问题 My actual code: function Update() { if(Input.GetMouseButtonDown(0)) { Debug.Log("foto"); Application.CaptureScreenshot(Application.dataPath + "Screenshot.png"); } } I need the path for the output of every photo for this function.

Also, don't forget to join the path and the folder name with a forward slash: Application.CaptureScreenshot

I am aware of the function get_all_shortest_paths , which is for shortest paths, but could not find a general one. Update: My main goal is to get all nodes in these paths, so that I can then get a subgraph of these nodes. 回答1: Since you mentioned in your question that your ultimate goal is to get only the nodes that are in these paths and not the paths themselves, I think you don't even
