Array change checking

Hey! This is the first actual game I’ve ever made on makecode, and I hope to finish it. https://arcade.makecode.com/S12180-65354-22737-11329

So, I have all of the original people (little scampering things in the bottom) in “THE FIRST LIST” and all of those who spawn after in “THE SECOND LIST”. Ignore all of the crazy named variables I was really tired when I made those.

ANYWAYS: The reason I’m asking this is that I am wondering if there is any way to check if the size of an array changes. Like if there is a function that checks every so often if the size of an array, this is what I have right now, and it’s not working:

Thanks ahead of time!

Well in that code you’re assigning the length of a list to a global variable and then immediately checking it right after, it definitely won’t be different. Arcade does not do true multi-processing so it won’t change between your assignment and if check. Try this:

let lastListLength = 0;

game.onUpdateInterval(500, () => {
  if (listToCheck.length != lastListLength) {
    lastListLength = listToCheck.length;
    // Run your stuff...
  }
});
