Simple-tetris NPM

Simple Tetris

This package provides API that allows you to easily create clones of the Tetris game. It handles game core - your role is to write the UI. Library was inspired by Redux and was written from scratch in TypeScript.

NOTE: This project is still not finished. More details in the TODO section below.

Play online - use WSAD keys on Desktop or on-screen buttons on Mobile devices.

Simplest code example:

  <button onClick="handleEvent(SimpleTetris.KEY_CODE_LEFT);">left</button>
  <button onClick="handleEvent(SimpleTetris.KEY_CODE_RIGHT);">right</button>
  <button onClick="handleEvent(SimpleTetris.KEY_CODE_HARD_DROP);">down</button>
  <button onClick="handleEvent(SimpleTetris.KEY_CODE_ROTATE);">rotate</button>

  <script>
    var store;

    function handleEvent(keyCode) {
      SimpleTetris.gameLoopIteration(store, 0.0, keyCode);
      render();
    }

    function render() {
      var matrixBlocksToRender = SimpleTetris.matrixBlocksToRenderSelector(store.getState());
      var html = '';

      for (var i = 0; i < matrixBlocksToRender.length; i++) {
        html += matrixBlocksToRender[i] ? '<div class="filled"></div>' : '<div></div>';
      }
      document.getElementById('game-root').innerHTML = html;
    }

    function run() {
      store = new SimpleTetris.createStore();
      render();
    }

Installation

npm install simple-tetris

Ascii Runner alternative

If you just want to play the game and don't want to use any API you can simply use build-in Ascii Runner.

Play online - use Arrows on Desktop or on-screen buttons on Mobile devices.

<pre id="root"></pre>
<script src="https://unpkg.com/simple-tetris"></script>
<script>
  var asciiRunner = new SimpleTetris.AsciiRunner();
</script>

It works in terminal as well:

npm install simple-tetris && node node_modules/simple-tetris/dist/ascii-runner-node.js

Content of the ascii-runner-node.js is as simple as:

const SimpleTetris = require('simple-tetris');
const asciiRunner = new SimpleTetris.AsciiRunner();

ASCII runner uses my other library (terminal-game-io) that simplifies basic input and output of the text based games.

Changelog

Still TODO

move tetrimino one line down after given interval (probably in 1.4.x)
when tetrimino will hit the 'ground' trigger new tetrimino (probably in 1.5.x)
detect and remove completely filled lines (probably in 1.6.x)
detect game over / pause game (probably in 1.7.x)
...
(?) remove terminal-game-io from typescript definitions of src/lib/ascii-runner.ts file and move this lib back to devDeps (breaking change, probably in 2.0.0)
updates in interfaces like TetriminoRotation, TetriminoType instead of index, etc (breaking change, probably in 2.0.0)
add separate Enum for Keys and remove KEYCODE* constants (breaking change, probably in 2.0.0)
soft drop (probably in 2.x.x)
remove completely filled line 'blink' effect (probably in 2.x.x)
block colors (probably in 2.x.x)
score (probably in 2.x.x)
next piece preview (probably in 2.x.x)
...

1.3.0 - ?? ?? 2018

todo implement hard drop and integrate it with collision detection (probably in 1.3.x)

1.2.0 - 25 November 2018

collision detection both with borders and other blocks
updates in internal 'Simple Redux' implementation
small performance fix in matrixBlocksToRenderSelector
tetriminos now rotates clockwise

bugfix related to terminal-game-io dependency issue

1.1.1 - 18 November 2018

adds dedicated 'GameLoopIteration' type that solves the problem in the *.d.ts file used by older typescript compilers

npm keywords update
big update in examples (external stackblitz examples, internal API client example)
big update in readme (code examples, animated gifs)
simple-tetris is finally easy to import in any other project

1.1.0 - 13 September 2018

rename 'assets' directory to 'templates'

1.0.0 - 06 August 2018

initial version of the project, nothing more than the PoC

Want to check this project in development mode?

Development mode is using Ascii Runner supported by terminal-game-io library.

git clone https://github.com/robertrypula/simple-tetris.git
cd simple-tetris
npm install

npm run dev-browser

You can develop and play Tetris directly in the terminal. It works even via the SSH connections.

npm run dev-node
