First of all, I don't know if "drag" is the correct term in this case, my english is not that good.
I'm trying to make a 2d top-down "Free kick" soccer game (see New Star Soccer). Where depending where you hit/kick the ball will determine the angle and force applied to the ball, including drag or effect on it, it's time on the air, etc.
You can (more or less) see what I'm talking about in this video
I've tried using different approaches but none of them feels right. I'm about to test using freel fall equations on y axis to calculate the flight time of the ball given certain force and angle, but the problem is the effect on the ball, I've been thinking about using the same free fall equations but with a different gravity (much smaller than 9.8). Haven't tested this.
I've tried using sin behavior to a certain value, so it goes up and continues to go down until the ball stops, but it just doesn't feel right. I think theres the qarp interpolation to simulate something like this, but don't really know how to use it, because in the examples I've seen (all by R0j0) he's using another set of x,y positions.
I could keep writing about all the ways I can think of making it work, but maybe I'm just too focused on the problem right now that I can't just see a clearer path to tackle this.
Anyways, hope you cguys can help.
