Entity Takes Damage

[blackfire88]

I am scripting an entity and I want it to so some things when it takes damage. The data I need to get is the Weapon of the attacker, the attacker and the damage given.
Help appreciated :)

For a gamemode, you can use
[lua]function GM:EntityTakeDamage(ent, wep, attacker, dmg, dmginfo)
--stuff
end[/lua]

Otherwise, [lua]hook.Add("EntityTakeDamage","SomeHookNameHere", function(ent, wep, attacker, dmg, dmginfo)
--stuff
end)[/lua]

Hmm well, i'm putting it in a scripted entity.
If i put it inside init.lua, will it work or will there be like 50 of the same hook
I need to make it so that it only affects that certain entity.
(its a tree you chop down)
I used your code but if i tried to chop down a tree all the trees would be chopped down.
Im sure im using it wrong can someone help?

Oh, if it's just one sent, try:
[lua]function ENT:OnTakeDamage( dmginfo )
local dmg = dmginfo:GetDamage()
local wep = dmginfo:GetInflictor()
local attacker = dmginfo:GetAttacker()
--stuff
end[/lua]

The GetInflictor deosnt work, i did this:
[lua]
attacker:ChatPrint(wep)
[/lua]'
and it said
Bad argument expected string got player

Im trying to print the weapon used.
Bump

attacker:SendLua("LocalPlayer():ChatPrint(wep:GetPrintName())")

Used SendLua because GetPrintName is clientside.

Yes but I need to use it in a serverside script as well.
