Desktop Obstacle Engine (DoE) - 11/28/19 14:06


I wanted to share a old and groovy app written by myself 2012.

Its a Desktop obstacle Engine that allows you to have your favourite sprites running on your Desktop.
Windows will be used as "2D Level" for the sprites.

Maybe some still remember the old Windows 3.11 Sheep ? Well this is the next Level of this great app. laugh

The sleeping sheep ... how cute

If iam right the original sheep sprite was made by Tatsutoshi Nomura, sry if i gave wrong credits at this point

Use your own sprites! DoE comes with Sheep, Super Mario (SNES) and Max (Sam and Max) examples
You can use Bitmaps (BMP) or animated GIF files ( "unlimited" animation sprites with gif )

App is with german text now, if enough people care, ill make a english Version of it. Or completly rewrite it from scratch.
Project is pretty beta but (almost) bug free so far. it was a fun test project.
its all very easy to use
BUT readme.txt (with some good Infos) is both, german and english.

Adjust movement values to your need

DoE works without Installation or admin rights. Simply double click on the exe file, thats all.
Windows is full useable (no screensaver style). You can interact with sprites if u want (drag and drop).
Right click on sprite for a popup menu (because minimized app wnd is invisible).

Download link (1.24MB ZIP file - password: doe):

Download works, anyway...maybe a better link follows, if i get some private server web space.


Main states / animations featured:
- Walk left / right
- Fast fly from screen top to bottom ( burning sheep )
- Crash floor / crash into windows left / right side ( while flying )
- Idle ( eat flower ) whatever
- Sprite object ( flower )
- Fall down
- Climb up ( build steps with windows ) / drag
- App was opened / closed ( for example sheep gets big eyes )
- Another sprite moving from right to left side of Screen ( grey sheep )
- Randomly flying sprite over Screen ( Ufo )
- Sleep
- Wake up
- ...

edit end

Have fun with this nice app

Small bug found frown

If two screens are used in Windows, the black sheep starts visible on Desktop and wont move. You can simply click here to solve this issue:

If you launch the app with param "/versteckt" DoE starts with invisible main window (only sheep visible at startup).
Example: doe.exe /versteckt

Small demo vid:

Maybe this weekend i will upload a new version, but only with some small bug fixes and features.
English text and working taskbar+flying - objects, if two screens are used in Windows.

If i have enough time / and fun i also want the sheep to awake, if the window it sits on is closed/minimized/moved.
Let's see.

Started to rewrite all from scratch. Maybe ill finish it. Its like the science version of DoE. working title is DoE 2020.
Sprites are now dynamicly created at runtime with behaviour / event script (small script language for unique screen behaviour) etc.
For example a single DoE app can handle more than one moving sprite at once now.

Features already working
() "unlimited" moving sprites / skin files in one DoE
of course not that many sprites can be moved at once with a good framerate. please keep in mind
the Windows Desktop isnt a game engine wink ...for mass moving i would have to rewrite it a third time grin

rewritten it a third time grin
() much better "framerate"
() unlimited frames (GIF)
() "unlimited" size of sprites
() realtime gravity ( if apply_gravity is used ) in all anims
() very simple script language for unique sprite behaviour <- all gone into Editor (faster and more easy)
() syntax highlight of skin def file
() autostart of unlimited unique skin files on startup
() interaction between skin files / sprites
() english text
() click and play / fast edit of skin files
() smooth drag and drop of moving sprites
() clean anims, no switching errors anymore
() hotkey to show hidden app
() sidescroller (optional with gravity), topdown and flying (optional with wnd-bouncing) style movement
() background / level drawing
() bullets / shooting spritemovers
() sounds

Small wip Videos
edit: Meanwhile a lot of stuff was added, video is outdated already, but flow didnt change much
