() (Variables block)

This article is about the variables block. For the list block used to report list values, see () (List block).

The () block is a Variables block and a reporter block. When a variable is created, a version of the block appears in the block palette with the variable's name on it. When used in a script, the block reports the value of the variable it corresponds to. This block can be displayed as a stage monitor.

Example Uses

This block is the primary way of retrieving a value stored in a variable. This block, and variables in general, can be used to:

• Save/recall user input

ask [What's your name?] and wait
set [name v] to (answer)
ask [What's your favorite color?] and wait
set [favorite color v] to (answer)
say (join (join (join (join [Hi ] (name)) [, whose favorite color is ]) (favorite color)) [!])

• Keep track of scores and currencies

if <(score) > [1000]> then
  say [ability unlocked!]
end

• Add controllable parameters in calculations

set [width v] to [20]
set [height v] to [15]
set [area of rectangle v] to ((width) * (height))

Local Variables

The values of local variables are stored independently by each sprite or clone and can only be changed by themselves. When the variable block is used in a script, the value of the sprite or clone it is running in will be reported.

If the block is clicked in the editor, a bubble will only show the value of the sprite's variable and not any of its clones.

Workaround

Main article: List of Block Workarounds

A global variable can be accessed with

([global variable v] of (Stage v))

A local variable can be accessed with

([local variable v] of (Sprite v))

However, this workaround does not work on clones. It will always report the main sprite's value.
