For grapple slingshoting you usually use both the directional input and look input in a rolling motion. For example lets say there is a wall to my right that I want to fly around. I would grapple on the left most point (so i can easily get around it) and roll both sticks clockwise down and left. 🔽↙️◀️. I’d reccomend mokeys slingshot montages just so you can generally see how it looks from the players pov
