search ). This is an efficient pathfinding algorithm found in recent years. However, there is a restriction that you can only find the path on the regular grid map, and the vertices or edges on the map cannot carry weights, that is, there cannot be complex terrain, only flat and barrier terrain is supported. The idea is to skip a large number of symmetric paths in a flat area of a rectangle and only search for so-called jump points as search nodes. In this way, a large number of nodes in the re
