WPF/IronPythonで、Silverlightアニメーション(お掃除ロボット)を実行できるようにする。
ネットを検索していると、このSilverlightプログラムが目にとまった。
さっそく、IronPythonで、動かすことにした。少しアレンジしています。
デザインツールで始めるSilverlightアニメ／グラフィック
Silverlight 2で.NET技術をカッコよく使おう（3）

フローリングの好きな位置をクリックすると、Xamloomba君がその方向に回転した後に目的地まで移動します。
この処理はStoryboardを動的に生成して実行して実現していますので、詳しくはソースを確認してください .…
