游戏核心代码与功能实现
核心代码实现
``javascript
// 初始化基础配置
const config = {
type: Phaser.AUTO,
width: 360,
height: 600,
physics: {
default: 'arcade',
arcade: { gravity: { y: 800 } }
},
scene: {
preload: preload,
create: create,
update: update
};
let bottle, platforms, cursors, score = 0;
const game = new Phaser.Game(config);
function preload {
this.load.image('bottle', 'assets/bottle.png');
this.load.image('platform', 'assets/platform.png');
function create {
// 初始化游戏对象
bottle = this.physics.add.sprite(180, 500, 'bottle');
platforms = this.physics.add.staticGroup;
// 生成初始平台
createPlatform(180, 580);
generateRandomPlatform;
// 设置碰撞检测
this.physics.add.collider(bottle, platforms, (obj, platform) => {
if (obj.y< platform.y) {
score++;
generateRandomPlatform;
destroyBottomPlatform;
});
// 平台生成逻辑
function generateRandomPlatform {
const xPos = Phaser.Math.Between(50, 310);
const yPos = platforms.children.entries.y
createPlatform(xPos, yPos);
`
关键功能实现
1.跳跃控制机制:
`javascript
function update {
if (cursors?.space.isDown && bottle.body.touching.down) {
bottle.setVelocityY(-500);
`
2.动态难度系统:
`javascript
// 在create中添加
this.time.addEvent({
delay: 10000,
callback: => {
this.physics.world.gravity.y += 50;
},
loop: true
});
`
资源优化方案
`javascript
this.textures.setTextureFilter('bottle', Phaser.Textures.FilterMode.NEAREST);

快速适配指南
1. 修改重力参数:调整config中的gravity.y值
2. 自定义跳跃高度:修改setVelocityY的负值参数
3. 平台间距调整:修改generateRandomPlatform中的yPos计算值
