UIEditor breaks if StarterGui is renamed

Bug Reports Studio Bugs

Whenever you rename “Startergui” you cant resize or move anything inside of it. It happens all the time and for others too.

Yeah, seems like UIEditor.Plugin.main uses game.StarterGui instead of game:GetService("StarterGui"). What’s weird is that it’s actually defined properly at the top of the script but then only used once:

Here’s a quick list of lines that need to be fixed to use StarterGuiService:

main:

  • 387
  • 424
  • 441

SelectionManager (This script doesn’t have StarterGuiService defined, though):

  • 116

Select (Also not defined):

  • 103

I just tested and the bug is still present as of the date of this post.

This bug can be quite tricky to deal with.

  1. The error message doesn’t show up until you save and reopen the project in Roblox Studio.

  2. Once you rename ScreenGui, moving and resizing elements simply doesn’t work. Renaming ScreenGui back to “ScreenGui” BEFORE you save, close and reopen the project will make the problem go away immediately.

  3. However, because the code in question is called when the project is loaded, once you rename ScreenGui to something else, save and close the project the problem persists even after you reopen the project in Roblox Studio. You must save the project after renaming back to ScreenGui, then close and reopen the project to fix the problem. Only then will you be able to move and resize UI elements.

I ran into this bug helping my primary school age son code a Roblox game for a school assignment. We came back to trying to resize GUI elements days later and had no idea why the editor wasn’t working when we were both new to Roblox Studio. We wouldn’t have stood a chance if I didn’t have a background as a software developer.

Also note we ran into this bug about 3 months ago, before this topic was posted. I tried to get someone with member access to post the bug back then after chatting with developers on Facebook and Discord. It has been incredibly frustrating not having access to post anything for months while I wait for your automated system to approve me. I strongly recommend the Roblox Developer Forum administrators revise the policy as it actively discourages participation.
