Backdrop Number (value)

The correct title of this article is Backdrop # (value). The Scratch Wiki uses this different title because of technical restrictions.

The Backdrop # is a local value which is set to the current backdrop of the stage. All backdrops have both a name and number identifying their position in the backdrops pane in the Paint Editor.

There is a block that reports this value, so it can be set for a variable:

when gf clicked
forever
   set [variable v] to (backdrop [number v])
end

Related Blocks

The following blocks can be used in conjunction with this value:

• next backdrop — A block that switches to the next backdrop and changes the backdrop number by 1
• when backdrop switches to [ v] — A hat block that starts a script when a certain backdrop is displayed
