public abstract class LifecycleAttributeBase : RequiredMemberAttribute
Remarks
This is the abstract base class for all lifecycle callback attributes. Do not inherit from this class directly; use the specific lifecycle attributes instead:
- OnAssemblyLoadedAttribute / OnAssemblyUnloadingAttribute - Per-assembly loading lifecycle.
- OnCodeLoadedAttribute / OnCodeUnloadingAttribute - Code loading lifecycle.
- OnCodeInitializingAttribute / OnCodeDeinitializingAttribute - Object serialization lifecycle.
Lifecycle Timing:
Code reload order (Editor only):
- OnCodeDeinitializingAttribute - Objects serialized.
- OnCodeUnloadingAttribute - Code about to unload.
- OnAssemblyUnloadingAttribute - Each assembly about to unload, in reverse dependency order.
- (Code unloads and reloads)
- OnAssemblyLoadedAttribute - Each assembly loaded, in dependency order.
- OnCodeLoadedAttribute - Code loaded.
- OnCodeInitializingAttribute - Objects deserialized.
Initial code load (Editor and Player):
- OnAssemblyLoadedAttribute - Each assembly loaded, in dependency order.
- OnCodeLoadedAttribute - Code loaded.
- OnCodeInitializingAttribute - Called before initial scene loads.
Shutdown (Editor and Player):
- OnCodeUnloadingAttribute - Code about to unload.
- OnAssemblyUnloadingAttribute - Each assembly about to unload, in reverse dependency order.
