In diesem Artikel wird der Beispielcode von HTML5 mit Ihnen geteilt, der Taobao und JD.com imitiert, um den Regeneffekt mit roten Umschlägen zu erzielen. Es hat einen gewissen Referenzwert. Freunde in Not können sich darauf beziehen. Ich hoffe, es wird Ihnen hilfreich sein.
Dieses Red-Envelope-Regenprojekt basiert auf dem HTML5-Spielframework Phaser. Das Endprodukt ist eine Leinwand, daher ist die Leistung sehr gut, aber es muss gesagt werden, dass dieses Framework relativ groß ist, und das ist es auch ca. 700K nach der Komprimierung, daher bitte mit Vorsicht verwenden.
Codeadresse: https://github.com/AmosXu/red-packet-rain
Die Bilder sind die Countdown-Seite, die Seite zum Greifen des roten Umschlags, die Seite zum Öffnen des roten Umschlags und die Seite zum Anzeigen des roten Umschlags in einer Leinwand, ohne Aktualisierungswechseleffekt und super Leistung
