The Clear block is a Pen block and a Stack block. The block removes all marks made by the pen or stamps. This block is the only Pen block that the Stage can use.

Example Uses

This block is used in almost all projects involving the pen (especially graphic editor simulations), as clearing the screen once the project starts would be a main priority.

Some common uses for the Clear block are:

  • Clearing the screen in a paint program
when this sprite clicked
switch costume to [Pressed v]
clear
wait until <not<mouse down?>>
switch costume to [Not Pressed v]
  • Resetting the penning ground in a pattern maker
wait until <(dots made) > [50]>
set [dots made v] to [0]
clear
  • Removing stamps in a maze generator or something similar
when I receive [Next maze v]
clear
broadcast [Generate v]
  • Refreshing the screen to draw the next frame
when GF clicked
forever
    tick::custom
end
define tick
clear //Clear the screen
... //Code for redrawing the updated animations
