UActorComponent
Choose your OS:
UActorComponent
class UActorComponent :&&&&public

ActorComponent is the base class for components that define reusable behavior that can be added to different types of Actors. ActorComponents that have a transform are known as SceneComponents and those that can be rendered are PrimitiveComponents.
Array of user data stored with the component
bAllowAnyoneToDestroyMe
Can this component be destroyed (via K2_DestroyComponent) by any parent
bAllowConcurrentTick
Can we tick this concurrently on other threads?
bAllowReregistration
bAutoActivate
Whether the component is activated at creation or must be explicitly activated.
bAutoRegister
Does this component automatically register with its owner
bCanEverAffectNavigation
Whether this component can potentially influence navigation
bEditableWhenInherited
Whether the component is currently active.
bIsEditorOnly
If true, the component will be excluded from non-editor builds
bNavigationRelevant
Cached navigation relevancy flag for collision updates
bNetAddressable
Is this component safe to ID over the network by name?
bNeverNeedsRenderUpdate
If true, this component never needs a render update.
bPhysicsStateCreated
If the physics state is currently created for this component
bRegistered
Indicates if this ActorComponent is currently registered with a scene.
bRenderStateCreated
If the render state is currently created for this component
bReplicates
Is this component currently replicating? Should the network code consider it for replication? Owning Actor must be replicating first!

If true, we call the virtual BeginPlay

If true, we call the virtual InitializeComponent
