ParticleFields

List of particle fields:

! Note: all fields default to 0 or "" unless otherwise indicated or inherited from special case particle types.

Spawn Related Fields

. *count (count)*

- count: specifies number of particles to spawn with point effects

. *step (step)*

- step: specifies Quake units per particle to spawn with trails

! Note: step (x) is a synomyn for count 1/(x)

. *die (die)*

- die: specifies time in seconds it takes for the particle to die. A value of 0 means that the particle will be rendered for a duration of 1 frame.

. *diesubrand (rand)*

- rand: subtracts a random value from 0 to rand from the die time on particle spawn, and causes the particle to "decay" for that amount of time

! Note: Using diesubrand with delta ramps will cause weird things to happen.

. *assoc (particleeffectname)* - particleeffectname: name of other particle effect to execute when the current particle effect is executed ! Note: Using assoc to loop back to the same particle effect is invalid.

. *emit (particleeffectname)* - particleeffectname: specifies the particle effect that the current particles should emit

. *emitinterval (time)* - time: specifies the time between the emitting of the chosen effect (a value of less than 0 means to emit the chosen effect as a trail)

. *emitintervalrand (timerand)* - timerand: adds a value between 0 and timerand to the time interval on emit

. *emitstart (time)* - time: specifies time that emitting of the chosen effect should start after particle spawn

Render Related Fields

. *type (type)* - type: specifies the type of particles to use for the effect, possible types are "normal", "beam", and "decal". ! Note: type defaults to "normal" ! Note: "decal" is currently experimental. Use at your own risk.
