Menu Item that Asks for Input

I have been looking around for quite a while and not seen this addressed. Can you make a Menu Item that asks for input? Right now I have a Menu Item Script which works fine, but if I want to change the number of hexes it creates, I have to reopen the file and change the x and y numbers. Is there a way to ask for an x and y value before it generates them?

Here is my code:

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;
3. using UnityEngine.UI;
4. using System.Collections;
5.  
6. public class HexGenerator
7. {
8.  
9.     static int y = 16;//size of the map I want this to be decided when I click the Menu Item
10.     static int x = 16;
11.  
12.     [MenuItem("Hex Board/Generate Tiles")]
13.     static void Create()
14.     {
15.         float Xdist = 1.27f; //The x distance between collumns of tiles IN EVEN NUMBERED ROWS
16.         float Ydist = 0.96f; //The y distance between rows of tiles
17.         GameObject HexBlueprint;
18.         GameObject HexContainer = new GameObject("Hex Container");
19.         Sprite HexImage = new Sprite();//loads the default hex image so it does not need to be loaded everytime for each hex
20.         Texture2D HexPNG = Resources.Load<Texture2D>("Hexes/Base Hex");
21.         HexImage =
22.             Sprite.Create(HexPNG,
23.             new Rect(0, 0, HexPNG.width, HexPNG.height),
24.             new Vector2(0.5f, 0.5f));
25.  
26.         CharacterMovement mapInfo = GameObject.Find("Movement Controler").GetComponent<CharacterMovement>();
27.         mapInfo.maxX = x - 1;//sets the max coordinates so the Movement Controller knows the largest x and y values of the map.
28.         mapInfo.maxY = y - 1;
29.  
30.         for (int i = 0; i < y; i++)
31.         {
32.             for (int j = 0; j < x; j++)
33.             {
34.                 if (i % 2 == 0)
35.                 {
36.                     HexBlueprint = new GameObject("Hex," + j + "," + i);
37.                     HexBlueprint.transform.position = new Vector3(j * Xdist, i * Ydist, 1);//places the tile in position based on the coordinates
38.  
39.                     SpriteRenderer renderer = HexBlueprint.AddComponent<SpriteRenderer>();
40.                     renderer.sprite = HexImage;
41.                     HexBlueprint.transform.parent = HexContainer.transform;//puts hex into easy to collapse container
42.                 }
43.                 else
44.                 {
45.                     HexBlueprint = new GameObject("Hex," + j + "," + i);
46.                     HexBlueprint.transform.position = new Vector3(j * Xdist + Xdist / 2, i * Ydist, 1);//places the tile in position based on the coordinates
47.  
48.                     SpriteRenderer renderer = HexBlueprint.AddComponent<SpriteRenderer>();
49.                     renderer.sprite = HexImage;
50.                     HexBlueprint.transform.parent = HexContainer.transform;//puts hex into easy to collapse container
51.                 }
52.             }
53.         }
54.     }
55. }
