When I press w, up key, or down key, the events do not fire or active and therefore no actions take place. Does anyone know how to fix this? Thank you!
Hey Double_G,
If you are using a custom PlayerController and/or Character, you need to check in the default settings of those blueprints and make sure Block Input is not enabled. Aside from that, you need to use an Enable Input node in this Level blueprint–the easiest way to set it up is to have it connected to a Begin Play event node.
Hope this helps!
That Fixed it! I had to call the enable input node at the start of the game and connect it to "get Player Controller "
