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:
- Clearing the screen in a paint program
when this sprite clicked switch costume to [Pressed v] clear switch costume to [Not Pressed v]
- Resetting the penning ground in a pattern maker
wait until <(dots made) > > set [dots made v] to  clear
- Removing stamps in a maze generator or something similar
when I receive [Next maze v] clear broadcast [Generate v]
