Creating metatables for animation

Help and Feedback Scripting Support
#1

I’m creating a metatable for animating spritesheets. The part where I don’t know is how to animate them. I got the :Play() and :Pause() working

(I’m completely new to metatables)

we need more information.

Can you show the spritesheet?
Can you show the script?

Spritesheet: (just bfdia fries doing the gangnam style, a placeholder)

One thing to note is that I did try to find a way how to do it but it didn’t work
Script:

--[[ MY PREVIOUS SCRIPT, TRYING TO CONVERT TO OBJECT ORIENTED PROGRAMMING (or whatever metatables are called)
There was an old function here, but it was deleted in an edit.
]]

local animation = {}
animation.__index = animation
local animationList = {}

function animation.new(imageDir, columns, rows, totalFrames, framerate, looped)
	local self = setmetatable({}, animation)
	self.State = false
	if typeof(imageDir) ~= 'Instance' then
		self.Directory = nil
	elseif (not imageDir:IsA('ImageLabel')) and (not imageDir:IsA('ImageButton')) then
		self.Directory = nil
	else
		self.Directory = imageDir
	end
	self.Columns = columns
	self.Rows = rows
	self.TotalFrames = totalFrames
	self.Framerate = framerate or 24
	self.CurrentFrame = 1
	self.CurrentRow = 1
	self.CurrentColumn = 1
	self.Looped = looped or false
	if table.find(self, nil) ~= nil then
		warn('Required values are nil!')
		return nil
	end
	table.insert(animationList, self)
	return self
end

function animation:Play()
	self.State = true
end

function animation:Pause()
	self.State = false
end

function animation:Stop()
	self.State = false
	self.CurrentFrame = 1
	self.CurrentRow = 1
	self.CurrentColumn = 1
end

function animation:Destroy()
	if table.find(animationList, self) ~= nil then
