# Invaders Resurrection
Bringing life back to a space invaders game from 1999.
Overall TODO list is kept in [plan.org](plan.org).
## Building
The build system is using plain GNU Make (developed using version 4.3).
Make sure that SDL 2.x is installed.
Consult http://www.libsdl.org/ or your Linux distributions package manager.
Build invaders as follows:
make exe/invaders
Currently there is no install target.
Launch the game directly from the build directory.
_out/host/bin/invaders
### Build Options
The following build options are supported by the GNU make based build system.
| Argument | Description |
|--------------------|------------------------------------------|
| V=1 or VERBOSE=1 | Output full compilation commands |
| VARIANT=release | Optimization |
| VARIANT=debug | No optimization and debug info (default) |
| VARIANT=debug-asan | Debug with address sanitizer |
### emscripten
Steps for building invaders using emscripten.
NOTE: Building with emscripten is work in progress. SDL initialization currently fails at run time.
Install emscripten core as described at https://emscripten.org/docs/getting_started/downloads.html.
Create a directory for installing emscripten compiled libraries:
```bash
mkdir .../emscripten
```
Build zlib:
```bash
git clone https://github.com/emscripten-ports/zlib .../zlib
cd .../zlib
emconfigure ./configure --prefix=/opt/emscripten --static
emmake make install
```
Build SDL:
```bash
git clone --depth 1 --branch release-2.30.7 https://github.com/libsdl-org/SDL .../SDL-2.30.7
cd .../SDL-2.30.7
emconfigure ./configure --prefix=/opt/emscripten --disable-pthreads --enable-static --disable-shared
emmake make -j8
emmake make install
```
Build invaders:
```bash
NO_THREADS=1 LDFLAGS="-sLEGACY_GL_EMULATION" EM_PKG_CONFIG_PATH=/opt/emscripten/lib/pkgconfig emmake make -j8 VARIANT=release exe/invaders
```
## Input
Keys to use in the game:
| Key | Action |
|----------|-------------------------------------------|
| SPACE | Fire |
| ESCAPE | Quit |
| A, LEFT | Turn left |
