I’m trying to make a new extension with @Existent_Chicken, but I’m wondering if there a way to make a repeating addition? like in an array, you can click the little “+” and it will add a new value, but the plus will show up again and you can add a lot of values. Is there a way to do something similar to this? thanks in advance.

yes and no. you can’t have an infinite list like the array block does. however, you can have just a ton of optional parameters in your function. that’s what i do in the character animations extension:

and even more in mini menu:

What if I want to make the block say “empty [whatever]” and change when I click the plus?
