ngx-tetris

Tetris game as an angular component

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

Check the demo here

Using it:

Install:

npm install ngx-tetris

Import

import {BrowserModule} from '@angular/platform-browser';
import {NgModule} from '@angular/core';

import {AppComponent} from './app.component';
import {TetrisCoreModule} from 'ngx-tetris';

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

Add/Connect to your fancy control interface

    <tetris-core #game
        (lineCleared)="onLineCleared()"></tetris-core>

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