Timer

Introduction

The Timer in VEX GO allows you to track elapsed time and perform actions based on time intervals. It can be used to measure how long something takes or reset for new timing operations.

Below is a list of all methods:

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

• reset – Resets the timer to zero.

• time – Returns how much time has passed.

• event – Registers a function to be called after a specified number of milliseconds.

Constructor – Create additional timers.

• Timer – Creates an additional timer.

reset

reset sets the timer to zero. This can be used to time additional sections of code within the same project.

Usage:
timer.reset()

Parameters	Description
	This method has no parameters.

# Build Used: Super Code Base 2.0
def main():
    # Reset the timer when the bumper is pressed
    while True:
        console.clear()
        console.print(timer.time(SECONDS))
        wait(50, MSEC)
        if bumper.is_pressed():
            timer.reset()

# Start threads — Do not delete
start_thread(main)

time

time returns the time since the timer was last reset as a decimal. The timer is automatically reset at the start of a project.

Usage:
timer.time(units)

Parameters	Description
units	The unit that represents the time: MSEC (default) – milliseconds, or SECONDS

# Build Used: Super Code Base 2.0
def main():
    # Display the time until the bumper is pressed
    while True:
        console.clear()
        console.print(timer.time(SECONDS))
        wait(50, MSEC)
        if bumper.is_pressed():
            timer.reset()

# Start threads — Do not delete
start_thread(main)

event

event calls a function after a specified amount of time passes.

Usage:
timer.event(callback, delay, arg)

Parameters	Description
callback	A function to execute when the timer event occurs.
delay	The delay before the function is called, in milliseconds.
arg	Optional. A tuple containing arguments to pass to the callback function. See Functions with Parameters for more information.

# Build Used: Super Code Base 2.0
def timer_event():
    drivetrain.drive_for(FORWARD, 200, MM)

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

# Start threads — Do not delete
start_thread(main)

Constructors

Timer

Timer creates a new timer. A Timer object will immediately begin counting the moment it is created and will work with all timer methods.

Usage:
my_timer = Timer()

Parameters	Description
	This constructor has no parameters.

def main():
    # Display the time of two timers
    wait(2, SECONDS)
    timer_1 = Timer()
    while True:
        console.clear()
        console.print("Timer: ", timer.time(SECONDS))
        console.new_line()
        console.print("timer_1: ", timer_1.time(SECONDS))
        wait(15, MSEC)

# Start threads — Do not delete
start_thread(main)
