Why am I unable to move an object in the video?

Smallee thank you for your interest. However, the thing you mention does not make sense because SetWorldLocation is just a method. There is no explicit dependency within InputAxis and SetWorldLocation. Actually there should not be.

Additional, I change the input from axis to action. Still nothing.

Note: SetWorldLocation works fine. I have tested it by changing the input event to just a tick event.
