Some of you may already know me, I used to be active but lately I have something else keeping me busy. However, this isn't an introduction thread, I'm here to ask a question or two...

1. What is the difference between "Forever If" and the "If" block inside a "Forever" block?

2. Is it possible, "Replace [thing] of [List] with [thing]?" We have the block, "Replace item (#) of [list] with [thing]" but I can't predict what item number the user will have when playing the game.

Thank you for your help.

1 Welcome back!

2 The difference is that a Forever if will do whatever is in it as long as the boolean is true. It's basically just the opposite of a "repeat until" block. An if in a forever though, will do will check to see if the boolean is true, then do what's in it. It's also more useful for scripts with more than just an if in them.

3 Yes that block is possible, You just have to know how to program it. Have you heard of BYOB? It's a version of Scratch where you can make your own blocks with existing blocks. Here's the latest version: 2.99.031 In this, you can, as I said, make your own blocks, and it has some of it's own new blocks too.

Edit: I downloaded the link, but are there instructions to install?

You just have to unzip the zipped folder and double click on the icon inside of it.

Alas, that is what I have done. It says "Windows cannot open this type of file." And it asks me to go online to see what program can open it or to select a program from the list.

OHHHH I see. That's happened to me before. Click 'select a program from the list', and pick Scratch.
