Even though this recipe covers defining a function, please take into consideration the comments in the code for better understanding of the implementation and code flow:
- Define the GetPathAstar function, along with its member variables:
public List<Vertex> GetPathAstar(GameObject srcObj, GameObject dstObj, Heuristic h = null) { if (srcObj == null || dstObj == null) return new List<Vertex>(); if (ReferenceEquals(h, null)) h = EuclidDist; Vertex src = GetNearestVertex(srcObj.transform.position); Vertex dst = GetNearestVertex(dstObj.transform.position); GPWiki.BinaryHeap<Edge> frontier = new GPWiki.BinaryHeap<Edge>(); Edge[] edges; Edge node, child; int size = vertices.Count; float[] distValue = new float[size]; int[] previous ...
