鸿蒙Arkts开发飞机大战小游戏，包含无敌模式，自动射弹，暂停和继续

飞机大战可以把飞机改成图片，目前包含无敌模式，自动射弹，暂停和继续的功能

代码如下：

// 定义位置类
class GamePosition {x: numbery: numberconstructor(x: number, y: number) {this.x = xthis.y = y}
}@Entry
@Component
struct PlaneGame {@State isPaused: boolean = false // 添加暂停状态@State playerX: number = 180@State playerY: number = 400  // 降低初始Y位置@State bullets: GamePosition[] = []@State enemies: GamePosition[] = []@State score: number = 0@State isGameOver: boolean = false@State isInvincible: boolean = false  // 添加无敌状态@State autoFire: boolean = false  // 添加自动发射状态// 修改移动速度从8提高到15private speed: number = 15      // 大幅提高移动速度private bulletSpeed: number = 15private enemySpeed: number = 3private enemySpawnRate: number = 45private fireInterval: number = 10  // 自动发射间隔(帧数)private frameCount: number = 0private planeSize: number = 40  // 减小尺寸private bulletSize: number = 8private enemySize: number = 40private isLeftPressed: boolean = falseprivate isRightPressed: boolean = falseprivate isFirePressed: boolean = falseprivate gameInterval: number = 0 // 添加游戏循环引用// 添加togglePause方法togglePause() {this.isPaused = !this.isPaused// 强制状态更新this.score = this.score + 0console.log(`游戏已${this.isPaused ?
