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. WitrynaJump Point Search: 又名跳点算法，是在保留A*算法框架的同时，进一步优化了A*算法寻找后继节点的操作。A*是寻找所有当前点的邻居，会有频繁的点集合加入和删除到点集合操作，JPS的优点就是会根据当前点的方向以及当前点周围邻居的特点进行选择某些特殊的点才执行加入和删除到点集合操作。
