Unity Game Development Path
Learn C# inside Unity, one idea at a time, then build ten 3D games feature by feature. Each game runs next to your code, in the browser.

Each one is real Unity C# running in your browser. Press Play, then move a slider to change a value in the code and see what it does to the game. On a phone, use the keys on the screen.
Roll the ball into the coins with the arrow keys or WASD, and jump with Space. Push force up and the ball takes off.

float x = Input.GetAxis("Horizontal");
float z = Input.GetAxis("Vertical");
rb.AddForce(new Vector3(x, 0f, z) * force);
}
public void AddCoin()
{
coins++;
ShowScore();
}
void ShowScore()
{
scoreText.text = "Coins: " + coins;
}
}
Writing these scripts yourself is what the path teaches: free, in your browser.

Intro to Variables
Audio
A variable is a named container that stores a value you can reference later in your program.
In Python, you create one by writing the name, an equals sign, then the value you want to store.
The value can change over time. Reassigning the name simply points it to a new value.

Add to LinkedInWhy learn Unity game development on Coddy
- It starts at C#, so you never open a Unity script unsure what a class or a list is.
- You build whole games, one feature per lesson, until they can be won and lost.
- The game runs next to your code, on a computer, a Chromebook or a phone.
- The code is real Unity C#: MonoBehaviour, Rigidbody, TextMeshPro, the Input System and ScriptableObjects.
Questions about Unity game development
How do you make a game in Unity?
A Unity game is scenes of GameObjects plus C# scripts that make them behave. Start inside the engine, learning each piece of C# the first time a game needs it, then build games feature by feature, with object oriented C# before the bigger architecture. This path follows that order.
Do I need the Unity editor for this path?
No. Every lesson and every game runs in your browser, on Coddy's own engine that copies Unity's API. You need the Unity editor, free for personal use on Windows, macOS and Linux, to build and publish a game of your own.
Can I rebuild these games in Unity?
Yes. The scripts are standard Unity C#. In the editor you build the scene yourself (the objects, their colliders and the camera), add the scripts as components and press Play.
What if I already know C#?
Start at the second chapter of Unity scripting basics: the first one teaches the basics of C#. A later chapter on loops and methods will go quickly too, and you can skip the object oriented C# step.
How long does the whole path take?
About four months at an hour a day: about three months of Unity with the C# it needs, a few weeks of object oriented C#, and a few days for each extra game.
Is Coddy part of Unity?
No. Coddy is not affiliated with or endorsed by Unity Technologies. Unity is its trademark.
Do I get a certificate for the Unity Game Developer path?
Yes. Finish every step and you get one free certificate for the whole Unity Game Developer path. It lists each course you finished on the way, and links each course's own certificate, so anyone can check every skill it names. You can add it to your LinkedIn profile. It is a certificate of completion from Coddy, not an accredited qualification.
