Timer#

Introduction #

The VEX V5’s Brain has a timer that 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 blocks:

reset timer – Resets the timer to zero.
timer in seconds – Returns the current elapsed time in seconds.
when timer – Runs a stack of blocks after the timer exceeds a specified time.

A stack of blocks that begins with a when started block, followed by a comment block reading Print the time on the screen and reset the time after five seconds. Inside a forever loop, a reset timer block starts the cycle. A while loop runs while the timer is less than or equal to three seconds, repeatedly clearing row 1, setting the cursor, and printing the timer value on the screen.#

timer in seconds #

The timer in seconds block returns the elapsed time since the timer was last reset, as a float in seconds.

The timer in seconds reporter block.#

(计时器秒数)

Parameters	Description
	This block has no parameters.

Example

A stack of blocks that begins with a when started block, followed by a comment block reading Display the time after 2 seconds have passed. A wait until block pauses execution until the timer reaches or exceeds two seconds. Once this condition is met, a print block displays the timer value on the screen.#

当开始
[Display the time after 2 seconds have passed.]
等到 <(计时器秒数) [math_greater_than_or_equal_to v] [2]>

when timer #

The when timer block activates the attached stack of blocks after a specified amount of time.

The when timer hat block.#

当计时器> [1] 秒

Parameters	Description
time	Specifies the number of seconds before the attached stack of blocks starts. Accepts both whole and decimal numbers.

Example

A stack of blocks that begins with a when timer > 2 seconds block, followed by a comment block reading Play a fail after 2 seconds. Once the timer exceeds two seconds, a play sound block plays the fail sound.#

当计时器> [2] 秒
[Display a message after 2 seconds.]
