Unity为立方体生成网格

Question

对不起， 最近，我尝试制作一款类似于Minecraft的游戏。

并且在地形的生成过程中遇到了一些问题。

我已经尝试更改一些坐标，没有运气。

for (int x = 0; x < Chunk.size.x; x++)
    {
        for (int y = 0; y < Chunk.size.y; y++)
        {
            for (int z = 0; z < Chunk.size.z; z++)
            {
                // Check if 0 (transparent), skip
                if (faces[index] == 0)
                {
                    index++;
                    continue;
                }

                // Generate face toward North
                if ((faces[index] & (byte)Direction.North) != 0 )
                {
                    // Points on face toward the North
                    vertices[vertexIndex] = new Vector3(x + position.x, y + position.y, z + position.z + 1);
                    vertices[vertexIndex + 1] = new Vector3(x + position.x + 1, y + position.y, z + position.z + 1);

                index++;
            }
        }
    }

我有这个，

我根本无法获得顶部网格，是坐标错误还是其他问题？

当我注释掉Perlin Noise时，可以像这样正确显示。

谢谢您的帮助。
