Mudlet Coding Questions

Radakail

Didn't see a thread for general questions about coding in Mudlet specifically, so here you go! I'll start.

I'm trying to make a script to track certain information via GMCP. The code looks like this:

function CharVitals(event,args)
cecho("stage1")
vitals = gmcp.Char.Vitals
cecho("stage2")
if vitals.herb == 1 then
balance.herbs = true
else
balance.herbs = false
end
cecho("stage3")

end

I'm using a registered event handler of 'gmcp.Char.Vitals'. This worked for me in Achaea using Mudlet, and I've checked to make sure gmcp.Char.Vitals.herb is a valid references in Aetolia. I put in error checks in the form of echoes, but the script doesn't function at all. Not even at 'stage 1'. This is also the exact error I get in the Lua console:

[ERROR:] object: (event handler function) function:(Status)(attempt to call a nil value)

*replaced HTML tags in the error.


Can anyone help?

Just got the echoes working, but for some reason balance.herbs remains false... despite gmcp.Char.Vitals.herb being 1.

Oh lol, looks like the 1 in gmcp is a string. Awkward.

If anyone else has this problem, replace the gmcp.Char.Vitals.thing == 1 with gmcp.Char.Vitals.thing == "1".

Did you initialise the 'balance' table?

Just as a note, a really easy way to capture stuff like this is something like this:

function get_stats()
if not gmcp.Char or not gmcp.Char.Status then
return e.echo("Awaiting a GMCP status packet.")
end

local stats = {
"unread_msgs",
"guild",
"explorer",
"class",
"unread_news",
"bank",
"order",
"race",
"name",
"gold",
"status",
"level",
"city",
"fullname"
}

-- This block just captures any changes in value and runs the ui:update_status_bar() function if a change is detected.
for _, key in ipairs(stats) do
if o.stats.last[key] ~= o.stats[key] then
ui:update_status_bar()
end

o.stats.last[key] = o.stats[key]
end

-- This literally just iterates over the stats table and downloads each key.
for _, key in ipairs(stats) do
o.stats[key] = gmcp.Char.Status[key]
end

-- This is just a quick, lazy add-on I did to make sure 'class' and 'status' are always lower case, and 'vampire' just returns 'undead.'
o.stats.class = o.stats.class:lower()
o.stats.status = o.stats.status:lower():gsub("vampire", "undead")
end

This basic system has GMCP handling through events @Radakail‌, I could explain it but this will let you look at the code for it

to see where you went wrong / right ..

I used event handlers in the script to begin with. The problem was GMCP in Aetolia utilising strings for their Boolean states of 1/0. I commented after my initial post on how to deal with that. Took a while of angry error checking to figure it out.

take a look at the above script on how he did it.

but you have to name the script ' CharVitals '

and its

function CharVitals( event ) not, CharVitals(event,args)

and this, vitals = gmcp.Char.Vitals

really unsure what you trying to do here.. but cant do that in mudlet only in cmud if im correct on what your trying.

Like i said, that link has a small starter script in mudlet and has it all in, take a look at it @Radakail‌ it might make more sense then us describing it on here

Someone asked me if there was a way to look at the code in a function without having to pull up the editor. Figured I'd share it. debug.getinfo(foo).source
