这段代码有啥问题，就是没出来效果
const game = new Phaser.Game(375, 667, Phaser.AUTO);
const helloState = {
preload: function () {
game.stage.backgroundColor = "#a8d4bf";
game.load.image("logo", "/source/logo.png");
},
create: function () {
const text = game.add.text(game.world.centerX, 25, "hello world", {fill: '#fff'});
text.anchor.set(0.5);
const logo = game.add.image(game.world.centerX, game.world.centerY, "logo");
logo.anchor.set(0.5);
}
}
game.state.add("helloState", helloState);
game.state.start("helloState");
