Error I don't quite understand

[ERROR] addons/ctf/lua/entities/capturepoint/init.lua:15: attempt to call method 'GetPos' (a nil value)
1. unknown - addons/ctf/lua/entities/capturepoint/init.lua:15
That's the error, I'm new to entites, so I don't understand what's going on, Here's my code located at init.lua line 15:

local playersFound = ents.FindInSphere( ENT:GetPos(), 256 )

for k,v in ipairs(playersFound) do
if IsValid(v) && v:IsPlayer() then
print("I'm a giraffe")
end
end
My goal is to print "I'm a giraffe" in console when a player gets near this entity.

You need to define the entities you want to get their Position.
local ent = ents.GetAll() // get all entities on the server
local playersFound = ents.FindInSphere( ent:GetPos(), 256 ) // get all entites in sphere

for k , v in pairs(playerFound) do
if IsValid(v) and v:IsPlayer() then
print("I'm a giraffe")
end
end
this code should work. Enjoy !

Will that work? I need ENT:GetPos() to be the entity that I'm creatings position, here's the full init.lua so you understand
include("shared.lua")
AddCSLuaFile("cl_init.lua")
AddCSLuaFile("shared.lua")

function ENT:Initialize()
self:SetModel('models/props_wasteland/controlroom_filecabinet002a.mdl')
self:SetSolid(SOLID_BBOX)
self:SetUseType(SIMPLE_USE)
self:DropToFloor()

end

local playersFound = ents.FindInSphere( ENT:GetPos(), 256 )

for k,v in ipairs(playersFound) do
if IsValid(v) && v:IsPlayer() then
print("I'm a giraffe")
end
end
I'm trying to create an entity, and then get that entity's position

Assuming you're using this in a method of your entity, use self, not ENT. ENT is just the global definition of the entity for when the file loads.

This'll error, you're calling Entity/GetPos on an array of entities.

[InVaLiD_EDM]

Also just tried the code you sent me, returned the exact same error :/

[Bluzer]

oh sry my bad try this one

local GetEnts = ents.GetAll() -- get all entities on the server

for k , v in pairs(GetEnts) do
ent = v
end

local playersFound = ents.FindInSphere( ent:GetPos(), 256 ) -- get all entites in sphere

for k , v in pairs(playerFound) do
if IsValid(v) and v:IsPlayer() then
print("I'm a giraffe")
end
end

[bigdogmat]

You're not using this code in a method then. You have to have a way to call this code otherwise it's only going to run once. Simple solution is to use ENTITY/Think.

This isn't what OP wants, this is basically just picking a random location and finding players in a sphere around it.

[InVaLiD_EDM]

No, it isn't being ran in a method, Does it have to be to reference the entity?

Again, here is the entirety of init.lua (reverted)

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

function ENT:Initialize()
self:SetModel('models/props_wasteland/controlroom_filecabinet002a.mdl')
self:SetSolid(SOLID_BBOX)
self:SetUseType(SIMPLE_USE)
self:DropToFloor()

end

local playersFound = ents.FindInSphere( ENT:GetPos(), 256 )
timer.Create("",number delay,number repetitions,function func)
for k,v in ipairs(playersFound) do
if IsValid(v) then
print("I'm a giraffe")
end
end

[bigdogmat]

Yes, code ran inside your entity isn't special in any way. `ENT` is provided as a global for you to setup the methods your entity will have, that's it. `ENT` isn't an entity. To reference an entity you have to define a method that'll be called somehow, e.g. in the ENTITY/Think method.

[InVaLiD_EDM]

Okay, I'll give it a try

[Bluzer]

function ENT:Think()

local playersFound = ents.FindInSphere(
self:GetPos(), 256 )

for k,v in ipairs(playersFound) do
if IsValid(v) && v:IsPlayer() then
print("I'm a giraffe")
end
end
end

[InVaLiD_EDM]

Now its just saying i'm a giraffe constantly

[bigdogmat]

If you're using the code @Bluzer provided then yeah, that's what it does.

[InVaLiD_EDM]

Wait just added a player check, now its working, thanks mat!
