|When This Sprite Clicked|
The When This Sprite Clicked block is an Events block and a Hat block. Scripts that wear the block will activate once its sprite or clone of the sprite is clicked. Contrary to its definite name, the block will also execute the clone's script when the clone is clicked on.
Clicking on transparent areas of the sprite does not trigger this event, except for transparent areas surrounded by using the hollow rectangle and oval tools in the bitmap editor.
If a sprite is has been hidden by the hide block, when its location is clicked on, the script under the When This Sprite Clicked block will not activate.
In the stage, this block is called When Stage Clicked.
In Scratch 1.4, this block was called When () Clicked. It was automatically filled in with the name of the sprite it was placed on.
In Scratch 2.0, its name was changed to When This Sprite Clicked, likely to make the block name consistent for all sprites. In early versions, it was called When I Am Clicked, but this was changed for unknown reasons.
