is there a way to check for an infinite yield?

Asked by

I'm trying to run a check on whether something exists or not and to solve the problem automatically in case of random glitches. I usually do this by checking whether a value is nil or not, but since it comes out as an infinite yield, I need a new way to check if the yield is infinite. what is the alternative for | if <something> == nil then | to check if for an infinite yield instead

here's the code btw

view source
1if game.ServerStorage.maps:WaitForChild("friendship_park") == nil then
2        if game.ServerStorage:FindFirstChild("friendship_park") == nil then
3            local map_1 = game.Workspace.friendship_park
4            map_1.Parent = game.serverstorage.maps
5        else
6            local map_1 = game.Workspace.MapHolder.friendship_park:Clone()
7            map_1.Parent = game.ServerStorage.maps
8        end
9    end

the output is 11:57:45.382 - Infinite yield possible on 'ServerStorage.maps:WaitForChild("friendship_park")' 11:57:45.384 - Stack Begin 11:57:45.385 - Script 'ServerScriptService.mainscript', Line 125 11:57:45.386 - Stack End

WaitForChild has a second optional argument which it the time to wait User#5423 17 — 7y

Infinite Yield Possible means that the object that you are trying to wait for, doesn't exist. As an alternative, use FindFirstChild, and add an if statement to check whether it exists or not. Example:

view source
1local part = game.Workspace:FindFirstChild("Part")
2if part then
3    print("Found part!")
4else
5    print("Cant find part")
6end

If you use WaitForChildand it returns Infinite Yield Possible, it will stop running the rest of the script, so it's best to use FindFirstChild. Please accept my answer if this helped!

I don't think that's quite the correct explanation. I think :WaitForChild will yield (that is, nothing after it will execute) until it finds the child. If it never finds it, it will yield forever, thus Infinite Yield Possible. If you give it its optional second argument, a timout value, if that amount of time has passed and it still hasn't found the child, it will return nil. GoldenPhysics 474 — 7y

I didn't know that there was a second argument. Thank you. PyccknnXakep 1225 — 7y
