THE OFFICIAL RASPBERRY PI BEGINNER’S GUIDE

So that the player knows they have scored, add a play sound cheer block and a
say 200 points for 2 secs block inside the if then block. Finally, add a broadcast new arrow
block to the very bottom of the block stack, below and outside the if then block, to give the
player another arrow each time they fire one. Click the green flag to start your game, and try
to hit the yellow bull’s-eye: when you do, you’ll be rewarded with a cheer from the crowd and a
200-point score!

The game works, but is a little challenging. Using what you’ve learnt in this chapter, try extending
it to add scores for hitting parts of the target other than the bull’s-eye: 100 points for red, 50 points
for blue, and so on.

CHALLENGE: CAN YOU IMPROVE IT?

How would you make the game easier? How would you

make it more difficult? Can you use variables to have the

player’s score increase as they fire more arrows? Can you

add a countdown timer to put more pressure on the player?
