# Particles

You can show particles in your game, useful for representing rain, snow, fire, explosions etc!

You must first declare your particles:

```javascript
var particles = {
    "Snow": {
        "particles": {
            "number": {
                "value": 400,
                "density": {
                    "enable": true,
                    "value_area": 800
                }
            },
            "color": {
                "value": "#fff"
            },
            "shape": {
                "type": "circle",
                "stroke": {
                    "width": 0,
                    "color": "#000000"
                },
                "polygon": {
                    "nb_sides": 5
                },
                "image": {
                    "src": "img\/github.svg",
                    "width": 100,
                    "height": 100
                }
            },
            "opacity": {
                "value": 0.5,
                "random": true,
                "anim": {
                    "enable": false,
                    "speed": 1,
                    "opacity_min": 0.1,
                    "sync": false
                }
            },
            "size": {
                "value": 10,
                "random": true,
                "anim": {
                    "enable": false,
                    "speed": 40,
                    "size_min": 0.1,
                    "sync": false
                }
            },
            "line_linked": {
                "enable": false,
                "distance": 500,
                "color": "#ffffff",
                "opacity": 0.4,
                "width": 2
            },
            "move": {
                "enable": true,
                "speed": 6,
                "direction": "bottom",
                "random": false,
                "straight": false,
                "out_mode": "out",
                "bounce": false,
                "attract": {
                    "enable": false,
                    "rotateX": 600,
                    "rotateY": 1200
                }
            }
        },
        "interactivity": {
            "detect_on": "canvas",
            "events": {
                "onhover": {
                "enable": true,
                "mode": "bubble"
            },
            "onclick": {
                "enable": true,
                "mode": "repulse"
            },
            "resize": true
        },
        "modes": {
            "grab": {
                "distance": 400,
                "line_linked": {
                    "opacity": 0.5
                }
            },
            "bubble": {
                "distance": 400,
                "size": 4,
                "duration": 0.3,
                "opacity": 1,
                "speed": 3
            },
            "repulse": {
                "distance": 200,
                "duration": 0.4
            },
            "push": {
                "particles_nb": 4
            },
            "remove": {
                "particles_nb": 2
            }
        }
    },
        "retina_detect": true
    }
}
```

Then, whenever you want to show them, just use the particles command:

```javascript
"particles Snow"
```

And to stop them:

```javascript
"stop particles"
```

If you want more examples, you can find them in the [GitHub page of the library](https://github.com/VincentGarreau/particles.js/)

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://developers.monogatari.io/documentation/1.3.0/script/particles.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
