![]() Scriptable Objects can be used in many ways. Also, it promotes modularity in the code, avoiding dependencies and global managers (singletons), which allows code reusability in other projects. This is called "Referencing" the data.Įxample of a simple easy way to configure movement directions for different unit classes in my board game. The SO is a tool that Unity provides as a data container to reduce the memory usage with unnecessary information. With ScriptableObjects, to pre-inject data all you need to do is drag and drop your data. This is a far cry from code-only DI frameworks with complicated configuration code that requires advanced IDE support before it becomes excessively messy to navigate through. That means your classes can be saved, with pre-injected data, as a file in your project. ScriptableObjects are Unity Objects that can be serialized as a file. This is especially important to us since games often have very complex, asynchronous state, so we should make debugging as painless as possible. Unity was actually built with visual DI built-in from the ground up and we can build a simple, effective DI “framework” using nothing but Unity-provided objects. ![]() Using dependency injection allows us to have a buffer layer in-between that injects the required wheels for us. You do not want to waste your time in this self-made hell. / The parameter that will be sent to the OnEnter handler. / that will be send to the next state's OnEnter handler. Now what if there’s a need to use BlueWheels instead of RedWheels? Changing the wheels can be quite a debugging nightmare. Extensions /// A lightweight state machine that support either update or coroutine pattern for states update. Simple example would be a Car class, which has a reference to the RedWheels class. This goes hand-in-hand with the “Composition over Inheritance” principle, so classes are loosely coupled with each other. It is basically where the parent classes passes everything the child classes needs to instantiate itself. Awesome Unity: Dependency Injection through ScriptableObjects Introduction Dependency Injectionĭependency Injection(DI), also known as Inversion of Control, is something most people have heard of.
