一、首先當然得有至少有二個場景sceneA.js,sceneB.js

二、從場景A傳值到場景B二種方法

1)通過事件this.events.emit("event key",{objKey:objValue});

從sceneA通過 ths.events.emit時傳值到sceneB時有個需要特別注的事項就是，得把sceneB的 active設為 ture,否則因為 sceneB還未激活，是監聽不到 events.on事件的!!!

2)通過場景啟動this.scene.start("gameB key",{objKey:objValue});

具體詳見代碼：

結語： 用Phaserjs3 JavaScript框架 來開發HTML網頁游戲，雖不復雜，但有道是『紙上得來終覺淺，絕知此事要躬行』，代碼還是得親自多碼才行噢！
