Lua [0.4] Ammo Enchantment

[potinho]

Good morning guys,

I have a 7.6 server and I wanted to create an action (rune or magic) that would enchant the ammunition I'm using (it would only work for paladins) and would turn that ammunition, for a while, into something like Tibia Global's diamond arrows. This enchantment would cause the ammo to do area damage, halving single target damage. can you help me?

 

[zbizu]

try looking at enchant staff spell code and seeing if you can apply it to ammo slot

code for area arrows can be found in burst arrow file

 

[potinho]

tried, it didn't work. I want this effect to last a predetermined time

Ammunition is stackable, so therefore cannot be enchanted or modified directly, because the moment anything regarding the stack changes (firing an arrow, moving the stack of items, or separating the stack into 2 smaller stacks) the server reverts everything back to a regular ammo stack. This is a stackable item issue, more then an ammunition issue.

A possible alternative would be to give your character a buff (using a spell/rune/item) which inside of your weapon script, could convert all ammunition into diamond arrows (visually only) by using a new combat, but would still drain the regular ammunition. (combat1 = regular ammo, single target) (combat2 = buff, aoe, half damage)

This alternative would help me perfectly Xikini, can you help me implement this?

buff item example

<action itemid="11111111" event="script" value="aaaaaaaa.lua"/>

local buffTime = 10 -- seconds
local buffStorageKey = 45001

function onUse(cid, item, fromPosition, itemEx, toPosition)
    local newTime = buffTime + os.time()
    doCreatureSetStorage(cid, buffStorageKey, newTime)
    doCreatureSay(cid, "Buffed for " .. buffTime .. " seconds!", TALKTYPE_MONSTER)
    doRemoveItem(item.uid, 1)
    return true
end

And then inside your weapon scripts, setup 2 combats. (combat1, combat2)
For this example, I've used poison arrow for the regular attack, and burst arrow for the buffed attack.

local buffStorageKey = 45001

-- combat 1
local combat1 = createCombatObject()
setCombatParam(combat1, COMBAT_PARAM_BLOCKARMOR, 1)
setCombatParam(combat1, COMBAT_PARAM_TYPE, COMBAT_POISONDAMAGE)
setCombatParam(combat1, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_POISONARROW)
setCombatFormula(combat1, COMBAT_FORMULA_SKILL, 1, 0, 1, 0)

local condition = createConditionObject(CONDITION_POISON)
setConditionParam(condition, CONDITION_PARAM_DELAYED, 1)
addDamageCondition(condition, 10, 2000, -1)
setCombatCondition(combat1, condition)

-- combat 2
local combat2 = createCombatObject()
setCombatParam(combat2, COMBAT_PARAM_BLOCKARMOR, 1)
setCombatParam(combat2, COMBAT_PARAM_BLOCKSHIELD, 1)
setCombatParam(combat2, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat2, COMBAT_PARAM_EFFECT, CONST_ME_FIREAREA)
setCombatParam(combat2, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_BURSTARROW)
setCombatFormula(combat2, COMBAT_FORMULA_SKILL, 1, 0, 1, 0)

local area = createCombatArea({
    {1, 1, 1},
    {1, 3, 1},
    {1, 1, 1}
})

setCombatArea(combat2, area)

function onUseWeapon(cid, var)
    if getCreatureStorage(cid, buffStorageKey) >= os.time() then
        return doCombat(cid, combat2, var) -- buffed
    end
    return doCombat(cid, combat1, var) -- regular
end

end

Thank you so very much, again
