Controlling particle emission quantity

[YoshiDude]

Hi, everyone. I'm working on this weapon add-on thing and I'm trying to create an adequate particle emitter for a bullet's explosion. However, it appears to be creating way too many particles. How would I lower it?

Post the particle and particle emitter datablock.

Post the particle and particle emitter datablock.

Code: [Select]

datablock ParticleData(utaShrapnelParticle)
{
dragCoefficient      = 0.2;
gravityCoefficient   = 1;
inheritedVelFactor   = 1;
constantAcceleration = 0.0;
lifetimeMS           = 500;
lifetimeVarianceMS   = 55;
textureName          = "base/data/particles/chunk";
spinSpeed = 10.0;
spinRandomMin = -500.0;
spinRandomMax = 500.0;
colors[0]     = "0.2 0.2 0.2 0.9";
colors[1]     = "0.9 0.9 0.9 0.0";
sizes[0]      = 0.4;
sizes[1]      = 0.5;

useInvAlpha = false;
};
datablock ParticleEmitterData(utaShrapnelEmitter)
{
   ejectionPeriodMS = 1;
   periodVarianceMS = 0;
   ejectionVelocity = 3.0;
   velocityVariance = 3.0;
   ejectionOffset   = 0.0;
   thetaMin         = 0;
   thetaMax         = 80;
   phiReferenceVel  = 0;
   phiVariance      = 360;
   overrideAdvance = false;
   particles = "utaShrapnelParticle";

   uiName = "";
};

Increase ejectionPeriodMS (in utaShrapnelEmitter) or decrease lifetimeMS (in utaShrapnelParticle).

[YoshiDude]

Set ejectionPeriodMS higher in utaShrapnelEmitter or lifetimeMS lower in utaShrapnelParticle.

Could you explain what those variables affect?

Could you explain what those variables affect?

particleEmitterData.ejectionPeriodMS; delay in milliseconds between each new emitted particle
particleData.lifetimeMS; delay in milliseconds until the particle disappears

particleEmitterData.ejectionPeriodMS; delay in milliseconds between each new emitted particle
particleData.lifetimeMS; delay in milliseconds until the particle disappears

Thanks.
