Editor: Input Events

Description

Only in blueprints inherited by the Actor class (which includes your level blueprint). If you have a read at Unreal Engine’s architecture, its input system favours more a event-based design, rather than through conditional statements. All user/local-based input is handled by the Player Controller class and Player Input class.

Make sure you select Class Defaults in the blueprint’s toolbar, hop over to the Input category in the details panel and AutoReceiveInput select Player 0:
