彥霖 實驗筆記

要先在外面先建立 "空物件"，然後把以下程式碼拖進去
之後要手動 Add Component，本次需要匯入兩個 Component，分別是 MeshFillter 與 MeshRender
最後在建立一個 Material 把它丟入 MeshRender  (如果有喜歡的圖片也可匯入)

如下：

 

執行結果 (沒意外會出現一個 小蘿莉 平面，大功告成!!)：

 

程式碼：

using UnityEngine;
using System.Collections;

public class MyMesh : MonoBehaviour {

    void Start () {

        MeshFilter mf = GetComponent <MeshFilter>();
        Mesh m = new Mesh ();
        mf.mesh = m;

        Vector3 [] v = new Vector3[4];
        v [0] = new Vector3 (0, 0, 0);
        v [1] = new Vector3 (10, 0, 0);
        v [2] = new Vector3 (0, 10, 0);
        v [3] = new Vector3 (10, 10, 0);

        int [] t = new int[6];
        t [0] = 0;
        t [1] = 2;
        t [2] = 1;
        t [3] = 2;
        t [4] = 3;
        t [5] = 1;

        Vector3 [] n = new Vector3[4];
        n [0] = new Vector3 (0, 0, -1);
        n [1] = new Vector3 (0, 0, -1);
        n [2] = new Vector3 (0, 0, -1);
        n [3] = new Vector3 (0, 0, -1);

        Vector2 [] uv = new Vector2[4];
        uv [0] = new Vector2 (0, 0);
        uv [1] = new Vector2 (1, 0);
        uv [2] = new Vector2 (0, 1);
        uv [3] = new Vector2 (1, 1);

        m.vertices = v;
        m.triangles = t;
        m.normals = n;
        m.uv = uv;

    }

}
