Tutorial 4: Basic Functions in GDScript

GDScript with Basic Functions

Declaring a function in GDScript is not difficult; just like what is shown in the image above. You can declare a function with func someFunctionName(some_variable): , but I prefer declaring it with specific types in order to reduce bugs and errors, especially when the program gets too large. I declare it this way func someFunctionName(some_variable: TYPE) -> TYPE: and make sure you indent the codes within the function. You can download the source code here.

This tutorial solves for the square of a base. The function is called with an input variable and returns a float type that is assigned to a variable sqr, which is then converted to 2 decimal places and into a string before printing into the Output console.

The Square of the Base

As for your practice, create a function that returns true if the input integer is an even number with the use of a modulus or remainder operator %.
