一、首先當(dāng)然得有至少有二個(gè)場(chǎng)景sceneA.js,sceneB.js

二、從場(chǎng)景A傳值到場(chǎng)景B二種方法

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

從sceneA通過(guò) ths.events.emit時(shí)傳值到sceneB時(shí)有個(gè)需要特別注的事項(xiàng)就是，得把sceneB的 active設(shè)為 ture,否則因?yàn)?sceneB還未激活，是監(jiān)聽(tīng)不到 events.on事件的!!!

2)通過(guò)場(chǎng)景啟動(dòng)this.scene.start("gameB key",{objKey:objValue});

具體詳見(jiàn)代碼：

結(jié)語(yǔ)： 用Phaserjs3 JavaScript框架 來(lái)開(kāi)發(fā)HTML網(wǎng)頁(yè)游戲，雖不復(fù)雜，但有道是『紙上得來(lái)終覺(jué)淺，絕知此事要躬行』，代碼還是得親自多碼才行噢！
