another question .....how can i pick up an random element from a table which uses strings as index/key?

like:
a["aa"]="ddd"
a["vadsv"]="vjicv"
a["02a"]="..."

how can i randomly pick a key/value from a[]?

put the keys in a numeric table, say "kees[]" and choose a random number n from 1 to #kees. kees[n] is your random key.

Edit:
Or just choose a random number m from 1 to #a, then loop over "k,v in pairs(a)" and stop at the m-th iteration.

sorry, is it possible to use "#a" as the length? i can't use it when the keys are all string.

lua code:

Oops, yeah, forgot that. See box' answer.

I'd recommend my first approach then since it loops over the array only once. You could also store the entry count as an extra field in the table.

why does this work


but this doesnt?

string.find() takes a regular expression (also called pattern in lua) as argument. "[" and "]" are special characters in a regular expression. For example 'string.find(yourString, "[aeiou]")' will find the first vocal in your string. You can read more about this in the lua-users wiki.

I think 'find.(a, "]")' works because it is not a valid regular expression because of the unmatching bracket so lua just assumes you are searching for the string instead.

The solution to your problem is to put a "%" infront of the bracket: 'find.(a, "%[")'
The "%" means "if a special character follows, don't treat it as a special character but use it literal instead".

Also a quick tip: You can write 'a:find("%[")' instead of 'string.find(a, "%[")'. Note the colon though, it's necessary. Works only for variables so '"asdf":find(...)' won't work.

Sorry guys, I forgot from the last time I was here.

Is there documentation for all of the toribash lua functions? I'm going to be really surprised if there isn't documentation that has every command. I can't find anything though.


Failing that, what's the command to detect/see who sent TC to the player running the script?

And is there a way to send TC with a script?


I'm thinking I probably have to use that addon that lets you use http functions, and have it login and do it that way?

There isn't. In your data/script/ directory there's a folder called "sdk" that explains some of them but not all. You can get every function name by searching through a table called "_G". It contains every global variable, including functions. You won't get any documentation though and some of the functions don't seem to do anything.



You can't do that. May work with an extention but I don't know/use any. Use at your own risk.

Is there any more effective way to get someones name from a line in chat than this?

local function getName(chat)

if string.find(chat, ")", 0) ~= nil then 
usr = string.sub(chat, string.find(chat, ")", 0), string.find(chat, ">")-4)
lineStart = string.find(chat, ")", 0)
lineEnd = string.find(chat, ">")-4
elseif string.find(chat, "]", 0) ~= nil then 
usr = string.sub(chat, string.find(chat, "]", 0), string.find(chat, ">")-4)
lineStart = string.find(chat, "]", 0)
lineEnd = string.find(chat, ">")-4

else usr = string.sub(chat, string.find(chat, "<", 0) + 4, string.find(chat, ">")-4)
lineStart = string.find(chat, "<", 0)+4
lineEnd = string.find(chat, ">")-4

end
return usr, lineStart, lineEnd

end

add_hook("console","console",getName)
