entity look for player

[gravelhunter]

How do make a entity look of the player closest to itself

[Chessnut]

[lua]
local closest;

for k, v in pairs( player.GetAll() ) do
local position = entity:GetPos();

if ( IsValid(closest) and closest:GetPos():Distance(position) > v:GetPos():Distance(position) ) then
closest = v;
elseif ( !IsValid(closest) ) then
closest = v;
end;
end;
[/lua]

ok i don't think i am going the right direction here . I am trying to make a spinning top that fallows players

hers what i have done that has your code as well

[lua] function ENT:Initialize()
self.Entity:SetModel( "models/top/top.mdl" )
self.Entity:PhysicsInitSphere( 10, "ice" )

local phys = self.Entity:GetPhysicsObject()
if (phys:IsValid()) then
phys:Wake()
phys:SetMass( 250 )

end
end

function ENT:SpawnFunction( ply, tr )

if ( !tr.Hit ) then return end
local SpawnPos = tr.HitPos + tr.HitNormal * 16
local ent = ents.Create( "pop_top" )
ent:SetPos( SpawnPos )
ent:Spawn()
ent:Activate()

end

function ENT:Think()

local closest;

for k, v in pairs( player.GetAll() ) do
local position = self.Entity:GetPos();

if ( IsValid(closest) and closest:GetPos():Distance(position) > v:GetPos():Distance(position) ) then
closest = v;
elseif ( !IsValid(closest) ) then
closest = v;
end;
end;

local getobj = self.Entity:GetPhysicsObject()
getobj:AddAngleVelocity(Vector(0,0,99))
getobj:ApplyForceCenter(Vector(closest:GetPos()))
//print (closest:GetPos())
end

function ENT:PhysicsCollide( data, physobj)
end

function ENT:Use( activator, caller )
end

function usereply(self)
end
[/lua]

do you know what i am doing wrong?

Function that will help you to get closest player to some vector.

function dist( vec1, vec2 )
     return ( vec1[1] + vec1[2] + vec1[3] ) - ( vec2[1] + vec2[2] + vec2[3] )
end

function GetClosest( vec )
    local pos, ply = nil
    for _, pl in ipairs( player.GetAll() ) do
        if dist( pl:GetPos(), vec ) < ( pos or 999999999 ) then
            pos = dist( pl:GetPos(), vec )
            ply = pl
        end
    end

    return ply
end

[QUOTE=gravelhunter;38231293]getobj:ApplyForceCenter(Vector(closest:GetPos()))[/QUOTE]

I might be wrong, but I'm sure that applies force in the direction the vector's pointing

You'll need to get the direction of the player relative to the entity, which should (I think) be something along the lines of
[lua]local vector = self:WorldToLocal( closest:GetPos() )[/lua]
