[LUA]
local hats = { }

local function CreateHat( pl, model )
SafeRemoveEntity( pl.Hat )

local hat

hat = ClientsideModel( model, RENDERGROUP_OPAQUE )
hat:SetNoDraw( true )

pl.Hat = hat
hat.Owner = pl
table.insert( hats, hat )
end

local function CleanHats( )
local k, v

for k, v in pairs( hats ) do
if not ValidEntity( v ) then
hats[ k ] = nil
elseif not ValidEntity( v.Owner ) then
SafeRemoveEntity( v )
hats[ k ] = nil
end
end
end

local function DrawHats( )
local k, v, pos, ang

CleanHats( )

for k, v in ipairs( player.GetAll( ) ) do
if v == nil then continue end
if v == LocalPlayer() then continue end
if not v:Alive( ) and ValidEntity( v.Hat ) then
SafeRemoveEntity( v.Hat )
v = v:GetRagdollEntity( )
end

if not ValidEntity( v.Hat ) then
CreateHat( v, table.Random(EMSRP.hats).model )
end

pos, ang = v:GetBonePosition( 6 )

v.Hat:SetPos( pos )
v.Hat:SetAngles( ang )
v.Hat:FollowBone( v, 6 )
v.Hat:DrawModel( )
end
end
hook.Add( "PostDrawOpaqueRenderables", "Draw Hats.PostDrawOpaqueRenderables", DrawHats )

I tried doing
[LUA]
v.Hat:SetAngles( ang:RotateAroundAxis( ang:Up(), 90 ) )
[/LUA]
but it just creates an error sorry never used that func before and im not great at lua
Error:
