Get direction to fire at a player's predicted position

clearly my knowledge of physics is subpar. how can I find the direction of u given 0, 1, v and u.Magnitude?


my guess was just (1 - 0).Unit * u.Magnitude + v, but that didn’t seem to work.

edit: v and u are speeds, not distances

I’m not that good at this either but i think my approach would be first getting the position of the 3rd circle and then substract it to 0, so: origin - endPosition = direction. I’m not sure about this but it’s worth a try (please let me know when you solve it, I’m curious)

yeah the issue is I don’t know exactly where the third circle will be, because I don’t know how long it will take before the projectile hits the target
