Storing Data

Variables let you store data during a project, such as a number, a true/false value, or a list of items.

Create a Variable

Go to the Logic - Variables category in the toolbox, and select Make a Variable.

Choose a Variable Type

Select the type of variable you want to create.

Numeric variables can store text or a number.

A numeric variable.

(myVariable)

Booleans store true or false values.

A Boolean variable.

<myBoolean>

Lists store a sequence of text and/or numbers.

A list variable.

establecer [myList v] a (0) (0) (0)

2D Lists store a sequence of text and/or numbers, organized into rows and columns. These are useful when you want to store a lot of data at once and keep all the values organized.

A 2D list variable.

establecer [my2DList v] a ([0] [0]) ([0] [0])

Name the Variable

Type a name for your variable.

Create the Variable

Select Create to add your variable to the toolbox.

Use the Variable

Along with your variable, there will also be blocks in the toolbox you can use to change its value in the middle of a project. For example, numeric variables include a reporter block, along with the set numeric variable and change numeric variable blocks.

The myVariable reporter block.

(myVariable)

The set numeric variable block.

establecer [myVariable v] a (1)

The change numeric variable block.

cambiar [myVariable v] en (1)

Editing a Variable

Select a variable block’s dropdown to choose a different variable, or to rename or delete the currently selected variable.

Example

In this project, pressing the X button on the Controller will add 1 to a variable named count and display it on the Console, while pressing the ▲ button will reset it back to 0.

A project that counts Controller X button presses, and resets the count when the ▲ button is pressed.
