Help! On spell base on health % being used

[krankthefunk]

Hi want to know how to make a spell that let's say you have 1000 Hp,
And the spell uses 5% of your health, so it has a base damage + 5% of your health are being converted into damage, but it drain 5% of your health while being used. How would this be done?

Thanks!

in spells.xml set mana to whatever you like.
but in spell script (in lua) use something like that:

function onCastSpell(cid, var)

local cPos = getCreaturePosition(getCreatureTarget(cid))

local hp = getPlayerMaxHealth(cid)
local basedmg = 200
local hppercent = 5
local totaldmg = basedmg+(hp/100)*hppercent

if hp > (hp/100)*hppercent then
	doSendDistanceShoot(getCreaturePosition(cid), cPos, CONST_ANI_FIRE)
	doTargetCombatHealth(cid, getCreatureTarget(cid), COMBAT_FIREDAMAGE, -totaldmg, -totaldmg, CONST_ME_FIREAREA)
	doPlayerAddHealth(cid, -(hp/100)*hppercent)
else
return false
end
return true
end
