The Valley of adventure: Buggs report.

Post by XavSnap » Tue Jul 01, 2008 4:53 pm

Hi all!

This basic program seem difficult...
But, the programer use some constants to avoid to use numerics values.
When you use a numeric value, it take more memory: number string+5bytes.
In case of constant string, it take only the variable string space.

Constants:
O=0 ; H=1 ; H1=2 ; B=3 ; K=4 ; R=23

I found 2 buggs:
1/ The "Beware..." bug.
The F value returned by "3040 LET F=USR 17040", may be up to the last monster index.
You had to add:
3045 if F<=R-K-H then goto 3051
3050 LET F=INT (((R-K-H)*RND)+ H1)

... R-K-H =23-4-1 = 18 (Monsters)
First monster index is 2.
2/ The fist level tower "Zaexon's tower"
... I don't understand this code !!!

I also add the Ratings liste in 560... a long...long ... "Print" line.
550 LET XR= (...)+H1
560 Print at (...) ; "MONSTER FOOD" AND XR=0;"PEASANT" AND XR=0; (...)

Have fun!

I would like to hear more about this adventure. It sounds interesting. What type of game is it? Is it a text adventure? What is the general gameplay like?

Necropost-bump!

This game was a huge part of my early computing life, playing it first on the PET and then on the ZX81 after typing it in from the poster with my Dad.

As a new ZXpand owner, I've downloaded the above to have a play but found it's the un-corrected version, with bugs that cause the program to crash.I have a copy on tape of the fixed version from bitd, but I'm having trouble loading it :x Does anyone have a copy of the corrected version, or a link to the corrections?

On a side note, I've been trying to track a copy of the PET version down (from the Computing Today listing) but have had no luck. I'm resigned to typing that in :)

Had a thought to check through ZX Computing magazine :)

:D
Well done Fwapp !

I can debug it... 8 years after the type-in...
:oops:

[EDIT] ...I had to download it from my web site... :mrgreen:

No - thank you for posting in the first place :)

I've been desperate to play this for a very long time. I've been trying to get my own copy to load with no luck, and really did not fancy typing it in (again)!

The Valley was a large part of my early programming experience too. I converted the original PET listing to work on the ZX Spectrum.

I recently tracked down the original PET listing along with some conversions and enhancements if anyone is interested. I’ve long since lost my Soectrum listing.

I also did a version of Super Star Trek for the Spectrum but that’s been lost too!

Hey Dave - I'd love to see what you've got related to The Valley. I tracked down a copy of Computing Today with the original PET listing in, but have yet to type it into my PET.

This is the link to where I picked up the original PET listing and hints, tips and extensions

If you need further help, please let me know. I was thinking of gathering all my BASIC research material together on my website but haven’t got it organised yet!
