▶ Programming languages contain a set of instructions that a computer follows to complete
a task.
▶ Blocks in the block palette are divided into various categories such as Motion, Looks, Control, Sound,
and Events, etc.
▶ Motion blocks are used to control the movement of a Sprite.
▶ Events block controls how the blocks in a script will start to run, if a particular action is
done.
▶ Looks blocks let you modify the sprite’s costumes and colours.
▶ The Sound block category instructs the sprite to play music.
▶ The Operators block category lets us perform mathematical operations.
▶ Variables are named locations where you can store information.
▶ A global variable can be created on any sprite but its value can be accessed or modified by other
sprites used in the project.
▶ Local variables can only be accessed or modified from the sprite where they were created.
▶ Sensing blocks are colour-coded light-blue, and are used to control the movement of the sprite in a
better manner.
