Iter Vehemens Ad Necem

[DarkStar88]

My favorite roguelike game of all time, except for two little problems:

1. The savegame files are HUGE for such a simple game; an extended game can grow your save folder to hundreds of Megabytes. Since they compress to almost nothing I suspect the fault is with the game itself.

2. It is quite possible to overload the engine and permanently have attributes like 'invisible' or 'confused'. This can be quite a pain, especially the former as it means you can't trade with shopkeepers as they can't see you!

Could someone could give me a hand in finding where the game stores what in the save files? Even just being able to turn on/off the aforementioned attributes would be great - a full editor (add/remove items, change stats, etc.) would be icing on the cake.

EDIT: A basic course in IVAN's scripting. Well worth a read.

Nice to see the source is available for the game; I could probably track down the code that actually reads/writes the save files. I may look at this sometime, but not now - I've got too many other things going on ATM.

well game::Save (game.cpp, 770) makes the save:

it writes a bunch of player attributes,
the equipment,
attributes,
dungeons,
gods,
teams,
current level/wilderness,
other player stats

as a guess, the dungeons are huge.

edit

the states hold if you're invisible or not. these are handled with bitflags:

Code: Select all

#define STATES 20
#define INVISIBLE (1 << 6)

not sure where these states are stored with the player though

The dungeons themselves aren't that big, going by roguelike standards, but it probably seems that way due to how IVAN reads/writes the files.

Do states handle other attributes, such as teleporting or polymorphing?
