Haha thanks for the sub, I am just trying to understand your issue. So it may not be obvious because I gave you the last video of a 3 part mini tutorial for creating that effect. But the player controls the “pitch” of a projectile the longer you hold down the input key to fire the higher the arc created will be. I may not have demonstrated it well at the end but basically it was a tutorial for creating a grenade toss where the player by holding down a key and changing the “arc” would be able to throw the grenade a short distance or a longer distance. It is basically the image you posted. So I am wondering what I am missing from your question. It is a dynamic “arc”. Although I didn’t make it to shoot below horizontal from the launch point but with a minor tweak you could get that too.
