RuntimeManager

Namespace: Molca
File: Packages/com.molca.core/Runtime/RuntimeManager.cs

When to use

RuntimeManager is the single bootstrap entry point for every Molca-based project. You interact with it when:

Waiting for initialization before accessing any service or subsystem (always call await RuntimeManager.WaitForInitialization() before resolving services).
Registering or resolving services through the built-in DI container (GetService<T>, RegisterService<T>).
Injecting dependencies into runtime-created objects that missed the automatic scene injection pass.
Creating factory-produced instances with constructor + field injection via CreateWithInjection<T>.

Bootstrap

After scene load, static initialization loads Molca Project Settings, instantiates the configured RuntimeManager prefab, calls DontDestroyOnLoad, then runs async InitializeAsync: GlobalSettings load, subsystem discovery, service registration, scene-wide dependency injection, then IsReady.

Using from code

await RuntimeManager.WaitForInitialization();

Service API

Prefer GetService<T>() / TryGetService<T>(). For RuntimeSubsystem types, GetSubsystem<T>() still resolves the same instance but is labeled legacy in source comments.

Method	Signature	Description
`WaitForInitialization`	`static async Awaitable WaitForInitialization()`	Blocks until `IsReady` is true
`GetService<T>`	`static T GetService<T>() where T : class`	Resolve a registered service; returns `null` if not found
`TryGetService<T>`	`static bool TryGetService<T>(out T service)`	Try-pattern resolution; returns `true` if found
`HasService<T>`	`static bool HasService<T>()`	Check if a service type is registered
`RegisterService<T>`	`static void RegisterService<T>(T instance)`	Register a singleton service instance
`BindService<TI,TImpl>`	`static void BindService<TI, TImpl>()`	Lazy singleton — created on first request
`RegisterFactory<T>`	`static void RegisterFactory<T>(Func<T> factory)`	Transient — factory called each resolution
`GetSubsystem<T>`	`static T GetSubsystem<T>() where T : RuntimeSubsystem`	Legacy; delegates to `GetService<T>`
`InjectDependencies`	`static void InjectDependencies(object target)`	Inject `[Inject]` fields/properties on any object
`InjectInto`	`static void InjectInto(MonoBehaviour target)`	Inject into a specific runtime-created MonoBehaviour
`CreateWithInjection<T>`	`static T CreateWithInjection<T>() where T : class`	Construct + inject fields/properties
`RegisterSubsystem`	`static async void RegisterSubsystem(RuntimeSubsystem s)`	Register an external subsystem after init
`DeregisterSubsystem`	`static void DeregisterSubsystem(RuntimeSubsystem s)`	Remove a previously registered subsystem
`RunCoroutine`	`static Coroutine RunCoroutine(IEnumerator e)`	Start a coroutine on the RuntimeManager instance

Troubleshooting

Services/subsystems are null in Start or Awake: call await RuntimeManager.WaitForInitialization() before resolving. [Inject] fields are null until the injection pass completes.
MolcaProjectSettings failed to load: ensure a MolcaProjectSettings asset exists under Resources/ and the RuntimeManager prefab field is assigned.
Multiple instances of subsystem type warning: only one enabled component of each RuntimeSubsystem type should exist on the prefab. Duplicates are automatically removed.
Dynamically created objects have null [Inject] fields: call RuntimeManager.InjectInto(component) after Instantiate / AddComponent — the automatic scene pass only runs once during init.
Circular dependency detected: two services depend on each other during resolution. Refactor one to use lazy resolution or event-based decoupling.

Runtime subsystem — child components on the prefab
Dependency injection — [Inject]
Molca Project Settings — configures the RuntimeManager prefab reference
EventDispatcher — dispatches TypedEvents.ApplicationInitialized after init
