Coding with Minecraft 3: Coordinates

LESSON A: Introduction to Coordinates

WHAT WE’LL LEARN

The difference between relative coordinates and absolute coordinates in

WHY ARE COORDINATES IMPORTANT?

To know the location of:

COORDINATES

Tell a program where an action should take place
A 3-dimensional position

A HANDY TIP

Use this to remember X, Y, Z axes

ABSOLUTE WORLD POSITION

Based on distance from the world origin
Minecraft world origin:

RELATIVE PLAYER POSITION

Based on the player’s current position
Player’s current position is

TO CALCULATE RELATIVE POSITION

IN REAL LIFE

The earth’s geographical origin point, Null Island is at

LET’S DISCUSS

What are the values for X, Y, Z for the

CODE WITH COORDINATES

Create a compass rose
Use relative player positions
Point to the

LESSON B: Coding with Coordinates

Pretend our classroom is a Minecraft world to calculate relative and

REVIEW COORDINATES

What’s absolute world position?
What’s relative player position?
