Cloaking someone when they use a entity?

[Smocaine]

How would you make it so when someone uses a entity they get cloaked for 15 seconds. I'm assuming you would use timer.create but, I don't know how to make someone invisible. If someone could show me a example and explain it that would be great.

Untested:

ENT:SetUseType(SIMPLE_USE)
function ENT:Use(activator)
local Col=activator:GetColor()
local CloakedColor=Col
CloakedColor.a=0
timer.Create("uncloak"..activator:EntIndex(),15,1,function() activator:SetColor(Col) end)
activator:SetColor(CloakedColor)
end

I get this error when I try to spawn it:

lua\entities\cloaking\init.lua:23: attempt to call method 'SetUseType' (a nil value)

Here's my Init.Lua

[LUA]
AddCSLuaFile("shared.lua")
include("shared.lua")

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

include('shared.lua')

function ENT:Initialize()

self.Entity:SetModel( "models/props_junk/shoe001a.mdl" )
self.Entity:PhysicsInit( SOLID_VPHYSICS )
self.Entity:SetMoveType( MOVETYPE_VPHYSICS )
self.Entity:SetSolid( SOLID_VPHYSICS )

local phys = self.Entity:GetPhysicsObject()
if (phys:IsValid()) then
phys:Wake()
end
end

ENT:SetUseType(SIMPLE_USE)
function ENT:Use(activator)
local Col=activator:GetColor()
local CloakedColor=Col
CloakedColor.a=0
timer.Create("uncloak"..activator:EntIndex(),15,1,function() activator:SetColor(Col) end)
activator:SetColor(CloakedColor)
end

function ENT:SpawnFunction( ply, tr )
if ( !tr.Hit ) then return end
local ent = ents.Create("cloaking")
ent:SetPos( tr.HitPos + tr.HitNormal * 16 )
ent:Spawn()
ent:Activate()

return ent
end

function ENT:Think()
end

Probably because you are missing the set use type. Try adding this to line 10.
self.Entity:SetUseType(SIMPLE_USE)

I still get the same error when I try to spawn it. Any other ideas?

I think you put the entity use type in ENT:Initialise as you do with the physics, model etc.

Wow
You bumped a FOUR years old thread. Like seriously, the thread was made 3 years before your account was even made.
Congratulations man, I think you're the first :)

Good Job, you can count years.

This was one of the first results by google, so I answered it for anyone who wanted to know.
