With BindAxis, you are binding per axis, so you need a MouseMoveUp, and MouseMoveRight. You should get a float for any input passed into that function. I’m not sure on the exact setup of bindvectoraxis as I don’t use it in my projects… It is made for things with a vector type input like pen tilt for instance.
Your input component setup looks correct, but I would setup 1D axis bindings for X and Y.
