Actor:takeHit Hook
Posted: Sat Mar 14, 2015 4:41 pm
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:
Using this gives the following error:
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)Code: Select all
