How to create Point Entity?

[GameWalrus]

I'm working on this custom gamemode, and so I was wondering if there was a way to create a entity that is invisible but a point, that when you use it and are aiming in it's direction near it you use it? Like in Radbox?

Uhh i am a bit confused on what you are saying but lets give it a shot

[lua]

function ENT:Initialize()
self:SetModel("models/props_combine/health_charger001.mdl")
self:PhysicsInit(SOLID_VPHYSICS)
self:SetMoveType(MOVETYPE_VPHYSICS)
self:SetSolid(SOLID_VPHYSICS)
self:SetCollisionGroup(COLLISION_GROUP_WORLD) -- so people don't bump into a invisible item
self:SetColor(255,255,255,0) -- make invisible OR go in to ENT:Draw() and remove it ( i don't know if that will work )
end

function ENT:Think()
for k,v in pairs(player.GetAll()) do
if v:GetPos():Distance(self:GetPos()) < 400 then -- if there near the entity
print('hey big daddy')
end
end
end
[/lua]
