Programming 201

1. What is the starting block for any program?

• {"func":"registerFlagTrigger"}
• {"func":"blockControlForever","containers":[null]}
• {"func":"blockControlWait","values":[{"type":"number","value":"1"}]}
• {"func":"blockLooksNextCostume"}

2. How do you add a background to the Stage?

• Click the gear icon on the Stage and click the "Add Background" button
• Double-click on the Stage and click the "Add Background" button
• All of the above
• None of the above

3. How many costumes can you add to an Actor?

• An Actor can only have one costume
• An Actor can have up to five costumes
• Some Actors can have five, but others can have up to 10
• An Actor can have as many costumes as you want

4. How do you make an animation faster?

• You decrease the number of next costume blocks
• You increase the number in the 'Wait' block, so you wait less time to switch to the next costume
• You decrease the number in the 'Wait' block, so you wait less time to switch to the next costume
• You use two 'Forever' blocks

5. How do you delete a code block?

• Disconnect the code block from all other blocks
• You can't delete code blocks
• Drag it back to the code palette, which will show a trash can icon
• Save your project

6. How do you get a code block to run AFTER another code block?

• You can't control when your code blocks run
• You connect it underneath the other code block
• You connect it above the other code block
• You put it in another Actor's code

7. How long does a 'Forever' block run?

• Once
• 10 times
• A 'Forever' loop repeats code blocks inside it over and over until the program ends
• A 'Forever' loop repeats code blocks inside it over and over even after the program ends

8. Which of the following code blocks is a loop block?

• {"func":"registerFlagTrigger"}
• {"func":"blockControlForever","containers":[null]}
• {"func":"blockLooksNextCostume"}
• {"func":"blockControlWait","values":[{"type":"number","value":"1"}]}

9. Which of these actions would be the same as removing the 'Wait' block?

• Removing the 'Forever' block
• Setting the 'Wait' value to 0
• Removing the 'Next Costume' block
• Setting the 'Wait' value to 10

10. True or False: Your program won't run without using the 'On Start' code block at least once.

• True
• False

11. What will the following code do to an Actor?
{"func":"registerFlagTrigger","next":{"func":"blockLooksNextCostume"}}

• Nothing will happen to the Actor
• The Actor will change costumes each time the Play button is clicked
• An animation will play
• The Actor will change costumes each time the spacebar is pressed

12. True or False: The following code blocks will animate an Actor that has multiple Costumes.
{"func":"registerFlagTrigger","next":{"func":"blockControlForever","containers":[{"func":"blockLooksNextCostume","next":{"func":"blockControlWait","values":[{"type":"number","value":".5"}]}}]}}

• True
• False

13. What is the difference between these two sets of code?

{"func":"registerFlagTrigger","next":{"func":"blockControlForever","containers":[{"func":"blockLooksNextCostume"}]}} {"func":"registerFlagTrigger","next":{"func":"blockControlForever","containers":[{"func":"blockLooksNextCostume","next":{"func":"blockControlWait","values":[{"type":"number","value":".5"}]}}]}}

• The first one will play the animation extremely quickly while the second one will play the animation more slowly and look more natural
• The first one only works for Actors with multiple costumes while the second one works for all Actors
• They are the same, and the added 'Wait' block doesn't change anything
• The first one loops through all of the costumes while the second one will only loop through the first two costumes

14. What block(s) should you use to make an Actor constantly animated while the program is running?

• {"func":"blockControlForever","containers":[null]}
• {"func":"blockControlWait","values":[{"type":"number","value":"1"}]}
• {"func":"blockLooksNextCostume"}
• All of the above
• None of the above

15. True or False: To add costumes to an Actor, click the gear on the Stage and click the "Add Background" button.

• True
• False

16. Which block is used to play sounds in your project?

• {"func":"blockSoundPlayUntilDone","values":[{"type":"string","value":""}]}
• {"func":"registerFlagTrigger"}
• {"func":"blockLooksNextCostume"}
• {"func":"blockControlForever","containers":[null]}

17. What happens when you leave the parameter in the 'Play Sound Until Done' block blank?
{"func":"blockSoundPlayUntilDone","values":[{"type":"string","value":""}]}

• It will not play any Sounds
• It will automatically play the first Sound found in your project
• It will randomly pick a Sound to play
• It will play the 'yip' Sound by default

18. Kevin wants to add background music to his project. Which set of code will help him do that?

• {"func":"registerFlagTrigger","next":{"func":"blockControlForever","containers":[{"func":"blockSoundPlayUntilDone","values":[{"type":"string","value":"bg music"}]}]}}
• {"func":"registerFlagTrigger","next":{"func":"blockControlForever","containers":[{"func":"blockLooksNextCostume"}]}}
• {"func":"registerFlagTrigger","next":{"func":"blockControlForever","containers":[{"func":"blockLooksNextCostume","next":{"func":"blockControlWait","values":[{"type":"number","value":".1"}]}}]}}
• {"func":"registerFlagTrigger","next":{"func":"blockControlForever","containers":[{"func":"blockControlWait","values":[{"type":"number","value":".1"}]}]}}

19. Laura wants to animate Pixel to dance to the music. How can she do this?

• Laura should use the 'Wait' and 'Next Costume' blocks in Pixel's code to time the costume changes to go with the beat of the music
• Laura should set the music to play at different times
• Laura does not need to do anything since Pixel will automatically dance when music is played

20. How many Actors can you animate at once?

• As many as you want
• Only 5 Actors can be animated on the Stage at any given time
• Only one Actor at a time
• You cannot animate Actors

21. How do you add a background to the Stage?

• Double-tap the Stage, tap "Properties", and tap "Add Background"
• All of the above
• None of the above

22. What will the following code do to an Actor?
{"func":"registerFlagTrigger","next":{"func":"blockLooksNextCostume"}}

• Nothing happens to the Actor
• The Actor will change costumes each time the Play button is touched
• An animation will play
• The Actor will change costumes each time the user touches the screen

23. True or False: To add costumes to an Actor, open the Properties on the Stage and tap the "Add Background" button.
