So, you'd like to start programming in Lua. Your holy bible should be:
- Lua book (http://www.lua.org/pil/)
- 5.1 reference manual (http://www.lua.org/manual/5.1/)
- PtokaX Wiki (http://wiki.ptokax.ath.cx/doku.php)

And also we encourage lua-related discussion here, it's kinda boring to code 'can I have this in PM' issues all the time.

thanks you all the member for your support. the site and the reference manual suggested by the scripter and members are very helpful but the prob is tht they are to big and vast (boaring also) to read with my speed i will require atleast 2 months to read tht whole thing i cant manage tht much time. so can u suggest me any other way through which i can learn the language in small,simple and easy way


thanks in advance

I started with creating a simple bot. You should create one too:

I started with creating a simple bot. You should create one too:
  • register at startup
  • when a new user connects, greet her
  • when a user disconnects, say goodbye

Done :D

  • when a user disconnects, say goodbye

here is my try
Code: [Select]
sBot ="Fusion"
mesg ="this hub welcomes all regs. Hope u enjoy ur stay"
mesg1 ="Good bye!! c u soon"
function NewUserConnected(user)
user:SendData(sBot, mesg)
end
OpConnected = NewUserConnected

function UserDisconnected(user)
SendToAll(sBot, mesg1)
end
OpDisconnected = UserDisconnected

how is it, i will like to here all suggestions but plzz be abit explainatory ;)
how do u register a bot?

i even tried to do this profile specific
Code: [Select]
sBot ="Fusion"
mesg ="this hub welcomes all regs. Hope u enjoy ur stay"
mesg1 ="Good bye!! c u soon"
mesg2 ="welcome home"
function NewUserConnected(user)
if user.iProfile ==0 or user.iProfile ==1 then
user:SendData(sBot, mesg2)
else
user:SendData(sBot, mesg)
end
end

function UserDisconnected(user)
SendToAll(sBot, mesg1)
end
OpDisconnected = UserDisconnected

it doesnt work :( what is the change needed.

thks,

If you check whether a user is registered, bRegistered would be a better choice. Registering a bot: hmm, documented.

Code: [Select]
function NewUserConnected(user)

Hint (SPOILER WARNING!!!)  :)
This'll never be true in itself, you need to do is similarly to disconnection

Code: [Select]
OpDisconnected = UserDisconnected

This code is actually quite close. It doesn't work because the bot isn't registered, and most clients ignore messages from offline users.

To register your bot:

Code: [Select]
Main = function()
      frmHub:RegBot(sBot)
end

that should do it :)

I think they don't benefit from directly telling them the solution, we should rather give them hnts.

For speedX example:

end

This version is most good :p

If only the second version is the one that's not working (as I've suspected), then see my post. The second version misses a line...
Title: Re: Scripting Help
Post by: 6Marilyn6Manson6 on 03 May, 2007, 23:38:51
There is no functional difference here.

Sure? but speedX has been only used  mode  funtion name()   only for this my version would be more homogenous ^^
Title: Re: Scripting Help
Post by: speedX on 04 May, 2007, 10:43:20
Code: [Select]
Bot = frmHub:GetHubBotName()


function Main()
frmHub:RegBot(Bot)
end

function NewUserConnected(user)
  if user.bOperator then
    user:SendData(Bot, "Welcome home "..user.sName)
  else
    user:SendData(Bot, "Welcome "..user.sName.." to "..frmHub:GetHubName())

end
OpConnected = NewUserConnected

function UserDisconnected(user)
  SendToAll(Bot, "Goodbye "..user.sName)

well i m trying to add some more messages and it should send random message
Title: Re: Scripting Help
Post by: Naithif on 05 May, 2007, 01:16:03

i even tried to do this profile specific
Code: [Select]
sBot ="Fusion"
mesg ="this hub welcomes all regs. Hope u enjoy ur stay"
mesg1 ="Good bye!! c u soon"
mesg2 ="welcome home"
function NewUserConnected(user)
if user.iProfile ==0 or user.iProfile ==1 then
user:SendData(sBot, mesg2)
else
user:SendData(sBot, mesg)
end
end

function UserDisconnected(user)
SendToAll(sBot, mesg1)
end
OpDisconnected = UserDisconnected

Here's your post.
You got a NewUserConnected function that's targets are users. (user, reg, vip)
You got a profile check that's targets are masters, and ops

Hint 1
NewUserConnected takes all users, regs, and vips, and the if statement filters everyone of them except ops and masters.  ::)


Hint 2
You are missing a line that was present in version 1...

Title: Re: Scripting Help
Post by: achiever on 05 May, 2007, 10:21:35
well yes got it
i had missed OpConnected = NewUserConnected

This is not exactly true.
NewUserConnected handles all users with a profile with bIsOP = 0 , and unregistered users.
Subtle, yet important difference if you use custom profile permissions  ::)

By default, me refers to default profile setting (;D)
Anyway, in 99% this is the case, also if robocop, or leviathan profiles are in use

@ B?stya -> Hints are just not working

(And next time if someone got a problem, then paste the script you got the error with, as line 15 is 'end,' no '{'-s there

zztime bot.lua:19: '}' expected (to close '{' at line 15) near 'end'

Your problem is:

Post by: Psycho_Chihuahua on 18 May, 2007, 13:27:19
as American Idiot has said already LUA is Case Sensitive

so change
Code: [Select]
return tCmds[cmd](User, data)to
Code: [Select]
return tCmds[cmd](user, data)
because User is NOT = user

Code: [Select]
sBot = frmHub:GetHubBotName()

ChatArrival = function(user,data)
local sBot,h,m = "Time",math.modf((os.time()-os.time(os.date"!*t"))/ 3600)
local s,e,cmd = string.find(data,"%b<>%s%p(%w+)")
if cmd then
local tCmds = {
["time"] = function(user,data)
return user:SendData(sBot,os.date("Time: %I:%M:%S %p   Date: %A, %b %d, %Y "))
end,
["date"] = function(user,data)
return user:SendData(sBot,os.date("Date: %A, %b %d, %Y   Time: %I:%M:%S %p "))
end,
}

if tCmds[cmd] then
return tCmds[cmd](user, data)
         end
        end
end
ToArrival = ChatArrival

results in
Code: [Select]
[13:15:16] <Psycho_Chihuahua> time
[13:15:19] <Time> Time: 01:15:19 PM   Date: Friday, May 18, 2007

Could someone plzz explain me this.
Code: [Select]
local sBot,h,m = "Time",math.modf((os.time()-os.time(os.date"!*t"))/ 3600)
local s,e,cmd = string.find(data,"%b<>%s%p(%w+)")

Post by: achiever on 19 May, 2007, 09:23:19
Code: [Select]
local sBot,h,m = "Time",math.modf((os.time()-os.time(os.date"!*t"))/ 3600)
local s,e,cmd = string.find(data,"%b<>%s%p(%w+)")
the second line is the capture pattern of strings

math.modf function is used, i think for geting the fraction and integer differently (its acually used to spilt the 2 parts if m not wrong)

os.date() this fuction returns the date and time

this all i can guess but,
Code: [Select]
local sBot,h,m = "Time",math.modf(([b]os.time()-os.time(os.date"!*t"[/b]))/ 3600)
what this ((os.time()-os.time(os.date"!*t"))/ 3600) is even i would like to understand
