1. Which of these two turn blocks are equivalent? (Choose 2.)

  • {"func":"blockMotionTurnCW","values":[{"type":"string","value":"180"}]}
  • {"func":"blockMotionTurnCCW","values":[{"type":"string","value":"180"}]}
  • {"func":"blockMotionTurnCW","values":[{"type":"string","value":"90"}]}
  • {"func":"blockMotionTurnCCW","values":[{"type":"string","value":"90"}]}

2. What is the difference between the {"func":"blockMotionTurnCW","values":[{"type":"string","value":"90"}]} and {"func":"blockMotionPointDirection","values":[{"type":"string","value":"90"}]} blocks?

  • The {"func":"blockMotionTurnCW","values":[{"type":"string","value":"90"}]} block changes the actor relative to its current direction, while the {"func":"blockMotionPointDirection","values":[{"type":"string","value":"90"}]} block is not dependent on the current direction of the actor
  • The {"func":"blockMotionTurnCW","values":[{"type":"string","value":"90"}]} block is not dependent on the current direction of the actor, while the {"func":"blockMotionPointDirection","values":[{"type":"string","value":"90"}]} block changes the actor relative to its current direction
  • Both the {"func":"blockMotionTurnCW","values":[{"type":"string","value":"90"}]} and {"func":"blockMotionPointDirection","values":[{"type":"string","value":"90"}]} blocks change the actor relative to its current direction
  • Both the {"func":"blockMotionTurnCW","values":[{"type":"string","value":"90"}]} and {"func":"blockMotionPointDirection","values":[{"type":"string","value":"90"}]} blocks are not dependent on the current direction of the actor

3. What does this code block do? {"func":"registerFlagTrigger","next":{"func":"blockMotionGoTo","values":[{"type":"number","value":"0"},{"type":"number","value":"0"}],"next":{"func":"blockMotionPointDirection","values":[{"type":"wrapper","func":"valueOpRandom","values":[{"type":"number","value":"1"},{"type":"number","value":"360"}]}],"next":{"func":"blockControlForever","containers":[{"func":"blockMotionMove","values":[{"type":"number","value":"10"}],"next":{"func":"blockControlWait","values":[{"type":"number","value":".5"}]}}]}}}}

  • The Actor will start off in the center of the screen and move forever in a random direction
  • The Actor will start off in the center of the screen and move to the right forever
  • The Actor will start in a random location and move forever in a random direction
  • The Actor will start off in the center of the screen and not move

Key stage 2
Pupils should be taught to:
  • design, write and debug programs that accomplish specific goals, including controlling or simulating physical systems; solve problems by decomposing them into smaller parts
  • use sequence, selection, and repetition in programs; work with variables and various forms of input and output

  • understand computer networks, including the internet; how they can provide multiple services, such as the World Wide Web, and the opportunities they offer for communication and collaboration
  • use search technologies effectively, appreciate how results are selected and ranked, and be discerning in evaluating digital content
  • select, use and combine a variety of software (including internet services) on a range of digital devices to design and create a range of programs, systems and content that accomplish given goals, including collecting, analysing, evaluating and presenting data and information
  • use technology safely, respectfully and responsibly; recognise acceptable/unacceptable behaviour; identify a range of ways to report concerns about content and contact

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
  • Advanced events
