*Five principles of Object-Oriented Design: SRP – Single Responsibility Principle OCP – Open/Closed Principle LSP – Liskov Substitution Principle ISP – Interface Segregation Principle DIP – Dependency Inversion Principle. Difficulties in applying SOLID principles in Unityĭue to its architecture, Unity makes it difficult to apply SOLID principles*. So if you want to avoid it, you need to write a native plugin that will handle the field in the right way. A typical solution is to use an additional InputField that is built into the keyboard. When you select such a field, you lose “focus” and you cannot change the cursor position, for instance, because the system keyboard has appeared. Unity does not properly support InputField objects by default. Let’s take a look at the example of building a mob app (e.g. In a situation when let’s say, you want to do a good job with InputField, you still have to write your own plugin that will handle it well. design patterns) and interest in available plugins, unless you want to waste your time breaking open doors. Often newbies take shortcuts using primitive solutions such as operating mainly on static classes, abusing singletons or storing logic in one file consisting of thousands of lines of code, trying to justify such behavior by “done is better than perfect” principle.Ĭreating effective architecture and advanced functionalities in Unity, similar to UI creation, requires learning certain conventions (e.g. The Unity environment itself does not encourage or help programmers apply good programming practices. Without programming experience, you easily end up with chaotic architecture or no clear thought-through application structure. When working with Unity, achieving clean architecture and code might be a challenge. Challenges in achieving clean code and architecture using Unity For more complex tasks a custom approach is usually required, such as creating UI on your own or using external solutions for that. All in all, it is a gaming engine and is therefore not universal. The UI tool in Unity is flexible but not suitable for every project. Xcode for IOS), but we believe it will evolve over time and switch to something like HTML/CSS. You won’t find any structured UI in this engine like in others (e.g. However, for more comprehensive and scalable solutions, it will require a lot of work since UI tools in Unity are not so developed, standardized and automated. When creating UI for the needs of the majority of games, you most probably won’t encounter any troubles. Overall working on UI in Unity is easy but only to a certain extent. One of such pitfalls lies behind creating a user interface (UI). Common pitfalls in Unity Building UI with UnityĮven though the engine is generally very friendly for beginners, there are many bad programming practices that an inexperienced developer can easily step into. The application development process in Unity can be compared to an avalanche: the more experience the programmer has, the more this application grows and gains quality. This factor in combination with the lack of programming experience leads to a high number of poor applications and games created on Unity engine.įor this reason, Unity is often referred to as an “easy to learn, hard to master” platform. More often it’s a result of the very low entry threshold for creating applications on Unity. In our opinion, it doesn’t have to be the fault of the engine itself. Although there are many sceptics who also question the quality of games on Unity engine. Indeed, this engine was created mainly for game development. Many developers don’t consider Unity to be an ideal engine for creating mobile applications, in particular – utility applications. Is Unity engine really that bad as people are saying? Only when a company exceeds this amount it is required to switch to the paid version of the tool. The wide pool of possibilities that this engine provides opened the way to new professions such as technical artists, gameplay programmers, UI programmers, and network engineers.īusiness-wise, Unity is a good free option for small and medium-sized companies whose gross annual income is not higher than USD 100,000. There are also lots of guidelines for new users, which make Unity a good starting point for beginners, learners and amateur game developers. It provides a set of tools (assets, plugins, libraries), the majority of which can be found on GitHub, Bitbucket, the Unity Asset Store and other similar platforms.Ī large community around Unity with its rich knowledge base allows finding ready solutions for common errors in no time. Unity is a popular development platform that can be used for free (with some exceptions).
