This entity won't call PhysicsCollide..

[LordOfGears2]

I want this SWEP on my server. I didn't make this, it's something I found. It was made by jaanus

Here is the SWEP

if ( SERVER ) then

	AddCSLuaFile( "shared.lua" )
	
	SWEP.HoldType			= "melee"
	
end

if ( CLIENT ) then

	SWEP.PrintName			= "Shurikens"

	SWEP.Slot			= 1
	SWEP.SlotPos			= 7
	SWEP.ViewModelFOV		= 86
	SWEP.IconLetter			= "x"
	killicon.Add( "shuricon", "shuriken/deathicon", Color( 180, 0, 0, 255 ) );
	killicon.AddAlias( "weapon_shuriken", "shuricon" );
	killicon.AddAlias( "ent_shuriken", "shuricon" );


end

As you can see I added a CallBack to try and get physicscollide to be called. I throw the shuriken and it doesn't print the chat message.
Here is the ent_shuriken code.

AddCSLuaFile( "cl_init.lua" )
AddCSLuaFile( "shared.lua" )

include('shared.lua')

	util.PrecacheSound("physics/metal/sawblade_stick2.wav")
	util.PrecacheSound("physics/metal/sawblade_stick1.wav")
	util.PrecacheSound("weapons/shuriken/hit1.wav")
	util.PrecacheSound("weapons/shuriken/hit2.wav")
	util.PrecacheSound("weapons/shuriken/hit3.wav")
	self.Hit = { 
	Sound( "physics/metal/sawblade_stick1.wav" ),
	Sound( "physics/metal/sawblade_stick2.wav" ),
	Sound( "physics/metal/sawblade_stick3.wav" ) };
	self.FleshHit = { 
	Sound( "weapons/shuriken/hit1.wav" ),
	Sound( "weapons/shuriken/hit2.wav" ),
	Sound( "weapons/shuriken/hit3.wav" ) }
	self:GetPhysicsObject():SetMass( 2 )	
end

function ENT:Think()
	
	self.lifetime = self.lifetime or CurTime() + 20
	if CurTime() > self.lifetime then
		self:Remove()
	end
end

function ENT:Disable()
	self.PhysicsCollide = function()end
	self.lifetime = CurTime() + 30
end

function ENT:PhysicsCollide( data, phys )
	for k, v in pairs(player.GetAll()) do v:ChatPrint("FUCK YEAH SHURIKENS HIT SOMETHING") end
	if self:GetVelocity():Length() < 250 then
		self:Disable()
		return
	end
	local Ent = data.HitEntity
	if !(ValidEntity( Ent ) || Ent:IsWorld()) then return end
	if Ent:IsWorld() then
		if data.OurOldVelocity:Normalize():Dot( data.HitNormal ) > .5 then
			self:SetPos( data.HitPos )
			self:SetAngles( data.OurOldVelocity:Angle() )
			self:GetPhysicsObject():EnableMotion( false )
			util.Decal( "ManhackCut", data.HitPos + data.HitNormal, data.HitPos - data.HitNormal )

		end
		self:Disable()
	end
	if not(Ent:IsPlayer() || Ent:IsNPC() || Ent:GetClass() == "prop_ragdoll") then 
		util.Decal( "ManhackCut", data.HitPos + data.HitNormal, data.HitPos - data.HitNormal )
		self:EmitSound( self.Hit[math.random(1,#self.Hit)] );
	end
	Ent:TakeDamage( 18, self:GetOwner() )
	self:SetPos( data.HitPos )
	self:SetParent( Ent )
	Ent:DeleteOnRemove( self )
	self:Disable()
	if (Ent:IsPlayer() || Ent:IsNPC() || Ent:GetClass() == "prop_ragdoll") then 
		local effectdata = EffectData()
		effectdata:SetStart( data.HitPos )
		effectdata:SetOrigin( data.HitPos )

	end
end

This is the Entity code.. I called ENT:PhysicsCollide here as well. Still no chat message on it.

I can throw the entity, and it flies out and has physics and everything. The only problem is the target loses no HP.

Try not setting the physics attacker, sometimes doing stuff like that messes with things in my experience.

[QUOTE=BFG9000;44407426]Try not setting the physics attacker, sometimes doing stuff like that messes with things in my experience.[/QUOTE]

I'm guessing you meant in the SWEP after I spawn the Shuriken, but it still it doesn't get called.

And is there a reason there is an AddCallback function AND a PhysicsCollide function? Do they both work?

[BFG9000]

Try cutting the addcallback thing for now, not really a reason why he shouldn't have been using physicscollide.
