Parsing two different int values from same string

Unity Engine
1

Hi,

I’m slightly confused about how to go about extracting some numbers from a string, I’m not sure if even starting the right way.

I’ve got a grid of cubes that i was trying to get their index x,y co-ords, not position, just their relative x, y index ie 0,0, 8,4 etc.

The way I’ve tried to solve it is by giving them a name using point.name = x + “,” + y; and then try and parse it to get them back to ints, but the examples I’ve seen for parsing don’t use multiple variables, so I’m a bit confused as to whether it’s possible.

Is there a way to remove the comma using parsing and split the x and y into two separate ints?

Is this the best way to go about this? Is there another way of getting the index from a transform array?

using UnityEngine;
using System.Collections;

public class TransformGrid : MonoBehaviour {

    public Transform prefab;

    public int gridResoX = 10;
    public int gridResoY = 10;
    public int gridResoZ = 10;

    private int row;
    private int column;

    private Vector3 lastPosition;

    Transform[] grid;

    void Awake () 
    {
        grid = new Transform[gridResoX * gridResoY];
            for (int i = 0, y = 0; y < gridResoY; y++) {
                for (int x = 0; x < gridResoX; x++) {
                    grid[i] = CreatePoints (x, y);
            }
        }
    }

    void UpdateMouse()
    {
        lastPosition = Input.mousePosition;
    }

    void Update()
    {
        if (Input.mousePosition != lastPosition) {
            RaycastHit hit;
            Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition);
            if (Physics.Raycast (ray, out hit)) {
                if (Input.GetMouseButtonDown (0)) 
                {
                    UpdateMouse();
                    DeletePoints (hit.collider.name);
                    //Debug.Log (hit.collider.name);
                }
            }
        }
    }

    void DeletePoints(string name)
    {
        int num = int.Parse(name);
        Debug.Log (num);
    }

    Transform CreatePoints(int x, int y)
    {
        Transform point = Instantiate<Transform>(prefab);
        point.name = x + "," + y;
        point.parent = transform;
        point.localPosition = GetCoordinates (x, y);

        point.GetComponent<MeshRenderer> ().material.color = new Color 
        (
            (float)x / gridResoX,
            (float)y / gridResoY,
            (float)y / gridResoZ
        );
        return point;
    }

    Vector2  GetCoordinates(int x, int y) {
        return new Vector2 
        (
            x - (gridResoX - 1) * 0.5f,
            y - (gridResoY - 1) * 0.5f
        );
    }
}

There’s something I just found called .Split() and seems like you can remove unicode characters like commas.

Does anyone know how to use Split()??

Or whether there’s a way to take a four digit number and separate it into two two digit numbers? That’s the way I was trying to do it before I saw split, but I have no idea how to use it!

void DeletePoints(string name)
    {
        place = int.Parse(name);
        name.Split ("", 2);
        Debug.Log(place);
    }

    Transform CreatePoints(int x, int y)
    {
        Transform point = Instantiate<Transform>(prefab);
        point.name =  x + "" + 0 + "" + y;
        point.parent = transform;
        point.localPosition = GetCoordinates (x, y);

        point.GetComponent<MeshRenderer> ().material.color = new Color
        (
            (float)x / gridResoX,
            (float)y / gridResoY,
            (float)y / gridResoZ
        );
        return point;
    }
