Here's my entry…
The moon landing from Collins' perspective
there's still room for improvements…
Use arrow Keys to move the module, spacebar to throttle.
Even horizontal movement uses fuel. Don't waste the fuel.

I didn't realize that my coding style wasted huge amount of bytes :)

Thank you.
I think I can squeeze other bytes and add some feature.
It's a funny contest.

sleep 20,1 needs to be outside screenlock / screenunlock for your code to work properly on my (linux) system.

But horizontal movement is still possible without fuel :-)

The contest happened during my camping trip. Luckily there is no deadline, so I'll try to make something this week. A bit worried about the 4K limit.

Much as I like UEZ's and Pitto's contributions, I don't think contestants should shower praise on each other.
Rather, they should root out bugs in each other's code.
But D.J.Peters is the boss of this thread, so he has the say.
Hope you managed to avoid pneumonia badidea.

Same here 'stupid rule' ;-)
after I got my polygon filler down under 1 K
it's hard for me to get the sound output for Windows and Linux, (yes I'm positive crazy but I name it "creative")
the 3d stuff and the game code it self in the rest of the 3K !
I know there isn't sound in vacuum space but hey it's fun.

I'm working on it, not often but from time to time !
Two times I deleted all and began from zero again.

here are: "1st place in PC 4k compo at Breakpoint 2009"
youtube: https://www.youtube.com/watch?v=jB0vBmiTr6o

here are the slides how it was made in 4K

I was thinking about making some simulation of the Apollo missions from Earth launch to re-entry. But it was a pretty complex procedure:
https://en.wikipedia.org/wiki/Apollo_pr ... on_profile
Two rocket stages are discarded within 11 minutes, a 3rd stage a bit later when traveling closer to the moon. One part (CSM) with 1 person stayed in moon orbit while 2 other persons landed on moon with the lunar module (LM). LM goes back to CSM, leaving stuff behind on the moon. Then fly back to Earth leaving the LM to crash back of the moon. Then before Earth re-entry leaving more stuff behind, the 3 persons drop to Earth in a very tiny thing compared to whole machine launched initially. There is a 14-story high building near my house which is, I think, pretty big. The complete Saturn V is 2.5 times as high. Pretty crazy, who would volunteer to sit in the top of this fuel filled thing?

Yes jet fighters in this day's was sitting near the turbine engines and the rockets on the wings !

They are the right persons for this crazy mission ;-)

My first idea was a "Lunar Roving Vehicle" game on the moon with low gravity (what a fun)
but it was later in 1971 Apollo 15-17, damned :-)

I got Windows and Linux sound output under 1K each.

That's one small step for man, one giant leap for my mini game :-)

Here are the windows part 910 bytes I post it only for fun how the hand compressed BASIC looks.
It includes all what sample playback needs
sample buffer fill thread
device message callback
mutex and conditions
wave format definition
wave header allocation
sample buffer allocation
and many fun
...

Let me know if you will see how it looks decompressed or if you like to use it in your own next game or demo.

After I wrote the Windows MME, Directsound and dsp, arts and Alsa Linux driver for FBSound
I self never thinking I can get it in 15 lines of code,
it's fun if you surprise yourself.

Land It - a primitiv game where you have to land the shuttle on a flat ground.

Arrow keys to steer shuttle (yellow). You must land less than 0.5 speed. Press Enter to start and Q to exit game. When "Game over" is displayed, press R to restart.

@UEZ Nice and tiny "old school" I like it.

But a little bit hard to play here !
Your main loop run's at ~100 Hz. (sleep 10,1)
if you press a key Multikey() is really fast so the keydown event are to long here.

I added a frame counter and use Multikey() at 25Hz now it's playable here.

Joshy

Code: Select all

If (fuel>0) andalso (frames mod 4=0) Then
  If Multikey(SC_LEFT)  Then SS.vx-=0.1 :fuel-=1 :Line (SS.x+11,SS.y+8 )-(SS.x+16,SS.y+12),r,BF
  If Multikey(SC_RIGHT) Then SS.vx+=0.1 :fuel-=1 :Line (SS.x- 6,SS.y+ 8)-(SS.x- 1,SS.y+12),r,BF
  If Multikey(SC_Up)    Then SS.vy-=0.05:fuel-=10:Line (SS.x+ 3,SS.y+21)-(SS.x+ 7,SS.y+26),r,BF
  If Multikey(SC_Down)  Then SS.vy+=0.05:fuel-=10:Line (SS.x+ 3,SS.y- 6)-(SS.x+ 7,SS.y -1),r,BF
Else
  Draw String (420,200),"Out of fuel. Game Over!":go=1:p=1
End If
