unity代码创建一个细分数为10的球体

您可以使用以下代码在Unity中创建一个细分数为10的球体：

using UnityEngine;

public class SphereCreator : MonoBehaviour
{
    public int subdivisions = 10;

    void Start()
    {
        GameObject sphere = GameObject.CreatePrimitive(PrimitiveType.Sphere);
        sphere.transform.position = Vector3.zero;
        sphere.GetComponent<MeshFilter>().mesh = CreateSphere(subdivisions);
    }

    Mesh CreateSphere(int subdivisions)
    {
        Mesh mesh = new Mesh();

        // Create vertices
        Vector3[] vertices = new Vector3[12 * subdivisions * subdivisions];
        int vertexIndex = 0;
        float radius = 1f;
        for (int y = 0; y < subdivisions; y++)
        {
            for (int x = 0; x < subdivisions * 2; x++)
            {
                float angleX = x * Mathf.PI / subdivisions;
                float angleY = y * Mathf.PI / subdivisions;
                float sinX = Mathf.Sin(angleX);
                float sinY = Mathf.Sin(angleY);
                float cosX = Mathf.Cos(angleX);
                float cosY = Mathf.Cos(angleY);

                vertices[vertexIndex++] = new Vector3(sinX * cosY, sinY, cosX * cosY) * radius;
            }
        }

        // Create triangles
        int[] triangles = new int[3 * 20 * subdivisions * subdivisions];
        int triangleIndex = 0;
        for (int y = 0; y < subdivisions; y++)
        {
            for (int x = 0; x < subdivisions * 2; x++)
            {
                int i = x + y * (subdivisions * 2);
                int j = (x + 1) % (subdivisions * 2) + y * (subdivisions * 2);
                int k = x + (y + 1) * (subdivisions * 2);
                int l = (x + 1) % (subdivisions * 2) + (y + 1) * (subdivisions * 2);

                if (y == 0)
                {
                    triangles[triangleIndex++] = i;
                    triangles[triangleIndex++] = l;
                    triangles[triangleIndex++] = j;
                }
                else if (y == subdivisions - 1)
                {
                    triangles[triangleIndex++] = i;
                    triangles[triangleIndex++] = k;
                    triangles[triangleIndex++] = l;
                }
                else
                {
                    triangles[triangleIndex++] = i;
                    triangles[triangleIndex++] = l;
                    triangles[triangleIndex++] = j;
                    triangles[triangleIndex++] = j;
                    triangles[triangleIndex++] = l;
                    triangles[triangleIndex++] = k;
                }
            }
        }

        mesh.vertices = vertices;
        mesh.triangles = triangles;
        mesh.RecalculateNormals();

        return mesh;
    }
}

这个代码会在场景中创建一个球体，并将其细分数设置为10。
