Variables in Minecraft

Step 1

Variables are pieces of information we tell the computer to store

They can be:
  • set - assigned a value
  • read - use the value inside them

Step 2
Create a message variable

A variable is created by using the var keyword and giving it a name

Step 3
Assign a value to your variable

We assign a value to a variable by using an = between the variable and value;

The variable being assigned a value goes to the left

The value goes to the right

Step 4
