単色三角形サンプル
- 新規でGameObjectを作成しCanvasに追加(ここではRObject)
- ヒエラルキーに新規でMaterial(ここではBlueMaterial)を作りUnlit/Colorを選択し色を選択。
- RObjectにPlaySceneRObject.csをつぶける
- Robjectを選択し、プロパティにあるblueMaterialにBlueMaterialをドラッグ
PlayScene.cs
GameObject rObject = GameObject.Find("RObject");
var mesh = new Mesh();
mesh.vertices = new Vector3[] {
new Vector3 (0, 1f),
new Vector3 (1f, -1f),
new Vector3 (-1f, -1f),
};
mesh.triangles = new int[] {
0, 1, 2
};
mesh.RecalculateNormals();
MeshFilter filter = rObject.GetComponent<MeshFilter>();
filter.sharedMesh = mesh;
MeshRenderer renderer = rObject.GetComponent<MeshRenderer>();
renderer.material = rObject.GetComponent<PlaySceneRObject>().redMaterial;
filter.sharedMesh = mesh;
PlaySceneRObject.cs
public class PlaySceneRObject : MonoBehaviour
{
public Material blackMaterial;
public Material blueMaterial;
public Material greenMaterial;
public Material orangeMaterial;
public Material pinkMaterial;
public Material purpleMaterial;
public Material redMaterial;
public Material whiteMaterial;
public Material yellowMaterial;
}

座標
xとyが正の場合は右上に向かって伸びる
mesh.vertices = new Vector3[] {
new Vector3 (0f, 0f),
new Vector3 (1f, 1.1f),
new Vector3 (1f, 1f),
};
