C# is one of the best programming languages for beginners who want to enter game development. It is widely used with Unity and gives developers a strong combination of readable syntax, powerful programming features, and practical game-development tools.

Unlike lower-level languages such as C++, C# handles many complex memory tasks automatically. Therefore, beginners can focus more on learning programming, gameplay systems, and game engines.

At the same time, C# is not limited to simple projects. Developers use it to build 2D games, 3D games, mobile games, PC games, VR experiences, AR applications, and multiplayer systems.

This complete beginner’s guide explains how C# works in game development, what skills you should learn first, how Unity uses C#, and how you can progress from basic coding to complete game projects.

What Is C#?

C# is a modern, general-purpose programming language.

It supports important programming concepts such as:

Object-Oriented Programming
Strong typing
Automatic memory management
Generics
Events
Interfaces
Asynchronous programming

C# is used in several areas of software development. However, in the gaming world, it is strongly associated with Unity.

Because Unity supports C# scripting, developers can use C# to control gameplay, characters, enemies, UI, animation, audio, and many other systems.

Why Is C# Popular for Game Development?

There are several reasons why C# is popular among Game Developers.

First, its syntax is easier to understand than many low-level languages.

Second, it works very well with Unity.

In addition, C# includes many features that help developers organize large projects.

For example, you can use:

Classes
Interfaces
Events
Lists
Dictionaries
Properties
Generics

These features make it easier to create clean and reusable game systems.

Moreover, C# uses automatic memory management. As a result, beginners do not need to manually manage memory in the same way as C++ developers.

Is C# Good for Beginners?

Yes. C# is a strong beginner-friendly language.

It teaches important programming concepts without being overly complicated.

For example, you can learn:

Variables
Conditions
Loops
Functions
Classes
Objects
Collections
Events

Once you understand these concepts, you can apply them directly inside Unity.

Therefore, C# is a practical choice if your goal is to learn programming and game development together.

What Games Can You Build With C#?

C# can be used to create many types of games.

For example:

2D platformers
Puzzle games
Endless runners
Racing games
Top-down shooters
3D adventure games
Simulation games
Mobile games
VR games
AR applications

In addition, you can use C# for both small indie projects and larger commercial games.

C# and Unity

Unity is one of the most popular game engines used with C#.

Inside Unity, developers create C# scripts and attach them to GameObjects.

These scripts can control:

Player movement
Enemy AI
Health systems
Weapons
Cameras
UI
Animation
Sound
Game states
Saving

Because of this direct integration, learning C# and Unity together is a very common beginner path.

A simple roadmap is:

C# Basics → Unity Basics → 2D Games → 3D Games → Advanced Systems

C# vs C++ for Game Development

C# and C++ are both important game-development languages. However, they are commonly used for different goals.

Feature	C#	C++
Learning Difficulty	Easier	Harder
Popular Engine	Unity	Unreal Engine
Memory Management	Automatic	More manual
Beginner Friendly	High	Medium
Indie Development	Excellent	Excellent
Mobile Development	Excellent	Good
AAA Development	Moderate	Very High
Engine Programming	Limited	Excellent

If your goal is Unity, C# is usually the better choice.

On the other hand, C++ is more suitable for Unreal Engine, graphics programming, engine development, and many AAA roles.

Now, let us go through each step in detail.

1. Install the Required Tools

Before learning game development, install the tools you need.

For C# development, popular code editors include:

Visual Studio
Visual Studio Code
JetBrains Rider

For Unity development, install:

Unity Hub
Unity Editor

After that, connect your code editor with Unity.

This setup allows you to write scripts and test them directly inside the engine.

2. Write Your First C# Program

A simple C# program looks like this:

using System;

class Program
{
    static void Main()
    {
        Console.WriteLine("Hello, Game Development!");
    }
}

This program introduces several basic concepts:

using
Classes
Methods
Output
Program structure

At the beginning, focus on understanding the structure rather than memorizing every detail.

3. Learn Variables

Variables store information.

For example:

int health = 100;
float speed = 5.5f;
bool isAlive = true;
string playerName = "Alex";

In games, variables can store:

Health
Coins
Score
Ammo
Speed
Damage
Player name

Therefore, variables are one of the first concepts you should understand.

4. Learn Data Types

C# has several useful data types.

Common examples include:

int
float
double
bool
string
char

For example:

int score = 500;
float jumpForce = 7.5f;
bool gameOver = false;
string levelName = "Forest";

Choosing the right data type keeps your code clear.

5. Learn Operators

Operators allow you to perform calculations and comparisons.

Arithmetic operators include:

+
-
*
/
%

Comparison operators include:

==
!=
>
<
>=
<=

Logical operators include:

&&
||
!

For example:

if (health <= 0)
{
    gameOver = true;
}

Operators are used constantly in gameplay code.

6. Learn Conditions

Conditions allow your program to make decisions.

For example:

if (score >= 100)
{
    Console.WriteLine("Level Complete");
}

You should learn:

if
else
else if
switch

In games, conditions may check whether:

The player is alive
A level is complete
An enemy can attack
A door can open

7. Learn Loops

Loops repeat code.

Common loop types include:

for
while
do while
foreach

Example:

for (int i = 0; i < 5; i++)
{
    Console.WriteLine(i);
}

Loops are useful when working with:

Enemies
Items
Projectiles
Scores
Inventory objects

8. Learn Functions

Functions organize reusable code.

For example:

void TakeDamage(int damage)
{
    health -= damage;
}

Instead of repeating the same logic, you can call the function whenever needed.

Game-related functions may include:

MovePlayer()
Jump()
Attack()
TakeDamage()
SaveGame()

Therefore, functions make your code easier to maintain.

9. Learn Parameters

Parameters allow you to send values into functions.

Example:

void Heal(int amount)
{
    health += amount;
}

Now you can call:

Heal(20);

or:

Heal(50);

As a result, one function can support different values.

10. Learn Return Values

Functions can also return data.

Example:

int GetHealth()
{
    return health;
}

Return values allow one system to request information from another.

11. Learn Arrays

Arrays store multiple values.

Example:

int[] scores = {100, 200, 300};

Arrays may store:

Scores
Level data
Enemy health
Item values

However, arrays have a fixed size.

For more flexibility, you will often use Lists.

12. Learn Lists

Lists can grow and shrink.

Example:

using System.Collections.Generic;

List<string> inventory = new List<string>();

inventory.Add("Sword");
inventory.Add("Potion");

Lists are extremely useful in game development.

You can use them for:

Enemies
Inventory
Quests
Players
Items

13. Learn Dictionaries

Dictionaries store key-value pairs.

Example:

Dictionary<string, int> inventory =
    new Dictionary<string, int>();

inventory["Potion"] = 5;
inventory["Sword"] = 1;

Dictionaries are useful for:

Item databases
Player stats
Configuration
Inventory quantities

14. Learn Object-Oriented Programming

Object-Oriented Programming is one of the most important parts of C#.

The main concepts include:

Classes
Objects
Inheritance
Encapsulation
Polymorphism
Interfaces

You will use these concepts frequently in Unity projects.

15. Learn Classes

A class defines a type of object.

Example:

class Player
{
    public int health = 100;

    public void TakeDamage(int damage)
    {
        health -= damage;
    }
}

Then you can create a Player object.

Player player = new Player();
player.TakeDamage(20);

Classes help organize your game systems.

16. Learn Constructors

Constructors initialize objects.

Example:

class Player
{
    public int health;

    public Player()
    {
        health = 100;
    }
}

Whenever a Player is created, health starts at 100.

17. Learn Encapsulation

Encapsulation protects internal data.

For example:

class Player
{
    private int health = 100;

    public int GetHealth()
    {
        return health;
    }
}

This prevents other systems from changing health directly.

As a result, your code becomes safer.

18. Learn Properties

Properties provide controlled access to fields.

Example:

public int Health { get; private set; } = 100;

Properties are cleaner than writing separate getter and setter methods in many situations.

19. Learn Inheritance

Inheritance lets classes reuse common behavior.

Example:

class Character
{
    public int health;
}

class Player : Character
{
}

Later, you could create:

Player
Enemy
NPC

from the same Character base class.

20. Learn Interfaces

Interfaces define common behavior.

Example:

public interface IDamageable
{
    void TakeDamage(int damage);
}

Now multiple objects can implement this behavior.

For example:

Player
Enemy
Breakable object

This creates flexible game systems.

21. Learn Enums

Enums are useful for fixed states.

Example:

enum EnemyState
{
    Idle,
    Patrol,
    Chase,
    Attack
}

Enums are useful for:

Enemy states
Weapon types
Item categories
Game states

22. Learn Events

Events are very important for building clean game architecture.

Imagine this sequence:

Player Takes Damage

↓

Health Changes

↓

UI Updates

↓

Sound Plays

Instead of connecting every system directly, events can notify other systems.

As a result, your code becomes less tightly coupled.

23. Learn Delegates

Delegates allow methods to be stored and passed around.

They are commonly used with events.

You do not need to master delegates immediately. However, understanding them will help you use event-driven programming more effectively.

24. Learn Generics

Generics allow reusable type-safe code.

For example:

List<int> scores = new List<int>();
List<string> names = new List<string>();

Here, List<T> is a generic type.

Generics are especially useful when building reusable systems.

25. Learn Null Handling

A reference can sometimes be null.

Example:

Player target = null;

Trying to access a null object may cause an error.

Therefore, always check whether an object exists before using it.

Null reference errors are common among beginners.

26. Learn Exception Handling

C# supports exceptions.

Example:

try
{
    // Code
}
catch (Exception ex)
{
    Console.WriteLine(ex.Message);
}

However, normal gameplay logic should not depend heavily on exceptions.

Use conditions for expected situations.

Start Learning Unity

Once you understand basic C#, start learning Unity.

You do not need to master the entire language first.

A better approach is:

Learn C# Basics → Start Unity → Continue Learning C# While Building Games

27. Understand the Unity Editor

Important Unity windows include:

Scene View
Game View
Hierarchy
Inspector
Project Window
Console

Learn how to move objects, create scenes, attach scripts, and test your game.

28. Learn GameObjects

GameObjects are the basic objects inside Unity scenes.

Examples include:

Player
Enemy
Camera
Coin
Weapon

However, a GameObject alone does not do much.

It becomes useful when Components are added.

29. Learn Components

Components provide functionality.

Examples include:

Transform
Rigidbody
Collider
AudioSource
Camera

Your own C# scripts also become Components when attached to GameObjects.

This is a major part of Unity’s design.

30. Learn MonoBehaviour

Many Unity scripts inherit from MonoBehaviour.

Example:

using UnityEngine;

public class Player : MonoBehaviour
{
}

This allows your script to use Unity lifecycle methods.

31. Understand Start()

Start() is commonly used for initialization.

Example:

void Start()
{
    Debug.Log("Game Started");
}

It usually runs before the first frame update.

32. Understand Update()

Update() runs every rendered frame while the script is active.

Example:

void Update()
{
    Debug.Log("Running");
}

It can be used for:

Input
Timers
Frame-based logic

However, avoid doing heavy unnecessary work inside every Update() call.

33. Understand FixedUpdate()

FixedUpdate() runs using Unity’s fixed physics timestep.

It is commonly used when working with Rigidbody-based physics.

Understanding the difference between Update() and FixedUpdate() is important.

34. Learn Transform

Every GameObject has a Transform.

Transform controls:

Position
Rotation
Scale

Example:

transform.position += Vector3.forward;

You will use Transform constantly.

35. Learn Vector2 and Vector3

Vectors are fundamental in games.

Vector2 is commonly used in 2D.

Vector3 is commonly used in 3D.

Example:

Vector3 position = new Vector3(0, 1, 0);

Learn concepts such as:

Direction
Distance
Magnitude
Normalization

36. Learn Delta Time

Games run at different frame rates.

Therefore, movement should not depend directly on FPS.

Example:

transform.position +=
    Vector3.forward * speed * Time.deltaTime;

Using delta time helps movement stay consistent across devices.

37. Learn Player Input

Players interact with games through:

Keyboard
Mouse
Controller
Touchscreen

You can use input to control:

Movement
Jumping
Attacking
Interacting
Menus

Responsive input is essential for good gameplay.

38. Build Player Movement

Player movement is a great beginner project.

Start with:

Walking
Running
Jumping

Later add:

Dash
Crouch
Climbing

A typical flow is:

Input → Direction → Movement → Animation

39. Learn Rigidbody

Rigidbody allows objects to interact with physics.

It is useful for:

Gravity
Velocity
Forces
Physical movement

For 2D games, Unity provides Rigidbody2D.

40. Learn Colliders

Colliders define physical boundaries.

Examples include:

Box Collider
Sphere Collider
Capsule Collider

For 2D games, Unity provides 2D collider versions.

41. Learn Collision Detection

Collision detection tells the game when objects touch.

Examples include:

Player hits wall
Bullet hits enemy
Car hits obstacle

Unity provides collision callbacks that your C# code can use.

42. Learn Triggers

Triggers detect overlap without acting like solid objects.

They are useful for:

Coins
Checkpoints
Doors
Enemy detection areas

This makes triggers useful for many gameplay interactions.

43. Learn Layers

Layers help control which objects can interact.

For example:

Bullets hit enemies
Players ignore friendly objects
Enemies ignore each other

Correct layer setup can simplify collision and raycasting logic.

44. Learn Raycasting

Raycasting checks what exists along a line.

It is useful for:

Shooting
Ground detection
Interaction
Enemy vision

Raycasting is one of the most useful gameplay tools in Unity.

45. Learn Cameras

Games need a camera system.

Common camera types include:

First-person
Third-person
Top-down
Follow camera

You may also add:

Camera shake
Smooth movement
Zoom

Good camera behavior improves game feel.

Building Game UI With C#

46. Learn Unity UI

Most games need interfaces.

You should learn how to create:

Main menu
Health bar
Score
Pause menu
Inventory
Settings

C# can update the UI based on gameplay data.

47. Learn Canvas

Unity UI commonly lives inside a Canvas.

Important concepts include:

RectTransform
Anchors
Layout
Scaling

Responsive UI is especially important for mobile games.

48. Connect UI to Gameplay

Suppose the player loses health.

The sequence might be:

Player Takes Damage → Health Value Changes → Health Bar Updates

This is where events and clean architecture become very useful.

Animation With C#

49. Learn the Animator

Unity’s Animator controls character animation.

You can create states such as:

Idle
Walk
Run
Jump
Attack

Then C# can control transitions between these states.

50. Learn Animation Parameters

Common Animator parameter types include:

Bool
Float
Int
Trigger

Example:

animator.SetBool("isRunning", true);

Your gameplay code can change these values when player behavior changes.

51. Learn Animation State Machines

A simple state flow might be:

Idle → Walk → Run → Jump

State machines help animation stay organized.

They are also useful for enemy AI and player states.

Enemy AI With C#

52. Start With Simple AI

Do not begin with complex AI.

Start with an enemy that can:

Patrol
Detect player
Chase
Attack

This teaches many important gameplay concepts.

53. Learn Finite State Machines

A basic enemy state system may look like:

Idle → Patrol → Chase → Attack

Each state has different behavior.

Finite State Machines are simple, practical, and widely used.

54. Learn Pathfinding

Enemies often need to move around obstacles.

Learn basic concepts such as:

Waypoints
Navigation
A* pathfinding

Unity provides navigation tools that can handle much of this for you.

Important Gameplay Systems

55. Build a Health System

Example:

public int health = 100;

public void TakeDamage(int damage)
{
    health -= damage;

    if (health <= 0)
    {
        Die();
    }
}

This teaches:

Variables
Functions
Conditions
Events
UI updates

56. Build a Combat System

A combat system may include:

Attacks
Damage
Cooldowns
Weapons
Enemy health

A common flow is:

Input → Animation → Hit Detection → Damage → Effects

57. Build an Inventory System

Inventory systems are excellent intermediate projects.

You may store:

Item ID
Name
Quantity
Type
Icon

Then add:

Add item
Remove item
Equip item
Save item

This project teaches collections and clean architecture.

58. Learn ScriptableObjects

ScriptableObjects can store reusable game data.

They are useful for:

Weapons
Items
Enemies
Character stats

For example, a weapon asset may contain:

Damage
Fire rate
Range
Price

This makes game balancing easier.

59. Learn Data-Driven Design

Avoid hard-coding every value into scripts.

Instead, separate:

Game Logic

from:

Game Data

This allows designers and developers to change values without rewriting core systems.

60. Build Save and Load Systems

Games often need to save:

Player progress
Inventory
Settings
Score
Unlocked levels

Start with local save files.

Later, explore cloud saves and backend systems.

61. Learn Serialization

Serialization converts game data into a format that can be stored.

It is useful for:

Save files
Settings
Data transfer

Understanding serialization is important for persistent game data.

Audio and Effects

62. Learn Audio

Unity supports:

Music
Sound effects
Voice
Ambient audio

Learn components such as:

AudioSource
AudioClip

Then control:

Volume
Looping
Playback

63. Learn Particle Systems

Particle systems create effects such as:

Fire
Smoke
Sparks
Explosions
Magic

C# scripts can trigger these effects during gameplay.

2D Game Development With C#

C# and Unity work very well for 2D games.

Learn:

Sprites
Tilemaps
Rigidbody2D
Collider2D
2D animation

Good beginner projects include:

Pong
Snake
Platformer
Top-down shooter

Build a 2D Platformer

A platformer is one of the best beginner projects.

It can include:

Movement
Jumping
Coins
Enemies
Health
Score
UI
Animation

By building one complete platformer, you can practice many C# concepts together.

3D Game Development With C#

Once you understand 2D fundamentals, move into 3D.

Learn:

3D movement
Models
Materials
Lighting
Cameras
Physics
Animation

Start small.

For example, create one room, one player, and a few enemies.

Learn Materials

Materials control how 3D objects appear.

They may include:

Color
Texture
Surface properties

Understanding materials is useful even if you are not a Game Artist.

Learn Lighting

Common lights include:

Directional lights
Point lights
Spotlights

Later, learn the difference between:

Baked lighting
Real-time lighting

Lighting affects both visuals and performance.

Learn Shader Basics

Shaders control how graphics are rendered.

As a beginner, you can start with:

Materials
Shader Graph
Simple visual effects

Advanced shader programming can come later.

Game Architecture With C#

As your game grows, code structure becomes more important.

Good architecture makes your project easier to:

Maintain
Debug
Extend
Test

64. Use Smaller Components

Avoid putting everything inside one massive script.

For example, instead of one Player script, separate:

PlayerMovement
PlayerHealth
PlayerCombat
PlayerInventory

This approach keeps responsibilities clear.

65. Prefer Composition Where Appropriate

Composition builds complex objects from smaller components.

For example:

Player

can contain:

Health component
Movement component
Combat component
Inventory component

This is often more flexible than deep inheritance.

66. Learn Design Patterns

Useful patterns include:

State
Observer
Factory
Command
Object Pool

However, do not use patterns only because they sound professional.

Use them when they solve a real problem.

67. Learn Event-Driven Programming

Events help different systems communicate.

Example:

Enemy Dies

↓

Score Increases

↓

UI Updates

↓

Sound Plays

This reduces direct dependencies between scripts.

Debugging C# Games

68. Learn Debug.Log

Unity provides simple logging.

Example:

Debug.Log("Player moved");

You can also use:

Debug.LogWarning
Debug.LogError

Logs help track what your game is doing.

69. Read the Unity Console

The Console displays:

Errors
Warnings
Logs

Always read the complete error message.

In many cases, the Console shows:

File name
Line number
Error type

This can save a lot of debugging time.

70. Use Breakpoints

A debugger lets you pause code and inspect values.

Use breakpoints to check:

Variables
Conditions
Call flow

Breakpoints are often better than adding many temporary logs.

Performance Optimization

71. Learn Profiling

Unity provides profiling tools.

You can measure:

CPU usage
Memory
Rendering
Physics

Profiling helps you find the real performance problem.

Therefore, avoid guessing.

72. Avoid Expensive Update Logic

Code inside Update() may run dozens of times every second.

Avoid repeating expensive work unnecessarily.

Instead, use:

Events
Cached references
Timers
State changes

when appropriate.

73. Learn Object Pooling

Creating and destroying many objects can create extra allocations.

Object pooling reuses existing objects.

It is useful for:

Bullets
Enemies
Effects

Use it when your game actually needs it.

74. Understand Garbage Collection

C# automatically manages memory.

However, frequent temporary allocations can still create performance problems.

Therefore, learn:

Object lifetime
Allocations
Garbage collection

This becomes more important as your projects grow.

75. Optimize Assets

Large assets can increase:

Memory usage
Loading times
Build size

Optimize:

Textures
Models
Audio
Animations

This is especially important for mobile games.

C# for Mobile Game Development

Unity and C# are widely used for Android and iOS games.

Important topics include:

Touch controls
Responsive UI
Screen sizes
Device performance
Battery usage
Mobile builds

Always test your game on real devices.

Android Development

When building for Android, learn:

Build settings
Permissions
App signing
Device testing

Different phones may have very different performance levels.

iOS Development

For iOS, you may also need:

Xcode
Apple signing
Provisioning
Device testing

Unity handles much of the game code, while platform tools handle the final build process.

Multiplayer Game Development With C#

Multiplayer is more advanced than single-player development.

Therefore, learn the basics first.

Then study:

Client-server architecture
Latency
Synchronization
Authority
Matchmaking

Understand Client-Server Architecture

A simple multiplayer structure is:

Player → Server ← Player

The server may control important data such as:

Health
Score
Match state

Server authority helps reduce cheating and inconsistencies.

Learn Backend Basics

Online games may require backend services for:

Authentication
Profiles
Leaderboards
Cloud saves
Match history

Basic knowledge of APIs and databases can be useful.

Async Programming in C#

C# includes modern asynchronous features.

Learn:

async
await
Task

These are useful for:

Network requests
File operations
Backend calls

However, Unity also uses its own frame-based systems.

Therefore, learn where async code is appropriate.

Coroutines in Unity

Coroutines are useful for time-based sequences.

Example:

IEnumerator WaitAndAttack()
{
    yield return new WaitForSeconds(1f);
    Attack();
}

They can be used for:

Delays
Timed actions
Simple sequences

Coroutines vs async/await

These tools solve different problems.

Coroutines are closely connected to Unity’s frame loop.

Meanwhile, async/await belongs to standard C# asynchronous programming.

Understanding both gives you more flexibility.

Testing Your Game

Do not wait until the end of development to test.

Test systems such as:

Movement
Combat
Inventory
AI
UI
Saving

Frequent testing makes bugs easier to find.

Learn Unit Testing

Some game logic can be tested without running the entire game.

For example:

Damage calculations
Inventory rules
Score calculations

Automated tests become more valuable in larger projects.

Clean C# Code

Readable code is easier to maintain.

Use:

Clear names
Small functions
Separate responsibilities
Reusable components

For example, prefer:

TakeDamage()

instead of:

DoThing()

Clear naming makes your code easier to understand later.

AI

However, avoid starting with a huge open-world project.

A small 3D game will teach you much faster.

C# for Indie Game Development

C# is a strong language for solo and indie developers.

It offers a good balance between:

Development speed
Readability
Performance
Maintainability

Therefore, small teams can build complete games without dealing with excessive low-level complexity.

C# for VR and AR

Unity and C# can also be used for:

VR games
AR applications
Training simulations
Interactive experiences

This makes C# useful beyond traditional PC and mobile games.

Is C# Hard to Learn?

C# is easier than C++ for many beginners.

However, it still requires consistent practice.

You may initially struggle with:

Classes
References
Events
Architecture

That is normal.

The best way to improve is to write code and build real features.

Should You Learn C# Before Unity?

Learn the basics first.

At minimum, understand:

Variables
Conditions
Loops
Functions
Classes
Lists

After that, start Unity.

Do not wait until you have mastered the entire language.

Is Unity Required for C# Game Development?

No.

You can learn C# through:

Console applications
Desktop projects
Coding exercises

However, if your goal is game development, Unity provides a direct way to turn your code into interactive games.

Is C# Better Than Python for Games?

It depends on your goal.

Python is excellent for:

Learning programming
Prototypes
Automation

C# is generally more practical for:

Unity games
Mobile games
2D games
3D games

Therefore, C# is often the better choice for Unity-focused Game Developers.

Is C# Better Than C++?

Neither language is universally better.

C# is easier to learn and works very well with Unity.

Meanwhile, C++ provides more low-level control and is more common in Unreal Engine and AAA engine programming.

Choose based on your target career.

Is C# Used for AAA Games?

Yes, C# is used in some commercial games and Unity projects.

However, C++ is still more common in many large AAA engines.

If your main goal is AAA Unreal development, C++ may be more relevant.

Do Game Developers Still Use C#?

Yes.

C# remains highly useful for:

Unity
Mobile games
Indie games
VR
AR
Interactive applications

It is also useful outside game development, which makes it a flexible language to learn.

What Should Be in a C# Game Developer Portfolio?

A good beginner portfolio should include several projects.

For example:

2D Platformer

Show:

Movement
Collision
Animation
Enemy AI

Top-Down Shooter

Show:

Weapons
Enemies
Object pooling
UI

Small 3D Game

Show:

3D movement
Camera
Physics
Lighting
AI

For each project, clearly explain what you personally built.
