Step 2 - Efficient Looping

This time, let’s tell our chicken in this level how to reach the coin with the least amount of instructions possible. That’s called ‘being efficient’.

> Click on Level 2 in the levels bar.

> Think about how many movements the chicken will need to make to get to the coin.

It looks like the chicken will need to move up twice, and left twice.

> Right-click on the chicken and select Edit Script.

We can use two "repeat" blocks to achieve our efficient instructions.

> Open Events and drag "When the level starts" into the work space.

> Open Control Flow and drag two "repeat 10 times" blocks into the "When the level starts" block, one over the other.

> Open Events and drag two "Broadcast message" blocks into the work space. Place one "broadcast" block in each “repeat” block.

> The chicken first needs to move up two times, so change the first "repeat 10 times" to “repeat 2 times”. Also change “broadcast message” to “broadcast up”.

> The chicken then needs to move left two times, so change the second "repeat 10 times" block to “repeat 2 times”, and change the second “broadcast message” block to “broadcast left”.

> Click Play to see if our code works!

Did the chicken reach the coin? Great! Let’s continue to the next step.

If not, have a look back over your Script and see if you can spot the bugs.
