Floating Windowをボタンにしないなんてもったいない！
Floating Windowを使って立体的なボタンを作ってみた。ENTERでボタンを押せる。
ボタンに見せるにはどうするか
- frontとbackの2枚のウィンドウを用意
- backの色をfrontの色よりちょっと暗く
- 押されたときにbackを覆い隠すようにfrontの位置を下げる
これでボタンになる。Floating Windowを2枚用意して、ENTERが押されたら位置を下げて戻せば押したように見える。

せっかくなのでENTERで弾を発射できるようにする
ENTERでボタンPUSH＆弾発射
ついでにhjklで移動できるようにもした。

終わり
いまのところ全く実用性はないけど、どこかで使うときが来ると思う。たぶん。
