Lua Disallow player to attacking some players

[Warmix]

Hello,
I want to disallow player to attacking other palyers with e.g. StorageValue==1000. Using TFS 0.4 I might put this codition in creatrurescripts, but now I'm using TFS 1.2 and doCombat doesn't exist in creaturescripts. Where can I do something like that?

in events/creature.lua

function Creature:onTargetCombat(target)
if self:isPlayer() and target:isPlayer() then
  if target:getStorageValue(1111) >= 1 then
    return RETURNVALUE_YOUMAYNOTATTACKTHISPLAYER
  end
end
   return true
end
