Join us as we unravel the intricate tapestry of game development patterns. Let’s start by answering the question, “What is a game programming pattern?”.

What Are Game Programming Patterns

A game programming pattern constitutes a recurrently encountered resolution for a specific quandary during the process of architecting a program. 

Dissimilar to off-the-shelf functions or libraries, a pattern cannot be readily extracted and duplicated into a program. A pattern doesn't epitomize a particular snippet of code; rather, it embodies a comprehensive conceptual approach to a distinct problem, necessitating customization to align with your program's requisites.

Patterns are often misconstrued with algorithms, given that both notions expound on customary resolutions for recognized issues. However, while an algorithm embodies a meticulous sequence of actions, a pattern serves as an abstract depiction of a solution, the instantiation of which may differ across divergent programs.

To draw a parallel, an algorithm corresponds to a culinary recipe with well-defined steps, whereas a pattern resembles an engineering blueprint that delineates a solution without delineating the precise steps of execution.

Game Programming Patterns

How to create a mobile game? Every masterpiece is built upon a foundation of carefully crafted decisions. These decisions are informed by a myriad of challenges, from optimizing performance to creating captivating player experiences. This is where game development patterns step into the spotlight – tried and tested solutions that address common hurdles developers encounter during the creation of games.

Just as a skilled composer combines musical notes to create harmonious melodies, game developers weave together these patterns to craft engaging and immersive gaming experiences. From optimizing performance to enhancing maintainability, these patterns are the building blocks that empower developers to bring their creative visions to life. Here are the game development patterns we use to develop mobile games.

The Observer Pattern

The Observer pattern is a behavioral design pattern that establishes a subscription mechanism, allowing certain objects to observe and react to events occurring in other objects.

In other words, this pattern focuses on what happens after an event has occurred. Which methods should be called after defeating an enemy to update the score, display a death animation, etc.? These methods need to subscribe to the event.

This pattern is so popular that C# has implemented it for you. Unity also has its own implementation. So, your options are:

  • EventHandler
  • Action
  • UnityEvent
  • Custom implementation using delegates

Using events makes it convenient to synchronize players' actions in board game app development.

Enemy Generation Mechanisms in Gaming

In gaming scenarios where players engage adversaries, the prototype pattern emerges as a potent tool for spawning new enemies through the emulation of existing prototypes. This expedites the creation of a diverse array of enemies featuring distinct traits and behaviors, harnessing pre-established objects as blueprint models.

Swift Weapon and Item Fabrication

For games encompassing an array of weapons and items, the prototype pattern proves invaluable in swiftly generating novel instances rooted in preexisting ones. This accelerated approach streamlines the game development timeline and facilitates equilibrium.

Realm Formation Dynamics

In the realm of games housing procedurally generated worlds—think sandbox-style gameplay—the prototype pattern assumes significance by enabling the construction of varied world elements, encompassing terrains, structures, and flora, all facilitated through prototype-driven diversity.

Creation of Artefacts and Spells

Within the realm of role-playing games, the prototype pattern's utility materializes in the creation of fresh artefacts, spells, or capabilities grounded in established ones. This infusion injects diversity and distinctiveness into the fabric of game mechanics.

Object Pooling

In in-game domains where the generation and removal of objects entail resource intensiveness—imagine projectiles or explosions—the object pool pattern steps in as an efficient manager of in-memory objects, curtailing performance overhead.

Singleton Structure

In gaming contexts necessitating the singular existence of particular objects—such as resource managers or sound systems—this example of a game programming pattern ensures the sole instantiation of an object within the system.

Service Location Strategy

Amidst expansive games replete with an array of services and resources—ranging from databases to animation systems—this game programming pattern example proffers a centralized avenue to access diverse services, streamlining dependency administration and injection intricacies.

Single Singleton Approach

Consolidate all manager classes that were previously implemented as Singletons into a singular Singleton class. When seeking access to the SaveGame object, simply call upon GameController.Instance.getSaveGameManager(). This streamlined structure centralizes managerial control, promoting efficient code organization.

Exemplars of Alternative Design Patterns:

In the realm of game development, an array of alternative design patterns offers innovative approaches to solving common challenges. These patterns often diverge from the conventional methods, offering fresh insights and techniques to enhance code structure, maintainability, and overall game performance. Exploring these alternative patterns can provide developers with a versatile toolkit to tackle diverse issues and create more robust and efficient games. Let's delve into a few of these alternative game development patterns.

  • Absence of Classes: No presence of classes whatsoever. Most Singleton instances function as assistants, and often, the manager's role can be eliminated with the auxiliary code integrating into the managed class.
  • Static Structures: Representing the Service Locator pattern, static classes serve as central repositories for obtaining services or instances.
  • Unity's Built-in Retrieval: The usage of Unity's Find() and SendMessage() functions, though notably sluggish and hence best to be avoided. If their usage is imperative, confine them to a singular occurrence, typically during the Start method, to obtain script references.
  • Reference Assignments to Pre-existing Objects: Involves linking references to pre-existing entities. This entails attaching the script-transformed singleton to public variables accessible via the Editor. The complication arises from the need to replicate this process across various locations should references change.
  • Global Event Mechanism: Essentially rooted in the Observer design pattern, this entails a singular system for events spanning across the entirety. Although a Singleton remains necessary for this overarching system, other singleton instances can be eradicated.
  • Dependence Injection: Involves infusing object references (formerly singletons) into dependent classes, typically through constructors. Dependency Injection frameworks are also available to streamline this procedure.

Conclusion

In essence, a design pattern encapsulates the recurrent solutions to specific challenges encountered during program architecture. Unlike off-the-shelf functions or libraries, a pattern is not a mere extract-and-paste solution. Instead, it embodies a holistic conceptual approach to a particular problem, necessitating customization to harmonize with the program's unique requirements.

Patterns often find themselves mistakenly conflated with algorithms, as both offer customary solutions to recognized issues. However, while an algorithm presents a step-by-step recipe, a pattern serves as an abstract blueprint, outlining a solution without detailing the exact execution sequence.

Transitioning to the realm of game development patterns, we've explored a myriad of innovative solutions. From the Observer pattern that orchestrates event-driven reactions, to the prototype pattern's prowess in spawning diverse enemies and objects, these patterns epitomize the marriage of creativity and technology. The alternatives, including Singleton structures and Dependency Injection, demonstrate the versatility of design choices in optimizing code structure and performance.
