Enumeration Type Documentation

EDynamicEmitterType

enum EDynamicEmitterType

Dynamic particle emitter types

NOTE: These are serialized out for particle replay data, so be sure to update all appropriate when changing anything here.

Enumerator
DET_Unknown
DET_Sprite
DET_Mesh
DET_Beam2
DET_Ribbon
DET_AnimTrail
DET_Custom

EParticleDetailMode

enum EParticleDetailMode : int

Detail mode for scene component rendering.

Enumerator

EParticleSignificanceLevel

enum class EParticleSignificanceLevel : uint8

strong

A level of significance for a particle system. Used by game code to enable/disable emitters progressively as they move away from the camera or are occluded/off screen.

Enumerator
Low	Low significance emitter. Culled first.
Medium	Medium significance emitter.
High	High significance emitter. Culled last.
Critical	Critical emitter. Never culled.
UMETA

EParticleStates

enum EParticleStates

Enumerator
STATE_Particle_JustSpawned	Ignore updates to the particle
STATE_Particle_Freeze	Ignore updates to the particle
STATE_Particle_IgnoreCollisions	Ignore collision updates to the particle
STATE_Particle_FreezeTranslation	Stop translations of the particle
STATE_Particle_FreezeRotation	Stop rotations of the particle
STATE_Particle_CollisionIgnoreCheck	Combination for a single check of 'ignore' flags
STATE_Particle_DelayCollisions	Delay collision updates to the particle
STATE_Particle_CollisionHasOccurred	Flag indicating the particle has had at least one collision
STATE_Mask	State mask.
STATE_CounterMask	Counter mask.

EParticleSystemInsignificanceReaction

enum class EParticleSystemInsignificanceReaction : uint8

strong

Determines what a particle system will do when all of it's emitters become insignificant.

Enumerator
Auto	Looping systems will DisableTick. Non-looping systems will Complete.
Complete	The system will be considered complete and will auto destroy if desired etc.
DisableTick	The system will simply stop ticking. Tick will be re-enabled when any emitters become significant again. This is useful for persistent fx such as environmental fx.
UMETA	As DisableTick but will also kill all particles.
