GeNa gives you the flexibility to go fully procedural or fully manual or somewhere in between and cuts days and weeks out of level generation. Let’s run the program, input a number into the right window, and see what number is printed.GeNa is the swiss army knife of spawning systems, enabling the rapid creation of gorgeous looking environments. import random dice_input = input() dice_roll = random.randint(1, dice_input) print(dice_roll)

Now we have quick little dice roller! But what if we are in a Dungeons & Dragons game and need dice with more, or less, than 6 sides? If we add back in the input() function we learned about earlier and replace our 6 argument with the new input value, we can quickly roll any sided dice without needing to adjust the code itself. Last, we print the contents of dice_roll: import random dice_roll = random.randint(1,6) print(dice_roll) randint() will return a number that will be assigned to the variable dice_roll. To randomly get a number from 1 to 6, we state in randint() that the minimum number is 1, and the maximum number is 6. randint() import random dice_roll = random.randint(1,6) There are more aspects of functions to cover but I will talk more about them in another article. Notice how the function has two arguments and calling the function has two numbers? The function always specifies how many arguments are required for it to run. The function takes in arguments, executes some logic, and can be called/executed endlessly in another part of the code. The arguments are always variables, so no putting integers or objects in the parentheses. In Python, a function always starts with “def” followed by the name of the function, and an open/close parentheses for containing the arguments. Notice how a = a * 2 and return a + b are indented? That indicates they exist within the function while the other code does not. For quick reference, this is what an example function looks like: def my_function(a, b): a = a * 2 return a + b print(my_function(1, 2)) print(my_function(15, 1))
The functions then output to variables, as we will see shortly. Functions can take in inputs, called arguments, into themselves to process. In this lesson, we will be working with variables and functions. Variables store information, functions process information via variables and execute logic, conditions determine whether to execute certain logic, and loops iterate the same logic a certain number of times. FunctionsĪll basic programming can be summed up by 4 components: variables, functions, conditions, and loops. Randint(), which stands for “random integer”, takes two arguments: the min and max integers. As you gain more experience, you’ll become aware of the many built-in packages as well as the third-party packages you can import, saving you time. By importing it, we can use one of its functions, randint(), so we don’t have to write it ourselves. We are going to import a package, or a bunch of code someone else has already written for us, called random. It’s not that interesting if you know what you’re printing out, so let’s add some randomness to the scenario. That window on the left is where you type in your code, and when you click “run” the output of your program will appear on the right. But first, we need a place to run our code! I’ll cover creating a Python environment on your own computer in a later article but for now, head on over to Programmiz. Today, we are going to create a simple dice roller using 4 lines of code. Python, like most languages, is case-sensitive, so if you have any issues, just make sure no variables got accidently capitalized! Last, Python uses indentation, or 4 spaces, to determine what code is in a function or a condition but we will talk more about that in the next section. Due to how it’s built, there’s no extra steps between writing the code and running the code. Python is a high-level language that has become more popular recently due to its ease of use and applications in data science and machine learning. Let’s get started! Today’s Topic: Dice rollerĪ quick note about Python itself. Luckily, there are easier ways for newcomers to learn code that doesn’t involve a “trial by fire.” In each part of this series, I will introduce several concepts related to coding, note some best practices, and together we will create a fun project that you can keep and extend on your own. While my teacher showed us stack implementations and encapsulation, I was trying to figure out why my compiler was rejecting 3 lines of code. As a fellow gamer, this was great! The only problem was, the programming language taught was C++. So he set forth to teach us all about programming while putting it into video game terms. In my very first Intro to Programming course in college, I had a teacher who aspired to become a video game programmer.
