Have you actually TRIED to find some scripting help on the forum? I'm sure there are plenty of topics regarding scripting in Architecture. And BTW, DROD scripting is pretty straight-forward, in my opinion.

The manual seems pretty detailed at describing what the various commands do. It's bound to be more useful than a tutorial, as that would probably only be useful for a small number of situations.

Besides, it will probably be hard to show you how to add a command to a script.

There could be a room with a lot of long scrolls packed with scripting information, and then a room with the results of the scripts?

Okay. I could do that...
However, to learn how to really script you need to understand program flow, and other basic programming skills, which I am not good enough to teach. You can learn visual basic (in Microsoft Word/Excel), which is a simple language that will get you that sort of skills. Or you could go for something like C++, which there are tutorials on the web for, like this one. The only thing that a tutorial will do is teach you how to use the commands. I can start on it, but I'm not going to guarantee anything unless people say that something like this would be useful.

In that case I think it's probably not worth doing it (unless you want to do it as an writing exercise). I don't think anyone here wants another commands overview list; the manual does that job pretty well already.

If you really want to write a tutorial then I'd suggest you cover all the rest of the stuff as well.

But if you really want to please 13th Slayer, then it's important to write correctly, as he's only interested in that, as you can see in this thread.

Drod scripting isnt mucha straightforfard now... With all the IF's, VAR's, ELSE's, END's (which's action is messed up with Go to level entrance).

Actually, it is the most straight-forward language I know.

Are the parts that require a bunch of repetition where variables are involved the thorns?

I find DRoD to be incredibly easy to script in because they use words and English sentences to replace confusing code. Also, the code behind the code is bug-free, so you don't have to worry about fixing code from a place that you can't fix code.

The thing about scripts is that they do exactly what they say, so it's really hard to provide more explanation.

Nope. The folder was red and it was on the first page.

Someone probably posted, thus bumping it, then deleted the post. The folder remains red. The end.

Alrighty...:

If, Else, End If: Uses the next statement as a condition, if possible. Most "Wait" statements can be used as conditions, with ignoring the statement=TRUE and waiting for one or more turns=FALSE. So can Question if there are no Answer Options, with Yes=TRUE and No=FALSE. Wait Until Var is highly useful, for what I should hope are obvious reasons. Then is implied, else is not. To close an If block, use End if. There is no command to break out of an if block, aside from GOTO.

Example (Note that this is hand-typed and cannot be pasted easily into DROD):
Wait 5
If..
Wait for player at 4,4
Speech "Muehehe"
Else
Speech "Onos!"
End if

This will wait five turns, then make a comment based on whether the player is at 4,4 or elsewhere.

Label, Goto: Sadly, GOTO is highly necessary in DROD script because there is no concept of a function. Also, all jump targets are hardcoded. You must make the target label first, then it will appear in Goto's list and can be selected. Then, when the script encounters the Goto, it jumps to the specified label.

Question, Answer Option: Question can do two different things: Either it can present a menu of options associated with labels, and selecting one jumps to that point, or it can ask a yes or no question. The second form can be used as a conditional in if statements, or as a no-op that displays a dialog box outside of them. (That is, neither answer does anything if there are no answer options and it is not being used as a condition to an If statement.) To use the first form, you must first specify a list of Answer Options, one at a time. Each answer option consists of a bit of text and a label. If answer options have been set, Question will display them as a menu, and then go to the label of the one the player selects. Afterwards it will clear the set answer options and any further question will be a Yes/No question unless they are set again.

Wait 0: Wait 0 is mostly used in keeping a script running despite infinite loops. If a script runs for too long, it is presumed to be an infinite loop and ended. If you want to check for several conditions each turn, (or probably other uses, though this is the main one), then you need a loop over If statements, with a wait 0 at the end or beginning to make it wait a turn instead of being ended. There is a difference between wait 0 and wait 1, though I can't remember it at the moment.

Everything else should do exactly what it says on the tin, IIRC... although the built-in variables in DROD RPG are tricksy...

That clear enough?

Now, what is the difference between "End" and "End on room exit" if there are no further instructions in the script?

There is no noticeable difference. Characters do not disappear or die when you use End. The difference between them is the fact that End stops the script right there, and End on room exit lets the script continue, but ends it when you leave.

Another possible complication is if we wish to test for two conditions being met simultaneously. I would guess you would do this:

Label StartLoop
If...
Wait for player at (4,4)
If...
Wait for player to face NW
Speech Player "Hello, I'm facing northwest today"
If End
If End
Wait 0
Goto StartLoop

Do I have the right idea?

Yes, you have the right idea. Basically, to convert an expression of Boolean Algebra to DROD script:

A OR B:



A AND B:



NOT A:



A XOR B:



And the rest should be trivial. Note that scripts do not automatically end when there are no more commands, they just wait until the player re-enters the room. (Also note that Restart on Room Entrance is off by default in DROD RPG, although a script at the end that is not set to restart may still do something via usage and fighting.)
