Actor:takeHit Hook

[Razakai]

I'm trying to create a talent that works in a similar manner to bloated oozes, namely summoning a few NPCs that while active will split damage among the player. The talent itself seems ok, but I just can't seem to get the hook working:

Code: Select all

class:bindHook("Actor:takeHit", function(self,data)		
		if value > 0 and self:hasEffect(self.EFF_LIFELINK) then
			local acts = {}
			if game.party:hasMember(self) then
				for act, def in pairs(game.party.members) do
					if act.summoner and act.summoner == self and act.cghoul then acts[#acts+1] = act end
				end
			else
				for _, act in pairs(game.level.entities) do
					if act.summoner and act.summoner == self and act.cghoul then acts[#acts+1] = act end
				end
			end
			if #acts > 0 then
				game:delayedLogMessage(self, nil, "lifelink_damage", "#DARK_GREEN##Source# shares damage with %s ghouls!", string.his_her(self))
				value = value / (#acts+1)
				for _, act in ipairs(acts) do
					act:takeHit(value, src)
				end
			end
		end
end)

Using this gives the following error:

Code: Select all

Don't you need data.value instead of value?

If it's something that simple I'll feel rather silly. Thanks for the advice, I'll try it out when I get back to my main PC.
