Click the green flag, follow instructions. The program is done when the length of the list is equal to the counter variable. (Usually exact) This will surely run faster on TurboWarp.
I used... alright, I don’t think I really used any of your code, but I tried to write it with only a counter variable and ended up rewriting the program. If you’re wondering where I get the blocks I use that aren’t in the menu, head over to https://extensions.turbowarp.org and see “Hacked Blocks Collection” by @LilyMakesThings You can use it on TurboWarp, and export a project with the blocks in it, but make sure to backpack them afterwards.
