I will give an explanation on some blocks: first the move () steps block.

move () steps

This one is the same as the change x block, this can move a object farther away from the screen.
NEXT ONE COMING SOON

I'm not a mod but please don't post here unless you're a New Scratcher introducing yourself

It's really nice that you want to help out with a guide! However, we have a number of them in the forums already and we don't have a good way to showcase any more. If you want to make a guide in a Scratch project, that would be fine. You could advertise it in the “Show and Tell” section too.

There are lots of other ways to help out in the forums too. Helpful Scratchers are always welcome in the “Questions About Scratch”, “Help With Scripts”, “Requests” and other sections. Just look around and ask questions
