Creating an entity with a script, and then adding a hook to it?

[VladimirMurphy]

This snippet of code is from a Banana Peel entity I found on the Toybox forever ago, and I'm making a few modifications to make it work in TTT.

 local ragdoll = ents.Create( "prop_ragdoll" ); --prop_ragdoll 
            ragdoll:SetPos( ent:GetPos( ) + Vector( 0, 0, 5 ) );
            ragdoll:SetAngles( Angle( 0, ent:GetAngles( ).Yaw, 0 ) );
			ragdoll:SetModel( ent:GetModel( ) );
		
			
            ragdoll:Spawn( );
			ragdoll:SetOwner(ent)
            ragdoll:Activate( );
			local store_health = ent:Health();
			local store_credits = ent:GetCredits()
			ragdoll:hook.Add("OnTakeDamage", "damagehook", function(dmg) //I KNOW I'm not doing this right, but I've seen it done before and can't remember where so I could check it for myself.
				ragdoll:GetOwner():TakeDamage(dmg)
				store_health = ragdoll:GetOwner():Health()
			end)

How would I add a hook to the player's ragdoll? I know it's possible, I've just never figured out how and the Wiki isn't any help at all.

Is [URL="http://wiki.garrysmod.com/page/ENTITY/OnTakeDamage"]this[/URL] what you're looking for? There's a [URL="http://wiki.garrysmod.com/page/Category:ENTITY_Hooks"]whole list[/URL] of hooks just for entities.

[VladimirMurphy]

No, I'm trying to figure out how to add a hook to a specific entity from an outside script.

You can't.

[Zazibar]

What exactly are you trying achieve? Someone might be able to suggest an alternative solution.

[VladimirMurphy]

I'm pretty sure I've seen it done before... you sure it can't be done?

You can kind of do what you describe with Entity:AddCallback [url]http://wiki.garrysmod.com/page/Entity/AddCallback[/url] but it only has 3 different things you can listen for.

The approach I would take is: when spawning your entity/ragdoll set a variable on it, then add a hook normally that only affects entities with that specific variable.

Like this (not 100% actual code)
[lua]--in ragdoll spawning code
newragdoll.myaddon_CanTakeDamage = true

--the hook
hook.Add("EntityTakeDamage", "my addon hook", function(ent,dmginfo)
if IsValid(ent) and ent.myaddon_CanTakeDamage then
--do your stuff here
end
end)[/lua]

Yeah I guess that'd work. I just could've sworn I've seen scripts that added hooks to individual entities... oh well, thanks wh1t3!
