent* TouchedComponent)
   {
   if (GEngine)
   {
   GEngine->AddOnScreenDebugMessage(-1, 3.f, FColor::Cyan, TEXT(“Mouse Over”));
   }
   }

3. Initialize the component and bind the function in Actor’s constructor:

   CustomMeshComponent = CreateDefaultSubobject(TEXT(“Test Component”));
   CustomMeshComponent->AttachTo(RootComponent);
   CustomMeshComponent->OnBeginCursorOver.AddDynamic(this, &AMyActor::CustomOnBeginMouseOver);
   Finally, create a Player Controller to control mouse. (If you like to learn more about creating Player Controller to control mouse, please go here:

This should do it. Please don’t forget to place the Actor into the level and add the Static Mesh asset.

Hope this helped!

Have a great day!
