Example of Building Games in Scratch Programming Language

Let’s dive into a detailed explanation of how to build a simple catching game in Scratch programming language:

Detailed Example: Creating a Catching Game in Scratch

Objective: Create a game where the player controls a basket to catch falling objects.

Step-by-Step Guide:

Step 1: Setting Up the Stage

Open Scratch: Start by opening Scratch and creating a new project.

Choose a Backdrop: Select a backdrop for your game. You can choose from the library or create your own by drawing or importing an image.

Step 2: Adding Sprites

Choose Sprites: Click on the “Choose a Sprite” button to select sprites for your game.

• Select a sprite for the player’s basket (e.g., a basket sprite from the library).
• Add another sprite for the falling object (e.g., a ball, fruit, or any item you want the player to catch).

Step 3: Programming the Basket Sprite

Select the Basket Sprite: Click on the basket sprite to begin programming its behavior.

Coding Movement:

• Use the Events category to start the game when the green flag is clicked (when green flag clicked block).
• Use a Forever Loop to continuously check for player input (forever block).
• Use If Statements to detect arrow key presses and move the basket accordingly (if <key [arrow keys] pressed?> then blocks).

Example:

when green flag clicked
forever
  if <key [right arrow v] pressed?> then
    move (10) steps
  end
  if <key [left arrow v] pressed?> then
    move (-10) steps
  end
end

Step 4: Programming the Falling Object

Select the Falling Object Sprite: Click on the falling object sprite to program its behavior.

Coding Falling Behavior:

• Use the Events category to start the falling behavior when the green flag is clicked.
• Use a Forever Loop to make the object move downward continuously (forever block).
• Use Motion blocks to control the downward movement (move (10) steps or as desired).

Check if the object reaches the bottom of the stage using If Statements and handle conditions like bouncing back or resetting position.

Example:

when green flag clicked
forever
  move (5) steps
  if <y position < [-180 v]?> then
    go to [random position v]
  end
end

Step 5: Interaction and Scoring

Detecting Interaction:

• Use Sensing blocks to detect when the basket sprite touches the falling object sprite (if <touching [basket v]?> then block).
• Upon collision, update the score, play a sound effect, and reset the object’s position to simulate catching.

Example:

when green flag clicked
forever
  move (5) steps
  if <y position < [-180 v]?> then
    go to [random position v]
  end
  if <touching [basket v]?> then
    change [score v] by (1)
    play sound [pop v]
    go to [random position v]
  end
end

Step 6: Game Over Condition

Setting Game Over:

• Create a condition for when the falling object reaches the bottom of the stage without being caught.
• Broadcast a message or display a game over screen when the condition is met.

Example:

when green flag clicked
forever
  move (5) steps
  if <y position < [-180 v]?> then
    go to [random position v]
  end
  if <y position < [-200 v]?> then
    broadcast [game over v]
    stop [all v]
  end
  if <touching [basket v]?> then
    change [score v] by (1)
    play sound [pop v]
    go to [random position v]
  end
end

Step 7: Adding Polish

Enhancing the Game:

• Include visual elements like displaying the score and timer on the screen.
• Add background music and sound effects to enhance gameplay experience.
• Implement additional features such as levels, power-ups, or obstacles to increase game complexity and replayability.

Step 8: Testing and Sharing

Test the Game: Click the green flag to test your game within Scratch. Play through different scenarios to ensure everything works as expected.

Share Your Game: Publish your game on the Scratch community platform to share with others. Receive feedback, collaborate with fellow Scratch users, and explore remixing options to further improve and expand your game.
