ジャイロスコープを使用してゲームを作成しようとしていますが、非常に奇妙な問題に直面しています。次の2つのシーンがあります

最初のシーンでボールがドアにぶつかったときに、2 番目のシーンに移動したいです。ボールがゆっくりと動いてドアに衝突すると、すべてが正常に機能し、次のシーンが正常に開始されますが、最初のシーンのボールが非常に速く移動し、大きな力でドアに衝突すると、次のシーンが霜で覆われ始めます。イベントはトリガーされません。何か案が？

2 番目のファイルには、不気味な何かがあるに違いない

function nextScene()
    storyboard.gotoScene( "menu", "fade", 1000 )
end

local function onCollision( event )
    if ( event.phase == "ended" ) then
       if(event.object1.name=="exitscn" or event.object2.name=="exitscn") then
            timer.performWithDelay ( 500, nextScene )
        end 
    end

end

最初に 500 ミリ秒遅らせてから、さらに 1000 ミリ秒遅らせて次のシーンへの移行を遅らせます。ご存知かもしれませんが、最初のファイルと同じ方法でこの遷移を処理していません。

コードは適切だと思います。ストーリーボード シーンのエンター シーンとメモリ リロードで物事をグループ化する際に問題があります。以下の解決策を試してください。

  1. シーンの作成でコード全体を記述したと思いますが、これはストーリーボード シーンに対して 1 回呼び出されます。enterScene に再利用可能なコードを実装するようにし、シーン オブジェクトに入るには local group = self.view を使用する必要があります。

  2. ボールとの DOOR 衝突時、または現在のストーリーボードの終了シーンから、現在のストーリーボード シーンのメモリを更新または解放する必要があります。
