AddEvent

[Fare]

hey guys, I can't understand how addEvent works, for example I trying to make spell:

local combat1 = createCombatObject()
setCombatParam(combat1, COMBAT_PARAM_TYPE, COMBAT_UNDEFINEDDAMAGE)
setCombatParam(combat1, COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)
setCombatFormula(combat1, COMBAT_FORMULA_LEVELMAGIC, -0.6, -30, -1.2, 0)
 
local combat2 = createCombatObject()
setCombatParam(combat2, COMBAT_PARAM_TYPE, COMBAT_MANADRAIN)
setCombatParam(combat2, COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)
setCombatFormula(combat2, COMBAT_FORMULA_LEVELMAGIC, -0.6, -30, -1.2, 0)
 
local combat3 = createCombatObject()
setCombatParam(combat3, COMBAT_PARAM_TYPE, COMBAT_LIFEDRAIN)
setCombatParam(combat3, COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)
setCombatFormula(combat3, COMBAT_FORMULA_LEVELMAGIC, -0.6, -30, -1.2, 0)
 
local combat4 = createCombatObject()
setCombatParam(combat4, COMBAT_PARAM_TYPE, COMBAT_POISONDAMAGE)
setCombatParam(combat4, COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)
setCombatFormula(combat4, COMBAT_FORMULA_LEVELMAGIC, -0.6, -30, -1.2, 0)
 
local combat5 = createCombatObject()
setCombatParam(combat5, COMBAT_PARAM_TYPE, COMBAT_FIREDAMAGE)
setCombatParam(combat5, COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)
setCombatFormula(combat5, COMBAT_FORMULA_LEVELMAGIC, -0.6, -30, -1.2, 0)
 
local combat6 = createCombatObject()
setCombatParam(combat6, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat6, COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)
setCombatFormula(combat6, COMBAT_FORMULA_LEVELMAGIC, -0.6, -30, -1.2, 0)
 
local combat7 = createCombatObject()
setCombatParam(combat7, COMBAT_PARAM_TYPE, COMBAT_DROWNDAMAGE)
setCombatParam(combat7, COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)
setCombatFormula(combat7, COMBAT_FORMULA_LEVELMAGIC, -0.6, -30, -1.2, 0)
 
local combat8 = createCombatObject()
setCombatParam(combat8, COMBAT_PARAM_TYPE, COMBAT_ENERGYDAMAGE)
setCombatParam(combat8, COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)
setCombatFormula(combat8, COMBAT_FORMULA_LEVELMAGIC, -0.6, -30, -1.2, 0)
 
arr1 = {
{0, 0, 0},
{0, 2, 0},
{0, 0, 1},
}
 
arr2 = {
{0, 0, 0},
{0, 2, 0},
{0, 1, 0},
}
 
arr3 = {
{0, 0, 0},
{0, 2, 0},
{1, 0, 0},
}
 
arr4 = {
{0, 0, 0},
{1, 2, 0},
{0, 0, 0},
}
 
arr5 = {
{1, 0, 0},
{0, 2, 0},
{0, 0, 0},
}
 
arr6 = {
{0, 1, 0},
{0, 2, 0},
{0, 0, 0},
}
 
arr7 = {
{0, 0, 1},
{0, 2, 0},
{0, 0, 0},
}
 
arr8 = {
{0, 0, 0},
{0, 2, 1},
{0, 0, 0},
}
 
 
local area1 = createCombatArea(arr1)
local area2 = createCombatArea(arr2)
local area3 = createCombatArea(arr3)
local area4 = createCombatArea(arr4)
local area5 = createCombatArea(arr5)
local area6 = createCombatArea(arr6)
local area7 = createCombatArea(arr7)
local area8 = createCombatArea(arr8)
 
setCombatArea(combat1, area1)
setCombatArea(combat2, area2)
setCombatArea(combat3, area3)
setCombatArea(combat4, area4)
setCombatArea(combat5, area5)
setCombatArea(combat6, area6)
setCombatArea(combat7, area7)
setCombatArea(combat8, area8)
 
 
local function onCastSpell1(parameters)
 doCombat(parameters.cid, parameters.combat1, parameters.var)
end
 
local function onCastSpell2(parameters)
 doCombat(parameters.cid, parameters.combat2, parameters.var)
end
 
local function onCastSpell3(parameters)
 doCombat(parameters.cid, parameters.combat3, parameters.var)
end
 
local function onCastSpell4(parameters)
 doCombat(parameters.cid, parameters.combat4, parameters.var)
end
 
local function onCastSpell5(parameters)
 doCombat(parameters.cid, parameters.combat5, parameters.var)
end
 
local function onCastSpell6(parameters)
 doCombat(parameters.cid, parameters.combat6, parameters.var)
end
 
local function onCastSpell7(parameters)
 doCombat(parameters.cid, parameters.combat7, parameters.var)
end
 
local function onCastSpell8(parameters)
 doCombat(parameters.cid, parameters.combat8, parameters.var)
end
 
function spellCallbackExoriAura(cid, var)
local param = 0
 local parameters = { cid = cid, var = var, combat1 = combat1, combat2 = combat2, combat3 = combat3, combat4 = combat4, combat5 = combat5, combat6 = combat6, combat7 = combat7, combat8 = combat8 }
 addEvent(onCastSpell1, 1, parameters)
 addEvent(onCastSpell2, 700, parameters)
 addEvent(onCastSpell3, 200, parameters)
 addEvent(onCastSpell4, 300, parameters)
 addEvent(onCastSpell5, 600, parameters)
 addEvent(onCastSpell6, 500, parameters)
 addEvent(onCastSpell7, 100, parameters)
 addEvent(onCastSpell8, 400, parameters)
 end
 
 
 function onCastSpell(cid, var)
	 local parameters = { cid = cid, var = var }
	addEvent(spellCallbackExoriAura, 2000, parameters)
end

and got this error:

19/07/2008  13:44:43] Lua Script Error: [Spell Interface]

can anybody explain how addEvent works?

 

[slaw]

Try:

function spellCallbackExoriAura(cid, var)

To:

function spellCallbackExoriAura(cid, params)

And:

local parameters = {cid = params.cid, var = params.var, combat1 = combat1, combat2 = combat2, combat3 = combat3, combat4 = combat4, combat5 = combat5, combat6 = combat6, combat7 = combat7, combat8 = combat8}
