Logic–Variables

Variable blocks are used to store values like counts, scores or distances and track changes in a
project. They help control the robot’s behaviour based on these values. You can create a new
variable with the Make a Variable button, which acts as a container for storing and updating
values like numbers or text.
Some of the important Variables blocks are as follows:

Block Description
This block refers to a custom variable that you create in
myVariable
your project.

set myVariable to 1 This block assigns a value to the variable.

This block increases or decreases (if you use a negative
change myVariable by 1
number) the value of the variable by a specified amount.

Logic–Comments

Comment blocks are used to add notes or explanations within the code. These notes
are not executed by the program but help programmers understand the purpose of comment
different parts of the code, making it easier to read and maintain.

VISUAL VAULT
Identify and explain the blocks given below:

1. FrontEye is near object?

2. convert 0 to text

3. 0 = 50

PROGRAMS USING DIFFERENT PLAYGROUNDS

In this section, you will create programs to help your robot move through different playgrounds.
Each playground has a unique layout that challenges you to plan and code the robot’s
movement carefully.

Coral Reef Cleanup
In the VEXcode VR simulation, the coral reef environment teaches about the importance of
keeping oceans clean. The robot is programmed to collect trash from the seabed, showing how
technology can help protect marine ecosystems and promote environmental awareness.
