Programming 102

1. If the code for an animation contains a {"func":"blockControlWait","values":[{"type":"number","value":""}]} block, what will increasing the parameter in the block do to the animation? (For example, increasing it from .5 to 1)

• Make the animation slower
• Make the animation faster
• This would have no effect on the animation
• Make the animation pause forever

2. If you had an Actor with four Costumes and wanted to repeatedly switch through the Costumes to create an animation, which of the following sets of blocks is important to use?

• {"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"}

3. True or False: Actors automatically bounce and turn around when they hit an edge. You don't need to add any code blocks to make this happen.

• True
• False

4. True or False: Given the code below, increasing the parameter in the 'Move' block to 20 makes the Actor move fewer pixels per second.
{"func":"blockControlForever","containers":[{"func":"blockMotionMove","values":[{"type":"number","value":"10"}],"next":{"func":"blockControlWait","values":[{"type":"number","value":"1"}]}}]}

• True
• False

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

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

6. What is the difference between the {"func":"blockLooksSwitchCostume","values":[{"type":"string","value":""}]} block and the {"func":"blockLooksNextCostume"} block?

• There is no difference; you can choose which one you want to use
• The {"func":"blockLooksSwitchCostume","values":[{"type":"string","value":""}]} block is for the Stage while the {"func":"blockLooksNextCostume"} block is for Actors
• The {"func":"blockLooksSwitchCostume","values":[{"type":"string","value":""}]} block lets you choose which Costume to switch to while the {"func":"blockLooksNextCostume"} block just makes the Actor put on its next Costume
• The {"func":"blockLooksSwitchCostume","values":[{"type":"string","value":""}]} block switches the Costume immediately while the {"func":"blockLooksNextCostume"} block waits 2 seconds and then switches the Costume

7. What does the {"func":"blockControlWait","values":[{"type":"number","value":""}]} block do?

• Pauses the program for however long you specify
• Deletes the Actor
• Waits until the user presses play to start running the program
• Ends the program

8. What kind of loop is a 'Forever' loop?

• Infinite
• Round
• Temporary
• Conditional

9. How do you make an Actor animate (like Codey the troll)?

• Add a bunch of Costumes to the Actor and switch through them quickly
• Drag the Actor around with your mouse
• Draw the Actor and it will automatically update
• None of the above

10. Tessa has an Actor with three Costumes: Costume1, Costume2, and Costume3. Her Actor starts out wearing Costume1. In her program, she uses the {"func":"blockLooksNextCostume"} block once. What Costume will her Actor be wearing at the end?

• Costume1
• Costume2
• Costume3

11. Will has a {"func":"blockMotionMove","values":[{"type":"number","value":"10"}]} block in his Actor's code. It makes the Actor move a little to the right. If he changes the block to {"func":"blockMotionMove","values":[{"type":"number","value":"50"}]}, what will happen?

• The Actor will move further to the right
• Nothing changes
• The Actor won't move at all
• The Actor will play a sound

12. How do you make an Actor animate and move across the Stage at the same time?

• Do the animation by switching Costumes, and use a 'Move' block to move across the Stage
• You cannot do this
• Use a 'Move' block and the Costumes will automatically change
• Switch Costumes and the Actor will automatically move
