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

Note: Forum was not yet created

• Discuss the Open Eggbert project ( https://forum.openeggbert.com )
• To create free replacements for game assets
  • 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 behaves as much as possible as the original names 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

Goals

1. To specify and implement new features with comparison to Speedy Blupi I/II
2. To provide the ultimate specification of "Speedy Blupi/Eggbert Games".
   • This specification should be as sufficient as possible to recreate these games.
   • This specification should completely include all the details related to technical information for graphics, sounds, cheats, hacks, bugs, behaviours.
3. To create free replacements of game assets (MIDI music, WAV sounds, BMP graphics)
4. To record videos playing all levels and all possible situations.
5. To provide help how to run and modify Speedy Blupi/Eggbert (Exagear, Wine, Windows Phone emulation or rooting, etc.)
6. To list all important websites related to Speedy Blupi/Eggbert. See https://net.nanoboot.org/websites.jsp
7. To recreate Speedy Blupi/Eggbert games using Java programming language and the FXGL library.
   • Possible discussion for the technologies to be used is open.
   • Open Eggbert should be just one engine capable to be switched to behave like one of versions of the game. It will be possible to launch Open Eggbert in one of these 8 modes: Blupi Demo, Blupi I, Blupi II, Eggbert Demo, Eggbert 1, Eggbert 2, Phone, Open
   • It will be a very long way to develop "Open Eggbert", but I think, that the revival of these games is possible.
   • Source code is not available for any of Speedy Blupi/Eggbert games". This means, we cannot use these source codes to create a game like Speedy Blupi 3, but the recreation is the way.
8. To create the completely new graphic. Possible applications to be used for this task are Gimp, Inkscape, Blender and others.
   1. 3D models will be used to create the new prerendered sprites
   2. Game resolution will be 640*480 or 1280*960 (or another technical solution - to be discussed)
9. To create Open Eggbert 3. It means new features in the game.
10. Support for these platforms: Desktop(Windows, Linux, macOS), Web, Android, iOS

1. Recreation of game graphics (doubled resolution). New vehicles. Existing features will be improved.
2. Open Eggbert Editor - new separate application, an alternative level editor. Features will be inspired by X-Edit, X-Edit-Mapper and BlupiEdit and tiled-blupi
3. An alternative new Graphics - will be created and modeled probably with Blender and Gimp and Inkscape.
4. New directories:
   • IMAGE24 - 24 bit graphics (BMP or PNG)

    1. worlds in directory data (mandatory)
    2. alternative graphics in directories IMAGES08 or IMAGES16 or IMAGE24 OR IMAGES16X2 OR IMAGES24X2 (optional)
    3. alternative WAV sounds in directory SOUND
    4. alternative MIDI music in directory SOUND
17. Use of artificial intelligence - for example to simulate other players for multiplayer or to simulate gameplay by the computer or to generate new worlds

19. World size could be also: width=200 height=200
20. Infinite worlds - provided by the world generator
21. Limits will be changed: size and object limit in levels. This requires new file format - maybe EGT file name extension.
22. Dream blocks will be back

    • accelerometer (similar to the Windows Phone version) - available only on the Android version'
    • onscreen keyboard
32. New keyboard shortcuts:
    • F7: Speed 4x
    • F8: Speed 8x

iPhone

It is not planned for Open Eggbert to support the iPhone.

• But you can try set the source code level of Open Eggbert to Java 8, fix the issues and then add the iPhone support.

Name origin

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

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"
