Create A Game

Step-by-Step Code

First, create 3 objects →

an object of your choice that will be falling
a broken version of that object
an object that will catch those objects

Within the first 2 objects, go to costumes and add both the broken versions and
unbroken, so within each of the first 2 objects you should have 2 costumes

1. Bowl Movement

This part of the code controls the movement of the bowl:

                                when [green flag] clicked: Starts the script when the
                                        green
                                        flag is clicked.
 forever: Repeats the following actions continuously.

                                    
if <key [right arrow] pressed?> then: Checks
                                        if the right arrow key is pressed. If this is true:
                                        change x by (10): Moves the bowl 10 steps to
                                                the right.

                                    
if <key [left arrow] pressed?> then: Checks
                                        if the left arrow key is pressed. If this is true:
                                        change x by (-10): Moves the bowl 10 steps
                                                to the left.

                                    

                            

This allows the player to move the bowl left and right to catch the apples.

2. Game Over Timer

This script waits for a set time before ending the game.

                                when [green flag] clicked: Starts the script when the
                                        game
                                        begins.
wait (100) seconds: Waits 100 seconds before
                                        proceeding.
                                    
say [game over!] for (0.3) seconds: Displays "game
                                        over!"
                                        on the screen for 0.3 seconds.
stop [all]: Ends all scripts in the game

                            

This creates a timer that ends the game after 100 seconds.

3. Apple Spawning and Scoring

This script controls the apples and the scoring.

                                when [green flag] clicked: Starts the script when the
                                        game begins.
set [score] to (0):  Resets the score to 0 at the
                                        beginning.
forever:  Repeats the following actions continuously.
                                        if <touching [Bowl]> then:
                                                Checks if
                                                the apple touches the bowl. If this is true:
                                                
change [score] by (1): Increases the score by 1.

go to [random position]:Moves a new apple to a new random position
                                                                at the top.

set y to (180): Resets the apple's starting y-coordinate
                                                                to the top of the screen.

This creates a timer that ends the game after 100 seconds.

4. Apple Falling and Breaking:

This script handles the falling apples and game-over condition.

                                when [green flag] clicked: Starts the script when the
                                        game begins.
go to x: [random position] y: (180): Place the apple
                                        at the top of the screen in a random horizontal position.
forever:  Repeats the following actions continuously.
                                        change y by (-5):Moves the apple downward by
                                                5 steps every loop.
if <y position <(-170)>
                                                    then:
                                                Checks if the apple's y-coordinate is below -170 (off the bottom of the
                                                screen). If it is true:
                                                
go to x: [random position] y:
                                                                    (180):
 Moves the apple back to
                                                                the top at a random position.

set y to (180):
Resets the y-coordinate to the
                                                                top.

 if <touching color [brown]>
                                            then:Checks if the apple touches the ground (brown color). If this is
                                        true:
                                        switch costume to [costume1]: Changes the
                                                apple's appearance (e.g., to a broken apple).
stop [all]: Ends the game.

This creates a timer that ends the game after 100 seconds.

How It All Works Together

The bowl moves left and right, allowing the player to catch falling apples.
Apples fall from the top and reset to a random position when caught.
Points are awarded for catching apples, and the game ends either when time runs out (100 seconds) or when an apple touches the ground.

Test and Debug Tips:
- You may confuse the backdrop and object, so ensure that you check your code frequently to ensure proper development in the game.
- Be specific about the loops, in scratch there are many types (e.g., if else, if, forever, etc)
- Make sure you add a new costume within the same object and not make a whole new object, again check your code frequently!!
