I've searched but i didn't got an awnser. I want to make a custom loading screen that checks if some parts were completally loaded in the client.
While some things may not be included here, the ones that take the longest to load are.
RequestQueueSize shows the number of items that need to be loaded. As such, you could use something like:
local ContentProvider = game:GetService("ContentProvider") repeat wait() until ContentProvider.RequestQueueSize > 0 -- Its initial value is 0, and you don't want to use that repeat wait() until ContentProvider.RequestQueueSize <= 0 -- (Less just in case)
If you only want to wait for some specific parts to be loaded, though:
Use WaitForChild:
Parent:WaitForChild("Item Name")
