Stuck on Blueprint Quickstart Tutorial (Nested Matinee's and Arrow Components)

Hello,

I am currently stuck on the last 2 steps of the blueprint quickstart tutorial that ask me to:

Apply an arrow component to a class blueprint that determines which direction the player launches.I just don’t understand this and don’t see any guides anywhere on how to do it.

Play an animation when I step on the launchpad (I have this working in the level blueprint, but I would like to nest it in the class blueprint for the launchpad in order to keep things clean and the launchpad behavior consistent)

Forgive the spaghetti, here’s the quick start guide for ref - https://docs.unrealengine.com/latest/INT/Engine/Blueprints/QuickStart/7/index.html
