Lua doCombat(cid, combat, VAR?)

[andu]

doCombat(cid, combat, var) - what "var" means? And how to add "doCombat" into onUse function?

e.g. script:

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_BLOCKARMOR, 1)
setCombatParam(combat, COMBAT_PARAM_BLOCKSHIELD, 1)
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, 2)
setCombatFormula(combat, COMBAT_FORMULA_SKILL, 2.5, 0, 3.5, 0)

function onUse(cid, item, frompos, item2, topos)
	local var = ?????
	doCombat(cid, combat, var)
	return true
end

Var is like the target, on what the combat should effect.
So you can do for example

doCombat(cid, combat, numberToVariant(item2.uid))

Or if it's for the person who is using the item

doCombat(cid, combat, numberToVariant(cid))

 

[Teckman]

Variant can be either string, position or number. It determines how doCombat should be executed.

I made a spell using this parameter, it helped me find the target's position and teleport me to him/her.

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_ASSASSIN)
setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_NONE)
setCombatFormula(combat, COMBAT_FORMULA_LEVELMAGIC, -1, -10, -1, -20, 5, 5, 1.4, 2.1)
 
local function delayedTeleport(cid, position)
	if(not isCreature(cid)) then return true end
	doTeleportThing(cid, position)
	return true
end
 
function onCastSpell(cid, var)
	addEvent(delayedTeleport, 500, cid, getCreaturePosition(cid))
	doSendMagicEffect(getCreaturePosition(cid), CONST_ME_POFF)
	doTeleportThing(cid, getThingPos(variantToNumber(var)), true)
	return doCombat(cid, combat, var)
end

In here, I used var to get the position of the target player.
I converted the var into a number (which is some kind of player ID in the game), then used this in getThingPos() to get the position.

There's a lot of different ways you can use it.
