# RTS (working title)

## Overview

**RTS** is a cross-platform, sprite-based real-time strategy video game
in the likes of several other entries from the mid 90's.

**The game is under heavy development, and very far from being playable.**

## Platforms

The following platforms are either supported or support is expected in
the future:

- **(supported)** Sony PlayStation 1, using a forked version of
[PSXSDK](https://git.disroot.org/xavi92/psxsdk).
- *(not supported yet)* Microsoft Win9x, using a `i386-mingw32`
cross-toolchain and SDL-1.2.
- *(not supported yet)* Modern Unix-like operating systems such as
GNU/Linux or *BSD, using SDL-1.2 (if available). Possibly modern
Microsoft Windows versions, too.

## Design goals

- Keep source code as simple and clean as possible.
- Keep platform-specific code separated so common code can be shared
between platforms without modifications.
- Use C99 features for better portability.
- Use modern CMake features for a simplified build process and
availability of the `compile_commands.json` database.
- Implement any multiplayer capabilities provided by the platform.
- And, above all, provide a fun game that can run even on low-end
hardware.

## Building from source

**RTS** can be built using the typical CMake build process. The
following options can be defined:

- `PS1_BUILD`: builds for Sony Playstation 1
- `HOST_BUILD`: builds for the host operating system using SDL-1.2
- `WIN9X_BUILD`: builds for Microsoft Win9x operating systems using
SDL-1.2. A `i386-mingw32` cross-toolchain must be available.

For example, the Sony PlayStation 1 version can be built using:

```
mkdir build && cd $_
cmake .. -DPS1_BUILD=1 -DVIDEO_MODE=VMODE_PAL -DCMAKE_EXPORT_COMPILE_COMMANDS=1
make -j$(nproc --all)
```

This will generate a `.bin`/`.cue` file pair in `build` that can be
played on an emulator or burnt into a CD-r in order to play the game
on real hardware.
