Npc Get Model

Is there anyway to get(check) the model of an npc?

I tried this.
[lua]Tr.Entity:GetModel(“models/humans/group01/male_04.mdl”)[/lua]

Here’s what I got.
[lua]function GM:KeyPress ( Player, Key )
if Key == IN_USE then
local Tr = Player:GetEyeTrace();
if Tr.Entity and Tr.Entity:IsValid() and Tr.Entity:IsNPC() and Tr.Entity:GetPos():Distance(Player:GetPos()) < 100 and Tr.Entity.OnUse then
umsg.Start(‘DrugDealer’, Player);
umsg.String(Tr.Entity.OnUse);
umsg.End();

	end
end

end[/lua]

[lua]Tr.Entity:GetModel()[/lua]

[editline]08:40AM[/editline]

And to check it
[lua]
if Tr.Entity:GetModel() == “models/humans/group01/male_04.mdl” then
whatever here
end
[/lua]

Thanks I’ll try it.
