Hi Brandon,
The reason that this isn’t working is because the GetActorLocation node is setting the location of Self, which is the Default Scene Root. If you swap the Default Scene Root for something that you can see (like a Billboard or StaticMesh component) you will see that the it does move how you are telling it too.
To fix this, you can either set the Cube as the root which will work with your original setup.
Or make a direct reference to the Cube.
If you have any other questions just let me know.
Cheers,
TJ
