Introduction

Events is one of the ten categories of default Scratch blocks. They are color-coded light yellow and are used to sense events, which trigger scripts to run. Event blocks are essential for every project: without the hat blocks from this category, a project would not be able to begin except by manually running scripts.

PictoBlox Blocks

Scripts that wear this block will activate once the Green Flag has been clicked — these scripts can activate other scripts and enable the entire program. Without this block, the only way a project could run would be that it would sense the pressing of a key or clicking a sprite; the project would only last until all scripts depending on the starting scripts have ended.
Scripts placed underneath this block will activate when the specified key is pressed.
Scripts that wear this block will be triggered once the specified backdrop has been switched to on the Stage.
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.
Scripts that begin with this block will be invoked once the specified broadcast has been sent by a calling script. If a Forever block is sending the broadcast faster than the attached script can finish running, the script will restart without reaching the blocks at the end. This can be avoided by using Broadcast () and Wait.
The block sends a broadcast throughout the whole Scratch program. Any scripts in any sprites that are hatted with the When I Receive () block that is set to a specified broadcast will activate. This broadcast block lets scripts send broadcasts without any waits in its script (unlike the Broadcast () and Wait block). Broadcasts are a good way to have sprites and scripts communicate.
The block sends a broadcast throughout the whole Scratch project — any scripts that are halted with the When I Receive () block and are set to the broadcast will activate. This broadcast block lets scripts send broadcasts, and have them wait until all scripts are activated by the broadcast ends.

Block Coding Examples

Ball Movement

The example demonstrates how to add movement to a sprite using the key detection hat block.

Change costume when Clicked

The example demonstrates the costume change and gliding to the random location when clicked.

Falling Tobi

The example demonstrates the use of clone and gliding function in Sprite. 

Follow the Mouse

The example demonstrates how to make the sprite follow the mouse.

LED Control with Keys

The example demonstrates how to control the glowing LED using the keyboard keys.

Making a Sprite glide to Random Location

The example demonstrates how to make the sprite glide to a random position on the stage when it is clicked.

Show and Hide

The example demonstrates the show and hides of the sprite using the buttons.

Walking Tobi

The example demonstrates the wall bouncing of the sprite and rotation style.
