Code a Coin Catcher Game in Scratch

Open Scratch and start a new project so you have a blank stage to build your game.

Remove the cat sprite and create or pick a catcher sprite and place it centered near the bottom of the stage.

Add code to the catcher so it can move left and right using the arrow keys by making scripts that change x by 10 when the right arrow is pressed and change x by -10 when the left arrow is pressed.

Create or choose a round coin sprite and make a bright coin costume so it is easy to see as it falls.

Make a variable called Score for all sprites and add a script to set Score to 0 when the green flag is clicked.

On the coin sprite add a spawning script: when the green flag clicked hide then forever create clone of myself wait pick random 0.5 to 1.5 seconds.

On the coin sprite add a clone script so each clone shows then goes to x pick random -200 to 200 y 180 then repeats moving down by a fall amount until it touches the catcher or goes below the stage then deletes itself.

Inside the clone script add a check so if the coin touches the catcher it plays a popping sound changes Score by 1 and then deletes the clone.

Create a variable called FallSpeed for all sprites set FallSpeed to 5 when the green flag is clicked and use change y by -FallSpeed in the clone falling loop.

Add a tiny script to increase challenge by changing FallSpeed by 1 every time Score reaches 10 so the coins fall faster as you score more.

Test your game by clicking the green flag and then tweak the coin spawn wait times sizes and FallSpeed until it feels fun and fair.

Share your finished Coin Catcher game on DIY.org so everyone can see how you coded timing logic scoring and sound effects.
