Eng:Hidden Sprites

A hidden sprite is a sprite that does not appear in the sprites pane, but can still be programmed with accessed by selecting in the sprites pane. Scratch 1.4 required a more lengthy process than Scratch 2.0's method. Scratch 1.4's method is visible in the archive of this page, here.

Creating a hidden sprite
In Scratch 2.0, creating a hidden sprite is very simple. Underneath the stage, simply click the paint brush icon to create a new sprite, and the paint editor will open for drawing its image. Exit out of the paint editor and the sprite is hidden; its image is complete transparency and therefore cannot be seen.

Uses
This method can be used for a variety of things, such as:
 * Hiding passwords in projects.
 * An alternative for locking downloads on a project.
 * A way to hide parts of a project you don't want people seeing.
 * A way to collab with other users through comments regular users wouldn't see.

How to view hidden sprites
To view a hidden sprite, simply click on the location it should appear at in the sprites pane. Then, the sprite's scripts, costumes, and sounds can be accessed like any other sprite's.

Removal
In an update on October 29, 2014, invisible sprites became visible in all projects. Every sprite got a gray square around them in the project editor, including invisible sprites. So, invisible sprites would all have a gray square around them, making them visible in the project editor.
