My procedural grid doesnt genearate on Z axis, please help!

Let's say grid is 10x10, so the grid generates 60 vertices(in one row), 3 for each triangle (so it doesnt make a gradient look), and 2 triangles for each quad. And it generates 10 of them in x axis, but if i put z axis any number more than 1, none of the triangles generate, not even on the x axis. Triangles array doesnt run out of space.
I dont understand the problem, please help!

Here are pictures to help:

This is the code:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. [RequireComponent(typeof(MeshFilter), typeof(MeshRenderer))]
6. public class CustomMesh : MonoBehaviour {
7.  
8.     Mesh mesh;
9.     Vector3[] vertices;
10.     int[] triangles;
11.  
12.     public int xSize;
13.     public int ySize;
14.     public bool gizmos = false;
15.  
16.     void Awake()
17.     {
18.         Generate();
19.     }
20.  
21.     void Generate()
22.     {
23.         GetComponent<MeshFilter>().mesh = mesh = new Mesh();
24.         mesh.name = "Procedural Grid";
25.  
26.         vertices = new Vector3[xSize * ySize * 6];
27.         triangles = new int[xSize * ySize * 6];
28.  
29.         for (int y = 0, i = 0; y < ySize;)
30.         {
31.             for (int x = 0; x < xSize; x++)
32.             {
33.  
34.                 vertices[i] = new Vector3(x, 0, y);
35.                 vertices[i + 1] = new Vector3(x, 0, y + 1);
36.                 vertices[i + 2] = new Vector3(x + 1, 0, y);
37.                 vertices[i + 3] = new Vector3(x, 0, y + 1);
38.                 vertices[i + 4] = new Vector3(x + 1, 0, y + 1);
39.                 vertices[i + 5] = new Vector3(x + 1, 0, y);
40.  
41.                 i += 6;
42.             }
43.             y++;
44.         }
45.  
46.         mesh.vertices = vertices;
47.  
48.         for(int y = 0, ti = 0; y < ySize;)
49.         {
50.             for(int x = 0; x < xSize;)
51.             {
52.                 triangles[ti] = ti;
53.                 triangles[ti + 1] = (ti + 1);
54.                 triangles[ti + 2] = (ti + 2);
55.                 triangles[ti + 3] = (ti + 3);
56.                 triangles[ti + 4] = (ti + 4);
57.                 triangles[ti + 5] = (ti + 5);
58.  
59.                 ti += 6;
60.                 x++;
61.             }
62.             ti += 6;
63.             y++;
64.         }
65.      
66.         mesh.triangles = triangles;
67.         mesh.RecalculateNormals();
68.     }
69.  
70.     private void OnDrawGizmos()
71.     {
72.         if (gizmos == true)
73.         {
74.             Gizmos.color = Color.black;
75.             for (int i = 0; i < vertices.Length; i++)
76.             {
77.                 Gizmos.DrawSphere(vertices[i], 0.1f);
78.             }
79.  
80.             if (vertices == null)
81.             {
82.                 return;
83.             }
84.         }
85.     }
86. }

 

The problem is the second "ti += 6", in line 62. Remove that and it works!

 

Seriously dude you're a life saver, thank you

 

Sharp as a tack!
