C++#

This guide provides detailed information on how to use the C++ commands in VEXcode EXP. Here, you will learn how to read and understand each command, with comprehensive descriptions, parameters, and usage examples.

Enabling the VEX Namespace#

In C++, classes from the VEX library are accessed using the vex:: namespace prefix, such as vex::color. However, you can simplify your code by enabling the entire VEX namespace at the beginning of your file. To do this, add the statement using namespace vex; at the top of your project. Once enabled, you can directly use VEX classes without the vex:: prefix, allowing you to write color instead of vex::color.

Understanding the Command Entries#

Each command entry in the API Reference includes the following components:

  • Command Name and Signature: This is the name of the command and its parameters.

  • Description: A brief explanation of what the command does.

  • Blocking/Non-Blocking: Indicates whether the command waits for completion before moving to the next command.

  • Parameters Table: Lists and describes the parameters that the command accepts.

  • Returns: Describes what the command returns, if applicable.

  • Example: Provides a sample code snippet demonstrating how to use the command.
