What is a mod

When talking about modding, people often mix up three very different things: playing, installing mods, and creating them yourself. Setting them apart right away helps you know exactly what to expect here.

Playing

Playing is enjoying the game as designed by the studio. You experience the story and play within the limits built by the developers. That is where all of us start, naturally.

Installing a mod

Installing a mod is enjoying someone else's creation. You download a file, drop it into your game directory, and discover something new: an extra vehicle, a trainer menu, or overhauled visuals. You change your game as an end user. In Lab 0, we use a diagnostic script to check that the setup works.

Creating a mod

Creating a mod is being the author of the change. You are the one imagining a new behavior, writing the code to bring it to life, compiling it, and watching it run in game.

Why this distinction matters

People often say "I mod my game" to describe all three. Installing mods is a great way to have fun and see what is possible. But building your own mod teaches you so much more: you discover the real rules of the game engine and how to run your logic in harmony with it.

Practically speaking, it also keeps you from debugging the wrong thing: when something breaks, you will immediately know whether the issue comes from your game folder, an external mod, or your own code.

Where we go next

In this course, we follow a natural path: play the game, test your setup with a simple tool, and then start building your own creations step by step. The next lesson touches on what drives us to take that step: why create mods in the first place.
