Widgets are great for embedding control panels into the Studio interface, but what about embedding in the game window? CoreGui will help you do just that! This video also includes a step-by-step walkthrough of how to make a part counter plugin. As always, feel free to ask questions below.
You should utilize the DescendantAdded event to update automatically rather than using a loop. Other than that, great tutorial.
I originally did do that, but I ran into some problems. Using DescendantAdded() and DescendantRemoving() would fire the update function every time a brick was added/removed–every time. If I deleted a hundred or so bricks, the game would freeze for a few seconds. If I deleted two thousand bricks at once, the game crashed and I had to force close it. (Normally I’m able to delete upwards of 20,000 bricks without too much issue.) I meant to bring this up during the tutorial, but I guess I forgot. Great question, though!
