我想在Angular项目中使用p5.js时遇到问题。
我使用Angular CLI。 在我的 .angular-cli.json 文件中包含p5.js:
"scripts": [
"../node_modules/p5/lib/p5.min.js",
"../node_modules/p5/lib/addons/p5.sound.js",
"../node_modules/p5/lib/addons/p5.dom.js"
],
然后在我的组件中写道:
import { Component, OnInit } from '@angular/core';
import * as p5 from 'p5';
@Component({
selector: 'app-player',
templateUrl: './player.component.html',
styleUrls: ['./player.component.scss']
})
export class PlayerComponent implements OnInit {
play: boolean = false;
constructor() { }
ngOnInit() {
const s = (p) => {
let song;
let canvas;
p.preload = () => {
console.log('preload');
song = p.loadSound('assets/music/Thunderstruck.mp3');
}
p.setup = () => {
canvas = p.createCanvas(595, 100);
canvas.parent('equalizer');
p.background(0);
}
}
let player = new p5(s);
}
onPlay() {
this.play = !this.play;
}
}
然后当我想加载我的歌并使用 loadSound()时,JS告诉我 错误TypeError:p.loadSound不是函数
好的,JS在我的文件中找不到这个方法,但是在浏览器控制台中我可以这样写:
let song = p5.prototype.loadSound('assets/music/Thunderstruck.mp3');
song.play();
一切正常(screenshot of my console)!
我试着在我的组件中写道:
song = p.prototype.loadSound('assets/music/Thunderstruck.mp3');
它不起作用。
我做错了什么?
答案 0 :(得分:2)
替换
import * as p5 from 'p5';
*
declare var p5: any;
答案 1 :(得分:-1)
我不知道为什么,但对我来说,在调用 p5sound
之前记录 loadSound
使它起作用。
与:
import * as p5 from 'p5';
import * as p5sound from 'p5/lib/addons/p5.sound';
和:
console.log(p5sound)
this.song = s.loadSound('assets/samples/CpW_WetHitE-01.wav');
