Module 11: Quiz

1. What would happen if we changed the Point in Direction value from 90 to -90? {"func":"blockMotionPointDirection","hiddenInSandbox":false,"values":[{"type":"string","value":"90"}],"next":{"func":"blockMotionMove","values":[{"type":"number","value":"10"}]}}

  • The Actor will move left instead of right
  • The Actor will move up instead of right
  • The Actor will move down instead of right
  • The Actor will still move right

2. What value belongs in the Point in Direction block if we want the Actor to face up? {"func":"blockMotionPointDirection","values":[{"type":"string","value":""}]}

  • 0
  • 90
  • -90
  • 180

3. True or False: The direction that the Actor moves using the Move block depends on the direction the Actor is pointing in. {"func":"blockMotionMove","values":[{"type":"number","value":"10"}]}

  • True
  • False

4. Which of these keys can be used with the When Key Pressed block? {"func":"registerKeyTrigger","values":[{"type":"choice","value":""}]}

6. What will happen if we replace {"func":"registerKeyTrigger","values":[{"type":"choice","value":"space"}]} with {"func":"registerFlagTrigger"} in this code block? {"func":"registerKeyTrigger","values":[{"type":"choice","value":"space"}],"next":{"func":"blockLooksNextCostume"}}

  • The Actor will change Costumes when the Play button is pressed, rather than when the spacebar is pressed.
  • The Actor will change Costumes when the spacebar is pressed, rather than when the Play button is pressed.
  • The Actor will change Costumes when the up arrow is pressed.
  • The Actor will disappear when the spacebar is pressed.

7. What happens if we change the value in the When Key Pressed block from right arrow to left arrow? {"func":"registerKeyTrigger","values":[{"type":"choice","value":"right arrow"}],"next":{"func":"blockMotionPointDirection","hiddenInSandbox":false,"values":[{"type":"string","value":"90"}],"next":{"func":"blockMotionMove","values":[{"type":"number","value":"10"}]}}}

  • The Actor would move right when you held the left arrow

  • Both of the blocks change the position of the Actor based on its direction, but the {"func":"blockMotionMove","values":[{"type":"number","value":"10"}]} block moves the actor forwards while the {"func":"blockMotionMove","values":[{"type":"number","value":"-10"}]} moves the actor backwards.
  • The {"func":"blockMotionMove","values":[{"type":"number","value":"10"}]} block changes the position of the Actor based on its direction, while the {"func":"blockMotionMove","values":[{"type":"number","value":"-10"}]} block changes position based on its coordinate position

Advance your class to intermediate level programming concepts using a wider set of visual blocks. In Snowball Siege, students learn about layering, Actor visibiliy, motion, and collisions. Then, in Star Runner, they use line drawing commands and program math art. They build several mini-games while understanding how to create more complex programs. After completing this lesson plan, students will be able to build a wide variety of school projects and their own comprehensive games.

Topics

  • Animation sequences
  • Motion
  • Game design basics
  • Built-in animation commands
  • Advanced keyboard and mouse control
  • Sending and receiving messages
  • Actor layering
