Modding Help Preventing healing items for certain race

Hello. I am making a custom race that heals when enemy gets hit. So, to balance this mechanic I want this race not be able to use usual healing items (there will be their individual expensive ones).

So I have "lifesteal" status effect on race permanently and I need to check its existence on character in heal.lua, so if it exists effect.expire() activates. But I can't imagine how to do that. I tried using player.species() but it didn't work at all. As I learned from forum it's kinda bugged or smth.

heal.lua edit:

function init()
animator.setParticleEmitterOffsetRegion("healing", mcontroller.boundBox())
animator.setParticleEmitterEmissionRate("healing", config.getParameter("emissionRate", 3))
animator.setParticleEmitterActive("healing", true)

script.setUpdateDelta(5)

self.healingRate = config.getParameter("healAmount", 30) / effect.duration()
if //check for lifesteal effect?// then
effect.expire()
end
end

function update(dt)
status.modifyResource("health", self.healingRate * dt)
end

function uninit()
end

 

Found a way to realise that. If anyone needs I will leave my code example. So there I am checking for effect named lifesteal in heal.lua from original game files. When lifesteal effect is on the player, heal effect instantly expires.

Code:

function init()
  animator.setParticleEmitterOffsetRegion("healing", mcontroller.boundBox())
  animator.setParticleEmitterEmissionRate("healing", config.getParameter("emissionRate", 3))
  animator.setParticleEmitterActive("healing", true)

  script.setUpdateDelta(5)

  self.healingRate = config.getParameter("healAmount", 30) / effect.duration()
end

function update(dt)
  status.modifyResource("health", self.healingRate * dt)

  effects = status.activeUniqueStatusEffectSummary()
  if (#effects > 0) then
    for i=1, #effects do
      if (effects[i][1] == "lifesteal") then
        effect.expire()
      end
    end     
  end
end

function uninit()

end
