Introduction to Game Development

3. Basics of Game Design

Embarking on your game design journey is like setting off on a grand adventure; you have a destination in mind, but the path you take and the discoveries you make along the way are what truly define your experience. Let’s navigate the terrain of game design together, ensuring you have all the tools and maps you need to create something extraordinary.

Principles of Game Design

Game design is an art form that combines creativity, strategy, and technology. At its heart are a few core principles that can help guide you in creating engaging and enjoyable games:

  • Fun Factor: Above all, games should be fun to play. This can come from challenging puzzles, exciting stories, strategic depth, or the simple joy of exploration.
  • Clear Objectives: Players need to know what they’re supposed to do. Whether it’s rescuing a princess, solving a mystery, or building a city, having a clear goal keeps players engaged.
  • Balanced Challenges: Games should be challenging enough to be interesting but not so hard that they’re frustrating. Finding this balance is key to keeping players coming back.
  • Feedback and Rewards: Players should receive immediate feedback for their actions, along with rewards for their achievements. This could be in the form of points, new levels, character upgrades, or simply progress in the story.
  • Accessibility: Your game should be accessible to its intended audience, both in terms of gameplay difficulty and understanding how to play.

Planning Your First Game Project

Now that you’re familiar with the principles of game design, it’s time to start planning your own game. Here’s a simple roadmap to guide your creative process:

  1. Choose Your Game’s Core Idea: Think about what kind of game you’d love to play. It could be based on your favorite hobby, book, movie, or a completely original concept.

  2. Sketch It Out: Grab a piece of paper and sketch out your game’s world, characters, and key elements. Don’t worry about your artistic skills; these sketches are just for you to visualize your ideas.

  3. Decide on the Game Mechanics: Determine how players will interact with your game. Will they solve puzzles, navigate mazes, compete against others, or embark on quests? These mechanics are the building blocks of your game’s gameplay.

  4. Outline the Game’s Structure: Consider how your game will be organized. Will it have levels? How will the story unfold? What challenges will players face, and how will they progress?

  5. Think About the End Game: Decide how your game will end. Will there be a final boss battle, a puzzle to solve, or a certain score to achieve? Knowing where your game is headed can help shape its development.

Understanding Game Genres

Games can be categorized into different genres, each with its own set of conventions and expectations. Here’s a quick overview of some popular genres:

  • Platformers: These games involve jumping between platforms or over obstacles. They can be simple or complex, with enemies, puzzles, and varied environments.
  • Puzzle Games: These games challenge the player’s problem-solving skills, including logic, pattern recognition, and strategy.
  • Role-Playing Games (RPGs): RPGs involve storytelling, character development, and strategic combat. Players often embark on epic quests in these immersive worlds.
  • Simulation Games: These games simulate real-world activities, from running a farm or city to flying an airplane or managing a football team.
  • Adventure Games: Focused on story and exploration, adventure games often involve solving puzzles to progress through a narrative.

Choosing the right genre for your game idea is crucial. It helps set expectations for your players and provides a framework for your game design. If you’re passionate about a particular genre, start there. Your enthusiasm will shine through in your work.


The basics of game design are the foundation upon which all great games are built. By understanding the core principles, planning your game carefully, and choosing the right genre, you’re well on your way to creating something truly special. Remember, the journey of game design is a process of exploration and creativity. Don’t be afraid to experiment, learn from your mistakes, and most importantly, have fun!

Starting Your First Project

Imagine stepping into your workshop, where all the tools and materials you need to create your first game with Game Maker Studio are laid out before you. This is where your ideas will take shape, transforming into a game you can share with the world. Let’s walk through the steps to get your first project off the ground, making sure you understand each part of the process. It’s like building your first model airplane or crafting your first piece of art; it’s about following the steps while infusing your creation with your unique flair.

1. New Project: Laying the Foundation

Just as every building starts with a foundation, so too does your game need a base to build upon:

  • Open Game Maker Studio and look for the option to create a new project. You might see choices like “New Project from Template” or “Start from Scratch.” If you’re feeling adventurous, templates can give you a head start, but starting from scratch is a fantastic way to learn.

  • Choose Your Project Type: You’ll be presented with two pathways: Drag and Drop (DnD) or Game Maker Language (GML). Think of DnD as using pre-made building blocks to construct your game, while GML is like mixing your own concrete. If you’re new to game development, DnD is a friendly starting point, offering a visual way to understand game mechanics without diving into code immediately.

2. Naming and Saving Your Project: Giving It Identity

Every creation needs a name, a label that captures its essence:

  • Pick a Name: Give your project a name that reflects your game’s theme or the adventure players will embark on. It doesn’t have to be perfect; you can always change it later. But a good name can inspire you as you develop your game.

  • Save Your Project: Choose a location on your computer that’s easy to access. Like a craftsman organizing their workshop, keeping your game project in a designated spot ensures you can quickly find and work on it anytime.

3. Explore and Experiment: Getting to Know Your Tools

With your project created and saved, it’s time to familiarize yourself with the workspace and tools at your disposal:

  • Take a Tour: Spend some time clicking through the different areas of Game Maker Studio. Open the Asset Browser, click on the Workspace Area, and explore the Toolbar. Each click reveals new features and possibilities.

  • Create a Simple Asset: Try adding a new sprite or creating a basic object. This initial step of bringing something into your game world is thrilling and serves as a practical way to learn how different parts of the game come together.

  • Play Around with Drag and Drop: If you chose the DnD pathway, drag a few actions into an object and see what happens. It’s like playing with LEGOs; you’re seeing how different pieces fit together to create something new.

4. Setting Goals: What Do You Want to Build?

Before you dive too deep into development, take a moment to think about what you want to achieve with your first project:

  • Sketch Your Ideas: Whether it’s a simple maze game, a platformer with a quirky character, or a puzzle that challenges the mind, jot down your initial ideas. Sketching isn’t just about drawing; it’s about mapping out your vision.

  • Set Small, Achievable Goals: Your first game doesn’t have to be a masterpiece. Aim for something doable that will teach you the ropes of game development. Completing a small project is incredibly satisfying and sets the stage for more complex creations in the future.

5. Save and Test Often: Building Iteratively

As you start adding more to your game, it’s important to save your work regularly and test what you’ve built:

  • Save Your Work: Just like saving a document in school, regularly saving your game project prevents loss of progress and protects your hard work.

  • Test Early and Often: Running your game lets you see how your ideas play out in real-time. It’s like testing a recipe by tasting it; you’ll know what needs tweaking or if you’re on the right track.


Starting your first project in Game Maker Studio is an adventure filled with learning and creativity. By following these steps, you’re not just beginning a new project; you’re taking the first steps on a journey that will teach you about game development and about yourself as a creator. Remember, the goal isn’t just to finish a game; it’s to grow, experiment, and enjoy the process. Welcome to the world of game making!

The Main Areas of Game Maker Studio

Embarking on your game development journey with Game Maker Studio, think of your workspace as a craftsman’s shop, filled with various stations and tools designed to bring your vision to life. Among these, a critical yet often understated tool is the Inspector Panel. Let’s integrate this into our exploration of Game Maker Studio’s main areas:

  1. Workspace Area:

    • Your workbench, where the bulk of your game’s assembly takes place. This tabbed area is where you can open different files and editors, like the Room Editor for designing levels or the Code Editor for scripting your game’s mechanics.
  2. Asset Browser:

    • The parts organizer, which houses all the components of your game, categorized for easy access. Here, you’ll find Sprites (visual assets), Sounds (audio assets), Objects (interactive elements combining sprites with code), and Rooms (the environments or levels of your game), among others. This organizer keeps your game components tidy and within reach.
  3. Properties Panel:

    • The instruction manual for your assets, detailing the settings and options for whatever asset you’ve selected in the Asset Browser. Whether adjusting the appearance of a Sprite or setting the properties of an Object, this panel is essential for customizing the behavior and appearance of your game elements.
  4. Toolbar:

    • The tool rack, providing quick access to frequently used tools and functions such as creating a new project, saving your work, or running your game to test it. Located at the top of the interface, it’s the go-to spot for common tasks.
  5. The Room Editor:

    • Your blueprint table, where you lay out the designs for your game’s levels. It’s here that you arrange objects, design level layouts, set backgrounds, and orchestrate how everything comes together to create engaging gameplay environments.
  6. The Code Editor:

    • The schematics drawer, where the detailed programming that powers your game’s mechanics is written. For those times when you need to go beyond the visual programming offered by Drag and Drop, the Code Editor allows for precise control over your game’s behavior through GML (Game Maker Language).
  7. Inspector Panel:

    • The magnifying glass, which offers a closer look at the details of the currently selected asset or project element. When you select an object in the Room Editor or a piece of code in the Code Editor, the Inspector Panel displays relevant properties, variables, and other context-specific information. This panel is invaluable for fine-tuning details, optimizing performance, and debugging, acting as a dynamic reference guide that adjusts to your current focus in the project.

The integration of the Inspector Panel into the main areas of Game Maker Studio highlights its role as a crucial tool in the game development toolkit. By offering detailed insights into the properties and settings of your game’s assets and elements, the Inspector Panel ensures that you have all the information you need at your fingertips, enabling you to make precise adjustments and informed decisions as you bring your game to life.

4. Introduction to Game Maker Language (GML)

Delving into Game Maker Language (GML) is like unlocking a new level of wizardry in your game development journey. It allows you to control the magic of your game world with precision and creativity. Fear not, young wizard, for GML is a friendly companion on your quest. Let’s take a closer look at this powerful language and how you can start using it to bring your game ideas to life.

Drag and Drop vs. Game Maker Language

Game Maker Studio offers two paths for creating your games: the Drag and Drop (DnD) system and the Game Maker Language (GML). Both paths lead to the same destination, but they offer different journeys.

  • Drag and Drop: Imagine assembling your game with magical building blocks. Each block represents a different action or event in your game. This visual approach is great for beginners, as it helps you understand game logic without writing any code.
  • Game Maker Language (GML): This is the written spellbook of your game. By learning GML, you gain the ability to script complex behaviors, fine-tune game mechanics, and unlock a whole new world of possibilities. Think of it as moving from simple magic tricks to mastering deep arcane knowledge.

Basics of Programming in GML

Programming might seem daunting at first, but GML is designed to be accessible. It uses English-like syntax, which makes it easier to learn. Here are some fundamental concepts to get you started:

  • Variables: Variables are like labeled jars where you can store numbers, text, or other data. For example, you might have a variable named score to keep track of the player’s points.
score = 0; // This sets the score to 0
  • Conditional Statements: These are the “if-then” decisions in your game. If a certain condition is true, then an action happens. They help control the flow of the game based on players’ actions or game events.
if (score >= 100) {
show_message("You win!");
  • Loops: Loops repeat an action multiple times. They’re useful for tasks that need to happen over and over, like moving a character across the screen or checking for collisions.
for (var i = 0; i < 10; i++) {

Understanding Variables, Loops, and Conditional Statements

These three elements are the bread and butter of programming in GML. Let’s explore how they work together with a simple example:

Imagine you’re creating a game where a character collects stars. Each star increases the player’s score, and when the score reaches a certain number, the player wins.

  • Variables: You’ll need a variable to keep track of the score.
score = 0;
  • Conditional Statements: To check if the player has won, you’ll use a conditional statement.
if (score == 10) {
show_message("Congratulations, you've collected all the stars!");
  • Loops: If you want to create ten stars randomly placed in the room, you could use a loop.
for (var i = 0; i < 10; i++) {
instance_create_layer(random(room_width), random(room_height), "Instances", obj_star);

Tips for Learning GML

  • Start Small: Begin with simple scripts to get a feel for how GML works. Try changing the color of an object or making an object move with keyboard controls.
  • Use the Documentation: Game Maker Studio comes with extensive documentation and a helpful community. Whenever you’re stuck or curious about how to do something, these resources are invaluable.
  • Practice, Practice, Practice: Like any language, the best way to learn GML is by using it. Set yourself small challenges or mini-projects to apply what you’ve learned.


Embarking on the journey to learn Game Maker Language is an exciting step in your game development adventure. GML unlocks a world of possibilities, allowing you to bring more complex and refined ideas to life in your games. Remember, the path of learning is filled with trials and triumphs. Be patient with yourself, and enjoy the process of discovery and creation. With each line of code, you’re not just building games; you’re crafting worlds.
