Even though they have a set of rules, developers will usually do a little rule-bending in order to better adapt the pattern to their specific problem. In the literature of software, we will find a great number of design patterns. Then I’ll move on to explain how MVC fits on top of it, and use a little mock project as an example. I’ll start by explaining a bit of Unity’s base architecture, the Entity-Component pattern. In my seven years of development, having wrestled with my fair share of game dev spaghetti, I’ve been achieving great code structure and development speed using this design pattern. In this tutorial, I’ll relate my experience with the popular Unity game development platform and the Model-View-Controller (MVC) pattern for game development. One must carefully consider the strong and weak points of each pattern, and find the best fit for the challenge at hand. Since problems don’t come in one flavor, there isn’t a silver bullet design pattern. Less time is spent planning the methodology of development. These rules, when followed by everyone, allow legacy code to be better maintained and navigated, and new code to be added more swiftly. They help one or more programmers separate core pieces of a large project and organize them in a standardized way, eliminating confusion when some unfamiliar part of the codebase is encountered. This is why software design patterns exist they impose simple rules to dictate the overall structure of a software project. Companies you’ve worked for can’t just look up your contact information and ask you every time they want to fix or improve the codebase (and you don’t want them to either). Code must be maintained and may last for a long time. Soon, it is easy to see that in large or small teams, one cannot recklessly do as one pleases. The bigger the project, the bigger the spaghetti. Each new challenge drives home an important lesson: From there, bigger and bigger assignments are bound to follow. I those cases, you can show an apologising message to the user and reload the initialization scene so that you reboot (bootstrap) the whole application without actually exiting it.First-time programmers usually start learning the trade with the classic Hello World program. Equally important is the explicit system initialization order you can set, building the dependency graph.Īnother extra benefit will be present if you add a system to detect unhandled exceptions. This will help you creating, configuring and maintaining global objects: advertisement managers, audio system, debug options, etc. Have a single-entry point in your game for initializing and keeping global objects. A DI system is a critical need for a great architecture. Your code will be cleaner and your developers happier. It is possible to write one in less than 100 lines of code as reference, you may have a look at the same DI script I used when developing Diamond Dash in Unity.ĭI allows you to write less code and less code means less chances of things going the wrong way. You will learn a lot through it and will be prepared to deal with possible DI issues in the future. However, I encourage you to write your own DI class if you have the time. You may use famous DI frameworks such as Zenject and StrangeIoC. They should focus just on their small, well-defined tasks as an extension of the single responsibility principle. Your classes are not responsible for getting the references they need, do not force them to. The path to a better Unity Architecture – Summary
