Solved function onCastSpell(cid, var) - is it possible to get target?

[okurde]

Hello, there is heal friend script:

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_HEALING)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_BLUE)
setCombatParam(combat, COMBAT_PARAM_AGGRESSIVE, false)
setCombatParam(combat, COMBAT_PARAM_DISPEL, CONDITION_PARALYZE)
setHealingFormula(combat, COMBAT_FORMULA_LEVELMAGIC, 5, 5, 10, 14)

function onCastSpell(cid, var)
        return doRemoveCondition(cid, CONDITION_PARALYZE), doCombat(cid, combat, var)
end

Is there any way to get a target (player who is healed) and allow to heal only player with level lower than 80?

You didn't say the server version.

#edit:
I'm not much into TFS lower than 1.0(don't know much functions ), but try this.

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_HEALING)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_BLUE)
setCombatParam(combat, COMBAT_PARAM_AGGRESSIVE, false)
setCombatParam(combat, COMBAT_PARAM_DISPEL, CONDITION_PARALYZE)
setHealingFormula(combat, COMBAT_FORMULA_LEVELMAGIC, 5, 5, 10, 14)

function onCastSpell(cid, var)
    local target = Player(stringToVariant(var))
    if target and getPlayerLevel(target) <= 80 then
        return doRemoveCondition(cid, CONDITION_PARALYZE), doCombat(cid, combat, var)
    else
        doPlayerSendCancel(cid, "You can only heal players with level 80 or below.")
    end
end

Maybe it will work i have no idea, but it is a start..

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_HEALING)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_BLUE)
setCombatParam(combat, COMBAT_PARAM_AGGRESSIVE, false)
setCombatParam(combat, COMBAT_PARAM_DISPEL, CONDITION_PARALYZE)
setHealingFormula(combat, COMBAT_FORMULA_LEVELMAGIC, 5, 5, 10, 14)

local function doHealPlayer(cid, pos)
    local getPos = pos
    getPos.stackpos = STACKPOS_TOP_CREATURE

    local target = getThingFromPos(getPos)
    if target.uid ~= 0 then
        if isPlayer(target.uid) then
            if getPlayerLevel(target.uid) < 80 then
                doSendMagicEffect(pos, CONST_ME_MAGIC_BLUE)
                return doCombat(cid, combat, var)
            end
        end
    end
  
    doSendMagicEffect(getPlayerPosition(cid), CONST_ME_POFF)
    doPlayerSendDefaultCancel(cid, RETURNVALUE_NOTPOSSIBLE)
    return false
end

function onCastSpell(cid, var)
    local pos = variantToPosition(var)
    if(pos.x ~= 0 and pos.y ~= 0) then
        return doHealPlayer(cid, pos)
    end
    return false
end

here, easy as eating a pie

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_HEALING)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_BLUE)
setCombatParam(combat, COMBAT_PARAM_AGGRESSIVE, false)
setCombatParam(combat, COMBAT_PARAM_DISPEL, CONDITION_PARALYZE)
setHealingFormula(combat, COMBAT_FORMULA_LEVELMAGIC, 5, 5, 10, 14)

function onCastSpell(cid, var)
    if getPlayerLevel(var.number) >= 80 then      
        return false, doPlayerSendCancel(cid, "Sorry, you may only cast this on players below level 80.")
    end
  
    return doCombat(cid, combat, var)
end

Okay thanks, it almost works How can I get position of target?

Well, I did:

local target = getPlayerByNameWildcard(var)

if getPlayerLevel(target) < 80        -- works
if getTilePzInfo(getPlayerPosition(target)) -- does not work

data/spells/scripts/healing/heal friend.luanCastSpell
Description:
data/lib/100-shortcut.lua:304: attempt to index a boolean value
stack traceback:
data/lib/100-shortcut.lua:304: in function 'getTilePzInfo'



I tried:

local target = getPlayerByNameWildcard(var) 
local posTarget = variantToPosition(var)

but

getTilePzInfo(getPlayerPosition(posTarget)) -- still does not work

@cbrm
Awseom! Is is possible to get position in such simple way?

 

[hodleo]

var is a table that contains the values type and number in the case of that spell
number is the target's creature id so you don't need to get or define it again

You can get the position of target with:

getThingPosition(var.number)

Awesome! Thank you guys )
