Lua Creature not found

[Hypomania]

Hi,

I was wondering how to make a version of exori which follows the player for a couple of seconds. Here is my current version (I get the creature not found error):

local combat1 = createCombatObject()
setCombatParam(combat1, COMBAT_PARAM_TYPE, COMBAT_FIREDAMAGE)
setCombatParam(combat1, COMBAT_PARAM_EFFECT, 6)
setCombatFormula(combat1, COMBAT_FORMULA_LEVELMAGIC, -0.7, -30, -0.7, -0)

local combat2 = createCombatObject()
setCombatParam(combat2, COMBAT_PARAM_TYPE, COMBAT_FIREDAMAGE)
setCombatParam(combat2, COMBAT_PARAM_EFFECT, 6)
setCombatFormula(combat2, COMBAT_FORMULA_LEVELMAGIC, -0.7, -30, -0.7, -0)

local combat3 = createCombatObject()
setCombatParam(combat3, COMBAT_PARAM_TYPE, COMBAT_FIREDAMAGE)
setCombatParam(combat3, COMBAT_PARAM_EFFECT, 6)
setCombatFormula(combat3, COMBAT_FORMULA_LEVELMAGIC, -0.7, -30, -0.7, -0)

arr1 = {
    {0, 0, 0, 0, 0},
    {0, 1, 1, 1, 0},
    {0, 1, 2, 1, 0},
    {0, 1, 1, 1, 0},
    {0, 0, 0, 0, 0}
}


local area1 = createCombatArea(arr1)
local area2 = createCombatArea(arr2)
local area3 = createCombatArea(arr3)
setCombatArea(combat1, area1)
setCombatArea(combat2, area1)
setCombatArea(combat3, area1)


function onCastSpell1(parameters)
    doCombat(parameters.cid, parameters.combat1, parameters.var, positionToVariant(getCreaturePosition(cid)))
end

function onCastSpell2(parameters)
    doCombat(parameters.cid, parameters.combat2, parameters.var, positionToVariant(getCreaturePosition(cid)))
end

function onCastSpell3(parameters)
    doCombat(parameters.cid, parameters.combat3, parameters.var, positionToVariant(getCreaturePosition(cid)))
end

function onCastSpell(cid, var) 
local parameters = { cid = cid, var = var, combat1 = combat1, combat2 = combat2, combat3 = combat3 }

addEvent(onCastSpell1, 1, parameters) 
addEvent(onCastSpell2, 500, parameters) 
addEvent(onCastSpell3, 1000, parameters) 

return true
end

Anyone?

Thanks for the response, but it still gives the same error. Also, yes, there is a isCreature(cid) function.

Wow, that seems to work perfectly, thank you very much!

 

[Hypomania]

Could you also please explain why it didn't work before? Also, what is exactly is "var" or "variant"?

There are only 3 parameters in doCombat, cid, combat & var, initially we had 4, since positionToVariant(getCreaturePosition(cid)) was the intended value to pass as an argument to doCombat, var needed to be replaced with the value returned from positionToVariant, so that it may be passed the proper data to doCombat.

Variant is a table of position and maybe other data, run a for loop over it to see what values it holds, sorry i don't write or test the code using a server

Thank you a lot, that was really useful
