Hello all, How to create a cube in scene with Blueprint or C++ ?
Hello, 袁涛
First thing you need to implement this in C++ is to declare an appropriate field in your class, which will look something like this:
UPROPERTY()
TSubobjectPtr<UBoxComponent> Cube;
After this, please don’t forget to initialize your cube in constructor of the class and configure in needed way:
Cube = ObjectInitializer.CreateDefaultSubobject<USkeletalMeshComponent>(this, TEXT("Cube"));
Cube->bHiddenInGame = false;
RootComponent = Cube;
Finally, you spawn the cube:
GetWorld()->SpawnActor(ACube::StaticClass());
Please note, that ACube should be replaced with the name of your Cube class.
If you like to learn how to do this using Blueprints, this tutorial should help you:

Hope this helped!
If you just want to spawn a Cube mesh in a level then in blueprint you can do:
- “SpawnActorFromClass” node
- Assign it the Class “StaticMeshActor”
- Plug a make transform node into the SpawnTransform property
- Plug the return value into a SetMesh function of its StaticMeshComponent
- Set the NewMesh property to a cube mesh. Several come with the Engine content
Thank you, it really helped.
I tried this as this seems to be the easiest to test. I added a key event as a trigger to the Spawn Actor. However, I keep getting “Warning Mobility of StaticMeshActor_24 : StaticMeshComponent0 has to be ‘Movable’ if you’d like to move.”, and no cube was spawned
