WitrynaActually, if you look at the definition of 45-degree route, it is always possible to transform a path with 45-degree route into a path without 45-degree turn. And it's also optimal (you can easily prove it by contradiction). So, the simplest way is to run the jump point search and then transform it into orthogonal route.
