Phaser 提供 3 個功能：預加載、創建、更新。如果create函數一開始就渲染一切，那怎么能在動態加載的時候強制畫圖呢？function preload(src = `images/Num_spin/Num_Spin_00359.png.webp`) {  this.load.image('background', 'images/table_en.png.webp');  this.load.image('wheel', 'images/UpperWheel.png.webp');  this.load.image('roulette', src);}function create() {  this.add.image(0, -160, 'background').setOrigin(0, 0).setScale(0.7);  this.add.image(20, 30, 'wheel').setOrigin(0, 0).setScale(0.7);  this.add.image(108, 110, 'roulette').setOrigin(0, 0).setScale(0.7)}function update() {  //Here I call a function that changes url}
