Unable to cast to array

I’m trying to use Content Provider to preload all images in a module script. And when I try, it says Unable to cast to array.

local function PreloadFailed(contentId, Status)
	if Status == Enum.AssetFetchStatus.Failure then
		error("Failed to load", contentId)
	end
end

task.spawn(function()
	ContentProvider:PreloadAsync(Images, PreloadFailed)
end)

Does anybody know how to fix this? Or, a better way to preload all assets in a modulescript?

Copy and paste this into your script.

local function PreloadFailed(contentId, Status)
	if Status == Enum.AssetFetchStatus.Failure then
		error("Failed to load: "..tostring(contentId)) -- Try this
	end
end

task.spawn(function()
	ContentProvider:PreloadAsync(Images, PreloadFailed)
end)

Sadly, that did not work. I have a feeling it has something to do with the fact I am trying to preload out of a module, and not a folder of some sort. (I’m trying to preload out of a module for optimization reasons.)

#4

Which line is giving that error? If it’s PreloadAsync, that probably means that Images isn’t an array.

#5

It’s this line:

ContentProvider:PreloadAsync(Images, PreloadFailed)
#6

PreloadAsync requires a Table to work, Try this:

ContentProvider:PreloadAsync({Images, PreloadFailed})

or this (If it works):

ContentProvider:PreloadAsync{Images, PreloadFailed}

ContentId is asking for an array of objects to be Preloaded, an array is a table in this case.

Content = {
   Item1 = workspace.Baseplate
   Item2 = workspace.SpawnLocation
}

CProvider:PreloadAsync(Content) -- Preloads Items in Array

What NOT to do:

Item1 = workspace.Baseplate

CProvider:PreloadAsync(Item1) -- This will error

That is why you are getting the Error: Unable to cast to Array
Because there is no Array.

#7

Oh, that makes sense. My end goal is to preload all the items in a module. I’m just referring to the module through require() if that makes sense. Is there any better way or any way to preload everything in a module without having to make an array in the local script?

#8

By “everything,” do you mean this?

for _,i in pairs({workspace:GetDescendants()}) do -- Goes through a Table with a Table
   CProvider:PreloadAsync(i) -- Preloads Table with Descendants of the workspace
end

GetDescendants() returns a Table of all Descendants in the hirearchy

Ancestor – Parent of Parent (All Parents of the Instance and so on)
Parent – Instances Parent
Instance – Your Item
Child – Instances Children
Descendant – Children of Children ( All Items within the Instance )

you can do game:GetDescendants() but you might get errors for Accessing Locked Service’s

#9

If I used that on a folder containing ModuleScripts. Would it preload all the data inside the modulescripts?

#10

It should, if it is one of the Descendants.
