left: 0
About Custom
You can use type="custom" to achieve a higher degree of freedom for the particle background.
let config = {
num: [4, 7],
rps: 0.1,
radius: [5, 40],
life: [1.5, 3],
v: [2, 3],
tha: [-40, 40],
// body: "./img/icon.png", // Whether to render pictures
// rotate: [0, 20],
alpha: [0.6, 0],
scale: [1, 0.1],
position: "center", // all or center or {x:1,y:1,width:100,height:100}
color: ["random", "#ff0000"],
cross: "dead", // cross or bround
random: 15, // or null,
g: 5, // gravity
// f: [2, -1], // force
onParticleUpdate: (ctx, particle) => {
ctx.beginPath();
ctx.rect(particle.p.x, particle.p.y, particle.radius * 2, particle.radius * 2);
ctx.fillStyle = particle.color;
ctx.fill();
ctx.closePath();
}
};
return (
<div>
<SignIn />
<ParticlesBg type="custom" config={config} bg={true} />
