我正在尝试重新启动Phaser 3中的游戏场景，并且在调用this.scene.restart时，在phaser.js脚本的setVelocityX中出现一条错误消息，指出“ this.body is undefined”（未缩小的行169442）脚本（如果有帮助）
我正在使用最新版本的Phaser v3.19.0。 当玩家精灵与敌人碰撞时会调用hitEnemy函数，这会暂停物理过程并将gameOver设置为true。在update（）函数中，我正在检查gameOver是否为true，以及是否按下了“ R”键，在这种情况下，将调用scene.restart（） 以下是我的代码的一部分：

我主要在本教程示例的项目中使用过它，在此示例中它工作得很好，并且我在此处使用相同的代码。一般来说，我对Phaser和游戏开发非常陌生，因此对您的帮助将不胜感激。 谢谢
答案 0 :(得分：0)
您可以这样做：
create(){
duce.isReady = false
// Your code here...
dude.isReady = true
}
update(){
if(dude.isReady){
dude.body.setVelocityX(...)
// Rest of your code concerning dude
}
}
