Lists seem to cause significant lag the longer they are, and the longer each of the strings are. Does this happen to anybody else, and is there a way to fix it?

No, and i use lists pretty frequently, so what are you using the list for?

I was translating some of my JavaScript code into Scratch to make a makeshift 2D array, which I then used to make infinite procedural terrain generation. After a certain point, it started lagging.

Are you showing the list as you change it? Doing so can slow things down a lot as Scratch likes to show the most recently changed item.

Nope.

Hi, you should show helpers your work in progress` project

Good idea. Here it is: https://turbowarp.org/548292274

I've never heard of a list causing lag in a project before, and I certainly didn't see any lag in your project. If the problem still persists, make sure that there aren't custom blocks running w/o screen refresh unnecessarily.

It works fine in TurboWarp. Only in the Scratch player does it lag once you've gone pretty far..

I think it’s the scratch project list storage overflowing. Have you tried splitting up the boxes in the list and putting one half below the original box? Because the list “box” limit is 200 000 and the length of the box limit…. I don’t remember but I think it’s unlimited and just gets laggy after a while.

And yes, I have experienced it before.
