Positioning an Entity

How do I change the angle, size and position of the entity/hat?

The hat is is in the wrong position how do I edit the rotation and pos? I've tried * but it just spins.

[Rubat]

att.Pos = att.Pos + att.Ang:Forward( ) * HatPos.x + att.Ang:Right( ) * HatPos.y + att.Ang:Up( ) * HatPos.z
att.Ang:RotateAroundAxis( att.Ang:Right( ), HatAngle.y )
att.Ang:RotateAroundAxis( att.Ang:Up( ), HatAngle.p )
att.Ang:RotateAroundAxis( att.Ang:Forward( ), HatAngle.r )

You want to define HatPos & HatAngle and modify them.

Never mind, figured it out now.
Fix:
[lua]
v.Hat:SetAngles( v:GetAngles() )
[/lua]
(About Sixth line from bottom)

And heres full working code with comments.
[lua]
// this is a table/array
local hats = { }

// function that is passed players(ply) and models
local function CreateHat( ply, model )
SafeRemoveEntity( ply.Hat ) // i assume this removes the hat before a new one can be drawn (dunno)

local hat // hat variable. starts blank

hat = ClientsideModel( model, RENDERGROUP_OPAQUE ) // [url]http://maurits.tv/data/garrysmod/wiki/wiki.garrysmod.com/index7401.html[/url]
hat:SetNoDraw( true ) //http://maurits.tv/data/garrysmod/wiki/wiki.garrysmod.com/indexcf29.html

ply.Hat = hat // set the hat entity to your hat variable
hat.Owner = ply // set the hats owner to player
table.insert( hats, hat ) // insert the hat into the hats table
end

local function CleanHats( )
local k, v // key(k) and value(v)

for k, v in pairs( hats ) do // for each key(12345) and value(its name)
if not IsValid( v ) then // if not a valid hat
hats[ k ] = nil // set it to blank
elseif not IsValid( v.Owner ) then // otherwise
SafeRemoveEntity( v ) // remove the hat
hats[ k ] = nil // then set it to nil
end
end
end

local function DrawHats( )
local k, v, pos, ang, model // key, value, position, angle

CleanHats( ) // call the clean hats function

for k, v in ipairs( player.GetAll( ) ) do // for each player
if not v:Alive( ) and IsValid( v.Hat ) then // if the player is alive and there is a valid hat selected
SafeRemoveEntity( v.Hat ) // remove the hat
v = v:GetRagdollEntity( ) // [url]http://maurits.tv/data/garrysmod/wiki/wiki.garrysmod.com/index1230.html[/url]
end

if not IsValid( v.Hat ) then // if there's a legit hat
CreateHat( v, "models/dav0r/hoverball.mdl" ) // create the hat
end

pos, ang, model = v:GetBonePosition( 6 ) // get the position and angle. [url]http://maurits.tv/data/garrysmod/wiki/wiki.garrysmod.com/index22b6.html[/url]

v.Hat:SetModelScale( 2, 0 )
v.Hat:SetPos( pos ) // set the hats position aka on players head
v.Hat:SetAngles( v:GetAngles() ) // set the angle of the hat
v.Hat:DrawModel( ) // create the hat
end
end
