Timer

Introduction

The Timer in VEXcode VR allows you to track elapsed time and perform actions based on time intervals. With various methods for time management, you can create precise and timed operations within your program.

Below is a list of all methods:

Methods – Control and interact with the Brain’s timer.

• timer_reset – Resets the timer to zero.

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

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

timer_reset

timer_reset sets the timer to zero.

Usage:
brain.timer_reset()

Parameters	Description
	This method has no parameters.

def main():
    # Reset the timer every 3 seconds
    while True:
        brain.clear()
        brain.print(brain.timer.time(SECONDS))
        if brain.timer_time(SECONDS) > 3: 
            brain.timer_reset()
        wait(5, MSEC)

# VR threads — Do not delete
vr_thread(main)

timer_time

timer_time returns the current elapsed time of the timer as a float.

Usage:
brain.timer_time(units)

Parameters	Description
units	The unit that represents the time: SECONDS

def main():
    # Display the current time on the timer
    while True:
        brain.clear()
        brain.print(brain.timer_time(SECONDS))
        wait(50, MSEC)

# VR threads — Do not delete
vr_thread(main)

timer_event

event calls a function after a specified amount of time.

Usage:
brain.timer_event(callback, delay)

Parameters	Description
callback	A function to execute when the timer event occurs.
delay	The delay before the function is called, in milliseconds.

def timer_event():
    # Drive forward
    drivetrain.drive_for(FORWARD, 200, MM)

def main():
    # Drive forward after a 5000 millisecond delay
    brain.timer_event(timer_event, 5000)

# VR threads — Do not delete
vr_thread(main)
