#1. What do you think this script does?

After 10 seconds, changes the background from Forest to Urban

Nothing

Changes the background from Urban to Forest after 10 seconds

Keeps alternating between different backgrounds

#2. When the backdrop changes, which command is being carried out by the dog script?

say 'I have no idea'

say 'Of course I will!'

say 'We've made it to town'

Wait 2 secs

#3. If the backdrop changes after 10 seconds, what command will the cat be doing?

Wait 2 secs

say "Do you know where we are?" for 2 seconds

say "Will you help me find my friends" for 2 seconds

Wait 6 secs

#4. This project adds background sound to the scene. Why do you think the volume is set to 30%?

Because at 30 it is louder than 10.

Because it is quieter than any main character.

If it is any other number it won't work.

So that it plays the sound for 30 seconds and then stops.

Volume is how loud the sound is…

Volume percentage goes from 0% (silent) to 100% (full volume)

Volume can be set at any number – the higher the number, the louder the volume.

#5. There might be a problem with this code.

The first sound should start with a 'play sound until done' block too.

If the first sound is longer than 10 seconds, it will carry on during the next scene

The sound will play, stop, then wait 10 seconds before playing the next sound

‘Start sound’ will carry on through the code blocks whilst the sound is playing

‘Play sound until done’ will stop doing the code blocks until the sound has finished.

The two commands are correct, but the first sound will just keep playing.

Score and next steps
