I was pretty bored today, so I decided to do something sooo stupid that I knew it would never get into DROD otherwise:

I made it output a room as a text file.

The text output is formatted as follows (this is an example):

OLAYER:
WWWWWWWWWWWWWWWWWWWWWWWWWWWW
W               O          W
W               O          W
W               O          W
G               O          W
WWWWWWWWWWWWWWWWWWWWWWWWWWWW

TLAYER:
                            
                       O    
                            
                            
                            
                            

MLAYER:
                            
 RRRRRRRRRRRR                
 RRRRRRRRRRRR                
 RRRRRRRRRRRR                
 RRRRRRRRRRRR                
                             

ORIENTATIONS:
44444444444444444444444444444
46666666666664444444444444444
46666666666664444444444444444
46666666666664444444444444444
46666666666664444444444444444
44444444444444444444444444444

ORBDATA:
2,5:2,8,2;5,23,1;

SCROLLDATA:
5,6:Hello, this is DROD at your service


OLAYER,TLAYER, and MLAYER represent the object on the respective layer. ORIENTATION contains the orientation of the object:
012
345
678

ORBDATA has one line per orb in the room, consisting of comma-seperated x and y values for the orb, followed by a colon, and comman-seperated x, y, and effect values for each door affected (effect is 1 for toggle, 2 for open, 3 for close). Each of these are seperated by a semicolon.

SCROLLDATA has a starting line for each scroll in the room, that is labeled with comma-seperated x and y values, followed by a colon. After that is the data from the scroll, terminated by the string "?%?" (this is in case of multi=line scrolls, so that a parser would know when to stop). On the next line is the next scroll.

Scripting could be handled with the upcoming script-to-text parser, and could easily be added to the end. The rest of the data is not of consequence (stairs would theoretically be automatically assigned to end hold, because when modifying rooms like this, it would be too unreliable). Entrances would not be stored at all (although there is a character for Beethro).

I won't bother saying here what all the characters are, because I have yet to add any sort of interface to the function, or to write the inverse (that turns the string into a room). As would be expected, the function is untested (due to my inability to actually get DROD to boot up when I compile it). Don't worry though, I already ironed out the errors. The modified files (DbRooms.h, DbRooms.cpp, TileConstants.h) are included here.

Oh, and in case it wasn't obvious from the files, they're under the MPL (apparently I'm supposed to say that here).

Oh, and can someone please tell me where TILE_MID is defined? I seem to have lost it!

That sounds pretty handy, actually... I dislike having to type all those orbs by hand when using an orb solver, and perhaps you could use the same sort of thing for other programs. I *want* an AI that can learn playing DROD!

Actually, if you made a simple function:

ostream& operator<< (ostream& o, const CDbRoom& Room){
o<<Room.GetText();
return o;
}

Then it would be trivial to add a hotkey to output the current room's status via filestream.

It can looks like a DROD but accept command from console and dump loaded rooms/levels.

Thats the problem. Caravel will not support any binary mods, and so Id have to work on a separate utility in order to get something like this to work. For that, Id have to have a working compilation, and probably Id need to get DRODUtil up and working. So, for the time being, all you can do is cross your fingers and hope Mike puts this in somewhere.

More accurately, I believe (as in "I seem to remember") Caravel Games does not support binary mods on these boards, but has otherwise nothing against their existence. So, so long as said mod is kept outside those forums, it should be fine (the rationale was, more or less, "avoiding a bunch of problems with users toying with binary mods that make the whole thing go fubar"... which seems pretty reasonable, in my limited experience as makeshift hotline).

I'm not sure if that would be the case for a binary mod that prevents normal Drod play, or even a wholly different executable compiled from source. In the latter case, you would be missing CaravelNet (not a big deal here) and some content (not a big deal either, and "copy-paste" should be able to solve that). I don't think a separate executable has been offered for download here yet.

Of course, I'm not in any way or manner affiliated with Caravel Games, the opinions presented here are not endorsed by my current employer, university, or spouse, no warranties, massive disclaimers of irresponsibility, and nobody is pulling any strings. Nope.

Well, what they said is that they have nothing against them, but they wont support them. Ergo, if youre using a binary mod, then you better be prepared to remove it before you go crawling to them for help. And for simplicity reasons, Im reluctant to hand out a full executable. Now, as I said, a utility to fetch rooms from a hold might be nice, but that is a future endeavor. Right now its just an exercise of the mind. Once The City Beneath is out, I might be more willing to try and get this working, but for now, I think the term pipe dream would be very appropriate.

Yes, there's a big difference between a mod you use to play the game, and a utility that happens to take the form of a mod. Especially if the utility prevents playing. I'm not Caravel either, but I don't see why they'd have a problem?

Anyway, the simplest way by far to do this room-to-text thing would be to modify the source. Everything you need (and you need rather a lot to get to the point where you can work with room data) is there. Plus you already have an interface. Add coppro's code and hijack a button on the restore screen. You click restore and instead of restoring, it dumps the room as text. (To some location specified in a text file somewhere, or if you feel like it, use the framework already included to pop up a dialog or something.)

Writing this from scratch or extracting only what you need is a major hassle. (I know, because I tried, when recovering progress from CNet for someone. In the end it was far easier to simply use the full source with a few changes.) Of course, if you feel like taking on a project, that's different, but if you have some utility in mind, and you want to get the job done, modifying the full source is the way to go. The only drawback is that the .exe then contains a lot of stuff you don't need, so it's unnecessarily large. Maybe I'm just lazy.

I think the main issue is that Mike doesn't want to have to inspect the mod carefully in order to ensure that:

A - it has no hidden gameplay affecting features (or in this case, any hidden backdoors to the gameplay or something like that).
and B - it introduces no potentially serious bugs.

It's not about what a mod can or cannot do, it's about the fact that anything appearing on these forums can be taken to be not only tolerated but rather endorsed by Caravel, and it saves a lot of potential headaches to only have official support for the official development branch.

I'm not saying they're above making exceptions, especially in cases like this, but I think having a very strict policy makes sense.

Just for the sake of clarity, Eytanz: your post only applies to binary mods, right? Or would Caravel Games ask for the non-distribution of separate executables on their boards as well?

Coppro: I could be interested in making said executable, one of those days when I'm feeling insomniac... The thought of having to glance at C++ code to do the actual changes doesn't appeal to me, though. I know I want to add an "export player file" command-line flag to Drod, though I can't work up enough will to hack through the code.

There might be *some* use for some sort of shebang "a bunch of little features thrown in DROD, with no apparant design or concertation, all packed up in a new executable". Or perhaps not.

I'm not entirely sure what the policy actually is. You'll have to ask Mike or Erik. I was just pointing out that Caravel has a reason to disallow mods, even if they don't directly affect gameplay.

Since I already had most of the code written for something like this, I quickly whipped together a program that dumps a room as text from a hold file.

Usage (case sensitive):
java VerboseHold <Hold file> <LevelID> <RoomX> <RoomY>
This will dump the room in a similar format to the one above. You will need to know the internal LevelID for the level the room is on. This information can be obtained by running
java VerboseHold <Hold file>
This will print a list of the levels in the hold.

Example usage:
$ java VerboseHold "Arena 3.hold"
11285: Arena 1
11286: Arena 3
11287: Arena 2
$ java VerboseHold "Arena 3.hold" 11285 0 1
This will (or at least should) print out Arena 1:1S as text.

Known issues:
- Serpent and rattlesnake bodies will not be shown.
- Tile information (OLAYER and TLAYER) for AE holds will not be shown.
- Scrolls with several paragraphs (with line endings) will not be printed correctly.
- All tile and monster information is numeric, so you'll either have to guess what the numbers stand for, or check the DROD source.
- For some levels (where the level entrance is not in the "standard location" (X=50=Y)) the room coordinates are shifted.
- Most error messages are completely useless.

I think you ought to pull your hacked version. There must have been a reason Stefan disabled it for non-user made holds. My guess is that the official holds are proprietary...

Well, perhaps I'm being overly cautious and protective of Caravel products, but I feel that official holds should receive some special treatment (Official holds have "Only You" editing privileges, so it's clear that Caravel doesn't want people poking around). Maybe it's not that important for this utility in particular, but if I release my utility that extracts data files from holds, I'd definitely put in a check that prevents extraction from official holds (such a utility could, for instance, lower the sales for "Deadly Music of Death").

Oh, and technically, you're not allowed to post that patch here (licensing!). I'm not going to force you to take it down, though, and if no-one from the dev team has any objections, I'll remove the check from the program.

I think that text data isn't secret, because you can extract most of it manually. That's why I hacked the program and posted the patch.
BTW, my friend have a program which can extract all data from imported holds or change owner bits but it isn't user-friendly.
And have I already mentioned at this forum that DROD as a whole needs more copyright protection?

Well... it *is* copyright protected. That's partly why posting binary mods isn't allowed.

If you know how to do it, yes, you can do nearly anything. However, that doesn't mean that you should make it easy for others to do the same.
