Study Notes
Coding with Scratch
- Scratch is a program application for coding
- It has different block categories for coding (e.g., Motion, Looks, Sound, Events, Control, Sensing, Operators, Variables)
- Sprites are characters to be coded in Scratch
- The stage is where the sprites perform a given task
- Variables can be used to store and access data (e.g., storing points or other numerical or textual information)
- Events are actions or situations that happen in a program (e.g., when a green flag is clicked, or when a sprite touches another sprite)
- Control blocks control the order of events in a script (e.g., "repeat until", "forever", "if/else")
- Sensing blocks are used to detect situations like when sprites touch each other or the mouse pointer, or check if a condition is true.

- Operators blocks are used for mathematical operations. (e.g., pick random numbers).
- Scratch 3.0 can be used on mobile devices
Flowcharts and Conditional Looping
- Flowcharts use diagrams to show steps in a program
- Each step is shown in a rectangle
- Decisions are shown in a diamond shape
- Flowcharts help to plan complex programs
- Scratch uses blocks to translate a flowchart for coding.
- Input is received using an "ask" block, which creates a variable that can be used in conditional statements.

- The "if...else" statement in Scratch translates to the Yes and No arrows from a flowchart
- Looping repeats specific blocks until a certain condition is met, based on the flowchart (e.g., repeat until a variable reaches a certain value, forever loops).
- A dry run (checking the logic step-by-step) is advised when using flowcharts
Loops
- Repeat X times block repeats a sequence of blocks for a set number of times
- Forever block repeats a sequence of blocks infinitely
- Repeat until block repeats a sequence of blocks until a specific condition is true
- The repeat loop allows a program to repeat an action multiple times
- Variables are often used with loops to keep track of a counter.
- Conditional loops allow the loop to run only if a specific condition is true.
Variables and Loops
- Variables are used to store data and used in loops to perform actions (e.g., store user input from an "Ask" block, store values for calculation in loops)
- Important to initialize variables before use, such as setting variables to initial values.
- Loops and variables are very often used together.
- Variables can be used to control the behavior of loops.
- Variables are important for storing, updating and using data during a program.
Game 1: Race of 2 Sprites
- Sprites can be moved, have their appearance changed, and use random numbers for speed adjustments. (e.g., generate a random number using "pick random 5 to 10").
- The program includes a loop to make sprites move based on speed.
- Sprites move until they reach a defined finish line (using "touching" block)
- Cartesian coordinates are used to describe sprite positions on the stage.
- X and Y values are used to position sprites.
- Sprites automatically stop when they reach the finish line.
- Variables record sprite speed (e.g., AverySpeed).
Game 2: To the Moon!
- The program includes backdrop switching and sprite movement.
- It uses specific points on the screen for sprite positions (using "go to x:y: coordinates").
- The sprite's direction can be changed ("point in direction").
- The sprite's costume or appearance can change during the program ("switch costume").
- The program involves movement, turning and landing to simulate a rocket's journey to the moon. (e.g., using "glide to x, y for seconds").
- The program includes the use of a loop to control the rocket's turning actions.
- The program displays messages to indicate landing with "say" commands.
- The program uses the "switch backdrop" block to change the background image.
- The program uses the "switch costume" to change a sprite's appearance.
- The Cartesian coordinate system to position the rocket
- The program uses the "repeat until" loop.
