The Timer block is a sensing block that reports the amount of time since the project was loaded or the timer was last reset. This block is almost always used with the Reset Timer block — usually the timer must be reset at the beginning of a project for the Timer block to hold the right value.

This block can be displayed as a Stage monitor, though it will only display intervals of 0.1. This value can be made more precise by making a script that constantly sets a variable to the timer.

Example Uses

when gf clicked
set [PersonX v] to (pick random (-240) to (240))
set [PersonY v] to (pick random (-180) to (180))
hide
forever
  switch costume to (Mouse pointer v)
  go to x: (mouse x) y: (mouse y)
  stamp
  switch costume to (Hiding person v)
  go to x: (PersonX) y: (PersonY)
  if <<touching (mouse pointer v)?> and <mouse down?>> then
    show
    say [You found me!] for (2) seconds
    stop [this script v]
  else
    if <(timer) > (5)> then
      reset timer
      set [PersonX v] to (pick random (-240) to (240))
      set [PersonY v] to (pick random (-180) to (180))
    end
  end
  • Showing how long a Scratcher is taking in a project (a variable can also be used for this, but it is not as accurate)
when I receive [Start the homework quiz! v]//the variable timer is showing
reset timer
say [Don't forget to look at the timer to see how much time you've taken up!]
  • Checking if an amount of time is acceptable for advancing to another stage of the project
when I receive [new level v]
reset timer

when I receive [level completion v]
if <(timer) < (30)> then
  say [You beat the level! Let's move onto the next one.] for (3) seconds
  broadcast (new level v)
else
  say [You didn't finish in 30 seconds. Maybe next time.] for (3) seconds
  stop [all v]
end
  • Reacting to the length a button is held down by changing a variable faster:
when this sprite clicked //when the button is clicked
reset timer
change [points v] by (1) //first incrementation
wait until <(timer) > (.4)>
repeat until <<not <mouse down>> or <not <touching [mouse-pointer v]?>>> //since the button has been held long
change [points v] by (1) //add points faster
wait (.1) seconds //wait a small amount of time

Multiple Timers

Multiple timers can be simulated with variables which record the time at the beginning of the session.

when gf clicked
reset timer
wait (1) seconds
set [timerA v] to (timer)
wait (2) seconds
say (join [The old timer is:] (timer)) for (1) seconds
say (join [The new timer is:] ((timer) - (timerA))) for (1) seconds
