Implementing this successfully can be a nightmare.

Yeah, Diamond's Melee movement just precise predicts 5 ticks out and discards any movement option that hits a wall. It looks butter smooth and I love watching it.

But I once tried augmenting my existing 1v1 wall smoothing with this trick. In the end, the code was horribly ugly, I never hit a wall, and I didn't gain any points from it. Kind of killed my spirit to find points in improved wall smoothing. (And I removed it.)

And really, sometimes maximizing escape angle means slamming into the wall at full speed. If it means dodging a bullet it's still the right move.
