| 1. 按住屏幕，棍子伸长，放开手指，棍子放下。 |
| 2. 具备计时性能。 |
| 3. 计时完结或者棍子没有放到平安区域，则游戏完结。 |
独自一个 Scene 作为背景，避免显示 Scene 重叠时有遮挡
// background.tsexport default class extends Phaser.Scene { constructor() { super({ key: 'BackgroundScene', active: true }); } create(): void { const graphics = this.add.graphics(); graphics.fillGradientStyle(0x241a47, 0x241a47, 0x274aa0, 0x274aa0); graphics.fillRect(0, 0, window.game.width, window.game.height); this.scene.launch('FootScene'); this.scene.launch('StartScene'); }}底部组件
底部的云层成果作为公共组件应用
// foot.tsimport pngCloud from '@images/cloud.png';const config: FootConfig = { circleNum: 7, blueCircleFrame: 0, whileCircleFrame: 1, blueCloudY: 160, whileCloudY: 190, height: 90};export default class extends Phaser.Scene { constructor() { super({ key: 'FootScene' }); } preload(): void { this.load.spritesheet('ssCloud', pngCloud, { frameWidth: 256, frameHeight: 256}); } create(): void { const blueGroup = this.add.group([], { key: 'ssCloud', frame: [config.blueCircleFrame], frameQuantity: config.circleNum, setXY: { y: config.blueCloudY, stepX: 120, stepY: 0 } }); const whileGroup = this.add.group([], { key: 'ssCloud', frame: [config.whileCircleFrame], frameQuantity: config.circleNum, setXY: { y: config.whileCloudY, stepX: 120, stepY: 0 } }); this.resize(); window.addEventListener('resize', () => { this.resize(); }); } resize(): void { const viewHeight = document.documentElement.clientHeight / window.rem; const camerasY = (window.game.height - viewHeight) / 2 + viewHeight - config.height; this.cameras.main.setPosition(0, camerasY); }}增加动画
// foot.tsexport default class extends Phaser.Scene { create(): void { this.add.tween({ targets: blueGroup.getChildren(), props: { y: (target) => { return target.y + Phaser.Math.Between(-5, 0); }, scale: (target) => { return target.scale + Phaser.Math.FloatBetween(-0.05, 0.05); } }, duration: 3000, yoyo: true, repeat: -1, ease: Phaser.Math.Easing.Sine.InOut }); this.add.tween({ targets: whileGroup.getChildren(), props: { y: (target) => { return target.y + Phaser.Math.Between(-5, 0); }, scale: (target) => { return target.scale + Phaser.Math.FloatBetween(0, 0.1); } }, duration: 3000, yoyo: true, repeat: -1, ease: Phaser.Math.Easing.Sine.InOut }); }}适配，始终显示在窗口底部，css 的 fixed 成果

- phaser 自身的适配仿佛没有绝对窗口定位的性能（相似 css 的 fixed），如果游戏中有这样的需要的话，就得本人手动再做多一步适配。
- phaser 和 webpack 联合导入资源时，感觉有些麻烦，须要先
import之后再应用 phaser 的loader，不能一步到位。
以上若有好的解决办法，还请各位不吝赐教。
