EDrawType Source code

The DrawType enumneration sets how the actor displays. Some of these options work with another property to set what is displayed.

DT_None

The actor isn't displayed at all. bHidden instead in most cases because it will allow the actor to still show up in UnrealEd.

DT_Sprite

Display a sprite with the material set in the Texture property.

DT_Mesh

Display the mesh set in the Mesh property.

DT_Brush

Only for Brush classes.

DT_RopeSprite

DT_VerticalSprite

ELightType Source code

EMusicTransition Source code

ENetRole Source code

Net variables.

ROLE_None

This means that none of the actor's attributes will not be replicated at all. Examples for this kind of actors are the GameInfo, Mutators and GameRules as well as some explosion effects and decals in UT. Note that Actor's with this role can still be instantiated on network game clients if spawned from the right function. For example if an Actor with ROLE_None is instantiated from a simulated event PostBeginPlay() function it will be created on both the server and the client as this function is invoked on both. However the server-side Actor and the client-side Actor are two completely independant entities. This means that destroying the actor on the server will not destroy the actor on the client (and vice-versa).

ROLE_DumbProxy

The actor is replicated, but can't execute any functions on the remote side. It will update when variables are replicated to it but will not attempt to interpolate.

ROLE_SimulatedProxy

The actor is replicated and may execute simulated functions and simulated state code on the remote side. Often this kind of actor simulates its behavior based on initially replicated properties without (much) further "help" from the server.

ROLE_AutonomousProxy

Autonomous proxies come with some more magic built-in. They are basically simulated proxies, but may execute simulated and non-simulated functions on the client owning/controlling this actor (only on that client!). In UT only PlayerPawns are autonomous proxies, in UT2003 only PlayerControllers are. Every other client sees them as a regular simulated proxy. Player-controlled actors, such as the guided redeemer missile (GuidedWarshell in UT or RedeemerWarhead in UT2003) are autonomous proxies on the controlling player's client, too.

ROLE_Authority

All functions can be executed. This role is only allowed on the machine the actor was spawned on. All actors on the server or in standalone games have Role== ROLE_Authority. Never manually set the RemoteRole on the authorative version of an actor or the Role on a replicated version of the actor to this value.

EPhysics Source code

Actor's PhysicsType is set in the Physics property. Use the SetPhysics() method to change.

PHYS_CinMotion

(new in UT2003)

PHYS_Falling

Automatically applies the gravity of the current zone. Pawn-set acceleration in the Z direction is ignored.

PHYS_Flying

The Pawn or Actor can move independantly from gravity. Velocity on the Z axis is ignored.

PHYS_Hovering

This is is a fun Physics type. When you an actors physics to PHYS_Hovering, it, er, hovers a few UU off the ground. If you do this to an xPawn, for example, it will act kind of like a hovercraft. Friction is reduced (so you slide around, and slide down ramps), and if you go at speed up an incline you can do some massive jumps.

PHYS_Interpolating

Used in conjunction with bInterpolating in Actor. Seems to also use the PhysRate and PhysAlpha parameters. Seems to be a leftover from the pre-Matinee days.

PHYS_Karma

Signals an Actor is to be effected by the Karma engine.

PHYS_KarmaRagDoll

This is used for dead pawns.

PHYS_Ladder

Applies to an Actor when they are climbing a ladder.

PHYS_MovingBrush

Used for Movers

PHYS_None

No native physics code is applied.

PHYS_Projectile

Uses velocities on all 3 axes but DOES NOT use the current Zone's ZoneGravity and ZoneFluidFriction members to adjust velocity. This means that actors with a velocity are not affected by gravity or friction. Actors with this physics setting do not have any freedom of movement.

PHYS_Rolling

(removed in UT2003)

PHYS_RootMotion

(new in UT2003)

PHYS_Rotating

Only rotation changes. Location doesn't change. If bRotateToDesired is false, then the Actor rotates according to RotationRate. If bRotateToDesired is true, then the Actor rotates to the rotation specified by DesiredRotation at the speed specified by RotationRate.

PHYS_Spider

Similar to PHYS_Walking except it applies to an Actor against any surface, not just a "ground" surface. An Actor in PHYS_Spider will move against a horizontal or vertical surface just like in PHYS_Walking. When the end of the surface is reached the Pawn will be set to PHYS_Falling. PHYS_Spider only works on one plane, it will not allow a Pawn to move across perpendicular walls.

PHYS_Swimming

Similar to PHYS_Flying, but also take the zone's FluidFriction into account.

PHYS_Trailer

Used to set an Actor to follow its Owner. An Actor set this way has no physics of its own, (*including collision) and simply follow their Owner around. NOTE: There are two settings in the Actor class which can specify the actions of a PHYS_Trailer. First is bTrailerPrePivot, which, when set to True, causes the Actor in PHYS_Trailer to be positioned away from its Owner by the vector value set in PrePivot. If not set or left at 0, the Actor in PHYS_Trailer will have the same location as its Owner. Secondly, there is bTrailerSameRotation, which causes the Actor in PHYS_Trailer to have the same Rotation as its Owner no matter where it is.

PHYS_Walking

Native physics code for Pawn class only. Applies all the things that make a pawn move around on the ground. Must have a Base set, without a Base to walk on, this turns to PHYS_Falling.
