一、新建节点
1.在Start场景中新建Music节点，绑定canvas
2.在Game场景中新建Music节点
3.新建节点
4.新建Music脚本，绑定Canvas
Music.ts
const { ccclass, property } = cc._decorator;@ccclass
export default class NewClass extends cc.Component {@property({ type: cc.AudioSource, displayName: "背景音乐", tooltip: "背景音乐" })bg_music: cc.AudioSource = null;@property({ type: cc.AudioSource, displayName: "碰撞音效", tooltip: "碰撞音效" })collision: cc.AudioSource = null;@property({ type: cc.AudioSource, displayName: "buff音效", tooltip: "buff音效" })buff: cc.AudioSource = null;@property({ type: cc.AudioSource, displayName: "按钮音效", tooltip: "按钮音效" })btn: cc.AudioSource = null;//播放碰撞音效play_music_collision(){this.collision.play();}//播放buff音效play_music_buff(){this.buff.play();}//播放点击按钮音效play_music_btn(){this.btn.play();}
}
二、引用
1.Barrier.ts
//碰撞回调//当碰撞产生的时候调用other产生碰撞的另一个组件 self产生碰撞的自身的碰撞组件onCollisionEnter(other, self) {if (other.node.group == "bullet") {//获取GameController脚本let gc = cc.find("/Canvas").getComponent("GameController") as GameController;//获取Bullet脚本let c = other.getComponent("Bullet");//从脚本获取攻击力较少自身生命值this.reduce_num(c.ATK);// 如果可以加双倍分数if (gc.is_double == true) {//加分gc.add_score((c.ATK) * 2)}//如果不可以加双倍分数if (gc.is_double == false) {gc.add_score(c.ATK);}//销毁子弹other.node.destroy();}//发生了碰撞，无敌if (other.node.group == "invincible") {//获取GameController脚本let gc = cc.find("/Canvas").getComponent("GameController") as GameController;//如果可以加双倍分数if (gc.is_double == true) {//加双倍分gc.add_score(this.num * 2);}//如果不可以加双倍分else if (gc.is_double == false) {gc.add_score(this.num);}//自身销毁this.node.destroy()}//播放碰撞音效let music = cc.find("Canvas").getComponent("Music");music.play_music_collision();//如果自身生命值小于0if (this.num <= 0) {//自身销毁this.node.destroy();}}2.Buff.ts
//碰撞回调onCollisionEnter(other,self){//获取GameController脚本let gc = cc.find("Canvas").getComponent("GameController") as GameController;//如果子弹射速满了，就不增加射速了if(gc.bullet_speed<10000){//随机数0-10let n = this.randomNumber(0,10);//有一半几率执行子弹加速函数//也有一半几率执行子弹加攻击函数if(n>5){//加速buffgc.enhance_speed();}else{//加攻击buffgc.enhance_ATK();}}else{gc.enhance_ATK()}//自身销毁this.node.destroy()//播放音效let music = cc.find("Canvas").getComponent("Music");music.play_music_buff();}
三、菜单修改音乐音量
1.新建容器节点sound0
2.新建滑动器节点
Game_Menu.ts
@property({ type: music, displayName: "Music脚本所在节点", tooltip: "Music脚本所在节点" })music: music = null;@property({type: cc.Slider, displayName: "背景音乐音量滑动器", tooltip: "背景音乐音量滑动器"})sound_sd0: cc.Slider = null;//滑动背景音乐滑动器时调用的函数set_sound0() {//把滑动器的值赋给音乐this.music.bg_music.volume = this.sound_sd0.progress;}3.绑定canvas
四、菜单修改音效音量
1.新建容器节点sound1
2.新建滑动器节点
Game_Menu.ts
@property({ type: cc.Slider, displayName: "音效音量滑动器", tooltip: "音效音量滑动器" })sound_sd1: cc.Slider = null;//滑动音效滑动器时调用的函数set_sound1() {//把滑动器的值赋给音乐this.music.collision.volume = this.sound_sd1.progress;this.music.buff.volume = this.sound_sd1.progress;this.music.btn.volume = this.sound_sd1.progress;}
