Legend:

* AOG SW - Aliens Of Gold (shareware)

* AOG - Aliens Of Gold (full)

* PS - Planet Strike

Both all lowercase and all uppercase (default) file names are supported.

The port auto-detect assets of some digital distribution services.

Supported services:

- [GOG](http://gog.com/)  

  Windows only.

- [Steam](http://store.steampowered.com)  

  Windows only.  

6 - Profile

===========

Configuration file, saved game files, etc. are stored in user's profile. The path to those files depends on platform. To override the path use `--profile_dir` option.

On Windows, the path might look like `C:\Users\john\AppData\Roaming\bibendovsky\bstone\`

On Linux, the path might look like `/home/john/.local/share/bibendovsky/bstone/`

On Mac OS X, the path might look like `/Users/john/Library/Application Support/bibendovsky/bstone/`

Configuration file name: `bstone_config`  

Log file name: `bstone_log.txt`  

High scores file name: `bstone__high_scores`  

Saved game file name: `bstone__saved_game`

Where `` is:

* `aog_sw` - Aliens Of Gold (shareware)

* `aog_full` - Aliens Of Gold (full)

* `ps` - Planet Strike

7 - Audio

=========

Provides default stereo driver and optional 3D one.  

Use option `GAME OPTIONS - SOUND - DRIVER` to change the driver.

7.1 - OpenAL driver

===================

Supports any OpenAL v1.1 compatible implementation (Creative Labs, OpenAL Soft, etc.).  

Implementation driver should be available system wide (i.e., via `oalinst.exe`) or should be placed along with port's binary.  

Expected driver name is `OpenAL32.dll` on Windows or `libopenal.so` on non-Windows system.  

Set configuration string `snd_oal_library` to use another name.

The port uses default device name.  

Set configuration string `snd_oal_device_name` to open specific device.

8 - External textures

=====================

Allows to replace stocked textures with custom ones.

Supported targets: wall, sprite, flooring, ceiling.

Option `GAME OPTIONS - VIDEO - TEXTURING - EXTERNAL TEXTURES` enables or disables them on the fly.  

WARNING Changing the option may take some time if the dimensions of loaded textures are high.

8.1 - Aspect ratio

==================

Both vanilla games ran only in a 320x200 video mode. On monitors, widely available at the time, this video mode took up the entire screen, which had a 4:3 physical aspect ratio. This meant that the 320x200 display, with a 16:10 logical ratio, was stretched vertically - each pixel was 20% taller than it was wide.

In-game graphics have been specifically designed for the 320x200 resolution as stretched to a 4:3 physical aspect ratio.

The port stretches the geometry (world, objects) vertically by 20%.

That means if you created a wall or sprite texture, for example, with physical dimensions 1024x1024 it will be rendered as 1024x1228, i.e. stretched.

Flooring and ceiling textures has always 1:1 aspect ratio.

TLDR

- Design wall, sprite, HUD element or screen images in 1:1.2 aspect ratio (i.e. 1280x1536), but export for the game in 1:1 aspect ratio (i.e. 1024x1024).

- Design flooring or ceiling image in 1:1 aspect ratio (i.e. 1280x1280), and export for the game in 1:1 aspect ratio (i.e. 1024x1024) too.

8.2 - Transparency

==================

Images with alpha channel should be exported as [*premultiplied*](http://en.wikipedia.org/wiki/Alpha_compositing).

8.3 - Naming conventions

========================

All letters *should be* lower case.

"Aliens Of Gold" resources are goes into `aog` directory.

"Planet Strike" resources are goes into `ps` directory.

Sprite name format: `sprite_xxxxxxxx.ext`.

Wall name format: `wall_xxxxxxxx.ext`.

Where:

- `xxxxxxxx` - an internal decimal number of the sprite padded with zero on the left. For "Aliens Of Gold" those internal numbers are based on version `2.1`.

- `.ext` - file name extension.

Examples:

- `aog/sprite_00000034.bmp` - "Aliens Of Gold" yellow key card sprite in BMP format.

- `aog/wall_00000088.png` - "Aliens Of Gold" turned on south-north switch wall in PNG format.

8.4 - Supported file formats

============================

8.5 -  File format search order

10.1 - Generic instructions for Linux-based system or build environment (MinGW)

=============================================================================

1. Install minimum required software described above.

2. Obtain source code and extract it (if necessary) into some directory. For our example we will use working directory `~/bstone-x.y.z`.

3. Make directory `~/bstone-x.y.z/build` current.

4. Generate Makefile.  

`cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=~/bstone-x.y.z/build/install ..`

5. Build and install:

`cmake --build . --target install`

6. On success you will find executable and text files in the directory `~/bstone-x.y.z/build/install`.
