Lua Summon scroll request

[sick]

So i was looking for something like summon scroll around forums and couldn't find one, so made this thread hoping someone has one or will try to do it.

The idea is that you use scroll and it summons you, lets say, demon skeleton, you loose like 500 mana and can have 2 summons at time. They act like you would say utevo res~( listens/follows you ) and the scroll has like 20 charges, after that it becomes blank piece of paper.

I don't want to enable simple summon spell cause it would ruin pvp at my server, summons has to be some kind of special thing :>

Thanks in advance :thumbup:

local config = {
	monster = "Demon Skeleton",
	charges = 20,
	manaCost = 500,
	maxSummons = 2
}

function onUse(cid, item, fromPosition, itemEx, toPosition)
	if(getCreatureSummons(cid) >= config.maxSummons) then
		return false
	end

	if(getCreatureMana(cid) < config.manaCost) then
		return false
	end

	if(item.actionid <= 0) then
		doItemSetAttribute(item.uid, "aid", config.charges - 1)
	elseif(item.actionid == 1) then
		doRemoveItem(item.uid)
	else
		doItemSetAttribute(item.uid, "aid", item.actionid - 1)
	end

	local monster = doCreateMonster(config.monster, fromPosition)
	doConvinceCreature(monster)
	doCreatureAddMana(cid, -config.manaCost)
	return true
end

Oh I forgot hash character, here's fixed version:

local config = {
	monster = "Demon Skeleton",
	charges = 20,
	manaCost = 500,
	maxSummons = 2
}

function onUse(cid, item, fromPosition, itemEx, toPosition)
	if(#getCreatureSummons(cid) >= config.maxSummons) then
		return false
	end

	if(getCreatureMana(cid) < config.manaCost) then
		return false
	end

	if(item.actionid <= 0) then
		doItemSetAttribute(item.uid, "aid", config.charges - 1)
	elseif(item.actionid == 1) then
		doRemoveItem(item.uid)
	else
		doItemSetAttribute(item.uid, "aid", item.actionid - 1)
	end

	local monster = doCreateMonster(config.monster, fromPosition)
	doConvinceCreature(monster)
	doCreatureAddMana(cid, -config.manaCost)
	return true
end

Now the errors are cleared, however when i try using it, console says that:

[05/09/2010 18:27:30] [Error - Action Interface] 
[05/09/2010 18:27:30] data/actions/scripts/other/summonscroll.lua:onUse

I tried using simple convince creature rune and it works, it finds all the monsters but using this item it doesn't ;s

My fault, again :

local config = {
	monster = "Demon Skeleton",
	charges = 20,
	manaCost = 500,
	maxSummons = 2
}

function onUse(cid, item, fromPosition, itemEx, toPosition)
	if(#getCreatureSummons(cid) >= config.maxSummons) then
		return false
	end

	if(getCreatureMana(cid) < config.manaCost) then
		return false
	end

	if(item.actionid <= 0) then
		doItemSetAttribute(item.uid, "aid", config.charges - 1)
	elseif(item.actionid == 1) then
		doRemoveItem(item.uid)
	else
		doItemSetAttribute(item.uid, "aid", item.actionid - 1)
	end

	local monster = doCreateMonster(config.monster, fromPosition)
	doConvinceCreature(cid, monster)
	doCreatureAddMana(cid, -config.manaCost)
	return true
end

Damn, whats wrong with it i don't get it ;s Almost nothing changed, just now a new error appeared : Cannot create monster: Demon Skeleton.

Tried editing it lots if times, however I'm not good at these scripts yet, so don't even know whats wrong

 

[chojrak]

Try with this:

local monster = doCreateMonster(config.monster, fromPosition, true)

 

[sick]

Still nothing changed ;/

P.S thanks for trying to help me

 

[sick]

Anyone know whats wrong with the script?

 

[sick]

Someone?

 

[JDB]

local config = {
	[xxxx] = { -- # SCROLL ID # --
		monster = "Demon Skeleton",
		charges = 20,
		mana = 500,
		summons = 2
	}
}

function onUse(cid, item, fromPosition, itemEx, toPosition)
        local v = config[item.itemid]
	if table.maxn(getCreatureSummons(cid)) >= v.summons then
		return doPlayerSendDefaultCancel(cid, RETURNVALUE_NOTPOSSIBLE)
	end

	if getCreatureMana(cid) < v.mana then
		return doPlayerSendDefaultCancel(cid, RETURNVALUE_NOTPOSSIBLE)
	end

	if item.actionid <= 0 then
		doItemSetAttribute(item.uid, "aid", v.charges - 1)
	elseif item.actionid == 1 then
		doRemoveItem(item.uid)
	else
		doItemSetAttribute(item.uid, "aid", item.actionid - 1)
	end

	return doPlayerAddMana(cid, - v.mana) and doSummonMonster(v.monster, getCreaturePosition(cid).x + 1)
end

Something is wrong, it says :

[sick]

Like always... ;/
(luaDoSummonMonster) Creature not found

 

[Ecstacy]

try this, fixed doSummonCreature in script from JDB.

local config = {
	[xxxx] = { -- # SCROLL ID # --
		monster = "Demon Skeleton",
		charges = 20,
		mana = 500,
		summons = 2
	}
}

function onUse(cid, item, fromPosition, itemEx, toPosition)
        local v = config[item.itemid]
	if table.maxn(getCreatureSummons(cid)) >= v.summons then
		return doPlayerSendDefaultCancel(cid, RETURNVALUE_NOTPOSSIBLE)
	end

	if getCreatureMana(cid) < v.mana then
		return doPlayerSendDefaultCancel(cid, RETURNVALUE_NOTPOSSIBLE)
	end

	if item.actionid <= 0 then
		doItemSetAttribute(item.uid, "aid", v.charges - 1)
	elseif item.actionid == 1 then
		doRemoveItem(item.uid)
	else
		doItemSetAttribute(item.uid, "aid", item.actionid - 1)
	end

	return doPlayerAddMana(cid, - v.mana) and doSummonMonster(cid,v.monster)
end

By the is it possible to make it to show how many charges left on it when pressed and if charges are out it doesn't disappear but becomes to piece of paper ( lets say becomes to id: 1954 )
