In this lesson, we’ll explore the concept of a variable, an important way to store information and make your programs more flexible and adaptable. We’ll build on what we have learned about Events by using a variable to pass additional information in when an event occurs.
• Explain the importance of variables in coding and while playing Minecraft • Design an original project to apply the use of variables to create an automated solution
Variables have a name, a type, and a value: name - how you’ll refer to the variable. type - the kind of data a variable will store. value - what’s stored (the data) in the variable. You can use the default variable names given in the blocks if you’d like. However, it’s best to use descriptive variable names.
Variables: what is dirty, what is clean, what I want to buy, number of shoes, number of socks, etc. Each variable holds a specific type of information. The first time you use a variable, you set its type. From that point on, you can store only information of that type in that variable.
What is a variable. A variable is a value that holds data like states or numbers or even words for later use. They are useful when needing to test if something is happening or if a word is the same as something else, they can also be used in math to test for number values.
Variables are used as place holders for pieces of text (strings), numerical values, commands, and even other variables. A variable inside a piece of code is replaced by a number or text when the code is run. You can think of a variable as a box that contains something (a number or text).
