Module 9: Quiz

1. What does this do? {"func":"registerSpriteTrigger","next":{"func":"blockLooksHide"}}

  • The Actor dances on its head when the program is played.
  • The Actor disappears when clicked.
  • The Actor appears in a random location on the screen.
  • The Actor appears in another project.

2. Why does the Actor not appear after the following block of code? {"func":"registerSpriteTrigger","next":{"func":"blockLooksHide"}}

  • That's the function of the Hide block.
  • The When Actor Clicked block always makes Actors disappear.
  • The code is missing an On Start block.
  • The Actor will not disappear with this code block.

3. What will this block of code do? {"func":"blockControlForever","containers":[{"func":"blockMotionGoTo","values":[{"type":"number","value":"0"},{"type":"wrapper","func":"valueOpRandom","values":[{"type":"wrapper","func":"valueSensingScreenBottom"},{"type":"wrapper","func":"valueSensingScreenTop"}]}],"next":{"func":"blockControlWait","values":[{"type":"number","value":"1"}]}}]}

  • This will make the Actor move to different locations, as long as the x position is 0
  • This will make the Actor move to different locations, as long as the x position is not the same
  • This will make the Actor move to different locations as long as the y position is 0
  • This is will make the Actor stay in the same location

4. Why must we wait a few seconds after hiding an Actor before showing it again?

  • The Actor will disappear forever and not return again no matter what you do if you do not wait a few seconds between the actions.
  • We would not be able to add other Actors if we do not wait a few seconds between the actions.
  • The actions will happen too fast for our eyes to see if we don't wait for a few seconds between the actions.
  • There is no use in waiting a few seconds after hiding an Actor and before showing it.

5. What block of code will make the Actor appear in random locations all over the screen every few seconds?

  • {"func":"registerFlagTrigger","next":{"func":"blockLooksShow"}}
  • {"func":"registerFlagTrigger","next":{"func":"blockControlForever","containers":[{"func":"blockMotionGoTo","values":[{"type":"wrapper","func":"valueSensingScreenLeft"},{"type":"number","value":"0"}],"next":{"func":"blockControlWait","values":[{"type":"wrapper","func":"valueOpRandom","values":[{"type":"number","value":"1"},{"type":"number","value":"10"}]}]}}]}}
  • {"func":"registerFlagTrigger","next":{"func":"blockControlForever","containers":[{"func":"blockControlWait","values":[{"type":"wrapper","func":"valueOpRandom","values":[{"type":"number","value":"1"},{"type":"number","value":"10"}]}]}]}}
  • {"func":"registerFlagTrigger","next":{"func":"blockControlForever","containers":[{"func":"blockMotionGoTo","values":[{"type":"wrapper","func":"valueOpRandom","values":[{"type":"wrapper","func":"valueSensingScreenLeft"},{"type":"wrapper","func":"valueSensingScreenRight"}]},{"type":"wrapper","func":"valueOpRandom","values":[{"type":"wrapper","func":"valueSensingScreenBottom"},{"type":"wrapper","func":"valueSensingScreenTop"}]}],"next":{"func":"blockControlWait","values":[{"type":"wrapper","func":"valueOpRandom","values":[{"type":"number","value":"1"},{"type":"number","value":"10"}]}]}}]}}

6. True or False: You can send all Actors to random locations using {"func":"blockMotionGoTo","values":[{"type":"wrapper","func":"valueOpRandom","values":[{"type":"wrapper","func":"valueSensingScreenLeft"},{"type":"wrapper","func":"valueSensingScreenRight"}]},{"type":"wrapper","func":"valueOpRandom","values":[{"type":"wrapper","func":"valueSensingScreenBottom"},{"type":"wrapper","func":"valueSensingScreenTop"}]}]}

  • True
  • False

7. True or False: You can tell another Actor to hide by broadcasting messages.

  • True
  • False

8. True or False: {"func":"registerSpriteTrigger"} can react to other kinds of events other than mouse clicks, such as key presses.

  • True
  • False

9. True or False: The blocks {"func":"blockLooksShow"} and {"func":"blockLooksHide"} can only be used with {"func":"registerSpriteTrigger"}

  • True
  • False

10. True or False: Multiple Actors can {"func":"blockLooksShow"} and {"func":"blockLooksHide"} at the same time.

  • True
  • False

11. True or False: One Actor can make another hide or show by broadcasting messages.

  • True
  • False

12. True or False: One Actor can make another go to a random location without using the {"func":"blockControlBroadcast","values":[{"type":"string","value":""}]} and {"func":"registerBroadcastTrigger","values":[{"type":"string","value":""}]}

  • True
  • False

13. Which of the following blocks of code makes the Actor stay in the same place? There may be more than 1 answer.

  • {"func":"registerFlagTrigger","next":{"func":"blockControlForever","containers":[{"func":"blockMotionGoTo","values":[{"type":"wrapper","func":"valueSensingScreenLeft"},{"type":"number","value":"0"}],"next":{"func":"blockControlWait","values":[{"type":"wrapper","func":"valueOpRandom","values":[{"type":"number","value":"1"},{"type":"number","value":"10"}]}]}}]}}
  • {"func":"registerFlagTrigger","next":{"func":"blockControlForever","containers":[{"func":"blockMotionGoTo","values":[{"type":"wrapper","func":"valueOpRandom","values":[{"type":"wrapper","func":"valueSensingScreenLeft"},{"type":"wrapper","func":"valueSensingScreenRight"}]},{"type":"wrapper","func":"valueOpRandom","values":[{"type":"wrapper","func":"valueSensingScreenBottom"},{"type":"wrapper","func":"valueSensingScreenTop"}]}],"next":{"func":"blockControlWait","values":[{"type":"wrapper","func":"valueOpRandom","values":[{"type":"number","value":"1"},{"type":"number","value":"10"}]}]}}]}}
  • {"func":"registerFlagTrigger","next":{"func":"blockControlForever","containers":[{"func":"blockMotionGoTo","values":[{"type":"number","value":"0"},{"type":"wrapper","func":"valueOpRandom","values":[{"type":"wrapper","func":"valueSensingScreenBottom"},{"type":"wrapper","func":"valueSensingScreenTop"}]}],"next":{"func":"blockControlWait","values":[{"type":"wrapper","func":"valueOpRandom","values":[{"type":"number","value":"1"},{"type":"number","value":"10"}]}]}}]}}
  • {"func":"registerFlagTrigger","next":{"func":"blockControlForever","containers":[{"func":"blockMotionGoTo","values":[{"type":"number","value":"0"},{"type":"number","value":"0"}],"next":{"func":"blockControlWait","values":[{"type":"wrapper","func":"valueOpRandom","values":[{"type":"number","value":"1"},{"type":"number","value":"10"}]}]}}]}}

14. True or False: {"type":"wrapper","func":"valueOpRandom","values":[{"type":"number","value":"1"},{"type":"number","value":"10"}]} will give a number that is between 1 and 10, but not including 1 or 10.

  • True
  • False

15. What does this do? {"func":"registerSpriteTrigger","next":{"func":"blockLooksHide"}}

  • The Actor dances on its head when the program is played.
  • The Actor disappears when tapped.
  • The Actor appears in a random location on the screen.
  • The Actor appears in another project.

16. Why does the Actor not appear after the following block of code? {"func":"registerSpriteTrigger","next":{"func":"blockLooksHide"}}

  • That's the function of the Hide block.
  • The When Actor Clicked block always makes Actors disappear.
  • The code is missing an On Start block.
  • The Actor will not disappear with this code block.

17. True or False: {"func":"registerSpriteTrigger"} can react to other kinds of events other than touching the screen, such as tilting the device.

  • True
  • False
