Scratch Programming Basics

Block Coding

• Scratch uses block coding, a visual programming language that replaces text-based code with color-coded blocks.
• Blocks are dragged and dropped into a scripting area to create programs.
• This approach makes programming more accessible and intuitive for beginners, especially children.

Animation Creation

• Scratch allows users to create animations by manipulating sprites (characters or objects) on a stage.
• Users can create animations by:
  • Changing sprite costumes or backdrops
  • Moving sprites across the stage
  • Adding sound effects or music
  • Creating simple animations using motion blocks

Conditional Statements

• Conditional statements (if-then statements) are used to make decisions in Scratch programs.
• Conditional statements evaluate a condition and execute a block of code if the condition is true.
• Examples of conditional statements in Scratch:
  • If-then statements: if [condition] then [action]
  • If-else statements: if [condition] then [action] else [alternative action]

Looping Techniques

• Loops are used to repeat a block of code in Scratch.
• Types of loops in Scratch:
  • Forever loops: forever [action]
  • Repeat loops: repeat [number] [action]
  • Until loops: repeat until [condition] [action]
• Loops can be used to create animations, games, and interactive stories.

Game Development

• Scratch is commonly used to create 2D games, such as platformers, puzzle games, and racing games.
• Game development in Scratch involves:
  • Creating game sprites and backdrops
  • Designing game mechanics and rules
  • Adding scoring and lives systems
  • Creating user interfaces and menus
• Scratch games can be shared online and played by others in the Scratch community.
