unity-网格编程06

既然已经完成了一个三角形的那么我们参照之前的,再写一个三角形,并把这个面片拼凑成一个四边形,那么直接参照之前的代码就好了,还有为了方便看出来,稍微的调整第二个三角形的位置.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

//脚本对于组件的依赖
[RequireComponent(typeof(MeshFilter),typeof(MeshRenderer))]

public class SimpleProceduralMesh : MonoBehaviour
{
    private void OnEnable()
    {

        Mesh mesh = new Mesh()
        {
            name = "Procedural Mesh"
        };

        //3个顶点
        mesh.vertices = new Vector3[] {
            Vector3.zero ,
            Vector3 .right ,
            Vector3 .up ,
            new Vector3 (1.1f,0),
            new Vector3 (1.1f,1.1f),
            new Vector3 (0,1.1f)
        };
        //顶点的渲染顺序
        mesh.triangles = new int[] {
            0,2,1,
            5,4,3
        };
        //模型发现朝向
        mesh.normals = new Vector3[] {
            Vector3 .back,
            Vector3 .back,
            Vector3 .back,
            Vector3 .back,
            Vector3 .back,
            Vector3 .back

        };
        //模型UV
        mesh.uv = new Vector2[] {
            Vector2 .zero,
            Vector2.right,
            Vector2.up ,
            new Vector3 (1.1f,0),
            new Vector3 (1.1f,1.1f),
            new Vector3 (0,1.1f)
        };

        mesh.tangents = new Vector4[] {
            new Vector4(1f,0f,0f,-1f),
            new Vector4(1f,0f,0f,-1f),
            new Vector4(1f,0f,0f,-1f),
            new Vector4(1f,0f,0f,-1f),
            new Vector4(1f,0f,0f,-1f),
            new Vector4(1f,0f,0f,-1f)
        };

        GetComponent<MeshFilter>().mesh = mesh;
        
    }

    
}

那么再次运行unity程序:
