Found on a facebook BASIC Programming Language Public Group | FacebookA link to video Tiny Adventure 10 Line Basic Game Ported to Atari from ZX81
code from the link (ATARI BASIC) 1 DIM X$(150):X$=" CANNOT DOYOU WALK OPENED CLOSED A SWORD A KEY NOTHING A CHEST A DRAGON A CORPSE "
2 DIM U$(15),L$(20):LET R=1:LET C=0:LET I=0:X$(LEN(X$)+1)="TAKEN YOU DIED YOU WON. "
3 LET L$="CAVEPIT HALLLAKE":PRINT "YOU ARE IN A ";L$(R*4-3,R*4):INPUT U$
4 M=2*(U$="NORTH")*(R<3)-2*(U$="SOUTH")*(R>2)+(R=2 AND U$="WEST")-(R=3 AND U$="EAST")
5 LET A=(3+C+2*(I=2))*(R=2 AND U$="LOOK CHEST")+(11+(I=2))*(R=3 AND U$="KILL DRAGON")+(M<>0)
6 LET A=A+(5+R)*(U$="LOOK")+(6-I)*(U$="INVENTORY")+(6-(I=0))*(R=4 AND U$="LOOK CORPSE")
7 LET B=100*R+10*C+I:A=A+10*(B=400 AND U$="GET KEY")+2*(B=201 AND U$="OPEN CHEST")+10*(B=211 AND U$="GET SWORD")
8 LET R=R+M:C=C+(A=2):I=I+(A=10)
9 PRINT "> ";U$:? X$(A*9+4,A*9+12)
10 IF A<11 THEN GOTO 3Of cource it doesn't compile in LB. So, as Judge Dredd put it: |

Wow! Really cool.
I started on this before I realized it was WAY past my bedtime. So, this code doesn't work, but it does break down the functions in LB terms and replaces the oddly spaced words with comma-delimited phrases referenced using the WORD$ command, but I didn't get to reworking the formulas to calculate the word positions instead of the string length positions.
I'm going to bed! {|@() <== Yawning.

The interesting thing is - we see in code
* locations
* commands
* responses
But there do they store the MAZE?
(BTW with minor modification via MID$() it happen to run as is, with counted spaces, just fine)

The maze is in the layout of the locations is it not? A few changes to the string slicing of L$ and X$ gets it running.
1 X$=" CANNOT DOYOU WALK OPENED CLOSED A SWORD A KEY NOTHING A CHEST A DRAGON A CORPSE "
2 dim U$(15),L$(20):R=1:C=0:I=0:X$=X$+"TAKEN YOU DIED YOU WON. "
3 L$="CAVEPIT HALLLAKE":PRINT "YOU ARE IN A ";mid$(L$,R*4-3,4):INPUT U$
4 M=2*(U$="NORTH")*(R<3)-2*(U$="SOUTH")*(R>2)+(R=2 AND U$="WEST")-(R=3 AND U$="EAST")
5 A=(3+C+2*(I=2))*(R=2 AND U$="LOOK CHEST")+(11+(I=2))*(R=3 AND U$="KILL DRAGON")+(M<>0)
6 A=A+(5+R)*(U$="LOOK")+(6-I)*(U$="INVENTORY")+(6-(I=0))*(R=4 AND U$="LOOK CORPSE")
7 B=100*R+10*C+I:A=A+10*(B=400 AND U$="GET KEY")+2*(B=201 AND U$="OPEN CHEST")+10*(B=211 AND U$="GET SWORD")
8 R=R+M:C=C+(A=2):I=I+(A=10)
9 PRINT "> ";U$;"?";mid$(X$,(A*9)+4,9)
10 IF A<11 THEN GOTO 3

Sure, but it's sloppy and contrived; limited by Atari's odd restrictions. If the goal is to just get the code to work in LB, that's cool.

Yes, and so obfuscated it’s pretty useless for anything other than it is. A neat little adventure engine would be cool. Something folks can understand and expand.

You posted a link about a video that I posted about from the BASIC language Facebook group that I moderate.  You didn't realize that is one of my Facebook groups? |

Classic text based adventures. I have a couple of old projects that need rescuing. But making it visual and interactive enough for modern users! I had a plan once, it was for an interactive book. The text was supposed to change depending on choices. Must pull it out the drawer.

I think so. Did it use simple text blocks to draw maps and list stats on the right side? I think I played it on a Kaypro back in high school around '83. Fun game as I recall.
:@)

How you think I found it?
Tried to find group you mentioned
(and until I mentioned your name I could not find anything)
No, I had no idea who posted that link.
For me all that stuff on a group page looks totally unstructured, I will hardly ever visit it again.

Fun game as I recall. :@) There probably was a CP/M version as you describe. The one I played is for the C64 and has some simple color graphics and atmospheric music. It is written in BASIC. |
