Hey !
You’re right with 2 Years experience it is a lot easier to work with UE4 
I work 8 hrs/day with the Engine to learn exact that tutorial what you mean btw 
I’ll do what you say and learn from the Shooter Tutorial to learn the “basic function” about this.
Btw did you have a solution to this video down below ?https://.com/watch?v=Zm62kqigNpU(I think I need Pitch and a Yaw then replicate the variables)
Thank’s for all your help and tips you’re providing me ! :o
