How to Start Making Games in Unity: Complete Beginner Guide 2025

Ever dreamed of building your own Mario Kart or cozy farming sim? You’re in the right place. Unity makes that dream way less scary than it sounds. Spoiler alert: I built my first rolling-ball game in 47 minutes while eating cold pizza. If I can do it, so can you.

So here’s what we’ll cover today:

Get Unity running without the tech headaches
Click around the interface without getting lost
Write one tiny script that actually moves stuff
Build a mini-game you can send to your mom
Avoid the mistakes that make beginners quit

Ready? Let’s make something cool.

Wait, Why Unity? (The Honest Version)

Look, I know GameMaker and Godot exist. Here’s why I still tell my friends to start with Unity:

It works everywhere. One click and your game runs on phones, Switch, even the weird browser your uncle still uses.

The Asset Store is like free DLC. Need a dragon? 3 bucks. Need realistic grass? Someone already made it. I once bought a pack of 500 sound effects for less than a coffee.

YouTube loves Unity. Type “Unity how to” and you get 4.2 million videos. Stuck at 2 AM? Someone’s got your back.

C# won’t bite. It’s like English with curly braces. My 12-year-old cousin picked it up in a weekend.

Getting Unity on Your Machine (Mac or PC)

Here’s the thing about installation guides they’re usually boring. Let’s fix that.

Step 1: Grab Unity Hub

Think of Unity Hub as your game dev Netflix. It keeps track of all your Unity versions and projects in one place. Download it from unity.com. Takes like 5 minutes on decent wifi.

Step 2: Pick Your Unity Flavor

When Unity Hub asks which version, here’s what matters:

Latest LTS = stable like grandma’s cookie recipe
Beta versions = cool but might explode
Android/iOS modules = only if you want mobile games

Pro tip: Start with just PC/Mac. You can add mobile stuff later when your game doesn’t look like abstract art.

Step 3: Create Your First Project

Hit “New Project” and you’ll see templates. Here’s the cheat sheet:

3D = most tutorials use this
2D = perfect for platformers or pixel art
URP = fancy graphics that might melt old laptops

I always pick 3D. You can make 2D games in 3D projects anyway. Mind blown, right?

The Unity Interface Isn’t Scary (Promise)

First time opening Unity feels like walking into NASA mission control. Let’s break it down into bite-sized pieces.

Scene View: Your Digital Playground

This is where you build stuff. Drag a cube here, add a light there. It’s like LEGO but the blocks don’t hurt when you step on them.

Quick trick: Right-click + WASD to fly around. Feels like a drone simulator.

Game View: See What Players See

Hit the play button and boom you’re inside your game. This view shows exactly what players will experience. No surprises at launch.

Hierarchy: Your Object List

Everything in your game lives here. Player? Check. Enemy? Check. That random floating cube you forgot about? Also check. It’s basically a fancy grocery list.

Inspector: The Control Panel

Click any object and this panel shows all its settings. Want your cube red? Change the color here. Need your player to jump higher? Adjust the jump force. It’s like the settings menu but for every single thing.

Project Window: Your Toy Box

All your art, sounds, scripts live here. Organize it like you organize your actual desktop (which means… maybe organize it better than your actual desktop).

Your First Script: Make Stuff Move

Time for the fun part. We’re writing 12 lines of code that make a ball roll around. Copy-paste friendly:

using UnityEngine;
 
public class PlayerMove : MonoBehaviour
{
    public float speed = 5f;
    
    void Update()
    {
        float sideways = Input.GetAxis("Horizontal") * speed * Time.deltaTime;
        float forward = Input.GetAxis("Vertical") * speed * Time.deltaTime;
        
        transform.Translate(sideways, 0, forward);
    }
}

What this does in plain English:

W and S = forward and back
A and D = left and right
Speed = 5 (change this number to go faster or slower)

Attaching Your Script (The Easy Way)

Make a sphere (GameObject → 3D Object → Sphere)
Drag your script from Project window onto the sphere in Hierarchy
Hit Play and use WASD to roll around
Giggle like a 5-year-old because you just made something move with code

Build a Rolling Ball Game in 10 Minutes

Let’s make something you can actually share. This mini-game has:

A player ball you control
Ground to roll on
Collectible coins
A score that works

Step 1: The World

Add a plane for ground (GameObject → 3D Object → Plane)
Make it big scale it to 5, 1, 5
Add some color so it’s not boring gray

Step 2: Your Hero

Create a sphere and place it above the ground
Add a Rigidbody component (Component → Physics → Rigidbody)
This gives your ball physics so it falls and rolls

Step 3: Movement Magic

Use that PlayerMove script from earlier
Attach it to your sphere
Test with WASD

Step 4: Collectibles

Make small cubes as coins
Create a new script called “CoinCollector”
When the ball touches a coin, destroy the coin and add 1 to score

using UnityEngine;
 
public class CoinCollector : MonoBehaviour
{
    public int score = 0;
    
    void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.CompareTag("Coin"))
        {
            score++;
            Destroy(other.gameObject);
            Debug.Log("Score: " + score);
        }
    }
}

Don’t forget to tag your coins as “Coin” in the Inspector!

Debugging Without Losing Your Mind

Bugs happen. Here’s how to squash them fast:

The Console is your best friend. Window → General → Console. Red text = problems, yellow text = warnings.

Debug.Log is printf for games. Add Debug.Log("I got here!"); in your code to see if it’s actually running.

Play mode changes don’t save. Purple text in Hierarchy means you’re in play mode. Stop before making changes you want to keep.

Made something cool? Let’s get it to your friends:

File → Build Settings
Pick PC, Mac & Linux Standalone
Click Build
Choose a folder (I use Desktop for quick tests)
Zip the folder and send it

Mobile tip: Building for phones needs extra setup. Start with PC/Mac first, tackle mobile later when you’re hooked.

Common Beginner Mistakes (And How to Dodge Them)

Mistake #1: Making everything perfect before testing Fix: Hit play every 5 minutes. Test small pieces often.

Mistake #2: Following 47 tutorials at once Fix: Finish one tutorial completely before starting another. Your brain will thank you.

Mistake #3: Naming files “test1”, “test2”, “final”, “finalfinal” Fix: Use real names like “PlayerController” and “EnemyAI”. Future-you will be less confused.

Mistake #4: Giving up when code doesn’t work Fix: Unity’s error messages usually tell you the exact line. Read them they’re helpful, not scary.

Your Next Steps

You’ve got Unity running and a ball that rolls. What now?

Week 1: Make 3 tiny games. Pong, endless runner, simple shooter. Don’t aim for art, aim for finished.

Week 2: Pick a tutorial series and follow it completely. Brackeys on YouTube is gold.

Week 3: Join a game jam. Ludum Dare or itch.io week-long jams are perfect for beginners.

Resources that won’t waste your time:

Brackeys YouTube (RIP, but videos still rock)
Unity Learn (official, free, actually good)
r/Unity3D subreddit (helpful community)
Unity documentation (Ctrl+T in any script opens it)

“The best time to start making games was 10 years ago. The second best time is right after you finish reading this guide. Your future players are waiting.”
