Script summon monster from item with charges

[Jester753]

This script should summon a demon from a lamp, 3 times then run out of charges but it won't work.

heres my code:

local config=
{
monster="Demon"
i=3
}

function onUse(cid, item, frompos, itemEx, topos)
if config.i >0 then
if item.itemid == 2063 then
doSummonCreature(config.demon, getCreaturePosition(cid))
config.i-1
doPlayerSendTextMessage(cid,21,"It works !")
else
doPlayerSendTextMessage(cid, 21, "It still doesn't work!")
end
else
doPlayerSendTextMessage(cid, 21, "Your item has ran out of charges")
end

return TRUE
end


thanks

Sorry no time to test it but i managed to fix the error:

local otswe= {
create_monster = "Demon"
}

function onUse(cid, item, frompos, itemEx, topos)
if item.itemid == 2063 then
doSummonCreature(otswe.create_monster, getCreaturePosition(cid))
doPlayerSendTextMessage(cid,21,"You have summoned 1 Demon!")
else
doPlayerSendTextMessage(cid, 21, "It still doesn't work!")
end
return true
end

local config = {
   monsterName = "Demon",
   charges = 3
}
 
function onUse(cid, item, frompos, itemEx, topos)
   if item.itemid ~= 2063 then
      return false
   end

   if config.charges > 0 then
      config.charges -= 1
      doSummonCreature(config.monsterName, getCreaturePosition(cid))
      doPlayerSendTextMessage(cid, 21, "You rub the lamp. A dark force rises to obey your every command.")
   else
      doPlayerSendTextMessage(cid, 21, "Your item has ran out of charges")
   end
   return true
end

Fixed some obvious mistakes, but this probably still won't work.

This may be the one you are looking for.

function onUse(cid, item, frompos, item2, topos)
	local charges = 3
	local mob = "Demon"
	local maxSummons = 1
	
	if(getPlayerStorageValue(cid, item.itemid) < charges) then
		if(getTilePzInfo(getCreaturePosition(cid)) == false) then
			if(table.maxn(getCreatureSummons(cid)) < maxSummons) then
				doSummonMonster(cid, mob)
				setPlayerStorageValue(cid, item.itemid, getPlayerStorageValue(cid, item.itemid) + 1)
				doPlayerSendTextMessage(cid, 19, "You successfully summoned a ".. mob .."!")
			else
				doPlayerSendCancel(cid, "You can only summon up to ".. maxSummons .." ".. mob .."s.")
				return false
			end
		else
			doPlayerSendCancel(cid, "You cannot summon in protecting zone.")
			return false
		end
	else
		doPlayerSendCancel(cid, "You have used all charges this lamp contains.")
		return false
	end
	
	return true
end

Thanks guys, sorry i just started learning lua scripts. I'm used to C++ so it's a little difficult to switch.

- - - Updated - - -

If i wanted to clear the amount of charges the player has used, lets say if they talked to an npc or something. Would i use this line of code? (using warofthetitans code)

setPlayerStorageValue(cid, item.actionid, getPlayerStorageValue(cid, item.actionid) - 3)

instead if "item.itemid" change it to an ordinary storage.

 

[Jester753]

Sorry, how would i go about that?

 

[WarOfTheTitans]

function onUse(cid, item, frompos, item2, topos)
	local charges = 3
	local mob = "Demon"
	local maxSummons = 1
 
        local str = 111
	if(getPlayerStorageValue(cid, str) < charges) then
		if(getTilePzInfo(getCreaturePosition(cid)) == false) then
			if(table.maxn(getCreatureSummons(cid)) < maxSummons) then
				doSummonMonster(cid, mob)
				setPlayerStorageValue(cid, str, getPlayerStorageValue(cid, str) + 1)
				doPlayerSendTextMessage(cid, 19, "You successfully summoned a ".. mob .."!")
			else
				doPlayerSendCancel(cid, "You can only summon up to ".. maxSummons .." ".. mob .."s.")
				return false
			end
		else
			doPlayerSendCancel(cid, "You cannot summon in protecting zone.")
			return false
		end
	else
		doPlayerSendCancel(cid, "You have used all charges this lamp contains.")
		return false
	end
 
	return true
end
