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":""}]}

  • up arrow
  • a
  • enter
  • All of these keys can be used as values inside the When Key Pressed block

5. What does this code block do? {"func":"registerKeyTrigger","values":[{"type":"choice","value":"space"}],"next":{"func":"blockLooksNextCostume"}}

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

  • When the Play button is pressed, the music will play once
  • When the up arrow is pressed, the music will play forever
  • When the spacebar is pressed, the music will play forever

9. Nancy wants to design a game where the Actors hide when the player finds them with the mouse cursor. Which code blocks can help her do this?

  • {"func":"registerFlagTrigger","next":{"func":"blockControlForever","containers":[{"func":"blockControlIfElse","values":[{"type":"wrapper","func":"valueSensingTouchingSprite","values":[{"type":"string","value":"mouse-pointer"}]}],"containers":[{"func":"blockLooksShow"},{"func":"blockLooksHide"}]}]}}

12. What is the difference between the {"func":"blockMotionMove","values":[{"type":"number","value":"10"}]} and {"func":"blockMotionMove","values":[{"type":"number","value":"-10"}]} blocks?

  • 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
  • The {"func":"blockMotionMove","values":[{"type":"number","value":"10"}]} block changes the position of the Actor based on its coordinate position, while the {"func":"blockMotionMove","values":[{"type":"number","value":"-10"}]} block changes position based on its direction

  • When the Play button is pressed, the Actor will change to the next Costume
  • When the device is tilted forward, the Actor will change to the next Costume
  • When the screen is tapped, the Actor will change to a specific Costume

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

  • The Actor will change Costumes when the Play button is pressed, rather than when the screen is tapped.
  • The Actor will change Costumes when the screen is tapped, rather than when the Play button is pressed.

Key stage 3
Pupils should be taught to:
  • design, use and evaluate computational abstractions that model the state and behaviour of real-world problems and physical systems
  • understand several key algorithms that reflect computational thinking [for example, ones for sorting and searching]; use logical reasoning to compare the utility of alternative algorithms for the same problem
  • undertake creative projects that involve selecting, using, and combining multiple applications, preferably across a range of devices, to achieve challenging goals, including collecting and analysing data and meeting the needs of known users
  • create, reuse, revise and repurpose digital artefacts for a given audience, with attention to trustworthiness, design and usability
  • understand a range of ways to use technology safely, respectfully, responsibly and securely, including protecting their online identity and privacy; recognise inappropriate content, contact and conduct, and know how to report concerns
Key stage 4
Pupils should be taught to:
  • develop their capability, creativity and knowledge in computer science, digital media and information technology
  • develop and apply their analytic, problem-solving, design, and computational thinking skills
  • understand how changes in technology affect safety, including new ways to protect their online privacy and identity, and how to report a range of concerns

In Dragon Attack, they define multiple levels and lives, and program a boss enemy, while learning about variables and cloning.

Topics

  • Events
  • Keyboard and mouse interaction
  • Conditional loops
  • Nested loops
  • Sending and receiving messages
  • Fluid motion
  • Parallax scrolling
  • Local and global variables
  • Functions
  • Object cloning
