Is there a way to "intercept" weapon damage ?

[desalib]

Hello everyone,

I want to know if there is a way to intercept ALL damage dealt by weapons use. (using weapon script maybe?)

I have this script (posted by neon)

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)
 
-- this function is used to determine the damage done on a hit
function onGetFormulaValues(cid, level, skill, attack, element, factor)
    local rebs = getPlayerStorageValue(cid, 85987)
	if rebs < 1 then 
	    rebs = 1
	end -- this if condition must be used , because if it isn't the weapon damage will be 0 on 0 rebirth players
    local formula = ((rebs*xx)*-1) -- change xx to be how much damage you want per rebirth
	return formula/2, formula*1.5
end
setCombatCallback(combat, CALLBACK_PARAM_SKILLVALUE, "onGetFormulaValues")
-- function ends here
 
function onUseWeapon(cid, var)
	return doCombat(cid, combat, var)
end

It's easy to modify the damage output this way but I want a way to clearly get the damage dealt.
That I may set to 0 with a condition maybe? Or do another action acording the damage dealt.
I'm open to source edit.
