title: How do you blur a single object in Matter.js?
body: <p>I'm trying to create a fire effect for a game in Matter.js, and I need to blur a circle to make it look more realistic. However, I need to make it so it only blurs the fire, not the whole canvas. How can I do this?</p>
  
  <p>This is the code I have so far:</p>
  
  <pre><code>function setOnFire(object) {
      var fireX = object.position.x;
      var fireY = object.position.y;
      var fire = Bodies.circle(fireX, fireY, vw*1, {
          isStatic: true,
          render: {
              fillStyle: "rgba(255,130,0,1)"
          }
      });
      World.add(world, fire);
  }
  </code></pre>
