1. Blockly Minecraft Task 1 ) Please copy the example task. Task by task
Blockly Minecraft Task 1 ) Please copy the example task. Task by task. Do not alter or personalise it in any way.
Drag out the SKYMAP block
Drag out a SKIN block
Then select AGENTSMITH
Press
CTRL & D to bookmark and save your work
Then press
Run X

2. X Adding extra blocks Using the Minecraft blocks
Copy this block pattern
Your blockly character needs a nickname – Call him Agent Smith X
Now- Run the program
Your character takes small steps – try changing the step to 1 – steps are longer – but not realistic
Use right click to quickly create additional blocks so that walking looks more realistic.
What will happen if you use move -0.5?

3. Using arrays Example A Example B A B Program B works slower why?
ReadS the randomly selected phrase from the list
It then replaces the VARIABLE ARRAY list with the phrase (the full list is wiped from memory – replaced by the randomly selected text)
The single phrase in memory is said (printed on screen)
The next loop cycle all the phrases are re-read and the re-written back into the computer memory and stored as a new data for the variable array (LIST). This read write to memory process takes time causing a short delay.
Program A only writes the information to Random Access Memory once it only looks up a random phrase which is already stored therefore the array is not changed in any way this is faster.
Program A might need a delay or a steeping loop to slow it down so that it is more user friendly - readable. Program B is very efficient and fast. Program A works fine and is easy to read.
There are often several ways to achieve the same outcome. Generally programs need to be very efficient and reponsive ie.fast.
Program B works slower why?

4. Using variables – creating an array!
Drag in this VARIABLE block
Give the variable a name
Drag in this list block
Drag in this minecraft block
Duplicate it so that you have three copies. Add text phrases

5. Variables are usually defined at the start of a program
Drag and connect the quotes variable to the start of the program.
A variable which stores several distinct pieces of data is called an ARRAY.
This array is in the form of a list. X
RAM
CHIP
If you press run – the array will not do anything. The data is simply stored in a memory location inside the computers RAM memory chip.

6. Lets create a path for Agent smith to walk
Drag a loop block from the control menu
Your program should look like this!
Set the loop to run 8 times
Use 108 degrees
Press
CTRL & D to bookmark and save your work
Then press
Run
Run the program to test it X

7. Make your character talk
Drag and connect these communication blocks from the Minecraft fly out option menu
Type in Hello, World!
This is a tradition that all programmers follow
When you learn a new programming language Print(“Hello, World!) is usually your first step.
Press
CTRL & D to bookmark and save your work
Then press
Run X

8. Lets use the data array - Quotes
Drag and connect this communication block from the Minecraft fly out option menu
Drag and connect this Lists block
This command will pick RANDOM quotes from the data array and your character will say them on screen

9. Putting it all together
Agent Smith will now walk and talk randomly. E.g. b c a c b

10. Research
Lets google search and find some cool phrases!

11. No delay block!
No problem!
Lets make one using a stepping loop

12. Going random Make Agent Smith unpredictable
Using random numbers in a loop creates interest.
Make Agent Smith dance
Using random walks
-numbers walk backwards
+numbers walk forwards

13. Task 2
Document your program. Like this. Use this example or the template provided.
Task 3) Choose a different character.
E.g. Mario
Use the www to research his quotes.
Test and document your program.
