安装

npm i confetti-ts-canvas

引入

import {
    ConfettiEjector,
    CanvasRender,
    CustomShape
} from 'confetti-ts-canvas';

初始化

const g=uni.createCanvasContext("myCanvas");
const canvasRender=new CanvasRender();
canvasRender.init(
        //必填 CanvasContext
        g,
        //可选填入
        {
            width:canvas.width,
            height:canvas.height,
        },
        //以下参数全部可选填入
        {
            onFinished(){
                console.log("完成")
            },
            displayFps:true,
            grivaty:.5,
        }
    );

使用

const pao = new ConfettiEjector(canvasRender, {
    limitAngle: [225, 315],//喷发角度区间[-∞,+∞]
    count: 100,//喷发纸片数量
});
const boom = pao.create({
    x: Math.random()*(this.canvasSize.width*.5),
    y:Math.random()*(this.canvasSize.height*.5),//喷发位置
    clampforce: [20, 60],//喷发力度
    radius: 10,//纸片大小
});
pao.fire(boom);
