This time I'm going to show you screenshots of all levels of the Amiga version of my Robot R-29 game and the entire source code. Let's start from the title screen and the first five original levels. A little translation may be needed: życia - lives; punkty - score; plansza - level.
The title screen |
Level 1 |
Level 2 |
Level 3 |
Level 4 |
Level 5 |
As I said earlier, there were only these five levels in the original source code in the Atari magazine in which it was published. I decided to add a few features to make the game more interesting, and at the same time I also designed some new levels. And here they are. Four entirely unique new levels.
Level 6 |
Level 7 |
Level 8 |
Level 9 |
Game over screen |
Congratulations screen |
The Amiga Amos was a pretty good implementation of Basic, especially for that time. Although it was an interpreter, its performance was actually pretty good and allowed to write some decent game (for Basic on a 16-bit computer). There is also a compiler available, however I never had a chance to use one back then. Here's a screenshot of the Amos Creator environment, pressing Escape switches from editor to direct mode where one can execute almost any instruction.
The beginning of the source in Amos editor |
And lastly, the source code. If anybody's interested I'll gladly publish a translated version, with variable names and comments all in English language. At the end of the file you'll see level map definitions where different characters represent different elements of each level.
- @ - wall
- A, B, C, D - the robot looking at different directions (up, down, left and right)
- F - spanner
- E - bomb
- G - magnet
- H - magnetic field
- I - electric field
- J - land mine
- K - exit
