1. Which block can be used to send a message from the button to the Beatbot?

  • {"func":"blockControlBroadcast","values":[{"type":"string","value":""}]}
  • {"func":"blockSoundPlayDrum","values":[{"type":"choice","value":"35 Acoustic Bass Drum"},{"type":"number","value":"0.2"}]}
  • {"func":"blockSoundPlay","values":[{"type":"string","value":""}]}
  • {"func":"blockSoundPlayUntilDone","values":[{"type":"string","value":""}]}

2. You have an Actor that will play a punch sound when they receive the message 'punch'. What will happen if we remove the 'Broadcast' block from the following code?
{"func":"registerKeyTrigger","values":[{"type":"choice","value":"left arrow"}],"next":{"func":"blockLooksNextCostume","next":{"func":"blockControlWait","values":[{"type":"number","value":".3"}],"next":{"func":"blockLooksSwitchCostume","values":[{"type":"string","value":"blue button off"}],"next":{"func":"blockControlBroadcast","values":[{"type":"string","value":"punch"}]}}}}}

  • The message will be broadcast and the punch sound will play
  • The message will not be broadcast and the punch sound will play
  • The message will be broadcast and the punch sound will not play
  • The message will not be broadcast and the punch sound will not play

3. What does the following code do?
{"func":"registerKeyTrigger","values":[{"type":"choice","value":"right arrow"}],"next":{"func":"blockLooksNextCostume","next":{"func":"blockControlWait","values":[{"type":"number","value":".3"}],"next":{"func":"blockLooksSwitchCostume","values":[{"type":"string","value":"blue button off"}],"next":{"func":"blockControlForever","containers":[{"func":"blockControlBroadcast","values":[{"type":"string","value":"punch"}]}]}}}}}

  • When the right arrow is pressed, the button will change costumes and the 'punch' message will be sent once
  • When the right arrow is pressed, the button will change costumes and the 'punch' message will be sent repeatedly until the end of the program
  • When the right arrow is pressed, the button will change costumes but the 'punch' message will not be sent
  • When the right arrow is pressed, the button will change costumes and the 'punch' message will be sent ten times

4. True or False: In the following code, the punch sound will still play if we change what message we are broadcasting.
{"func":"registerKeyTrigger","values":[{"type":"choice","value":"left arrow"}],"next":{"func":"blockLooksNextCostume","next":{"func":"blockControlWait","values":[{"type":"number","value":".3"}],"next":{"func":"blockLooksSwitchCostume","values":[{"type":"string","value":"blue button off"}],"next":{"func":"blockControlBroadcast","values":[{"type":"string","value":"punch"}]}}}}}

  • True
  • False

5. True or False: In the following code, the punch sound will still play if we remove the {"func":"blockLooksNextCostume"} block.
{"func":"registerKeyTrigger","values":[{"type":"choice","value":"left arrow"}],"next":{"func":"blockLooksNextCostume","next":{"func":"blockControlWait","values":[{"type":"number","value":".3"}],"next":{"func":"blockLooksSwitchCostume","values":[{"type":"string","value":"blue button off"}],"next":{"func":"blockControlBroadcast","values":[{"type":"string","value":"punch"}]}}}}}

  • True
  • False

6. Elizabeth wants the first song in the following code to finish playing before the second song starts, but the code is skipping the first song and playing the second song. What can she do to play the songs correctly?
{"func":"blockSoundPlay","values":[{"type":"string","value":"Song1"}],"next":{"func":"blockSoundPlay","values":[{"type":"string","value":"Song2"}]}}

  • The songs cannot be played correctly
  • Replace the first {"func":"blockSoundPlay","values":[{"type":"string","value":""}]} with {"func":"blockSoundPlayUntilDone","values":[{"type":"string","value":""}]}
  • Replace the second {"func":"blockSoundPlay","values":[{"type":"string","value":""}]} with {"func":"blockSoundPlayUntilDone","values":[{"type":"string","value":""}]}
  • Add a {"func":"blockControlForever","containers":[null]} block around the code block

7. True or False: An Actor can only have one {"func":"blockControlBroadcast","values":[{"type":"string","value":""}]} block.

  • True
  • False

8. What block is needed to receive the message from a broadcast block?

  • {"func":"registerBroadcastTrigger","values":[{"type":"string","value":""}]}
  • {"func":"blockControlBroadcast","values":[{"type":"string","value":""}]}
  • {"func":"blockSoundPlayUntilDone","values":[{"type":"string","value":""}]}
  • {"func":"registerFlagTrigger"}

9. What code block will play an entire song five times in a row?

  • {"func":"blockControlRepeat","values":[{"type":"number","value":"5"}],"containers":[{"func":"blockSoundPlayUntilDone","values":[{"type":"string","value":"Song"}]}]}
  • {"func":"blockControlRepeat","values":[{"type":"number","value":"5"}],"containers":[{"func":"blockSoundPlay","values":[{"type":"string","value":"Song"}]}]}
  • {"func":"blockControlForever","containers":[{"func":"blockSoundPlay","values":[{"type":"string","value":"Song"}]}]}
  • {"func":"blockSoundPlayUntilDone","values":[{"type":"string","value":"Song"}]}

10. True or False: It is possible to add your own sounds to an Actor.

  • True
  • False

11. What does the following code do?
{"func":"registerFlagTrigger","next":{"func":"blockControlForever","containers":[{"func":"blockSoundPlayDrum","values":[{"type":"choice","value":"35 Acoustic Bass Drum"},{"type":"number","value":"0.2"}]}]}}

  • It plays the drum sound forever when the play button is clicked
  • It plays the drum sound once when the play button is clicked
  • It plays the drum sound forever when the left button is pressed
  • It plays the drum sound forever when the Actor is clicked

12. What is the purpose of the parameter in the {"func":"blockControlBroadcast","values":[{"type":"string","value":""}]} block?

  • It specifies which message is being broadcast
  • It specifies which sound will be played
  • It specifies the name of the Actor
  • It specifies which drum sound will be played

13. What does the following code do?
{"func":"registerTrigger","values":[{"type":"wrapper","func":"valueSensingMouseDown"}],"next":{"func":"blockSoundPlay","values":[{"type":"string","value":"Song"}]}}

  • It plays the song when the mouse is pressed
  • It plays the song when the play button is clicked
  • It plays the song when the Actor is clicked
  • It plays the song when the spacebar is pressed

14. What will happen if you move the {"func":"blockControlBroadcast","values":[{"type":"string","value":"punch"}]} block to the bottom of the following code?
{"func":"registerKeyTrigger","values":[{"type":"choice","value":"left arrow"}],"next":{"func":"blockControlBroadcast","values":[{"type":"string","value":"punch"}],"next":{"func":"blockLooksNextCostume","next":{"func":"blockControlWait","values":[{"type":"number","value":".1"}],"next":{"func":"blockLooksSwitchCostume","values":[{"type":"string","value":"blue button off"}]}}}}}

  • The BeatBot will play its sound before the button changes costumes
  • The BeatBot will play its sound after the button changes costumes
  • The BeatBot will not play any sounds
  • The BeatBot will play its sound while the button changes costumes

15. Which of the following sets of code blocks can be used to create an animation for an Actor?

  • {"func":"registerFlagTrigger"}, {"func":"blockControlForever","containers":[null]}, {"func":"blockLooksNextCostume"}, {"func":"blockControlWait","values":[{"type":"number","value":""}]}
  • {"func":"blockControlBroadcast","values":[{"type":"string","value":""}]}, {"func":"blockControlWait","values":[{"type":"number","value":"1"}]}
  • {"func":"registerSpriteTrigger"}, {"func":"blockSoundPlay","values":[{"type":"string","value":""}]}
  • {"func":"blockMotionMove","values":[{"type":"number","value":"10"}]}, {"func":"blockLooksNextCostume"}

16. If you wanted to play the sound from the blue button instead of the BeatBot, which of the following blocks will be unnecessary?
{"func":"registerKeyTrigger","values":[{"type":"choice","value":"left arrow"}],"next":{"func":"blockControlBroadcast","values":[{"type":"string","value":"punch"}],"next":{"func":"blockLooksNextCostume","next":{"func":"blockControlWait","values":[{"type":"number","value":".1"}],"next":{"func":"blockLooksSwitchCostume","values":[{"type":"string","value":"blue button off"}]}}}}}

  • {"func":"blockControlBroadcast","values":[{"type":"string","value":"punch"}]}
  • {"func":"blockLooksNextCostume"}
  • {"func":"blockControlWait","values":[{"type":"number","value":".1"}]}
  • {"func":"blockLooksSwitchCostume","values":[{"type":"string","value":"blue button off"}]}

17. What will happen if you make both the blue and orange buttons broadcast the "punch" message?

  • Both the buttons will make the same sound when pressed
  • The "punch" message will no longer work
  • The buttons will still play their original sounds when pressed
  • Neither of the buttons will be able to play sounds anymore
