OpenSiv3D v0.6.4 新規追加・更新サンプル

3D 描画時の UVTransform

Mesh, Box, OrientedBox, Plane の描画関数に TextureRegion を渡せるようになりました。
この機能の追加に伴い、標準頂点シェーダに新しい標準定数バッファが追加されたため、カスタム頂点テクスチャを使用している場合は注意が必要です。

}

Font にリガチャ(合字)を回避するオプションを追加

文字列のグリフ配列を取得する Font のメンバ関数において、リガチャ(合字)の有無を設定できるようにし、Font::getGlyphs() についてはデフォルトで合字を無効化するようにしました。

リガチャに関する参考記事

# include <Siv3D.hpp> // OpenSiv3D v0.6.4

void Draw(const Vec2& basePos, const Array<Glyph>& glyphs)
{
	Vec2 penPos{ basePos };

	for (const auto& glyph : glyphs)
	{
		glyph.texture.draw(Math::Round(penPos + glyph.getOffset()));

		penPos.x += (glyph.xAdvance + 30);
	}
}

void Main()
{
	const Font font{ 40 };

	while (System::Update())
	{
		// v0.6.3 まで(リガチャが有効)
		Draw(Vec2{ 40, 40 }, font.getGlyphs(U"Efficient", Ligature::Yes));

		// v0.6.4(リガチャがデフォルトで無効)
		Draw(Vec2{ 40, 140 }, font.getGlyphs(U"Efficient"));
	}
}

Polygon::addHole() の改良

Polygon::addHole()RectFCircle, Quad などの図形を渡せるオーバーロードを追加しました。また、穴の追加に失敗した場合、自身は変更せずに bool 型の戻り値で false を返すようになりました。

# include <Siv3D.hpp> // OpenSiv3D v0.6.4

void Main()
{
	Polygon polygon = Scene::Rect().stretched(-40).asPolygon();

	while (System::Update())
	{
		const Rect rect{ Arg::center = Cursor::Pos(), 60, 40 };

		if (MouseL.down())
		{
			if (not polygon.addHole(rect))
			{
				Print << U"Failed";
			}
		}

		polygon.draw(ColorF{ 0.8, 0.9, 1.0 });

		rect.draw(ColorF{ 1.0, 0.5 });
	}
}

NavMesh のコンストラクタに地形データを渡し、コンストラクタ内でビルドできるようになりました。ナビメッシュを使うコードを少し短くできます。

# include <Siv3D.hpp> // OpenSiv3D v0.6.4

void Main()
{
	Scene::SetBackground(ColorF{ 0.8, 0.9, 1.0 });

	Polygon polygon = Scene::Rect().stretched(-40).asPolygon();
	polygon.addHole(Rect{ 100, 100, 200, 200 });
	polygon.addHole(Rect{ 200, 350, 150, 100 });
	polygon.addHole(Rect{ 500, 200, 200, 200 });

	const Vec2 start{ 70, 70 };
	NavMesh navMesh{ polygon, NavMeshConfig{ .agentRadius = 10 } };

	while (System::Update())
	{
		polygon.draw();

		const Vec2 goal = Cursor::Pos();
		const LineString lines(navMesh.query(start, goal));

		lines.draw(5, Palette::Red);
		start.asCircle(8).draw(Palette::Red);
		goal.asCircle(8).draw(Palette::Red);
	}
}

-1.0 ~ 1.0 の範囲を返す Periodic 関数

従来の Periodic:: 系の関数は 0.0~1.0 を返しましたが、-1.0~1.0 を返す関数が追加されました。

# include <Siv3D.hpp> // OpenSiv3D v0.6.4

void Main()
{
	Scene::SetBackground(Palette::White);

	while (System::Update())
	{
		const double p0 = Periodic::Square1_1(2s);
		const double p1 = Periodic::Triangle1_1(2s);
		const double p2 = Periodic::Sine1_1(2s);
		const double p3 = Periodic::Sawtooth1_1(2s);
		const double p4 = Periodic::Jump1_1(2s);

		Line{ 100, 0, 100, 600 }.draw(2, ColorF{ 0.8 });
		Line{ 700, 0, 700, 600 }.draw(2, ColorF{ 0.8 });

		Circle{ (400 + p0 * 300), 100, 20 }.draw(ColorF{ 0.25 });
		Circle{ (400 + p1 * 300), 200, 20 }.draw(ColorF{ 0.25 });
		Circle{ (400 + p2 * 300), 300, 20 }.draw(ColorF{ 0.25 });
		Circle{ (400 + p3 * 300), 400, 20 }.draw(ColorF{ 0.25 });
		Circle{ (400 + p4 * 300), 500, 20 }.draw(ColorF{ 0.25 });
	}
}

MeshData::RoundedBox()

角が丸い直方体メッシュデータを作れる MeshData::RoundedBox() を追加しました。

	while (System::Update())

			}
		}

		// RenderTexture を 2D シーンに描画
		{
			Graphics3D::Flush();
			renderTexture.resolve();
			Shader::LinearToScreen(renderTexture);
		}
	}
}

Shader::LinearToScreen() でのテクスチャフィルタ指定を可能に

Shader::LinearToScreen() で 3D 描画結果を 2D シーンにコピーする際に、最近傍補間を使えるようになりました。低解像度風の 3D 映像のレンダリングに役立ちます。

DisjointSet (Union Find)

Script 内で include したファイルを取得する

# include <Siv3D.hpp> // OpenSiv3D v0.6.4

void Main()
{
	const ManagedScript script{ U"example/script/hello.as" };

	Print << script.getIncludedFiles();

	while (System::Update())
	{
		script.run();
	}
}

ManagedScript に、リロードを発生させるカスタムトリガーを設定する

# include <Siv3D.hpp> // OpenSiv3D v0.6.4

void Main()
{
	ManagedScript script{ U"example/script/hello.as" };

	script.setTriggerToReload([](){ return (KeyControl + KeyR).down(); });

	while (System::Update())
	{
		script.run();
	}
}
