Particle doesn't follow pawn after Pawn.AttachComponent(ParticleSystemComponent)

Legacy UDK Programming and UnrealScript
1

Hi everyone. This question is regarding UDK–not UE4. (It seems like we have to say that now for the people who don’t see what forum they’re in.) I’m able to spawn a particle system component. I can see it just fine. But when the pawn moves, the particle system component stays put.

This is the code that spawns the particle system component:



var() ParticleSystem Particle;
var ParticleSystemComponent ParticleComponent;
var Pawn AttachedPawn;

function SpawnParticleSystem(Pawn P)
{
	ParticleComponent = WorldInfo.MyEmitterPool.SpawnEmitter(Particle,P.Location,P.Rotation);
	P.AttachComponent(ParticleComponent);
	AttachedPawn = P;
}

“Particle,” the first var I declare is an archetype that I set beforehand. I’m using this class to keep track of status effects on the characters in my game and each status effect has its own particle system. Except for that, I think everything else here is pretty self-explanatory.

Any idea what I need to do to get the particle system component to follow the pawn I’m trying to attach it to?

I figured it out. You can attach the particle system component at the same time you have the emitter pool spawn it:



ParticleComponent = WorldInfo.MyEmitterPool.SpawnEmitter(Particle,P.Location,P.Rotation,P);

And using “WorldInfo.MyEmitterPool.SpawnEmitterMeshAttachment” instead?

I haven’t tried using SpawnEmitterMeshAttachment. I suppose there’s some distinction between attaching to the pawn (or any actor, really) and attaching to the pawn’s (or other actor’s) mesh. Mostly I just needed an emitter at the same location, and SpawnEmitter seems to work well enough for that.
