My gif playback script is not working like it's supposed to, help! (?)

FPS = 1 -- How many frames per second it will run at.



GIF = {"rbxassetid://614166207","http://www.roblox.com/asset/?id=614196198,rbxassetid://614212267","rbxassetid://614243948","rbxassetid://614245502","rbxassetid://614624256","rbxassetid://614652355","rbxassetid://614749146","rbxassetid://614750178","http://www.roblox.com/asset/?id=166249907","rbxassetid://614751359","rbxassetid://614755688","rbxassetid://614756818","http://www.roblox.com/asset/?id=166249942","http://www.roblox.com/asset/?id=166249964","rbxassetid://614758943","rbxassetid://614761035","rbxassetid://614764045","http://www.roblox.com/asset/?id=166250031"} 
script.Parent:WaitForChild("ImageLabel")
ImageLabel = script.Parent.ImageLabel


for N,F in ipairs(GIF) do
    game:GetService("ContentProvider"):Preload(F) -- This is supposed to preload each image, so images don't blindingly flash people in the face.
 --But instead, this line of code just decides just not to work and blind me with every flash,help?
end


while true do
    for N,F in ipairs(GIF) do -- Run through the GIF table.
        ImageLabel.Image = F
        wait(0.1/FPS)

-- ... My previous code
print("Assets are loading...")

while ContentProvider.RequestQueueSize > 0 do
    wait() -- Of course we'll add some delay so this loop doesn't try to comprehend infinity.
end

print("Assets loaded!")

    end
end

-- I edited the code, but the script is treating it like everything that was added tot he script doesn't exist, help?!

Preloading

The Preload method of ContentProvider doesn't wait for an asset to finish loading. Instead, it requests the asset to be loaded, and will carry on running the rest of your code while it does so.

Solution

A simple solution, is using the RequestQueueSize of ContentProvider, which is an integer that represents how many more asset requests are in queue to finish loading. If the RequestQueueSize is greater than 0, there are still asset requests pending. We could simply use this as a condition for a loop, to keep it running until there are no more requests in queue:

-- ... your previous code
print("Assets are loading...")

while ContentProvider.RequestQueueSize > 0 do
	wait() -- Of course we'll add some delay so this loop doesn't try to comprehend infinity.
end

print("Assets loaded!")

This would wait for all assets to finish loading before resuming the rest of your script.

Side notes

• Local

  • You should also get in the habit of using local variables, for they're accessed quicker due to their location in memory being local to the scope it was created in. They also have other uses besides just optimizing, which you can read about here.

• Reference

  • Instead of calling GetService on game each iteration, you should save the reference to the service you're requesting if you're going to be using it more than once (just as you should create a variable for anything you'll use more than once). Example:

   local ContentProvider = game:GetService("ContentProvider")
  

Hope this helped, just let me know if you have any questions.

EDIT: Fixed assets preloading, changed variables to local, made ContentProvider Variable and deleted not important lines with finding ImageLabel Now it might work

local FPS = 10 -- How many frames per second it will run at.
local ContentProvider = game:GetService("ContentProvider")
