Then there is the next path with the lowest F value Then the path with the lowest F value is still selected Then turn to find the path with the lowest F value before, but then the F value is higher Then, the path with the smallest H value is preferred, that is, the path closest to the target pointīut after the movement, the F value becomes larger What if there are obstacles between a and B? In this way, the shortest path from point a to point B is found Put the node into the list (array is also OK), set a as the parent node of the node, and then calculate the distance between the surrounding boxesīecause it moves from point a, it will not compare point a in the next comparisonĬalculate again that the node with the smallest F value is still the node in the upper left corner Then, it is calculated that the box in the upper left corner of point a has the smallest F value. Here, let the distance between each two adjacent nodes be 10, then the diagonal distance is 14 Then first calculate the three values of all nodes around the starting point The cost here can adopt straight-line distance or Manhattan distance, as long as it is suitable Hcost: cost (distance) from the target point Gcost: cost from the starting point ( distance) Here, three values are defined for each map node If there are two points a and B on the map, set a as the starting point and B as the target point (end point)
