U

This page is dedicated for describing the xor.util.ds.U

---

U is a immutable data-structure library, where U stands for both Util and Universal.

With U, you can write code just like this:

Vec dis = displacement(bot.pos(), enemy.pos());
dis = rotate(dis, radians(PI / 2));
Point projected = project(bot.pos(), dis);

Or even this:

Vec dis = displacement(bot.pos(), enemy.pos());
double latVel = cross(dis, enemy.vel());
double advVel = -dot(dis, enemy.vel());
