# V 2048
|
|
|
|
This is a simple 2048 game, written in [the V programming language](https://vlang.io/).

|
|
WebAssembly demo: https://v2048.vercel.app
|

|
|
|
|
## Description
|
|
|
|
Merge tiles by moving them.
|
|
After each move, a new random tile is added (2 or 4).
|
|
The goal of the game is to create a tile with a value of 2048.
|
|
|
|

Escape - exit the game
|
|
Backspace - undo last move
|
|

|
|
|
|
UP,LEFT,DOWN,RIGHT / W,A,S,D / touchscreen swipes - move the tiles
|
|
|
|
## Running instructions
|
|
|
|
Compile & run the game with `./v run examples/2048`
|
|
|
|
## Compiling to WASM
|
|
|
|
1. Install Emscripten from:
|
|
https://emscripten.org/docs/getting_started/downloads.html
|
|
|
|
2. Make sure that the environment in your shell is setup correctly,
|
|
i.e. that `emcc --version` works.
|
|
|
|
```sh
|
|
. /opt/emsdk/emsdk_env.sh
|
|
emcc --version
|
|
```
|
|
|
|
3. Compile the game to WASM:
|
|
(the JS file contains a loader for the .wasm file, without the extension):
|
|
```sh
|
|
v -prod -os wasm32_emscripten -o examples/2048/index.js examples/2048/
|
|
```
|
|
|
|
5. Run/test the game:
|
|
|
|
```sh
|
|
emrun examples/2048/index.html
|
|
```
|
|
|
|
If you prefer, instead of `emrun`, you can start a simple V http file server:
|
|
```sh
|
|
v -e 'import net.http.file; file.serve(folder: "examples/2048")'
|
|
```
|
|
and then open http://127.0.0.1:4001/ in your browser.
|
|
|
|
Once you have opened the game in your browser, you can make changes to
|
|
the V source, then recompile (step 3), and refresh the browser window
|
|
with the game, to see their effect.
