Programming 101

1. What is one way to make a still copy of an Actor?

• {"func":"blockPenStamp"}
• {"func":"registerSpriteTrigger","next":{"func":"blockLooksShow"}}
• {"func":"blockControlForever","containers":[{"func":"blockLooksShow"}]}
• {"func":"blockMotionPointTowards","values":[{"type":"string","value":"self"}],"next":{"func":"blockMotionMove","values":[{"type":"number","value":"10"}]}}

2. David wants to make a stamp machine program. He has an Actor with two Costumes. When the user clicks on the Actor, he wants the Actor's Costume to change. When the user presses the spacebar, he wants the Actor to stamp on the Stage. He should use the ___ event block for changing Costumes and the ___ event block for stamping.

• {"func":"registerSpriteTrigger"}, {"func":"registerKeyTrigger","values":[{"type":"choice","value":"space"}]}
• {"func":"registerFlagTrigger"}, {"func":"registerSpriteTrigger"}
• {"func":"registerBroadcastTrigger","values":[{"type":"string","value":""}]}, {"func":"registerFlagTrigger"}
• {"func":"registerKeyTrigger","values":[{"type":"choice","value":"space"}]}, {"func":"registerKeyTrigger","values":[{"type":"choice","value":"space"}]}

3. Megan is making a stamp machine program like the one you just made. She has a Smiley Face Actor with two Costumes: one for a normal smiley face, one for when the smiley face is being stamped down. What two blocks should go below {"func":"registerSpriteTrigger"} so that she both stamps an image of the Actor on the Stage and changes the Actor's Costume?

• {"func":"blockPenStamp","next":{"func":"blockLooksNextCostume"}}
• {"func":"blockPenStamp","next":{"func":"blockMotionMove","values":[{"type":"number","value":"10"}]}}
• {"func":"blockLooksNextCostume","next":{"func":"blockLooksShow"}}
• {"func":"blockLooksNextCostume","next":{"func":"blockLooksHide"}}

4. What does dragging code blocks into your backpack do?

• Lets you save the blocks to use in other programs
• Deletes the blocks
• Nothing, there is no backpack
• Makes the code blocks run

5. True or False: Colors can be represented by numbers, like #FF8844.

• True
• False

6. Which of the following blocks is not a loop block?

• {"func":"blockPenStamp"}
• {"func":"blockControlForever","containers":[null]}
• {"func":"blockControlRepeat","values":[{"type":"number","value":"10"}],"containers":[null]}
• {"func":"blockControlRepeat","values":[{"type":"number","value":"20"}],"containers":[null]}

7. Jenny has added the code shown below. What happens if you change the parameter of the 'Repeat' block to 20 instead of 10?
{"func":"blockControlRepeat","values":[{"type":"number","value":"10"}],"containers":[{"func":"blockPenStamp"}]}

• You will now stamp 20 times instead of 10
• Nothing changes
• You will not stamp anymore
• You will never stop stamping

8. To start drawing, which of the following blocks do you need?

• {"func":"blockPenDown"}
• {"func":"blockPenSetFont","values":[{"type":"choice","value":""},{"type":"choice","value":""},{"type":"choice","value":""}]}
• {"func":"blockMotionMove","values":[{"type":"number","value":""}]}
• {"func":"blockControlForever","containers":[null]}

9. True or False: The {"func":"blockPenDown"} block makes the pen trace the path of the current Actor.

• True
• False

10. Megan is making a stamp machine program like the one you just made. She has a Smiley Face Actor with two Costumes: one for a normal smiley face, one for when the smiley face is being stamped down. What two blocks should go below {"func":"registerSpriteTrigger"} so that she both stamps an image of the Actor on the Stage and changes the Actor's Costume?

• {"func":"blockPenStamp","next":{"func":"blockLooksNextCostume"}}
• {"func":"blockPenStamp","next":{"func":"blockMotionMove","values":[{"type":"number","value":"10"}]}}
• {"func":"blockLooksNextCostume","next":{"func":"blockLooksShow"}}
• {"func":"blockLooksNextCostume","next":{"func":"blockLooksHide"}}
