Is it possible to trigger an image to replace the words being said? For example -

When someone says Kappa, I want to replace the word with the Kappa emoji image. Right now, I've got a simple snippet up:

Not that I am aware of.

I believe you can inline the image using #SUBSTITUTE and MXP. See https://www.zuggsoft.com/zmud/mxp.htm

Well, we've made some progress atleast to the inline function:

Script is as follows:

#SUB replaces the entire matched pattern, and * is very greedy

#TR {(%w) kappa (%w)} {#SUB {image}}

would only match single words on either side.
but i would use:
#TR {kappa} {#SUB {image}}

you need to enable the repeat within line option for it to fire more than once in the same line.

Hey shalimar,

I went with your second suggestion with the repeat within line option enabled.

It works perfectly with one mention. When you have more, however, it starts behaving oddly. See below.

Any ideas? Or is this just a MXP/IMAGE limitation?

Thanks.

I think it has to do with the fact that images have no set character width, so its having issue with the spacing.
Not sure what can be done about it.
Maybe instead of #SUBing the images in you could use #SAYADD to append the image to the end of the line?
No need for it to repeat within line then, which seems to be the issue with images.

Try doing the repeat in code instead with only 1 substitution.

#REGEX {\bkappa\b} {#PSUB {%subregex(%line, "\bkappa\b", "<IMAGE ...>")}}

I'll admit that I am out of my element with REGEX and such.

Using your code and changing only the ... in the image tag to add the filepath, it appeared to only echo the image information a few times as well as the mud-based prompt.

The use of regex in this case is to catch word boundaries so that it will only match when the text you want to replace appears to be a distinct word. The trigger I provided should not have the Repeat with Lines flag set. But it also looks to be having some other problems. It looks like #PSUB did not activate the MXP and all the ANSI color information was lost.

Scrap the old and now we get a little more complex...

Hey Vijilante - Thanks so much for helping with all of this!

So, That worked perfectly, no matter what I did with it!

However, when I tried to add a second emoji (just copied the code and changed kappa to pride)... well, it works fine if you do it on its own line. But if you try to have two emojis on the same line in any way, it actually crashed cMud. But gave me this error:

Looks like the trigger in question had a pattern of *1.
That looks more like an #ALARM.

I am not really sure why it caused a trigger loop, but let's reduce it to 1 trigger and eliminate that problem. Because %subregex uses backslashes to reference captured data and we not have some I felt it prudent to cover all backslashes with proper escaping.

I was sort of expecting you would want many emoji. If you are putting all the emoji pictures in one place then a simple list would do for the solution; otherwise you will want to use a record variable and there will be a few other changes. I added the "no trigger" option which turns off "trigger on trigger" which should prevent any sort of trigger loop.
