Programming 101

1. Ashley's brother is graduating from high school and she wants to make him a card. She wants the card to say "Congratulations!" on the front, but have a different message on the inside. Which event block can she use to change the message when the card is open vs. closed? (Select all answers that apply)

• {"func":"registerFlagTrigger"}
• {"func":"registerBackgroundChange","values":[{"type":"string","value":""}]}
• {"func":"registerBroadcastTrigger","values":[{"type":"string","value":""}]}
• {"func":"blockLooksChangeEffect","values":[{"type":"choice","value":"color"},{"type":"number","value":"25"}]}

2. Tom wants to make a message on the Stage blink on and off. He adds the code shown below. What will happen when he runs the program?
{"func":"registerFlagTrigger","next":{"func":"blockControlForever","containers":[{"func":"blockLooksShow","next":{"func":"blockLooksHide","next":{"func":"blockControlWait","values":[{"type":"number","value":".5"}]}}}]}}

• The message will blink: it will appear for .5 seconds, then hide for .5 seconds over and over
• The message will not appear at all
• The message will appear but will not blink; it will just stay on the screen
• The message will disappear for .5 seconds and then show up and stay on the Stage without ever disappearing again

3. True or False: The {"func":"blockLooksHide"} block permanently deletes the Actor from the program.

• True
• False

4. True or False: To make an Actor disappear when you click on it, you can use the following code.
{"func":"registerSpriteTrigger","next":{"func":"blockLooksHide"}}

• True
• False

5. Jack added a blue background to the Stage and the code shown below. What color will the Stage be when the program finishes running?
{"func":"registerFlagTrigger","next":{"func":"blockLooksChangeEffect","values":[{"type":"choice","value":"color"},{"type":"number","value":"25"}],"next":{"func":"blockLooksClearEffects"}}}

• Blue
• Purple
• Green
• Yellow

6. You will often put a {"func":"blockLooksClearEffects"} block under {"func":"registerFlagTrigger"} to reset the graphic changes you make during your program. If your program only makes color changes, which of the following blocks can you replace {"func":"blockLooksClearEffects"} with?

• {"func":"blockLooksSetEffect","values":[{"type":"choice","value":"color"},{"type":"number","value":"0"}]}
• {"func":"blockLooksNextBackground"}
• {"func":"blockLooksChangeEffect","values":[{"type":"choice","value":"color"},{"type":"number","value":"-100"}]}
• {"func":"blockControlWait","values":[{"type":"number","value":"1"}]}

7. How would you set up a program for a card that opens when you click on it? (Select all answers that apply)

• Add an Actor and give it two Costumes, one for the opened card and one for the closed card
• Add a second background to the Stage so you have one background for open and one for closed
• Add an Actor with one Costume for the open card
• Add two Actors, one for the opened card and one for the closed card

8. What code would you use to make a card that plays music when you click on it?

• {"func":"registerSpriteTrigger","next":{"func":"blockSoundPlay","values":[{"type":"string","value":""}]}}
• {"func":"registerFlagTrigger","next":{"func":"blockSoundPlay","values":[{"type":"string","value":""}]}}
• {"func":"registerSpriteTrigger","next":{"func":"blockLooksNextCostume"}}
• {"func":"registerSpriteTrigger","next":{"func":"blockSoundStopAll"}}

9. How do you make an Actor show up after it has been hiding for awhile?

• Use the {"func":"blockLooksShow"} block
• Add the Actor again
• You can't; once it's been hiding, it never comes back
• Click on it

10. True or False: To make an Actor disappear when you tap on it, you can use the following code.
{"func":"registerSpriteTrigger","next":{"func":"blockLooksHide"}}

• True
• False

11. How would you set up a program for a card that opens when you tap on it? (Select all answers that apply)

• Add an Actor and give it two Costumes, one for the opened card and one for the closed card
• Add a second background to the Stage so you have one background for open and one for closed
• Add an Actor with one Costume for the open card
• Add two Actors, one for the opened card and one for the closed card

12. What code would you use to make a card that plays music when you tap on it?

• {"func":"registerSpriteTrigger","next":{"func":"blockSoundPlay","values":[{"type":"string","value":""}]}}
• {"func":"registerFlagTrigger","next":{"func":"blockSoundPlay","values":[{"type":"string","value":""}]}}
• {"func":"registerSpriteTrigger","next":{"func":"blockLooksNextCostume"}}
• {"func":"registerSpriteTrigger","next":{"func":"blockSoundStopAll"}}
