A bug with object speech scripts using * as arg

Building & Scripting > Scripting Board

Molly:
Here is a weird bug, and I am not sure whether it is caused by context on the mob speech script, or the object speech scripts using * as arg. In any case the two scripts interfere with one another.

Hayato demonstrated it to me, and he says it's caused by % signs, but I don't really understand how that could be.

Anyhow, here is what happens:
We know of the bug affecting two items so far. (There might be others, but probably not many, since most objects with speech scripts set on them are !take).
The ones we know of are:
44591 the flying carpet from Aegean Island (script vnum 44531)
25645 a glowing silver-topped cane from Victorian England (script vnum 25620)

Both those objects react to speech scripts from whoever has them. Both the speech scripts have * as arg.
Both objects are also pretty good, so anyone who managed to acquire them is also likely to carry them around at most times.

But the speech scripts on the objects also interact with speech scripts on quest mobs in an undesirable way, meaning that the mobs won't respond to key phrases, unless you put the objects in question in a bag. Then the questmob suddenly acts normal again.

It's a very irritating bug that isn't very obvious, so a player could go around for ages, missing out on quest because of it.
It doesn't happen to all mobs with a speech script however, for instance the Time Guardian (3169, with the script 3366) still works fine. But as an example, Director Leatherwell (8225, with script 62212) doesn't. (There are probably several more examples, but for these you need to ask Hayato).

The time Guardian has a script that reacts to various keywords, with * as arg.
Leatherwell has a simpler script, reacting to one of the common greeting phrases, but it also uses context.

I've experimented by putting either return 0 or return 1 as elseif checks on the object script, but neither seems to work.
However Leatherwell works fine if Hayato puts the two objects in a bag.

At present I am stumped myself, and I don't really have the spare time toexperiment either. Hopefully one of our script gurus can figure out what's wrong and how we should set up the scripts in the future to prevent similar things from happening..

The scripts are below:

Mordecai:
this has always been the case, it happens with command scripts too.

There isn't a way to change the code to get around it, that is how the trigger system works.

Obviously the way to change it is to change the arg to not be an *, but instead be the list of words you expect the person to say.

To find all of the triggers affected this way do a tsearch:

--- Code: ---tsearch arg *
--- End code ---

Molly:
Heh, it seems the scripts, as they stand, work fine even with the * in the arg list.

The whole issue was caused by two mistakes, me not putting a return 0 as elseif, and Hayato typoing with the greet phrase.

But at least I learned something from it; having all the arguments you want the object to react to in the arg list instead of the *, is a much safer way to set up scripts like this.
