Design Pizzas on Scratch

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

Delete the default cat sprite to clear the stage and make room for your pizza game.

Create a pizza base sprite in the Paint Editor and name the sprite "PizzaBase".

In the PizzaBase sprite make three costumes named Small Medium Large by duplicating and resizing the base to three different sizes.

Create at least three topping sprites (for example pepperoni mushroom olive) using the Paint Editor and name each topping sprite.

Program each topping to be draggable: add code so when green flag clicked it remembers its home position and when the topping is clicked it follows the mouse until released.

Add to each topping this single extra rule: after you release it if it is touching PizzaBase then stay where it landed else glide back to its remembered home position.

Make three small button sprites labeled S M L and add code to each button so when clicked it broadcasts the messages "Small" "Medium" or "Large" respectively.

In the PizzaBase sprite add code so when it receives "Small" "Medium" or "Large" it switches to the matching costume.

Make a variable called Score and set Score to 0 when the green flag is clicked so you can keep track of correct orders.

Create a Customer sprite that chooses a random size and a random topping when it receives a "new order" message then shows the order by saying the size and topping and storing them in order variables.

Make a Serve button and add code so when clicked it checks PizzaBase's costume and whether the requested topping is touching PizzaBase then updates Score and tells the player Correct or Try again and broadcasts "new order" to continue.
