「Unity/Csharp/mesh」の版間の差分

2020年5月1日 (金) 14:18時点における版

1. 新規でGameObjectを作成しCanvasに追加(ここではRObject)
2. 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。
3. RObjectにPlaySceneRObject.csをつぶける
4. 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;
}
