# Scratch Cheatsheet ## Unique Features - Visual programming language - Drag-and-drop interface - Designed for teaching programming concepts to children - Event-driven programming ## Variables - Create variable: `set [variable name] to [value]` - Change variable: `change [variable name] by [value]` - Show variable: `show variable [variable name]` - Hide variable: `hide variable [variable name]` ## Functions - Define function: `define [function name]` - Call function: `call [function name]` ## Loops - Forever loop: `forever` - Repeat loop: `repeat [number] times` - While loop: `repeat until <[condition]>` - For loop: `for [variable] from [start] to [end]` - For each loop: `for each [variable] in [list]` ## Conditionals - If statement: `if <[condition]> then` - If-else statement: `if <[condition]> then else` - If-else if statement: `if <[condition]> then else if <[condition]> then` ## Event Handling - Event definition: `when [event]` - Broadcast event: `broadcast [event]` - Receive event: `when I receive [event]` ## Motion - Move: `move [value] steps` - Turn: `turn [value] degrees` - Go to: `go to x: [value] y: [value]` - Glide: `glide [value] secs to x: [value] y: [value]` ## Looks - Show: `show` - Hide: `hide` - Switch costume: `switch costume to [costume]` - Next costume: `next costume` - Change size: `change size by [value]` - Set size: `set size to [value]%` ## Sound - Play sound: `play sound [sound]` - Stop sound: `stop all sounds` - Change volume: `change volume by [value]` - Set volume: `set volume to [value]%` ## Resources - [Scratch Project Ideas](https://scratch.mit.edu/ideas) - [ScratchEd](https://www.scratch.mit.edu/educators) - [Scratch Wiki](https://en.scratch-wiki.info)
