Need Assistance

Hey there I’m having major issues with my code and was looking for someone who could possibly have a look at my blueprinting and tell me where I’m going wrong. It’s still really basic stuff and I’ll post screenshots below.

I’m trying to get the tube to spawn an instance of the triangle moving in a single direction when I press f or the left mouse button, but it’s not even receiving the f or mouse pressed when I run it. The triangles velocity works fine by itself.

That’s exactly what I’m following but I don’t have a player controller for some reason? I’m running 4.2.1 or did I miss something?
