public function GetPixel(x: int, y: int): Color;
public Color GetPixel(int x, int y);
public def GetPixel(x as int, y as int) as Color

Description

座標(x,y)のピクセルのカラーを取得します

ピクセル座標が境界を超えた場合(width/height よりも大きく、または0より小さく)、 テクスチャのラップモードに基づいてクランプされるかリピートされます。 もしテクスチャから大きなピクセルのかたまりを読み込む場合、 ピクセルカラーのかたまりのすべてを返す.GetPixelsを使う方が早いでしょう。 テクスチャはインポートセッティングのRead/Write Enabledフラグを設定しなくてはいけません。でなければこのファンクションは失敗するでしょう。 See Also: GetPixels, SetPixel, GetPixelBilinear.
