SparkSpawnFrames

How many frames a spark system goes on throwing bursts for.

Specification
Applies to
ParticleSystemType
File
rules.ini
Section
[<ObjectType ID>]
Value
integer
When omitted
0

The count runs down one a frame, and the system stops emitting and begins to clear away when it reaches the end. Its last frame always throws a burst whatever SpawnSparkPercentage says, so a shower set to 1 is a single guaranteed burst and nothing more. Only the Spark behavior reads it.

HoldsWhat=MyWeldingSpark ; a ParticleType registered in [Particles]
ParticleCap=25
SparkSpawnFrames=20
SpawnSparkPercentage=.4
LightSize=25
OneFrameLight=true

Only the system’s first frame can cast the aging glow described under LightSize, and only when that frame happens to throw a burst, so a longer shower is not a longer light. The steady one-frame light the example sets instead is redrawn for as long as the system still holds a particle, which outlasts the count.
