休闲游戏案例:抓蝴蝶
创建Cocos游戏项目
// Butterfly.ts - 蝴蝶行为逻辑
const { ccclass, property } = _decorator;
@ccclass(‘Butterfly’)
export class Butterfly extends Component {
@property(SpriteFrame)
patterns: SpriteFrame[] = []; // 蝴蝶纹理数组
private speed: number = 0;
private patternIndex: number = 0;
start() {
this.changePattern();
this.schedule(this.flyRandom, 2);
flyRandom() {
this.speed = Math.random() * 300 + 100;
const angle = Math.random() Math.PI 2;
const vx = Math.cos(angle) * this.speed;
const vy = Math.sin(angle) * this.speed;
tween(this.node)
.by(1, { position: new Vec3(vx, vy, 0) })
.start();
changePattern() {
this.patternIndex = (this.patternIndex + 1) % this.patterns.length;
this.getComponent(Sprite).spriteFrame = this.patterns[this.patternIndex];
this.scheduleOnce(this.changePattern, 0.5);
onClick() {
this.unscheduleAllCallbacks();
tween(this.node)
.to(0.3, { scale: new Vec3(0, 0, 0) })
.call(() => this.node.destroy())
.start();
gameManager.onButterflyCaptured();
}
游戏管理器实现
// GameManager.ts
@ccclass(‘GameManager’)
export class GameManager extends Component {
@property(Prefab)
butterflyPrefab: Prefab = null!;
@property(Label)
scoreLabel: Label = null!;
@property([Node])
spawnPoints: Node[] = [];
private score: number = 0;
private butterflies: Node[] = [];
start() {
this.schedule(this.spawnButterfly, 1.5);
spawnButterfly() {
if (this.butterflies.length >= 8) return;
const point = this.spawnPoints[Math.floor(Math.random() * this.spawnPoints.length)];
const butterfly = instantiate(this.butterflyPrefab);
butterfly.setPosition(point.position);
butterfly.parent = this.node.parent;
butterfly.on(Node.EventType.TOUCH_END, () => {
butterfly.getComponent(Butterfly).onClick();
});
this.butterflies.push(butterfly);
onButterflyCaptured() {
this.score++;
this.scoreLabel.string = 得分: ${this.score};
this.butterflies.pop();
if (this.score % 5 === 0) {
this.distributeToOtherDevices();
}
distributeToOtherDevices() {
// 调用HarmonyOS分布式能力
harmonyOSService.distributeGameState({
event: 'levelUp',
level: Math.floor(this.score / 5) + 1
});
}
HarmonyOS 5.0 适配实践
创建HarmonyOS工程配置

分布式能力接入
// HarmonyOSService.ets
import distributedData from ‘@ohos/distributedData’;
import deviceInfo from ‘@ohos/deviceInfo’;
export class HarmonyOSService {
private kvManager: distributedData.KVManager;
private kvStore: distributedData.KVStore;

Cocos与HarmonyOS融合实践
跨引擎桥接层
// HarmonyOSAdapter.ts
declare namespace harmonyos {
function enableBackGesture(enabled: boolean): void;
function getDeviceType(): string;
function shareScore(score: number): Promise<boolean>;
@ccclass(‘HarmonyOSAdapter’)
export class HarmonyOSAdapter extends Component {
public static isHarmonyOS: boolean = false;
start() {
this.detectHarmonyOS();
this.adaptUIForDevice();
private detectHarmonyOS() {
try {
// @ts-ignore
HarmonyOSAdapter.isHarmonyOS = !!globalThis.requireNapi;
catch (e) {
HarmonyOSAdapter.isHarmonyOS = false;
}
private adaptUIForDevice() {
if (!HarmonyOSAdapter.isHarmonyOS) return;
const deviceType = harmonyos.getDeviceType();
switch (deviceType) {
case 'phone':
this.adaptForPhone();
break;
case 'tablet':
this.adaptForTablet();
break;
case 'tv':
this.adaptForTV();
break;
}
private adaptForPhone() {
harmonyos.enableBackGesture(false);
find(‘Canvas/UI’).scale = 0.9;
private adaptForTablet() {
harmonyos.enableBackGesture(true);
find('Canvas/UI').scale = 1.2;
this.setControlAreas();
private setControlAreas() {
// 大屏设备拆分控制区域
const areaLeft = new Rect(-200, -300, 400, 600);
const areaRight = new Rect(200, -300, 400, 600);
input.setMultiTouchEnabled(true);
input.setTouchRect(0, areaLeft); // 左手控制区
input.setTouchRect(1, areaRight); // 右手控制区
}
ArkUI游戏UI界面
// GameUI.ets
import { HarmonyOSService } from ‘./HarmonyOSService’;
@Entry
@Component
struct GameUI {
@State gameScore: number = 0;
private harmonyService = new HarmonyOSService();
build() {
Column() {
// Cocos渲染视图
CocosCanvas({
id: ‘cocosCanvas’,
width: ‘100%’,
height: ‘85%’
})
// HarmonyOS原生UI控制区
Row() {
Button('分享分数')
.onClick(() => this.shareScore())
.width('40%')
Button('设备协作')
.onClick(() => this.startDeviceCollaboration())
.width('40%')
.width(‘100%’)
.height('15%')
.justifyContent(FlexAlign.SpaceAround)
}
shareScore() {
harmonyService.distributeGameState({
event: ‘shareScore’,
score: this.gameScore
});
startDeviceCollaboration() {
harmonyService.startMultiDeviceMode().then(() => {
cocosEngine.sendMessage('GameManager', 'enableCollaboration');
});
displaySharedScore(score: number) {
AlertDialog.show({
title: '协作玩家得分',
message: 其他设备玩家得分: ${score},
confirm: () => {}
});
onCocosEvent(event: string, data: any) {
if (event === 'scoreUpdate') {
this.gameScore = data.score;
}
性能优化策略
跨引擎渲染优化
// RenderOptimizer.ts
export function adjustRenderPipeline(deviceType: string) {
const pipeline = director.root.pipeline;
// 中低端设备优化策略
if (deviceType = ‘phone’ || deviceType = ‘wearable’) {
pipeline.addBloomPass({ enable: false });
pipeline.addSkinningPass({ maxBoneCount: 32 });
pipeline.addShadowPass({ type: ShadowType.PLANAR });
pipeline.addUIPass({ useInstancing: false });
// 动态调整纹理质量
const maxSize = deviceType === 'wearable' ? 1024 : 2048;
AssetManager.textureLoader.maxSize = maxSize;
// 内存优化设置
dynamicAtlasManager.enabled = true;
dynamicAtlasManager.maxAtlasCount = 3;
// 高端设备增强效果
if (deviceType = ‘tablet’ || deviceType = ‘tv’) {
pipeline.addAntiAliasingPass({ samples: 4 });
pipeline.addGlobalIlluminationPass({ enable: true });
}
分布式协同数据同步策略
// MultiDeviceSync.ts
export class MultiDeviceSync {
private static updateQueue: SyncData[] = [];
private static lastSyncTime: number = 0;
public static queueUpdate(dataType: string, data: any) {
this.updateQueue.push({ dataType, payload: data });
this.processQueue();
private static processQueue() {
const now = Date.now();
if (now - this.lastSyncTime < 100) return;
// 合并类型相同的数据包
const combined: Record<string, any> = {};
for (const item of this.updateQueue) {
if (!combined[item.dataType]) combined[item.dataType] = [];
combined[item.dataType].push(item.payload);
// 发送合并数据
harmonyOSService.distributeGameState({
event: 'multiUpdate',
timestamp: now,
data: combined
});
this.updateQueue = [];
this.lastSyncTime = now;
}

避坑指南:常见问题与解决方案
纹理加载失败问题
// 兼容不同设备格式要求
AssetManager.assetOptions = {
platform: getHarmonyOSPlatform(),
isWebpSupported: true,
isAstcSupported: (device.gpu.indexOf(‘Mali-G78’) > -1),
isPvrtcSupported: (device.vendor === ‘Apple’)
};
分布式数据同步异常
// 数据序列化兼容方案
function safeStringify(data: any) {
const cache = new Set();
return JSON.stringify(data, (key, value) => {
if (typeof value = ‘object’ && value ! null) {
if (cache.has(value)) return;
cache.add(value);
return value;
});
多设备输入冲突
// 输入源识别逻辑
input.on(Input.EventType.TOUCH_START, (touch: Touch) => {
const deviceId = harmonyOS.getEventDeviceId(touch);
if (deviceId !== this.localDeviceId) {
// 忽略其他设备输入
touch.claim();
});
