BushOverwrite.js

If there is a tile above a tile with bush detection that is not bush and does
not have a ★ passability rating,
the bush detection for that square will be disabled.

The same rule applies to damage floor tiles.

This rule prevents bush detection, for example, if a bridge is built over a
bush tile.

@help BushOverwrite.js

茂み判定があるタイルより上のレイヤーに、
茂みでなくかつ通行判定が★でないタイルがある場合、
そのマスの茂み判定を無効とします。

ダメージ床タイルについても同様の仕様が適用されます。

この仕様により、例えば茂みタイルの上に橋が架かっている場合などで
茂みが適用されなくなります。

 作者に無断で改変、再配布が可能で、利用形態（商用、18禁利用等）
 についても制限はありません。
 このプラグインはもうあなたのものです。
