Cocos creator实现飞机大战空中大战《战击长空》小游戏资源及代码
最近在学习Cocos Creator，作为新手，刚刚开始学习Cocos Creator，刚刚入门，这里记录一下飞机大战小游戏实现。

在这里插入图片描述

一安装CocosDashBoard

这里就不介绍如何安装了

二新建2D项目FlyWar

2.1、管理项目目录
在资源管理器中新建文件夹

anim 动画
preb 预制体
res 图片、语音资源
scene 场景
scripts 脚本资源
将资源文件拖到res目录下

在这里插入图片描述

三、关键步骤

3.1 实现背景的移动代码

背景的星空会有移动的效果

import GameConstant from "./GameConstant";const {ccclass, property} = cc._decorator;@ccclass
export default class MoveBackground extends cc.Component {    bgs : cc.Node[];@propertyspeed : number = 50;canvasWidth: number;canvasHeight: number;onLoad () {let canvas = cc.find('Canvas');this.canvasWidth = canvas.width;this.canvasHeight = canvas.height;// 注册特定事件cc.director.on(GameConstant.kUpdateGameStatus, this.listenGameStatus, this);}listenGameStatus() {}start () {this.node.width= this.canvasWidth;this.node.height = this.canvasHeight;this.bgs = this.node.children;for (let index = 0; index < this.bgs.length; index++) {let element = this.bgs[index];element.width = this.canvasWidth;element.height = this.canvasHeight;}// 设置默认if (this.bgs.length >= 2) {this.bgs[1].y = this.bgs[0].y + this.bgs[0].height; }}update (dt) {this.bgs[0].y -= this.speed * dt;this.bgs[1].y -= this.speed * dt;if (this.bgs[0].y < -this.canvasHeight) {this.bgs[0].y = this.bgs[1].y + this.bgs[1].height;}if (this.bgs[1].y < -this.canvasHeight) {this.bgs[1].y = this.bgs[0].y + this.bgs[0].height;}}
}

3.2 实现自己飞机的绑定击碰撞检测

在这里插入图片描述

首先将load方法中开启碰撞检测

// 碰撞检测
cc.director.getCollisionManager().enabled = true;

将手指移动飞机

start() {// touch inputthis.node.on(cc.Node.EventType.TOUCH_START, this.onTouchBegan, this);this.node.on(cc.Node.EventType.TOUCH_END, this.onTouchEnded, this);this.node.on(cc.Node.EventType.TOUCH_CANCEL, this.onTouchEnded, this);this.node.on(cc.Node.EventType.TOUCH_MOVE, this.onTouchMove, this);}// touch事件onTouchBegan(event) {if (this.isSelected == true) {return;}let position = event.getLocation();this.isSelected = true;this.touchStartX = position.x;this.touchStartY = position.y;}onTouchEnded() {this.isSelected = false;}onTouchMove(e: cc.Event.EventTouch) {let gameStatus = GameStateManager.instance().getGameStatus();if (this.isSelected && (GameConstant.GameStatus.BOSSBOOMFINISH != gameStatus)) {let position = e.getLocation();let moveX = position.x;let moveY = position.y;let disX = (moveX - this.touchStartX);let disY = (moveY - this.touchStartY);this.updateNodeX(disX, disY);this.touchStartX = position.x;this.touchStartY = position.y;}}// 更新位置updateNodeX(distanceX, distanceY) {this.playerRoot.x += distanceX;if (this.playerRoot.x < -this.canvasWidth / 2) {this.playerRoot.x = -this.canvasWidth / 2;}if (this.playerRoot.x > this.canvasWidth / 2) {this.playerRoot.x = this.canvasWidth / 2;}this.playerRoot.y += distanceY;if (this.playerRoot.y < -this.canvasHeight / 2) {this.playerRoot.y = -this.canvasHeight / 2;}if (this.playerRoot.y > this.canvasHeight / 2) {this.playerRoot.y = this.canvasHeight / 2;}this.playerBulletRoot.x = this.playerRoot.x;this.playerBulletRoot.y = this.playerRoot.y + 50;}

玩家飞机的碰撞，当碰撞到不同的敌机就会出现血量减少的

onCollisionEnter(other, self) {if (this.isDead == true) {return;}let deltax = 0;if (other.tag == 999) {// 撞击到敌机BOSS// dead，游戏结束，跳转到结果页面this.isDead = true;this.showPlaneBoom();return;}if (other.tag == 888) {// 获得金币，每个金币50分this.updateScore();}if (other.tag == 911) {// 获得血量this.updateBlood();}if (other.tag == 100 || other.tag == 914) {// 默认子弹 -1// 减去血量this.bloodNumber -= 1;deltax = 1;} else if (other.tag == 101 || other.tag == 102) {// boss大炮弹 -5this.bloodNumber -= 5;deltax = 5;} else if ((other.tag == 90 || other.tag == 91)) {// 敌机 -2this.bloodNumber -= 2;deltax = 2;}if (this.bloodNumber <= 0) {// dead，游戏结束，跳转到结果页面this.isDead = true;this.showPlaneBoom();}if (this.bloodNumber < 0) {this.bloodNumber = 0;}this.updateBloodUI(deltax);}

3.2 实现当前飞机发射子弹的效果

在这里插入图片描述

当前子弹发射会有角度设置，代码如下

import EnemyPlane from "./EnemyPlane";const {ccclass, property} = cc._decorator;// 直线的Bullet类型
@ccclass
export default class BulletLiner extends cc.Component {// 角度，默认90@property(Number)rotation: number = 90;// 速度@property(Number)speed: number = 1000;// 时间@property(Number)time: number = 0.0;// 时间点lifeTime: number = 2.5;// LIFE-CYCLE CALLBACKS:// 初始位置originPos: any;canvasWidth: number;canvasHeight: number;isDead: boolean = false;onLoad() {let canvas = cc.find('Canvas');this.canvasWidth = canvas.width;this.canvasHeight = canvas.height;}start () {this.originPos = this.node.position;}update (dt) {this.onMove(dt);}// 移动onMove(dt) {let distance = dt * this.speed;let radian = this.rotation * Math.PI / 180;let v2 = this.node.position; let delta = cc.v2(distance * Math.cos(radian), distance * Math.sin(radian));v2.x += delta.x;v2.y += delta.y;this.node.position = v2;if (v2.y > this.canvasHeight) {this.node.removeFromParent();this.node.destroy();}}onCollisionEnter(other, self) {if ((other.tag != 110 && other.tag != 1111 && other.tag != 9911 && other.tag != 911 && other.tag != 888) && !this.isDead) {this.die();}}die() {this.isDead = true;this.node.removeFromParent();this.destroy();}
}

3.4 敌机的移动击及碰撞检测

import GameStateManager from "./GameStateManager";const { ccclass, property } = cc._decorator;// 敌人飞机
@ccclass
export default class EnemyPlane extends cc.Component {// 角度，默认90@property(Number)rotation: number = 90;// 速度@property(Number)speed: number = 1000;// 时间@property(Number)time: number = 0.0;// 时间点lifeTime: number = 2.5;// LIFE-CYCLE CALLBACKS:// 初始位置originPos: any;canvasWidth: number;canvasHeight: number;@property(cc.Prefab)enemyBoom: cc.Prefab = null;@property(cc.Prefab)enemyBullet: cc.Prefab = null;@property([cc.Prefab])coinPrebs: cc.Prefab[] = [];// 音效资源@property(cc.AudioClip)boomAudio: cc.AudioClip = null;isDead: boolean = false;isBoomAnimating: boolean = false;onLoad() {let canvas = cc.find('Canvas');this.canvasWidth = canvas.width;this.canvasHeight = canvas.height;}start() {this.originPos = this.node.position;this.enemyBulletSchedule();}update(dt) {this.onMove(dt);}// 移动onMove(dt) {// this.time += dt;// if (this.time >= this.lifeTime) {//     this.node.position = this.originPos;//     this.time = 0;// }let distance = dt * this.speed;let radian = this.rotation * Math.PI / 180;let v2 = this.node.position;let delta = cc.v2(distance * Math.cos(radian), distance * Math.sin(radian));v2.x -= delta.x;v2.y -= delta.y;this.node.position = v2;if (v2.y < -this.canvasHeight) {this.node.removeFromParent();this.node.destroy();}}// 动效效果showPlaneBoom() {if (this.isBoomAnimating) {return;}// 调用声音引擎播放声音cc.audioEngine.playEffect(this.boomAudio, false);this.isBoomAnimating = true;// 播放动画let boom;let callFunc = cc.callFunc(function () {this.createCoin();boom = cc.instantiate(this.enemyBoom);this.node.parent.addChild(boom);boom.setPosition(this.node.position);this.node.removeFromParent();let anim = boom.getComponent(cc.Animation);anim.play('enemy_boom');}, this);let aTime = cc.delayTime(0.1);let finish = cc.callFunc(function () {boom.removeFromParent();boom.destroy();this.isBoomAnimating = false;this.removeFromParent();this.destroy();}, this);// 创建一个缓动var tween = cc.tween()// 按顺序执行动作.sequence(callFunc, aTime, finish);cc.tween(this.node).then(tween).start();}onCollisionEnter(other, self) {if ((other.tag == 110 || other.tag == 1111) && !this.isDead) {this.die();}}die() {this.isDead = true;this.showPlaneBoom();this.updateScore();}// 更新得分updateScore() {// 每个敌机得分为10GameStateManager.instance().updateScore(10);}// 创建金币 每个金币10分createCoin() {let delta = 50;for (let index = 0; index < this.coinPrebs.length; index++) {let coin = cc.instantiate(this.coinPrebs[index]);this.node.parent.addChild(coin);coin.setPosition(this.node.position);coin.x = this.node.x + Math.random() * delta;coin.y = this.node.y;}}// 倒计时enemyBulletSchedule() {this.schedule(this.onCreateEnemyBullet, 1.5);}onCreateEnemyBullet() {let bullet = cc.instantiate(this.enemyBullet);this.node.parent.addChild(bullet);bullet.setPosition(this.node.position);bullet.x = this.node.x;bullet.y = this.node.y;}stopSchedule() {this.unschedule(this.onCreateEnemyBullet);}protected onDestroy(): void {this.stopSchedule();}
}

3.5 敌机BOSS

敌机BOSS有血量

当前敌机BOSS只要血量为0时候就是击败了该BOSS

}

3.6 敌机BOSS来回移动并且发射导弹

// 左右移动moveLeftRight() {// 让节点左右来回移动并一直重复var seq = cc.repeatForever(cc.sequence(cc.moveTo(5, cc.v2(-this.canvasWidth / 2, this.node.y)),cc.moveTo(5, cc.v2(this.canvasWidth / 2, this.node.y))));this.node.runAction(seq);}
