So, I made a lot of progress the other day with the addition of Simple PathFinding 2dโ€ฆ Iโ€™m successfully drawing debug paths that conform to my hexgrid. The next step is figuring out how to grab a list of Vector3Ints for grid locations along a path and then turn them to world positions with CellToWorld and then step through them one at a time (each piece has a range var that represents how many spaces they can move each turn).

I see a function in the Simple PathFinding 2d API called GetPathPointList() that should give me a list of Vector3Ints, but I seem to be using it incorrectly:

void Update()
        if (GameController.CurrentState == GameState.PlayerTurn && isPlayer == true)
            Vector3 position = transform.position;
            Vector3Int cellPosition = grid.WorldToCell(transform.position);
            Vector3 mouseWorldPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
            mouseWorldPos.z = 0.0f;

            if (Input.GetMouseButtonDown(0))

                Vector3Int coordinate = grid.WorldToCell(mouseWorldPos); 
                //get a hex cell coordinate from a mouse click
                Debug.Log("piece position: " + cellPosition);
                Debug.Log("destination: " + coordinate);
                path.CreatePath(position, mouseWorldPos);

            if (path.IsGenerated())
                List<Vector3Int> CellPath = path.GetPathPointList(); 
                //how do we use "pathpoints" from the API?
                //Debug.Log("Path: " + CellPath); 
                // I guess getpathpointlist isn't it? 
                //this says "Path: System.Collections.Generic.List`1[UnityEngine.
                //List<Vector3> WorldCoords = grid.CellToWorld(CellPath); 
                //how do I convert a list of vec3ints to a list of vec3's? this isn't 
                //doing it.

                // start a coroutine which animates the object along a path

    public IEnumerator FollowPath(List<Vector3> WorldCoords)
        //  for Coordinate in WorldCoords {
        //  	transform.position = Coordinate
        //  	wait a sec }

Hi Wiley,

The GetPathPointList() function returns a list of tile coordinates that make up the path. You can use something like GetPathPointWorld() to get the world position of a particular path point. If you use GetPathPointWorld(n) it will return the world position of the nth tile in that path.

Hopefully that helps. If it doesnโ€™t let me know!
