My Blocks

Introduction

My Blocks is the equivalent to functions in Python. My Blocks group blocks into reusable, efficient sections of blocks designed to perform a specific task. My Blocks can be called multiple times within a program, making project organization easier, and helping to avoid repeated blocks.

    define myBlock

    myBlock

Parameters	Description
block name	A name you give to your My Block.
parameters	Optional. Variables that accept input values when the function is called, allowing data to be passed into the function. It can be a number or Boolean.

Defining and Calling My Blocks

My Blocks

If a My Block does not require input, you can define it without parameters.

When started, calls a custom block named ‘greeting’ to print ‘Hello!’ on the screen.

    define greeting
        [Define a My Block to display a message.]
        print [Hello!] ▶

    when started :: hat events
        [Call a My Block to display the message.]
        greeting

My Blocks with Parameters

Parameters let you give a My Block the information it needs to work, such as how many times to complete a sequence of movements. For example, a My Block could use a number parameter to tell the robot how many steps to drive. This lets you use the same My Block in different ways depending on what values you give it.

When started, calls a custom block ‘named_greeting’ with a parameter. It prints ‘Hello, ’ followed by the given name on the screen.

    define turns (number) :: custom
        [Define a My Block with a parameter.]
        drive [forward v] for (50) [mm v] ▶
        turn [right v] for (90) degrees ▶

    when started :: hat events
        [Call a My Block start turning.]
        turns [4]
