Timer

Introduction

The VEX AIR Drone Controller’s timer keeps track of elapsed time from the start of a project. It can be used to measure durations, trigger events after a set time, or reset for new timing operations. Below is a list of all available methods:

Action – Control the timer.

• reset – Resets the timer to zero.

Getter – Report the current timer value.

• time – Returns the elapsed time since the project started.

Callback – Trigger functions after a delay.

• event – Calls a function after a specified number of milliseconds, with optional arguments.

Constructor - Create a Timer to track time.

• Timer - Create a new timer object that can be used with these methods.
