Zugg Software :: View topic - [Resolved] [3.33a] Simple trigger to add wording to the end of a MUD's output -

Novice Joined: 15 Jul 2010 Posts: 39 Location: USA

Let's say I see:

<room description here>

a bobbing bobcat (0.681)
a dagger

<exits line>

and I want to add something to the end of the a bobbing bobcat (0.681) so that it looks like this:

a bobbing bobcat (0.681) (This mob has a tendancy to flee)
or
a bobbing bobcat (0.681) *runner*
or
a bobbing bobcat (0.681) Runs
or something simple like that.

Is there a way to do a trigger like:

Trigger pattern: a bobbing bobcat
Trigger: #SAY This mob runs

but have the output on the same line, rather than using a #SAY on a seperate line?

#SUB the original line with your appended text.

Don't need #SUB, just use #SAYADD if it goes at the end of the line

Much better way is to use the #SAYADD command.

Then you could do:

Thanks. That helps a lot. Is there a way to change the color of the added text used by #SAYADD?

Got it

#SAYADD %ansi(cyan)" *Runs*"

Let me know if there is a more appropriate method or if this is good.

#SAYADD {%concat( %ansi(cyan), " *Runs*")}

would be the most appropriate way to format it.

You don't even need the %concat... #SAYADD {%ansi(cyan) *Runs*} works just as well. Remember, things in {} are counted as strings except for functions.

I thought Zugg recommended against implicit concatenation?

What is "concatenation", and what is it that the %concat function is doing?

Concatenation is essentially adding strings together. Yes, that is what the %concat() function does. When you put "A", "B", and "C" together to make "ABC", that is concatenation. Implicit concatenation is simply putting the pieces of string next to each other and hoping that Cmud interprets it correctly and builds them into the longer string you want. Explicit concatenation means using a function or command specifically designed to concatenate. %concat() is the concatenation function for Cmud. Implicit concatenation works much of the time in Cmud, but in some situations it doesn't work, and occasionally it works in a specific situation in one version, but not in a later upgrade. In general, explicit concatenation is safer, and guaranteed to work (guaranteed in the sense that, if it doesn't, it is a bug and will get fixed). Implicit concatenation should work in all of the printing commands like #SHOW, #PRINT, #ECHO, #SAYADD, etc., especially if enclosed in curly braces as Charneus suggested. I suspect most people would consider it a bug if it stopped working for those commands, and Zugg would probably agree. But Chamenas is correct that the strictest coding would use %concat().

In the matter of small scripts it is likely less important, since, if something breaks it's often easy to isolate. I often write larger scripts and scripts for other people, in which case I want to make the scripts as version proof as I can. If it works it works, but it doesn't hurt to begin such considerations so that if you ever "graduate" into something more complex you will be able to keep the code manageable.

Thank you for the help. I definately plan on 'graduating' as i go along, I just don't exactly know where to start. all I do right now are simple triggers, coloring outputs, setting variables and doing basic %IF functions to make things happen.

I want to get into the database variables and such, but I don't really know where to begin...

Well, don't force it. The simple stuff is a good way to learn, eventually you'll run into problems where the only solutions require slightly more elegant ways of thinking about things. You'll get there. And, of course, simply reading about them in the helpfiles is always a good place to begin. Smile

Wow, I just learned something new. Despite the complexity of my scripts, I've never run across 'sayadd' before.
