[roriscrave]

Hi, i make one script, that i need to check a storage of Demon, when he have 50% of hp, and set this storage to 1:

function onHealthChange(creature, attacker, primaryDamage, primaryType, secondaryDamage, secondaryType, origin)
    local health, maxHealth = creature:getHealth(), creature:getMaxHealth()
    local percent = health/maxHealth * 100
    if percent <= 50 and creature:getStorageValue(4954) ~= 1 then
        creature:setStorageValue(4954, 1)
    end

    return primaryDamage, primaryType, secondaryDamage, secondaryType
end

but i get this error:

Lua Script Error: [CreatureScript Interface]
data/creaturescripts/scripts/test.lua:onHealthChange
data/creaturescripts/scripts/test.lua:4: attempt to call method 'getStorageValue' (a nil value)
stack traceback:
        [C]: in function 'getStorageValue'
        data/creaturescripts/scripts/test.lua:4: in function <data/creaturescripts/scripts/test.lua:1>
        [C]: at 0x7ff79dda00d0

its not possible to set a storage to a monster?
I need to demon summon 5 fire elementals, when he have 50% hp, and summon only 1x
