Metal Gear Solid 3: Snake Eater had a creative feature that few expected when it was released on the PlayStation 2 back in 2004. It had a boss fight where, if you closed the game and didn't play it for two weeks, the boss would die of old age, and you'd proceed to the next level. Incidentally, if you...

Inventory items. Weapons carried. Checkpoints. These are all groups of related items in a game you should store together, and lists and arrays are the perfect data structures for that. Lists and arrays in C# are examples of collections that store items. They save you the trouble of manually creating...

Methods, sometimes called functions, perform actions in a game. If you want the player to run, jump, attack, heal, reload, or perform any other action, you'll most likely use one. Methods are named using verbs - words that represent actions. Examples include "Run", "Jump", "Attack", or "Reload". You ...

Fields and properties tell you more about a class. They're technically variables, so they're like mini-storage locations for any information related to the class. Since classes are declared using nouns, think of fields and properties as the adjectives. For example, if the game you're making in the Uni...

Access modifiers restrict or authorize access to certain parts of the game you're building in the Unity Game Engine. Controlling access is important because, as you add more gameplay mechanics, user interface (UI) behavior, and assets, the code becomes more complex, and the risk of introducing bugs in...

Classes are the building blocks of any game you'll make in the Unity Game Engine. They interact with each other to create amazing gameplay mechanics. Each class in your game should handle one thing. For example, code related to the main character, such as movement, attacking, and remaining health...

Loops are one of the fundamental tools you'll use when making a game in the Unity Game Engine. You can use them to execute code multiple times without repeating it or to search a collection of items for one that meets a specific criterion. When something happens in a loop, it progresses until the end...

Conditional statements control the execution of your Unity game's code, a programming concept known as control flow. One of the simplest use cases for conditional statements is moving the character in a game you're building in the Unity Game Engine. If the player presses the W key, the character shoul...

Enums in C# store related constants. If the game you're building in the Unity Game Engine has seasons or the days of the week, you can store them in an enum. Despite storing related constants, enums aren't the same as other types in C# used to store many values, such as lists or arrays. The difference...

Booleans in C# are like on/off switches. They're often used with conditional statements to control the flow of your code's execution. Booleans can only be one of two values: true or false. These values have the same meaning in programming as they do in English, and they play a part in how booleans are...

Whether you're working with non-playable character (NPC) names or text in your game's user interface (UI), you'll most likely run into strings in C#. Strings store and manipulate text. They're the foundation of the majority of text-related code you'll write for your game made in the Unity Game Engine...

If the player in your game picks up some ammo, you'll need to update the ammo count to reflect this increase. It's also common to reduce the player's health whenever they take damage. These are operations that will require operators. Operators can be used to do mathematical operations such as addition...

From the remaining lives a player has to the health potions in their inventory, every video game deals with numbers at some point or another, so knowing how to work with them in C# is crucial to making a successful game in the Unity Game Engine. Numbers in C# can be generally categorized into two type...

A constant in C#, the half-brother to a variable, is like a mini-storage location to store temporary data you'll reuse when building a video game in the Unity Game Engine. As the name suggests, a constant is a value that stays the same after it is created. It can only be updated in one place: where yo...

A variable in C# can be thought of as a mini-storage location to store temporary data you plan on reusing while building a video game in the Unity Game Engine. Variables are fundamental to any video game and make up a large percentage of the code you'll write, whether by hand or using visual scripting...
