UT2003 :: Object >> ParticleEmitter (Structs)

Structs used by ParticleEmitter classes.

### Particle

Used internally to hold data of individual particles.

int BoneIndex
color Color
vector ColorMultiplier
int Flags
int HitCount
vector Location
float Mass
float MaxLifetime
vector OldLocation
vector OldMeshLocation
vector RevolutionCenter
vector RevolutionsMultiplier
vector RevolutionsPerSecond
vector Size
vector SpinsPerSecond
vector StartLocation
vector StartSize
vector StartSpin
int Subdivision
float Time
vector Velocity
vector VelocityMultiplier

### ParticleColorScale

Used by the ColorScale array.

color Color
  The color used to draw the particle. The alpha component isn't used for most drawing modes.
float RelativeTime
  A value between 0.0 and 1.0 that specifies the relative life time of the particle when this particular color should be used.

### ParticleRevolutionScale

Used by the RevolutionScale array.

vector RelativeRevolution
float RelativeTime
  A value between 0.0 and 1.0 that specifies the relative life time of the particle when this particular relovution value should be used.

### ParticleSound

range Pitch
range Probability
range Radius
sound Sound
range Volume
int Weight

### ParticleTimeScale

Used by the SizeScale array.

float RelativeSize
  A multiplier for the particle's size.
float RelativeTime
  A value between 0.0 and 1.0 that specifies the relative life time of the particle when this particular size multiplier should be used.

### ParticleVelocityScale

Used by the VelocityScale array.

float RelativeTime
  A value between 0.0 and 1.0 that specifies the relative life time of the particle when this particular velocity multiplier should be used.
vector RelativeVelocity
  A multiplier for the particle's velocity.
