Block types
Scratch is a "block-based" programming language. This means instead of writing lines of code to program, we use "blocks". Each block has a specific category that describes what its purpose is.Sprites are the objects that perform actions in a project and these blocks tell the sprites what to do. Code blocks can also tell a stage or backdrop how to behave.
- Define the movement of sprites
- Change the appearance of sprites. Gives the ability to change costumes and apply graphic effects.
- Play audio by recording sounds, using Midi notes and more.
- Trigger scripts or series of code blocks. Consists mainly of hat blocks which start a script.
- Dictate the flow of a project. Provide mechanism for "looping" different blocks and scripts.
- Let multiple sprites interact with themselves and/or the stage. Can determine how two sprites collide for example.
- Allow various mathematical functions within a project. Can be used to modify variables and strings.
- Used to store data in projects, like a name or a score.
- You can create your own blocks!
- At the bottom left of the screen. These blocks let you connect to hardware or access a number of other block types like the pen, or music blocks.
