| Hi Nick and all,
As a newbie to mushclient, I am trying to follow Nick's reply in this post to build up my own tracker for a MUD I'm playing:
https://mushclient.com/forum/?id=8843&reply=4#reply4
Here is my code:
date = os.date ("%d-%m-%Y") -- eg. 06-08-2008
xp_gained [date] = (xp_gained [date] or 0) + xp
xp = %2 -- the xp gained
%2 is set by the trigger as below(sorry the description is in Traditional Chinese since I'm playing a MUD built up and run in Taiwan):
^吒]為你殺死了(.*),得到了\s+(\d+)點經驗值和\s+(\d+)點潛能以及\s+(\d+)點聲望。$
The trigger is successfully triggered, while I encountered this error message and could not resolve it after trail and errors for several days:
Run-time error
World: 再戰江湖
Immediate execution
[string "Trigger: "]:3: attempt to index global 'xp_gained' (a nil value)
stack traceback:
[string "Trigger: "]:3: in main chunk
Could Nick or anyone shed some light on this? Ideally, I want to track 3 stats (XP, POT, and SC) after killing mobs in the given period (hours or days) and show in a table.
Thanks for help in advance. | Top |

The error simply states that "xp_gained" is nil. You'll need to make sure that "xp_gained" is previously defined as a table prior to trying to pull information from it. If you create a new table daily, then the easiest way will be:
If you tend to save the table over time, you'll want to save it as a variable and load it each time you restart. See https://mushclient.com/forum/?id=6030&reply=11#reply11
Hopefully this helps break it down for you. | Top |

| If you are doing that in a trigger you don't want to make the table every time. Try:
if not xp_gained then
xp_gained = {} -- make table if it doesn't exist
end

Thanks for the explanation and the tips to fix it.

It works now - thanks for the sharing.
However, when I further tried to replicate in the same trigger with the similar codes for other 2 stats captured by %3 and %4, I bumped into another error message:
Run-time error
World: 再戰江湖
Immediate execution
[string "Trigger: "]:12: attempt to perform arithmetic on global 'sc' (a nil value)
stack traceback:
[string "Trigger: "]:12: in main chunk
My code is like below:
date = os.date ("%d-%m-%Y")
if not xp_gained then
xp_gained = {} -- make table if it doesn't exist
end
if not pot_gained then
pot_gained = {} -- make table if it doesn't exist
end
if not sc_gained then
sc_gained = {} -- make table if it doesn't exist
end
xp_gained [date] = (xp_gained [date] or 0) + xp
pot_gained [date] = (pot_gained [date] or 0) + pot
sc_gained [date] = (sc_gained [date] or 0) + sc
xp = %2 -- the xp gained
pot = %3 -- the pot gained
sc = %4 -- the sc gained
May I have your guidance about what went wrong? Thanks. | Top |

-- Here you do arithmetic on sc:
sc_gained [date] = (sc_gained [date] or 0) + sc
xp = %2 -- the xp gained
pot = %3 -- the pot gained
-- Here you establish a value for sc:
sc = %4 -- the sc gained
In other words, you need to establish the value of sc before adding it to something. |

Thanks Nick for the guidance. I set sc = %4 before sc_gained [date] then it can work :)
I further revised the code to track 3 stats in the mud I am playing - share as below:
Quote: trigger: ^吒]為你殺死了(.*),得到了\s+(\d+)點經驗值和\s+(\d+)點潛能以及\s+(\d+)點聲望。$
Once the trigger is matched, send
date = os.date ("%d-%m-%Y")
xp = %2 -- the xp gained
pot = %3 -- the pot gained
sc = %4 -- the sc gained
if not stats then
stats = {}
end
if not stats[date] then
stats[date] = {} -- make table if it doesn't exist
end
stats[date].xp_gained = (stats[date].xp_gained or 0) + xp
stats[date].pot_gained = (stats[date].pot_gained or 0) + pot
stats[date].sc_gained = (stats[date].sc_gained or 0) + sc
Add in script file the function Nick mentioned in the following post to establish a recursive table printer:
https://www.gammon.com.au/forum/?id=4903
function tprint (t, indent, done)
done = done or {}
indent = indent or 0
for key, value in pairs (t) do
Tell (string.rep (" ", indent)) -- indent it
if type (value) == "table" and not done [value] then
done [value] = true
Note (tostring (key), ":");
tprint (value, indent + 2, done)
else
Tell (tostring (key), "=")
print (value)
end
end
end
Then set 2 variables for saving / loading accumulated stats:
save_stats
require "serialize"
SetVariable ("stats", serialize.save ("stats"))
Note ("Accumulated stats have been saved.")
load_stats
loadstring (GetVariable ("stats")) ()
tprint (stats)
Note ("Accumulated stats have been loaded.")
The codes are not ideal but just want to do an experience sharing for those who are troubled by similar topic.
Also welcome Nick and other experts' comments for improvement. Thanks. | Top |
