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:

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_<game>_high_scores
Saved game file name: bstone_<game>_saved_game

Where <game> 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.

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

  1. PNG
  2. BMP

9 - Taking screenshots

Default key is F5.
Use menu to modify bindings.

Taken screenshots are placed in the profile directory.

Supported format: PNG

10 - Compiling

Minimum requirements:

CMake variables:

  • CMAKE_BUILD_TYPE
    Selects which build(s) to compile. Use semicolon to separate entries. Usually it's Release. For other values see CMake documentation.

  • CMAKE_INSTALL_PREFIX
    Selects location where to install files to.

  • BSTONE_PANDORA
    Enables build for Open Pandora.

  • BSTONE_USE_PCH
    If enabled utilizes precompiled headers to speed up the compilation.

  • BSTONE_USE_STATIC_LINKING
    If enabled links modules statically to avoid dependency on system and custom libraries at run-time.

  • BSTONE_USE_MULTI_PROCESS_COMPILATION
    Enables multi-process compilation if supported.

  • BSTONE_MORE_COMPILER_WARNINGS
    Enables more compilation warnings.

  • BSTONE_TESTS
    Builds and installs an application to test internal facility.
    Default value: OFF

  • BSTONE_TRIM_FILE_PATHS_IN_EXE
    Makes file paths in the executable relative to the source code directory.
    Default value: OFF

  • SDL2W_SDL2_DIR
    Defines directory with SDL2 CMake configuration file or with official SDL2 development Windows build.

  • BSTONE_INTERNAL_SDL2
    Enables bundled SDL2 source code.
    Default value: OFF

Notes:

  • Use ON value to enable option and value OFF to disable option.

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.
