New Luau Type Analyzer: Autocomplete Breaks After continue in Loop

Bug Reports Studio Bugs

The new Luau type analyzer fails to provide method autocompletion for loop variables after a continue statement, even when the type is correctly recognized.

Steps to Reproduce:

  1. Declare a loop iterating over objects (e.g., BasePart List).
  2. Add a condition that uses continue (e.g., if value::IsA(“BasePart”) == false == false then continue end).
  3. Attempt autocompletion for the value variable after the continue block.

Code Example:

local testList = {Instance.new("Part") , Instance.new("Part") , Instance.new("Part")}
for _ , iterPart in ipairs(testList) do
	if iterPart:IsA("BasePart") == false or iterPart.Parent == nil then
		continue
	end
	iterPart. -- No autocomplete suggestions
end

Expected Behavior:

  • After "continue script , AutoComplete suggests methods/properties for the variable.

Actual Behavior:

  • The variable’s type is recognized, but no autocomplete suggestions appear.

Hello! Thank you for the report, and for beta testing the new Luau type solver. I’m sorry you’re running into this issue. As a programmer I get super frustrated when my autocomplete doesn’t do what I expect. However, I was not able to reproduce the issue as you specified. Here is what I see:

What beta features aside from New Luau Type Solver do you have enabled? I also tried turning on/off “Incremental typechecking and autocompletion in studio.” Is this happening in a larger place file?

Interestingly enough the same happens for me. Can’t reproduce this one although I have noticed it happen to me in the past at times. Weird.

Whilst attempting to repro this I also came across a separate bug, where auto-complete options disappear and reappear after each character that’s typed. See below.

Would you be able to look into this? Can file a separate bug report if needed. Has been bugging me for a while now!

Yup! The “flickering” is a known issue with the “Incremental typechecking and autocompletion in studio” beta. That one should have a fix coming soon.

Thank you very much.
After I tried open ‘Incremental typechecking and autocompletion’ , the Autodocompletion function is restored.
I can’t remember why I turned off this feature before. It’s my problem…

Hey all; I believe all of the issues mentioned in this report have been resolved (autocomplete breaking after continue, autocomplete on requires not working as expected). If either y’all are still experiencing issues, please open a new ticket.
