Is there anyway for an enemy to move around a wall

I've been having trouble trying to figure this out. Any help please?

Are you referring to enemy AI?

it can be done quite quickly if you understand this algorithm, as it gives the next position at any point at any speed;

a bit of a natural extension over "just" finding the normal angle, the position it deduces is also an a-priori compatible next position.
