Beginners Guide To Scratch (VERY Simple)

Game storyline (what the tutorial game is “about”)

• You play as a cat collecting falling/moving bananas to gain points.
• An enemy bat constantly homes in on the cat.
• If the bat touches the cat, the game ends and a “you died” message appears.
• The tutorial also scales up difficulty by duplicating bananas and bats.

Gameplay / mechanics taught (Scratch concepts put into a mini game)

Core objects

• Sprites (player cat, collectibles bananas, enemy bat, and UI text)
• Costumes for animation (cat running, bananas, bat movement frames)
• Backdrops for the game background

Player controls (movement)

• Player movement starts when the green flag is clicked.
• Movement is driven by:
  • A Forever loop
  • An if condition checking keyboard input
  • Position updates using change X / change Y

Keys mapped:

• D / A: move right/left (change X)

• W / S: move up/down (change Y)

• Step size is customizable (shown with an example like 5 pixels for smoother/slower movement).

Collecting bananas + scoring

• Add a banana sprite and position it off-screen/start area.
• The banana runs a loop that checks:
  • if touching cat

When touching:

• change score by 1
• move banana to a random position (so it can be collected repeatedly)

Spawning / setting up the scene

• Bananas are positioned using coordinates (examples include placing one at the top and duplicating to create multiple banana targets).
• The cat and banana(s) are re-positioned when the game starts (e.g., cat to center, banana(s) spawn at the top).
• Backdrop drawing is introduced (simple rectangle/circle/paint tools), and renamed as a background costume/backdrop.

Enemy bat behavior (chasing + losing)

A bat enemy sprite is set up with:

• motion: moves forward continuously
• turning: constantly points toward the cat

Logic used:

• In a Forever loop, repeatedly:

  • move a small amount (example shown: move 2 steps)
  • point towards cat

• Rotation style is set so the bat doesn’t rotate oddly while still chasing (set rotation style to “don’t rotate”).

Death condition:

• if touching cat
• stop all (halts the game immediately)

Adding a death screen:

• Create a text sprite saying “you died”
• Use broadcast messages:
  • Bat broadcasts a custom message (named “died”)
  • UI text sprite shows when it receives “died”
  • The text is hidden at game start

Animation timing tip (smooth running)

Instead of cycling costumes instantly at full speed, the tutorial adds:

• wait ~0.1 seconds between next costume

This makes the cat animation look more natural.

Strategies / key tips highlighted

• Use a Green Flag start block to initialize the game logic.
• Use Forever + If patterns for input handling and collision checks.
• Costumes = animations: switch costumes to animate sprites.
• Variables for score:
  • set score to 0 on start
  • increment when the player touches collectibles
• Use “touching [sprite]” for simple collision detection.
• Use Broadcast/Receive for cross-sprite events (like showing the death message).
• Duplicate sprites to scale gameplay (multiple bananas, multiple bats).
• Add a small wait when cycling costumes to prevent ultra-fast animations.
• A minor issue is mentioned: sometimes collision/collection can happen right as the game starts unless you adjust starting waits/positions (the video suggests using wait 0 seconds and/or simplification).
