ここで質問して問題点を理解し、解決出来たと思ったのですが、動かしているうちに全然解決できていないことが判明してしまいました
ある敵機は正面からは攻撃を受け付けず裏側に回り込まなければならない。みたいな事をやりたいのですが・・・
内容は俯瞰目線のシューティングで敵機や自機の向いている方向は状況によって３６０°変化します
あと自機の画像と弾丸の画像は↑方向で敵機は↓を向いています。
ＶＣ＋＋２００８ ＤＸライブラリを使用していて ＯＳは７です
とりあえず問題に直接関係ありそうな関数を載せます。
問題の判定部分は huntei です
弾の角度はattackで代入されます
敵の角度はenemy自機はmoveです
