# ngx-snake

Snake game as an angular component

***ngx-snake*** is actually only the ***core of the game***... YOU need to add everything around it (controls, score...)  yourself :)


Check the demo [here](http://chrum.it/pages/ngx-snake)

## Using it:
#### Install:

```bash
npm install ngx-snake
```

#### Import
```javascript
import {BrowserModule} from '@angular/platform-browser';
import {NgModule} from '@angular/core';

import {AppComponent} from './app.component';
import {NgxSnakeModule} from 'ngx-snake';

@NgModule({
    declarations: [
        AppComponent,
    ],
    imports: [
        BrowserModule,
        NgxSnakeModule
    ],
    providers: [],
    bootstrap: [AppComponent]
})
export class AppModule {
}
```

#### Add/Connect to your fancy control interface
```html
    <ngx-snake #game></ngx-snake>

<button (click)="game.actionStart()">Start</button>
<button (click)="game.actionStop()">Stop</button>
<button (click)="game.actionReset()">Reset</button>

### Styling

To change colors and tiles (to **black and white** for example) define styles with colors like
```scss
ngx-snake {
    ngx-snake-tile {
        background: #ffffff;
        &.free {
            div {
                background: #ffffff;
            }
        }
    }
}
```
for full example (and all class names) [go here](https://github.com/chrum/ngx-snake/blob/master/projects/ngx-snake-app/src/styles.scss)

## Development


Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.
