Introduction

This is original image of Open Eggbert created by Robert Vokáč

Open Eggbert is a free and open-source recreation of Speedy Blupi I/II computer game.

Multiple platforms are supported: Windows, Linux, MacOS, Android, Web (via GWT)

Relation to Speedy Blupi

Open Eggbert is an approximation of the Speedy Blupi engine.

Open Eggbert does not have a Clock cycle wise identical behaviour as Speedy Blupi, because to reach such goal is not possible without the source code of Speedy Blupi engine.

However, the player should not be able find out, whether he is playing Speedy Blupi game created by Daniel Roux or Open Eggbert (the reimplementation)

Why Open Eggbert was created

  • Both the games Speedy Blupi I and Speedy Blupi II are closed-source.
  • Modifications of Speedy Blupi are possible only by hex editing of the EXE files
  • Bugs in Speedy Blupi cannot be fixed
  • Existing features of Speedy Blupi cannot be improved
  • New features cannot be added to Speedy Blupi
  • No one has yet appeared to start a project to create a recreation (reimplementation) of Speedy Blupi I/2.

Advantages of Open Eggbert

New features can be added. Existing features can be improved. Found bugs can be fixed. Game can be ported to new platforms.

Notes

  1. Open Eggbert is specifically focused on recreating Speedy Blupi/Eggbert games. This does not include other Blupi games.
  2. Open Eggbert does not plan to support iPhone. Reason: iPhone via RoboVM supports only Java 8. But you can try compile Open Eggbert with Java 8 and then add iPhone support.

Forum

https://forum.openeggbert.com

  • Discuss the Open Eggbert project

Create free replacements for game assets (like MIDI music, WAV sounds, BMP graphics)

  • MIDI music, WAV sounds, BMP graphics
  • Applications like Gimp, Inkscape and Blender can be used to achieve these goals
  • 3D sprites for Speedy Blupi were created using the Ray Dream Studio 3D application
  • Music for Speedy Blupi was created using the Microsoft Music Producer application
  • Sounds - Original sounds may be the own recordings of the voice of Daniel Roux

Game space

Game space is a directory with the defined structure.

Player has one or more game spaces.

Each game space has a feature level.

Game space can be cloned. You can have several game spaces with the same Feature level.

Feature level

Feature level represents set of features, which are supported in the given game space.

Open Eggbert behaves almost exactly like the original game version related to the Feature level.

Feature levels:

  1. Speedy Blupi Demo
  2. Speedy Blupi I
  3. Speedy Blupi II
  4. Speedy Eggbert Demo
  5. Speedy Eggbert VALUEWARE
  6. Speedy Eggbert 1
  7. Speedy Eggbert 2
  8. Open Eggbert 3 - new features, which are not available in the original games developed by Daniel Roux

Legacy mode

If legacy mode is enabled in CONFIG.DEF, then Open Eggbert will behave as much as possible as the original games developed by Daniel Roux.

If legacy mode is disabled, then all Open Eggbert new features, graphics, sounds, music, etc. of Open Eggbert will be present and activated

The third possibility is to set the value of LegacyMode, which contains comma separated list of Open Eggbert only features, which will be additionally activated and supported. This means, that Legacy mode is enabled, but some Open Eggbert only features are activated.

  • For example disable cheat, even the game behaves like Speedy Eggbert I

Name origin

Its name is not "Open Blupi", because "Blupi" is the registered trademark of Epsitec company.[1]

Open is the first word in the name, because Open Eggbert is open-source.

Speedy Eggbert is no more a registred trademark and this is reason, why the second word in the name is "Eggbert"
