variant programming - broken savefiles - help!

[Guest]

Archived from groups: rec.games.roguelike.angband (More info?)

I'm working on a variant based on V.

I didn't change anything to monsters or load.c

However, when I change the version number in defines.h, it says...

"too many (8192) monsters" and then "broken savefile"

Unless I can fix this my variant will forever be version 3.0.5 ...

It breathes confusion -more-

I think it is either one of two things.....

That error message usually means the game ha saved a piece of data as one variable size, but is trying to read it as another size, such as writing a byte sized piece of information, then reading it as an integer, so it read part of the next price of information, and the savefile breaks from there. Start at where the error message is checked for and displayed, and work backwards in load.c, comparing it to save.c. It probably isn't more than a couple lines of code away.

The other possibility is that a string is being terminated properly when being saved, or isn't long enough, so the load file is reading too much data when trying to read that string.

At least that's what was happening to me when I was getting those errors. I hope that helps, and good luck,

-Jeff

Ok, now I took a fresh copy of V 3.0.5 and just changed the version number to
1.0.0

It gives me the same error.

Increasing the version to 4.0.5 works, so I'm thinking backwards compatibility
code.

Sadly, chopping out anything using older_than() didn't fix it.

Now what?

Are you sure that you removed the older_than() calls correctly? I just
tried the version number change and had no problems. Watch out for the
'else' branches for the 'if (older_than(...))' and 'if (!older_than(...))'
checks. Especially the later one can by tricky. If you don't keep the
correct branches then you'll get errors.

YES! That's it, I was tricked by an if (!older_than).

Thank you. Now I'm mere hours away from a test version.
