🇬🇧 English: Step 1: Prepare the Sprites

Add the necessary sprites for our game.

• Use the Cat sprite that's already there - this will be the character we need to catch
• Add a Ball sprite or Wand sprite - this will be the character we control
• Click on Backdrops and choose a background you like, such as Garden

Why? The ball or wand follows your mouse, and you try to touch the cat with it!

🇬🇧 English: Step 2: Create a Score Variable

Create a variable to store and display the score.

1. Go to the "Variables" category (orange blocks)
2. Click "Make a Variable"
3. Name it "Score"
4. Select "For all sprites"

Remember: Variables are like boxes that store information. This one will count how many times you catch the cat!

🇬🇧 English: Step 3: Code for the Ball (The Controller)

Make the ball follow the mouse pointer so you can control it.

Explanation of each block:

• when green flag clicked - This starts the program when you click the green flag
• set Score to 0 - This resets the score to zero at the beginning
• forever - This creates a loop that repeats forever
• go to mouse-pointer - This makes the ball move to wherever your mouse is

How to build it: Drag the "when green flag clicked" block first. Then snap the "set Score to 0" below it. Then wrap everything in a "forever" loop. Put "go to mouse-pointer" inside the forever loop.

🇬🇧 English: Step 4: Code for the Cat (The Target)

Make the cat run away randomly and count points when it's caught.

The cat needs 2 separate scripts running at the same time!

Script 1: Random Movement

Explanation:

• move 5 steps - The cat walks forward 5 steps
• if on edge, bounce - When the cat hits the edge, it bounces back
• turn right (pick random 1 to 10) - The cat randomly turns between 1 and 10 degrees to make unpredictable movement

Tip: You can change "5 steps" to make the cat faster or slower! Try 10 for fast, or 3 for slow.

Script 2: Detect Touching (Collision Detection)

Explanation:

• if touching Ball? - This checks if the cat is touching the ball sprite
• change Score by 1 - Add 1 point to the score
• play sound meow - Play a meow sound effect when caught
• go to random position - Move the cat to a random spot on the stage

This is how the game works! Every time your ball touches the cat, you get a point and the cat jumps to a new location!

🇬🇧 English: Step 5: Test and Improve

Try playing your game and make it better!

1. Click the green flag to start the game
2. Move your mouse to catch the cat
3. Watch the score increase
4. Try playing multiple times!

🇬🇧 English: Try creating your own game! You can make:

• A multi-scene adventure game
• A rhythm or music game
• An educational quiz game
• An animated story
• A racing game
• A ghost catching game
• A collection or treasure hunt game

Remember: The best way to learn is by doing! Don't be afraid to experiment and try new things.
