アニメーション
パラメータがシングルリンク(l_fcv)の場合は、パラメータ ファンクション
カーブにキーを設定します。パラメータがマルチリンク(l_interp)またはオブジェクトの方向リンク(l_interpOri)の場合は、補間オブジェクトに相対値のセットを設定します。
パラメータを複数の駆動パラメータまたはオブジェクトの方向にリンクするとき、補間オブジェクトが作成されます。
このオブジェクトは、相対値のセットへのアクセスおよび保存に使用されます。
A が B とシングルリンクしている場合は、B の値が変化していくとともに A の値をアニメートするリンク ファンクション
カーブが存在します。 このファンクション カーブでは、Y 軸は A の値を示し、X 軸は B
の値を示します。「SetRelativeValues "A"」は、A と B の現在の値を使用して、このファンクション
カーブにキーを設定します。
