I hope this is a simple question but I'm trying to learn how to use Javascript in cMUD.

I'm making a very simple alias to begin the learning.

The alias is called "jscripttest"
and the code is:

var whichrow = 1;
alert(whichrow);

The language is set to jscript, but when I type "jscripttest" it gives the error:

Error Parsing Command:
Object expected [Microsoft JScript runtime error]
(source not available for runtime errors)

My question is, how exactly do you get a cMUD trigger or alias to use Javascript instead of zscript.
I've been learning ZScript and it generally does what I want it to do but I also want to be able to use javascript for things zscript can't achieve.

Are there any instruction manuals or anything like that to help me through?
The internal help for #SCRIPT i cant get working
Syntax: #SCR script language

when i put "#SCRIPT {alert("Hi!");} "JavaScript" it just gives a VBScript error. I've tried many different ways to use that command and it always fails.

I then thought "oh just change the language to JScript" but then I don't know how to output to the CMUD window or anything.

Just need a basic "here's how you do basic things" manual and i'd be able to figure out the rest i'd hope.

Thanks for any assistance.

I have never tried myself.
But you can always double check the the language choice saved properly.
I cant help you with the jscript syntax itself, but perhaps someone could verify that it is done properly.

What exactly is it that you feel can't be accomplished with zscript?

Right now the only thing that ZScript is lacking that I have needed recently is a "Does not match" abililty. the =~ does "match" but what about if "not match". am I just missing something?

For Example, I pull data from a SQL field that contains different flags that an item has.

If the Item has "INIVISIBLE" and "DETECT_INVISIBLE" both and you want it to show "INVIS" and "DI" when doing a list at a merchant, I had to do this: (full code below)

#IF (@ichk.Item("eff") =~ "INVISIBLE") {
#IF (@ichk.Item("eff") =~ "DETECT") {} {p2 = "INVIS "+@p2}
}
#IF (@ichk.Item("eff") =~ "DETECT_INVISIBLE") {p2 = "DI "+@p2}

The other issue I'm having is, the more complex ZScript code I'm writing seems to lag my CMUD (in windows 10, I never noticed this in Windows 7)
Like when the mud is going fast and lots of data is coming through the cursor goes back and forth between "waiting" and regular cursor and it just lags me.

This script also lags and I think it would run faster with Javascript (maybe it would not but I want to learn how to do it with Javascript to find out)

Plus, I know Javascript real well and when I switched from JMC to cMUD I had to rewrite a lot of my scripts and some I just didn't convert over because I didn't know how to do the Zscript version and I would like to get some of those scripts running again.

Do you think that ZScript can do everything JavaScript can do? If so, then I just need to learn it better.

Thanks!!!!

I also thought of another thing I would use JScript for, creating functions (called methods sometimes, subroutines, etc)

Let's say I type group and it shows all 8 people. I want to set buttons with the info in each button, but the class is different and sometimes in different positions in the party (i.e. Position 1 = warrior, but the next group it might be a mage) so rather than have each position check for each class, I could write a function that is called for each position that sends the class name and the health, then the function processes that information.

just would make for neater code.

can Zscript do methods or functions or subroutines?

I'm still wanting to know how to do Javascript though.
I appreciate all the ZScript options that replace things I'd be using Javascript for but it IS something cMUD is supposed to do (use javascript) and I'd like to know how.

Actually, my original post was regarding #SCRIPT.

I can't figure out the syntax to get it to use Javascript. That's what this whole thread was conceived for :)

%mss is also something i've looked at and yes, it will also benefit me but I wanted to get #SCRIPT working first.

%mss also always seems to use VBScript and I can't get it to use Javascript.

and thank you for your reply, I didn't realize you had to make it say "javascriptfunction=" although i'll test the "alert();" function here as soon as I can and see if it works or not.

If cMUD can't do full blown javascript, that's ok, i just need to know that so I quit thinking about it.

Plus, is there a way to pass variables between Zscript and Javascript? or is it your triggers have to be one or the other?

I'm assuming that #SCRIPT will do that but then how do you pass the Zscript variables through #SCRIPT to the Javascript and then back.

I mean, if you could just write a quick alias that does this:

Zscript:
#VAR abc = "123"
#SCRIPT {some javascript, returnin the #VAR abc defined earlier}
#SHOW javascript variable that has the "123" value from #VAR abc earlier.

I'd be able to try to figure out the rest.

The documentation is just so minimal its hard for me to figure anything out.

Everything is assuming you want to use VBscript and it jsut says "and also does javascript" but doesn't show you how to use that!

Thank you so much!!

Wow guys, you are very appreciated.

I'm getting it to work now. However, the "alert()" function of Javascript still does not appear to work.

I copy/pasted your example and sure enough, it outputs 6 to the screen.

However, if I add "alert(x);" before the "return x+1;" it gives an error and doesn't work. That is what I meant by "full blown" javascript. I don't need the alert() function to work, its just how I was testing things. But, presuming i'm not doing something wrong, it would seem that alert() doesn't work with zscript or %mss or something. Not a big deal but if one function doesn't work, others might not as well, leading to me saying "not full blown javascript"

I'm going to play around with some things and learn to use the "zvar" as well.

Are there any help files relating to the "zvar" and other features that might exist? When I search "zvar" in the CMUD Help files It returns nothing, so how does one go about learning about this and the other features related to scripting with other languages other than zscript in cmud? Maybe I'm supposed to have Pro version before i'm able to get help with that stuff?

Any links to information relating to those features and others would be greatly appreciated.

Thank you so much! I'm sure i'll have more questions but for now I think you've taken care of me pretty well!

Oh!! I cant believe I didn't think about the ! (not) operator. I use that all day in PHP so I have no excuse why I didn't think of that. Also, I didn't know about the %q word boundary. That is very helpful also. Can you by chance tell me where that is found in the Help files also? I bet there are more % commands I can use that I don't know about.

Thank you again!!!

in #HELP #TRIGGER there is a link to the pattern matching wildcards.
you can also search for 'predefined' to get a list of native %variables
