Actor: The base class of all actors. Actor is the base class of all gameplay objects. A large number of properties, behaviors and interfaces are implemented in Actor, including:

- Display - Animation - Physics and world interaction - Making sounds - Networking properties - Actor creation and destruction - Actor iterator functions - Message broadcasting

Constants[edit]

TRACEFLAG_Bullet[edit]

Value: 1

List of extra trace flags

TRACEFLAG_PhysicsVolumes[edit]

Value: 2


TRACEFLAG_SkipMovers[edit]

Value: 4


TRACEFLAG_Blocking[edit]

Value: 8


REP_RBLOCATION_ERROR_TOLERANCE_SQ[edit]

Value: 16.0f

when bReplicateRigidBodyLocation is true, the root body of a ragdoll will be replicated but this is not entirely accurate (and isn't meant to be) as the other bodies in the ragdoll may interfere this can then result in jittering from the client constantly trying to apply the replicated value so if the client's error is less than this amount from the replicated value, it will be ignored

MINFLOORZ[edit]

Value: 0.7


ACTORMAXSTEPHEIGHT[edit]

Value: 35.0

max height floor walking actor can step up to

RBSTATE_LINVELSCALE[edit]

Value: 10.0


RBSTATE_ANGVELSCALE[edit]

Value: 1000.0


RB_None[edit]

Value: 0x00

Not set, empty

RB_NeedsUpdate[edit]

Value: 0x01

If bNewData & RB_NeedsUpdate != 0 then an update is needed

RB_Sleeping[edit]

Value: 0x02

if bNewData & RB_Sleeping != 0 then this RigidBody needs to sleep

Properties[edit]

Property group 'Advanced'[edit]

bConsiderAllStaticMeshComponentsForStreaming[edit]

Type: bool

If true, texture streaming code iterates over all StaticMeshComponents found on this actor when building texture streaming information.

bEdShouldSnap[edit]

Type: bool

Snap to grid in editor.

bHiddenEd[edit]

Type: bool

Modifiers: const

Is hidden during editing.

bHiddenEdGroup[edit]

Type: bool

Modifiers: const

Is hidden by the group brower.

bLockLocation[edit]

Type: bool

Prevent the actor from being moved in the editor.

Property group 'Attachment'[edit]

Base[edit]

Type: Actor

Modifiers: const

Actor we're standing on.

BaseBoneName[edit]

Type: name


BaseSkelComponent[edit]

Type: SkeletalMeshComponent


bHardAttach[edit]

Type: bool

Modifiers: const


bIgnoreBaseRotation[edit]

Type: bool


bShadowParented[edit]

Type: bool

If TRUE, BaseSkelComponent is used as the shadow parent for this actor.

Property group 'Collision'[edit]

bCollideComplex[edit]

Type: bool

Ignore Simple Collision on Static Meshes, and collide per Poly.

BlockRigidBody[edit]

Type: bool

Modifiers: const, transient

mirrored copy of CollisionComponent's BlockRigidBody for the Actor property window for LDs (so it's next to CollisionType) purely for editing convenience and not used at all by the physics code

bNoEncroachCheck[edit]

Type: bool

For encroachers, don't do the overlap check when they move. You will not get touch events for this actor moving, but it is much faster. This is an optimisation for large numbers of PHYS_RigidBody actors for example.

bPathColliding[edit]

Type: bool

this actor should collide (if bWorldGeometry && bBlockActors is true) during path building (ignored if bStatic is true, as actor will always collide during path building)

bPhysRigidBodyOutOfWorldCheck[edit]

Type: bool

If true, do a zero-extent trace each frame from old to new Location when in PHYS_RigidBody. If it hits the world (ie might be tunneling), call FellOutOfWorld.

CollisionComponent[edit]

Type: PrimitiveComponent


CollisionType[edit]

Type: ECollisionType

Modifiers: const, transient

enum for LDs to select collision options - sets Actor flags and that of our CollisionComponent via PostEditChange()

Default value: COLLIDE_NoCollision

Property group 'Debug'[edit]

bDebug[edit]

Type: bool


Property group 'Display'[edit]

bHidden[edit]

Type: bool

Modifiers: const

If this is True, all PrimitiveComponents of the actor are hidden. If this is false, only PrimitiveComponents with HiddenGame=True are hidden.
