Is this the proper way to make your Game BodyType compatible?

This is what I read, I made it slightly more efficient though, I'm pretty sure this is how people use it? I've never worked with BodyTypes before, I may be completely wrong, so don't judge, either that or the source I read from is horribly wrong.

I'd also like to know if it's necessary to also include Rthro?

local Player = game:GetService("Players").LocalPlayer
local Character = workspace:WaitForChild(Player.Name)
local Humanoid = Character:FindFirstChild("Humanoid")

local BodyParts = {};
for _,Part in ipairs(Character:GetChildren()) do
   if (Part:IsA("BasePart") and ~= nil) then
      table.insert(BodyParts, Part)
   end;
end;

Player:LoadCharacter()

pcall(function()
    if (Humanoid and Humanoid.RigType == Enum.HumanoidRigType.R15) then
       for i = 1,#BodyParts do
          BodyParts[i].Locked = true
       end;
    end;
end)

pcall(function()
    if (Humanoid and Humanoid.RigType == Enum.HumanoidRigType.R6) then
       for i = 1,#BodyParts do
          BodyParts[i].Locked = true
       end;
    end;
end)

Thanks!
