Functions Blocks

Function Overview
A function is a block of code that performs a specific task. If you use the same code set multiple times in your project, you can work more efficiently using functions. Clear function names also make your code more readable.

Create a function
You can use the following block to create a function and give it a name:
One example of a function is below. This function will create and shuffle a list of items.
After you have created your function, you can simply use it at any time using the function block you have named:
Create a function with an output
You can also create a function that returns a specific output.
Conditional Outputs
You can add multiple return blocks to your function. This allows you to return a different output based on some conditions.
For example, this function will take a rating out of 100, and return a description of the quality of the item being reviewed:
The function will break when the return block is fired. For example, in the above example, if the quality rating is 100, the function will return Perfect and then stop. It will not run the other tests, and won't return Excellent. Good, Fine, etc.
Inputs and Functions
You can click the gear icon to add inputs to your functions. 
You can then treat that input as a local variable in your function.
In this example, the function change font size takes a number as an input and sets the text on a Screen to this font size. The number can be fed in as the number selected on a Slider, or the user can click a Reset Button to set the font size back to 18.
