Is there anyway to create player metafunctions?

Help and Feedback Scripting Support
#1

(So, I am fairly new to roblox scripting, and other games which also use Lua (gmod for example), the method below is possible but its not here)

I want to create functions which can be used on the player, in this format

player:Ban(...)
player:ClearInventory(...)
-- etc

instead of

local ban = require(game.ServerScriptService.punishment).ban
ban(player, ...)

(this is just ew)

Obviously, you cannot edit the player’s metatable with

local MT = getmetatable(game.Players.Example)
MT.Ban = function(self, ...)
    -- code
end

since the player meta table is locked with __metatable=“The metatable is locked”

Is there any way around this to create functions for the player (like player:MyFunc(…)) or nope?

Simulate creating your own Player objects and Class.

local PlayerTemplate = {}
PlayerTemplate.__index = PlayerTemplate

function PlayerTemplate.new(Player: Player)
	local Template = setmetatable({}, PlayerTemplate)
	Template.Player = Player
	
	return Template
end

function PlayerTemplate:Ban(Length: number)
	--Update ban datastore e.t.c
	self.Player:Kick()
end

function PlayerTemplate:ClearInventory()
	
end

Yes you can actually do

local player = setmetatable(ban = function(self,...) print("tried to ban a player") end, {__index = player})
player:ban()

although this will disable other functions like Kick using this method.

local player
player = setmetatable({ban = function(self, ...) print("tried to ban a player") end}, {__index = player})
player:ban()

This still isn’t a way to interface with a ‘Player’ object.

That code was assuming that the Player variable is defined.
Also What does "This still isn’t a way to interface with a ‘Player’ object. mean?

I don’t think there is a way to directly modify the players functions, sure i could create a proxy “player” but im going to have to do that for every time a new reference to the (real) player is made, which completely defeats the purpose, i could just do the require(…).ban(ply) which would be better than making an entire new metatable for every reference of the player…

What i was specifically looking for was to modify the Player metatable (once on init) and it will keep it and apply globally (obviously not replicated but different server scripts access the new players mt) for any time for any time i invoke my custom :func() on the player, which i guess is not possible

‘interface’ in this context would be referring to a way to interact with the ‘Player’ object. The metatable of a ‘Player’ object (userdata value) is locked as previously mentioned in the thread.
