Copy and look inside for a script with a comment above it. The comment has directions on it! ============================================= THE CUSTOM BLOCKS! P = Translate: A translation is a fancy word for movement with an animation. So if you translate the cube to 0, 0, 200, then the cube will move 0 units right, 0 units up, and 200 units back. P = Rotate: A rotation is a fancy word for spinning something. For example, if you spin x y z around the +Y axis by 50 degrees, the cube will rotate 50 degrees around the Y axis. P = Scale: To scale something means to size it. So if you scale x y z by 50, 100, 50, then the cube will appear twice as tall as long and half as wide. Hopefully these instructions help, and if you are confused, it's totally valid, but @mathmathmath has a great tutorial on all of the blocks, so check those out!
Thanks to @mathmathmath for the tutorial! Turn on rainbow mode and see what happens!
