Servus Miteinander,
ich habe hier einen Codeschnipsel, der eine Sounddatei läd und abspielt. So weit, so gut. Ich möchte diese Klasse nun mit einem Vector so erweitern, dass ich möglichst viele AudioClips hintereinander laden kann, denen einen Namen geben kann und schließlich mit Methoden Play und Stop diese auch unabhängig starten und stoppen kann. Wie würdet ihr da vorgehen?
Lieben Gruß
Richard
