Editor Properties: (see get_editor_property/set_editor_property)

  • allow_tick_before_begin_play (bool): [Read-Write] 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 for network (overrides bOnlyRelevantToOwner).
  • author (str): [Read-Write] The author is the group or person responsible for the test. Generally you should use a group name like ‘Editor Team’ or ‘Rendering Team’. When a test fails it may not be obvious who should investigate so this provides a associate responsible groups with tests.
  • auto_destroy_when_finished (bool): [Read-Write] 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] Automatically registers this actor to receive input from a player.
  • block_input (bool): [Read-Write] If true, all input on the stack below this actor will not be considered
  • can_be_damaged (bool): [Read-Write] Whether this actor can take damage. Must be true for damage events (e.g. ReceiveDamage()) to be called. https://www.unrealengine.com/blog/damage-in-ue4: TakeDamage(), ReceiveDamage():
  • can_be_in_cluster (bool): [Read-Write] If true, this actor can be put inside of a GC Cluster to improve Garbage Collection performance
  • custom_time_dilation (float): [Read-Write] 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.
  • description (str): [Read-Write] A description of the test, like what is this test trying to determine.
  • enable_auto_lod_generation (bool): [Read-Write] If true, and if World setting has bEnableHierarchicalLOD equal to true, then it will generate LODActor from groups of clustered Actor
  • find_camera_component_when_view_target (bool): [Read-Write] If true, this actor should search for an owned camera component to view through when used as a view target.
  • generate_overlap_events_during_level_streaming (bool): [Read-Write] If true, this actor will generate overlap events when spawned as part of level streaming. You might enable this is in the case where a streaming level loads around an actor and you want overlaps to trigger.
  • hidden (bool): [Read-Write] Allows us to only see this Actor in the Editor, and not in the actual game. SetActorHiddenInGame():
  • ignores_origin_shifting (bool): [Read-Write] Whether this actor should not be affected by world origin shifting.

  • instigator (Pawn): [Read-Write] Pawn responsible for damage and other gameplay events caused by this actor.
  • is_editor_only_actor (bool): [Read-Write] Whether this actor is editor-only. Use with care, as if this actor is referenced by anything else that reference will be NULL in cooked builds
  • is_enabled_value (bool): [Read-Write] Allows a test to be disabled. If a test is disabled, it will not appear in the set of runnable tests (after saving the map).
  • min_net_update_frequency (float): [Read-Write] Used to determine what rate to throttle down to when replicated properties are changing infrequently
  • net_cull_distance_squared (float): [Read-Write] Square of the max distance from the client’s viewpoint that this actor is relevant and will be replicated.
  • net_dormancy (NetDormancy): [Read-Write] Dormancy setting for actor to take itself off of the replication list without being destroyed on clients.

  • net_use_owner_relevancy (bool): [Read-Write] If actor has valid Owner, call Owner’s IsNetRelevantFor and GetNetPriority
  • observation_point (Actor): [Read-Write] Allows you to specify another actor to view the test from. Usually this is a camera you place in the map to observe the test.

  • on_actor_begin_overlap (ActorBeginOverlapSignature): [Read-Write] Called when another actor begins to overlap this actor, for example a player walking into a trigger. For events when objects have a blocking collision, for example a player hitting a wall, see ‘Hit’ events. Components on both this and the other Actor must have bGenerateOverlapEvents set to true to generate overlap events.:
  • on_actor_end_overlap (ActorEndOverlapSignature): [Read-Write] Called when another actor stops overlapping this actor. Components on both this and the other Actor must have bGenerateOverlapEvents set to true to generate overlap events.:
  • on_actor_hit (ActorHitSignature): [Read-Write] 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 collisions during physics simulation to generate hit events, ‘Simulation Generates Hit Events’ must be enabled.:

Returns:
Return type:bool
log_message(message) → None

Log Message

Parameters:message (str) –
observation_point

(Actor) – [Read-Write] Allows you to specify another actor to view the test from. Usually this is a camera you place in the map to observe the test. Not useful when running on a build farm, but provides a handy way to observe the test from a different location than you place the functional test actor.

on_additional_test_finished_message_request(test_result) → str

On Additional Test Finished Message Request

Parameters:test_result (FunctionalTestResult) –

Return type:str
on_test_finished

Returns:
Return type:bool

receive_prepare_test() → None

Prepare Test is fired once the test starts up, before the test IsReady() and thus before Start Test is called. So if there’s some initial conditions or setup that you might need for your IsReady() check, you might want to do that here.

receive_start_test() → None

Called once the IsReady() check for the test returns true. After that happens the test has Officially started, and it will begin receiving Ticks in the blueprint.
