## Dependencies

- [Git](https://git-scm.com): for version control
- [Standard C++ compiler](https://en.wikipedia.org/wiki/List_of_compilers#cite_ref-15) conforming to C++17 and above standards: to build the project locally (tested on gcc12.0 and clang 13.0)
- [Emscripten](https://emscripten.org) : to compile the program to WebAsm
- [SDL2.0 library](https://github.com/libsdl-org/SDL) :for rendering stuff on screen.
- [SDL TTF library](https://github.com/libsdl-org/SDL_ttf) : for rendering font from TrueType (.ttf) font files.
- [SDL Mixer library](https://github.com/libsdl-org/SDL_mixer) : for playing music and sounds.

## Build instructions

Perform the following steps to build the project on your native machine:

1. Clone/download the repository:

```sh
git clone https://github.com/Arsenic-ATG/Tetris
```

1. Now compile the program (depending on whether you want to build the online deployable version or native build, follow one of the following steps):

3.1. **WebAsm build using emscripten** :

To build the online deployable version of the game, we would be using `emscripten` to compile the program to webasm.

```sh
    make setup-emsdk
    ```

```sh
    make activate-emsdk
    ```

```sh
    make build
    ```

- The build files should be in [`build`](./build) subdirectory of the repository
    - Once in build directory, you can simply use `emrun` to run the HTML pages via a locally launched web server.

```sh
    make serve
    ```

FWIW: you may also like to visit [emscripten documentation](https://emscripten.org/docs/compiling/Building-Projects.html#building-projects) regarding more info about building a project with emscripten if you are interesting to know more about the same.

3.2. **Native build using native C++ compiler** :

- Just use your native C++ compiler to build and executable from all the source files (order in which they should be provided to the command should not matter in most cases )

- Make sure to link `SDL2`, `SDL2_ttf` and `SDL2_mixer` libraries properly.

```sh
    make build-g++
    ```

- run the built executable.

```sh
    chmod +x ./a.out
    ./a.out
    ```

These instructions are meant to be understood by developers of every level, so if you are unable to understand anything or face any difficulty in building the project then make sure to complaint about the same by opening an issue or in discuss section.
