ParticleEmitters not working?

by Ken Davis · in Torque Game Engine · 11/14/2004 (2:03 pm) · 5 replies

Hi again.
I have a hoverVehicle and I am trying to make the dust emitters and hoverbubble emitters work. In my vehicle datablock I have the following code.
dustEmitter = HoverEmitter;
triggerDustHeight = 0.0; // .0.5
dustHeight = 10.0; // 1.0
dustTrailEmitter = HoverEmitter;
dustTrailOffset = "0.0 -1.0 0.5";
triggerTrailHeight = 0.0; // 2.6
dustTrailFreqMod = 15.0;
and here is the code for the Emitters
datablock ParticleData(HoverParticle)
{
   textureName          = "~/data/particles/dustParticle.png";
   dragCoefficient      = 2.0;
   gravityCoefficient   = -0.1;
   inheritedVelFactor   = 0.1;
   constantAcceleration = 0.0;
   lifetimeMS           = 1000;
   lifetimeVarianceMS   = 0;
   colors[0]     = "0.46 0.36 0.26 1.0";
   colors[1]     = "0.46 0.46 0.36 0.0";
   sizes[0]      = 0.50;
   sizes[1]      = 1.0;
};

datablock ParticleEmitterData(HoverEmitter)
{
   ejectionPeriodMS = 10;
   periodVarianceMS = 0;
   ejectionVelocity = 1;
   velocityVariance = 1.0;
   ejectionOffset   = 0.0;
   thetaMin         = 5;
   thetaMax         = 20;
   phiReferenceVel  = 0;
   phiVariance      = 360;
   overrideAdvance = false;
   particles = "HoverParticle";
};

There are no errors in the console log but the particles just don't show.
Any ideas?
Thanks,
Ken

Not sure if it helps you any, but in the last month or so this had begun to pop up in my logs...

Could not register dust emitter for class: MediumMaleHumanArmor
Could not register dust emitter for class: MediumMaleHumanArmor
*** Initial Control Object



I've tried various emitters and settings and none of them change anything.

I haven't had tiime to figure out what happened though, or even if it's my fault or not. I suspect it's not because I never messed with any of that stuff before.

Are the emitter definitions before the MHMArmor definition?

In my code they are. I was getting errors similar to Gonzo's until I moved the emitter datablocks to the top. All of my other emitters work (water, splash, explosion, damage). Maybe the dust is working and I just can't see it.

I am trying to get my dust to work on a flying vehicle and I see it for a second then it is gone. I did notice however that you put your triggerdusthieght = 0.0;. That may be your problems because with a hove vehicle you are never at 0 altitude. you may want to replace this value with the value that you are hovering at or higher.

EDIT: found out what was wrong with my dust emitter only appearing for a second it was the settings in the datablock I had the lifetime set so it only emmited for that amount of time :).

If you have deleted all splash emitters and only use the dust you get
that error.
The splashemitter is a dust emitter :)
