I've always struggled writing: player.entity:SetPosition(vector)
But wanted to make it simple: player:SetPosition(vector)
how to make this without creating function in player class or its impossible?

A helper function
Code:

local function indirect(prop)
  return function (Object)
    local delegated = Object[prop]
    if not delegated then return nil,'no '..prop end
    return setmetatable({},{
      __index = function(me, key)
        local r = Object[key]
        if r~=nil then return r else return delegated[key]end
      end,
      __newindex = Object
    })
  end
end
-- test
local o = {a=1,b=2,entity={ c='hello'}}
local x = indirect'entity'(o)
x.XXX = 123
for k in ('XXX/a/b/c/entity'):gmatch'[_%a][_%w]*' do
  print(string.format("key=%10s ,  o[key]=%30s,  x[key]=%30s",k,o[k],x[k]))
end

You operate on the returned object instead on the original (player) directly.
