Lesson 3 - Coding with Minecraft - Variables.pptx
- 1. Coding with Minecraft 4: Variables
- 3. The importance of variables The different kinds of variables To code a game in Minecraft with variables
- 4. Number variable This holds numeric data. Examples: a persons age, a players score, the year String variable This holds a string of alphanumeric characters. Examples: a persons name, a password, the day of the week Boolean variable This has only two possible values: true or false. Examples: Is it daytime? Is the game over? Position variable in MakeCode A special kind of variable that holds three numbers that describe a specific location in three-dimensional space.
- 7. CHALLENGE 1 - MEANINGFUL VARIABLE NAMES Lets change the code so we are not using num1 The name num1 does not represent anything meaningful and could be hard to understand a big block of code. Instead, name your new variable ChickenNum because the number you store is the number of chickens.
- 8. CHALLENGE 2 - GIVING FEEDBACK Lets have the chicken rain machine speak back to you. Right before you the chickens start falling the response would be 5 Chickens! Coming right up! Then 5 chickens will fall on your head!
- 9. CHALLENGE 2 - GIVING FEEDBACK To do this, you will need to 1. Figure out how to say things in the chat window 2. Use the join block to put together ChickenNum + chickens! Coming right up! 3. Put this new block in the right location in your code. If you put it in the wrong spot, the chat window will respond many times
- 10. CHALLENGE 2 - GIVING FEEDBACK
- 11. REVIEW What did your variable determine in the game? Why is it good coding practice to give variables meaningful names?
- 13. To code variables in Minecraft to: Count things Keep score Create a report of your games activities
- 14. ARROW COUNTER
- 15. ARROW COUNTER
- 16. CHALLENGE 1 - 10 ARROWS ONLINE
- 17. CHALLENGE 2 - PROVIDING A MESSAGE
- 19. EXTENSION 2- HOW MANY RABBITS?
- 20. FALLS IN THE AIR
- 21. FALLS IN THE AIR - STEP 1
- 22. FALLS IN THE AIR - STEP 2
- 23. HOW DOES THE VARIABLE WORK?
- 24. EXTENSION 1 - TRACK SWIM DISTANCE
- 25. To use variables in Minecraft to: Count things Keep score Create a report of your games activities
- 26. LESSON C : COMBINING VARIABLES
- 27. Combining variables to create messages in the sky Check our learning progress with a quiz
- 28. Make your own unique situations Combine the variables to create chains of words Create a variable that stands for a word
- 31. To create your own MakeCode projects that use variables to activate different parts of your program
- 32. INDEPENDENT PROJECT For this project, create an original MakeCode project that uses multiple variables of at least two different types, to keep track of information in Minecraft. Also, find a way to use a chat command with a parameter.
- 33. INDEPENDENT PROJECT Information you might store in variables / project ideas: Store the number of something you spawn Store text for the animal you spawned Store your position Store words to put together to make sentences.
- 34. MINECRAFT DIARY ENTRY What type of information did you choose to keep track of? What problems did you encounter? How did you solve them? How did you use variables in your project, and what were their types? What did you name your variables and why? What was something new that you learned for this project? Describe how you figured it out. Include at least one screenshot of your project.
