Programming 101

1. Which of the following blocks is a conditional block?

• {"func":"blockControlIf","values":[{"type":"boolean","value":""}],"containers":[null]}
• {"func":"blockControlForever","containers":[null]}
• {"func":"registerFlagTrigger"}
• {"func":"blockMotionMove","values":[{"type":"number","value":""}]}

2. If {"type":"wrapper","func":"valueVar","name":"isMorning"} is true, what will the Actor with the following code say?
{"func":"blockControlIfElse","values":[{"type":"wrapper","func":"valueVar","name":"isMorning"}],"containers":[{"func":"blockLooksSay","values":[{"type":"string","value":"Hello"}]},{"func":"blockLooksSay","values":[{"type":"string","value":"Goodbye"}]}]}

• Hello
• Goodbye
• Nothing
• HelloGoodbye

3. True or False: Adding a conditional block inside a 'Forever' loop makes the program constantly check whatever's inside the conditional block. For example, in the code shown below, the statement {"type":"wrapper","func":"valueVar","name":"isOffStage"} is constantly checked.
{"func":"blockControlForever","containers":[{"func":"blockControlIf","values":[{"type":"wrapper","func":"valueVar","name":"isOffStage"}],"containers":[{"func":"blockMotionMove","values":[{"type":"number","value":"10"}]}]}]}

• True
• False

4. True or False: The value inside a conditional block must return either true or false.

• True
• False

5. What does the following code return?
{"type":"wrapper","func":"valueOpLess","values":[{"type":"string","value":"2"},{"type":"string","value":"10"}]}

• True
• False
• 2
• 10

6. Jenna has a program with a bunch of backgrounds that she switches through. She wants to do something when the 'SpecialScene' background appears. Which block should she use to figure out when this background is being shown?

• {"func":"blockControlIf","values":[{"type":"wrapper","func":"valueOpEqual","values":[{"type":"wrapper","func":"valueLooksBackgroundName"},{"type":"string","value":"SpecialScene"}]}],"containers":[null]}
• {"func":"blockControlIf","values":[{"type":"boolean","value":"true"}],"containers":[null]}
• {"func":"blockControlIf","values":[{"type":"wrapper","func":"valueLooksIsHidden"}],"containers":[null]}
• {"func":"blockLooksNextBackground"}

7. True or False: {"func":"blockControlWaitUntil","values":[{"type":"boolean","value":""}]} is a conditional block, not a loop block.

• True
• False

8. If {"type":"wrapper","func":"valueVar","name":"isCold"} is true, what will the Actor with the following code do?
{"func":"blockControlIf","values":[{"type":"wrapper","func":"valueVar","name":"isCold?"}],"containers":[{"func":"blockLooksSayFor","values":[{"type":"string","value":"Brrr!"},{"type":"number","value":"2"}]}],"next":{"func":"blockLooksSayFor","values":[{"type":"string","value":"Wow"},{"type":"number","value":"2"}]}}

• The Actor will say "Brrr!" for 2 seconds then say "Wow" for 2 seconds
• The Actor will only say "Brrr!" for 2 seconds
• The Actor will only say "Wow" for 2 seconds
• The Actor will not say anything

9. Which of the following is NOT a comparison operator?

• {"type":"wrapper","func":"valueOpRandom","values":[{"type":"number","value":""},{"type":"number","value":""}]}
• {"type":"wrapper","func":"valueOpLess","values":[{"type":"string","value":""},{"type":"string","value":""}]}
• {"type":"wrapper","func":"valueOpGreater","values":[{"type":"string","value":""},{"type":"string","value":""}]}
• {"type":"wrapper","func":"valueOpEqual","values":[{"type":"string","value":""},{"type":"string","value":""}]}

10. If {"type":"wrapper","func":"valueVar","name":"answer"} is false, what will the following code do?
{"func":"blockControlWaitUntil","values":[{"type":"wrapper","func":"valueVar","name":"answer"}]}

• Keep waiting
• Stop waiting
• End the program
• Make all Actors disappear
