Lua Question

Cloow · Jul 9, 2010

Alright, i made a quick script. My first one actually.

Here is my question, if i want the line

if item.itemid == 59281 then

To be UID instead of itemID what should i do?

Also, when im trying to start the server with my script i get this error

and i can't just see what i have done wrong.

PHP:

local t = 
{
      monster = "Monster"
	  pos = {x=967, y=1007, z=7},
	  msg = "Monster appears right infront of your eyes!!"
	  tpos = {x=967, y=1007, z=7},
	  cpod = {x=960, y=1007, z=7},
	  bmsg = "How dare you?!"
}

function onUse(cid, item, fromPosition, itemEx, toPosition)
       if item.itemuid == 59281 then
         doSummonCreature(t.monster,t.pos)
		  doCreatureSay(cid, t.msg, TALKTYPE_ORANGE_1)
		   doCreateTeleport(1387, t.tpos, t.cpos)
		     doBroadcastMessage(t.bmsg, TALKTYPE_RED_1)
		    return TRUE
     end
end

If you see any errors, wich will not work when im testing this. I would love to know em =>

Soon enough im gonna be pro on scripting !

Code:

local t = 
{
      monster = "Monster",
      pos = {x=967, y=1007, z=7},
      msg = "Monster appears right infront of your eyes!!",
      tpos = {x=967, y=1007, z=7},
      cpod = {x=960, y=1007, z=7},
      bmsg = "How dare you?!"
}

function onUse(cid, item, fromPosition, itemEx, toPosition)
       if item.uid == 59281 then
         doSummonCreature(t.monster,t.pos)
          doCreatureSay(cid, t.msg, TALKTYPE_ORANGE_1)
           doCreateTeleport(1387, t.tpos, t.cpos)
             doBroadcastMessage(t.bmsg, TALKTYPE_RED_1)
     end
return TRUE
end

it's item.uid

also, you don't really need it... just register it in actions.xml with "actionuid"

WibbenZ · Jul 9, 2010

UID/AID = ex. quest chest.
while id = is the id of the item ex.

Lua:

 if item.id == 2160 then
  return doCreature......
end

Cloow · Jul 9, 2010

Alright, i've tested the script now. Almost everything works.

But this line just dont want to work

PHP:

      doCreateTeleport(1387, t.tpos, t.cpos)
             doBroadcastMessage(t.bmsg, TALKTYPE_RED_1)

Why that ?

Also i can just pull the switch once.

Code:

local t = 
{
      monster = "Monster"
      pos = {x=967, y=1007, z=7},
      msg = "Monster appears right infront of your eyes!!"
      tpos = {x=967, y=1007, z=7},
      [B]cpod[/B] = {x=960, y=1007, z=7},
      bmsg = "How dare you?!"
}

function onUse(cid, item, fromPosition, itemEx, toPosition)
    if item.uid == 59281 then
        doSummonCreature(t.monster,t.pos)
        doCreatureSay(cid,t.msg,TALKTYPE_ORANGE_1)
        doBroadcastMessage(t.bmsg)
	doCreateTeleport(1387,t.tpos,t.[B]cpod[/B])
    end
    return true
end

in the doCreateTeleport you've given the wrong local, you used cpos instead of cpod.

Also with doBroadcastMessage you don't need to define the color.

Also, I suggest you to use the TAB button instead of using space

Oh, lol!

My mistake.

Alright, thanks for the help guys.

Repped all of u

Cloow · Jul 9, 2010

Hey guys, i got another question.

doPlayerPopupFYI(cid,msg)

This CID what does that mean ? It's here to

function onLogin(cid)

Ahh, another one.

can someone explain to me, why is these important ?

function onUse(cid, item, fromPosition, itemEx, toPosition)

I mean it's not used in scripts anyway.

doPlayerAddMapMark(cid, pos, type[, description])

type ? Wich mean? It's it like effects ?

Here's one to

PHP:

local t = 
{     
      msg = "TEXT"
      pos = {x=693, y=1007, z=7},
	  typ = 
}	   
	   
function onLogin(cid)
  doPlayerPopupFYI(cid, t.msg)
    doPlayerAddMapMark(cid, t.pos, t.typ)
	end
	return TRUE
end

I can't just see where it is to close ?

Ecstacy · Jul 9, 2010

The CID means creature ID, also know as the person for which the action is executed.

So in your cases the cid is for a player who activates a script.

--

function onUse(cid, item, fromPosition, itemEx, toPosition)

You can leave it out, but I suggest you not to as you might reconsider to change something in the script that DOES use it.

--

doPlayerAddMapMark(cid, pos, type[, description])

I'm not sure about this one, but I'm guessing that it's the type of icon.

So the CID is kinda important ? So in my case

PHP:

doPlayerPopupFYI(cid, t.msg)

I got to type the CID of the starter outfit there ?

NOTE: I updated the post @up

Code:

local t = 
{     
      msg = "TEXT"[B][COLOR="Red"],[/COLOR][/B]
      pos = {x=693, y=1007, z=7},
      typ = 0 -- I guess :|
}       
       
function onLogin(cid)
  doPlayerPopupFYI(cid, t.msg)
    doPlayerAddMapMark(cid, t.pos, t.typ)
    end
    return TRUE
end

zieworski denero · Jul 9, 2010

cid means Creature ID, which means the player himself - so if you put "cid" in a script, the script executes on the player... dunno how to explain really but i guess unknown666, the troll xD, explained it well

yes, cid is important.

Code:

local t = 
{     
      msg = "TEXT"
      pos = {x=693, y=1007, z=7},
      typ = 
}       
       
function onLogin(cid)
  doPlayerPopupFYI(cid, t.msg)
    doPlayerAddMapMark(cid, t.pos, t.typ)
    end
    return TRUE
end

you don't need to make a .lua file, just paste

Code:

  doPlayerPopupFYI(cid, "TEXT")
    doPlayerAddMapMark(cid, {x=693, y=1007, z=7}, "blabla")

in your login.lua, so everytime a player logs in this happens.

edit: too late, troll posted b4 me -.-

edit2: typ should probably be '""' so like this:

typ = ""

Cloow · Jul 9, 2010

Ahh, thanks!

This is wierd.
Now i get this error -

'<eof>' expected near 'end'

edit: But if i add it on login.lua in appears everytime someone logs. I want it just to heppend when they first login, with a new char

Ecstacy · Jul 9, 2010

My bad, didn't see that.

The error is because of the double 'end'.
there is no condition (if) so you don't need more than 1 end.

Code:

local t = 
{     
      msg = "TEXT"[B][COLOR="Red"],[/COLOR][/B]
      pos = {x=693, y=1007, z=7},
      typ = 0 -- I guess :|
}       
       
[B]function onLogin(cid)[/B]
    doPlayerPopupFYI(cid, t.msg)
    doPlayerAddMapMark(cid, t.pos, t.typ)
    return TRUE
[B]end[/B]

okay, didn't know that xd

Cloow · Jul 9, 2010

So my script should be like this -

PHP:

local t = 
{     
      msg = "TEXT",
      pos = {x=693, y=1007, z=7},
	  typ = "0"
}	   
	   
function onLogin(cid) <-- Not sure if "STARTER_OUTFITID" should be here to ?
  doPlayerPopupFYI("STARTER_OUTFITID", t.msg)
    doPlayerAddMapMark("STARTER_OUTFITID", t.pos, t.typ, "NPC NAME")
	return TRUE
end

right hm ?

WibbenZ · Jul 9, 2010

Lua:

   local text = "Welcome! Young master, if you go north east from here you reach Dr. Oak's lab. Talk with him and get your starting pokemon!", 
   local position = {x=693, y=1007, z=7}, 
   local type = "0"  
   
function onLogin(cid)
  return doPlayerPopupFYI(STARTER_OUTFITID, text) and doPlayerAddMapMark(STARTER_OUTFITID, position, type, "Dr. Oak") 
end

In order to that you need to use a storage value.

Code:

local t = 
{     
	storage = 15012,
    msg = "TEXT",
    pos = {x=693, y=1007, z=7},
    typ = 0 -- I guess :|
}       
       
function onLogin(cid)
	if getPlayerStorageValue(cid,t.storage) < 0 then -- this will check if your value is -1.
		setPlayerStorageValue(cid,t.storage,1) -- here you set it above the value 0 so that it will skip it the next time.
		doPlayerPopupFYI(cid, t.msg)
		doPlayerAddMapMark(cid, t.pos, t.typ)
	end
    return TRUE
end

you can still do it in login.lua though.

just paste these lines.

Code:

if getPlayerStorageValue(cid,t.storage) < 0 then -- this will check if your value is -1.
		setPlayerStorageValue(cid,t.storage,1) -- here you set it above the value 0 so that it will skip it the next time.
		doPlayerPopupFYI(cid, t.msg)
		return doPlayerAddMapMark(cid, t.pos, t.typ)
	end
