first question here.
I ran into a problem where my math skills are just not enough, probably it's simple, but I don't know how to approach it.
I'll show you this graphic so you can understand what I need to find:
The green line represents the movement of an unit in a videogame I'm developing, the idea is that the unit can accelerate until it reaches the proper angle, then it advances in a straight line and then "parks the car".
Programatically speaking, I need to know the value of the ß angle before I even start moving the unit, then it's just a mirror, no problem from there.
Do you guys have an idea of how to find such angle based on what I've showed you?.
Stop rotating when $\frac{midpoint.x-obj.x}{midpoint.y-obj.y}\approx\tan( unit.rotation)$
