- class unreal.InternalToolFrameworkActor(outer=None, name='None')¶
AInternalToolFrameworkActor is a base class for internal Actors that the ToolsFramework may spawn (for gizmos, mesh previews, etc). These Actors may need special-case handling, for example to prevent the user from selecting and deleting them.
Editor Properties: (see get_editor_property/set_editor_property)
actor_guid(Guid): [Read-Write] Actor Guid: The GUID for this actor.
- Note: Don’t use VisibleAnywhere here to avoid getting the CPF_Edit flag and get this property reset when resetting to defaults.
See FActorDetails::AddActorCategory and EditorUtilities::CopySingleProperty for details.
allow_tick_before_begin_play(bool): [Read-Write] Allow Tick Before Begin Play: Whether we allow this Actor to tick before it receives the BeginPlay event. Normally we don’t tick actors until after BeginPlay; this setting allows this behavior to be overridden. This Actor must be able to tick for this setting to be relevant.
always_relevant(bool): [Read-Write] Always Relevant: Always relevant for network (overrides bOnlyRelevantToOwner).
auto_destroy_when_finished(bool): [Read-Write] Auto Destroy when Finished: If true then destroy self when “finished”, meaning all relevant components report that they are done and no timelines or timers are in flight.
auto_receive_input(AutoReceiveInput): [Read-Write] Auto Receive Input: Automatically registers this actor to receive input from a player.
block_input(bool): [Read-Write] Block Input: If true, all input on the stack below this actor will not be considered

call_pre_replication_for_replay(bool): [Read-Write] Call Pre Replication for Replay
can_be_damaged(bool): [Read-Write] Can be Damaged: Whether this actor can take damage. Must be true for damage events (e.g. ReceiveDamage()) to be called. see: https://www.unrealengine.com/blog/damage-in-ue4 see: TakeDamage(), ReceiveDamage()
can_be_in_cluster(bool): [Read-Write] Can be in Cluster: If true, this actor can be put inside of a GC Cluster to improve Garbage Collection performance
custom_time_dilation(float): [Read-Write] Custom Time Dilation: Allow each actor to run at a different time speed. The DeltaTime for a frame is multiplied by the global TimeDilation (in WorldSettings) and this CustomTimeDilation for this actor’s tick.

default_update_overlaps_method_during_level_streaming(ActorUpdateOverlapsMethod): [Read-Only] Default Update Overlaps Method During Level Streaming: Default value taken from config file for this class when ‘UseConfigDefault’ is chosen for ‘UpdateOverlapsMethodDuringLevelStreaming’. This allows a default to be chosen per class in the matching config. For example, for Actor it could be specified in DefaultEngine.ini as:
[/Script/Engine.Actor] DefaultUpdateOverlapsMethodDuringLevelStreaming = OnlyUpdateMovable
Another subclass could set their default to something different, such as:
[/Script/Engine.BlockingVolume] DefaultUpdateOverlapsMethodDuringLevelStreaming = NeverUpdate see: UpdateOverlapsMethodDuringLevelStreaming

generate_overlap_events_during_level_streaming(bool): [Read-Write] Generate Overlap Events During Level Streaming: If true, this actor will generate overlap Begin/End events when spawned as part of level streaming, which includes initial level load. You might enable this is in the case where a streaming level loads around an actor and you want Begin/End overlap events to trigger. see: UpdateOverlapsMethodDuringLevelStreaming
hidden(bool): [Read-Write] Hidden: Allows us to only see this Actor in the Editor, and not in the actual game. see: SetActorHiddenInGame()

is_spatially_loaded(bool): [Read-Write] Is Spatially Loaded: Determine if this actor is spatially loaded when placed in a partitioned world.
If true, this actor will be loaded when in the range of any streaming sources and if (1) in no data layers, or (2) one or more of its data layers are enabled. If false, this actor will be loaded if (1) in no data layers, or (2) one or more of its data layers are enabled.

on_actor_hit(ActorHitSignature): [Read-Write] On Actor Hit: Called when this Actor hits (or is hit by) something solid. This could happen due to things like Character movement, using Set Location with ‘sweep’ enabled, or physics simulation. For events when objects overlap (e.g. walking into a trigger) see the ‘Overlap’ event. note: For collisions during physics simulation to generate hit events, ‘Simulation Generates Hit Events’ must be enabled.

on_take_radial_damage(TakeRadialDamageSignature): [Read-Write] On Take Radial Damage: Called when the actor is damaged by radial damage.
only_relevant_to_owner(bool): [Read-Write] Only Relevant to Owner: If true, this actor is only relevant to its owner. If this flag is changed during play, all non-owner channels would need to be explicitly closed.
optimize_bp_component_data(bool): [Read-Write] Optimize BPComponent Data: Whether to cook additional data to speed up spawn events at runtime for any Blueprint classes based on this Actor. This option may slightly increase memory usage in a cooked build.
pivot_offset(Vector): [Read-Write] Pivot Offset: Local space pivot offset for the actor, only used in the editor
primary_actor_tick(ActorTickFunction): [Read-Write] Primary Actor Tick: Primary Actor tick function, which calls TickActor(). Tick functions can be configured to control whether ticking is enabled, at what time during a frame the update occurs, and to set up tick dependencies. see: https://docs.unrealengine.com/API/Runtime/Engine/Engine/FTickFunction see: AddTickPrerequisiteActor(), AddTickPrerequisiteComponent()
relevant_for_level_bounds(bool): [Read-Write] Relevant for Level Bounds: If true, this actor’s component’s bounds will be included in the level’s bounding box unless the Actor’s class has overridden IsLevelBoundsRelevant
replay_rewindable(bool): [Read-Write] Replay Rewindable: If true, this actor will only be destroyed during scrubbing if the replay is set to a time before the actor existed. Otherwise, RewindForReplay will be called if we detect the actor needs to be reset. Note, this Actor must not be destroyed by gamecode, and RollbackViaDeletion may not be used.
replicate_movement(bool): [Read-Write] Replicate Movement: If true, replicate movement/location related properties. Actor must also be set to replicate. see: SetReplicates() see: https://docs.unrealengine.com/InteractiveExperiences/Networking/Actors

runtime_grid(Name): [Read-Write] Runtime Grid: Determine in which partition grid this actor will be placed in the partition (if the world is partitioned). If None, the decision will be left to the partition.
spawn_collision_handling_method(SpawnActorCollisionHandlingMethod): [Read-Write] Spawn Collision Handling Method: Controls how to handle spawning this actor in a situation where it’s colliding with something else. “Default” means AlwaysSpawn here.
sprite_scale(float): [Read-Write] Sprite Scale: The scale to apply to any billboard components in editor builds (happens in any WITH_EDITOR build, including non-cooked games).
tags(Array(Name)): [Read-Write] Tags: Array of tags that can be used for grouping and categorizing.
update_overlaps_method_during_level_streaming(ActorUpdateOverlapsMethod): [Read-Write] Update Overlaps Method During Level Streaming: Condition for calling UpdateOverlaps() to initialize overlap state when loaded in during level streaming. If set to ‘UseConfigDefault’, the default specified in ini (displayed in ‘DefaultUpdateOverlapsMethodDuringLevelStreaming’) will be used. If overlaps are not initialized, this actor and attached components will not have an initial state of what objects are touching it, and overlap events may only come in once one of those objects update overlaps themselves (for example when moving). However if an object touching it does initialize state, both objects will know about their touching state with each other. This can be a potentially large performance savings during level loading and streaming, and is safe if the object and others initially overlapping it do not need the overlap state because they will not trigger overlap notifications.
Note that if ‘bGenerateOverlapEventsDuringLevelStreaming’ is true, overlaps are always updated in this case, but that flag determines whether the Begin/End overlap events are triggered. see: bGenerateOverlapEventsDuringLevelStreaming, DefaultUpdateOverlapsMethodDuringLevelStreaming, GetUpdateOverlapsMethodDuringLevelStreaming()
