计时器#
介绍#
The VEX AIR Drone Controller’s timer keeps track of elapsed time from the start of a project. It can be used to measure how long something takes, trigger events after a set time, or reset for new timing operations.
以下是所有可用块的列表：
重置计时器——将计时器重置为零。
timer in seconds — Reports how much time has passed.
when timer — 计时器超过指定时间后运行一堆块。
重置定时器#
The reset timer stack block resets the timer to zero. This can be used to start timing a new part of a project without restarting the whole project.

计时器（以秒为单位）#
The timer in seconds reporter block reports the time since the timer was last reset, as a decimal in seconds. The timer is automatically reset at the start of a project. This block can be used to time how long it takes the drone to complete different actions.
