I am trying to create the particle entity, but I am having trouble with this. I do it the same way I did way back in EaaS but it doesnt seem to work anymore.

I want to create particle entity in C++. I know how to spawn it and so on, but later i want to add impulse to it, but if I physicalize it as PE_PARTICLE i can't GetPhysics () and impulse crashes. I tried to make it PE_RIGID but then attaching particle emitter does not work. It is attaching it to rigid entity, particle doesn't even show up. But in this case Action (impulse) works. I load particle and attach it to the entity by using LoadParticleEmitter (slot). How can I attach emitter to my entity and still be able to use Impulse action when particle follows entity and get collision ? I looked into projectile.cpp from game SDK and bullet. But I can't find the solution.

paricle just a sprite . dont have collider

I wouldn't post anything without previously reading that documents. It doesn't help me though. Still adding impulse doesn't work for PE_PARTICLE. also pe_params_particle have params.heading. But it doesn't work .

However I managed to separate my entity into 2 entities. First one is only collision listener, and second one is attached child - particle entity.

Anyways I am still looking for "cheaper" solution.

I think you create an entity use loadparticle() into a slot then physicalize the entity anyway you want. If you need this to be interacting with character bones it needs to be physicalize as particle.

I can't find loadparticle() method. Can you tell me a little bit more how to access it?

With LoadParticleEmitter(slotid, pEffect), I can load particle, but when I physicalize it later as PE_RIGID, particle doesn't show up.

Yes, I meant that function.
Then try physicalize by
SEntityPhysicalizeParams params;
params.type = PE_PARTICLE;
params.mass = mass;
params.pParticle = ParticleParams; a struct which should have surface_idx set at least, I guess. Surface type metal, wood etc.
GetEntity()->Physicalize(params);

PE_RIGID may be requires a mesh to be present in one of the slots already. Try loading a geometry too if you need rigid.

I tried both. Non of these allows me to use Action(impulse).
Thank you anyway.

CProjectile::SetAspectProfile(EEntityAspects aspect, uint8 profile)

if (m_pPhysicalEntity->GetType() == PE_PARTICLE)
{
pe_params_particle particle;
particle.heading = totalVelocity.GetNormalized();
particle.velocity = totalVelocity.GetLength();

m_pPhysicalEntity->SetParams(&particle, bThreadSafe);
}
else if (m_pPhysicalEntity->GetType() == PE_RIGID)
{
pe_action_set_velocity vel;
vel.v = totalVelocity;

m_pPhysicalEntity->Action(&vel, bThreadSafe);
}

looks like you can not add force to particle but can change speed

bool isParticle = (m_pPhysicalEntity != NULL) && (m_pPhysicalEntity->GetType() == PE_PARTICLE);
if (isParticle)
{
SetUpParticleParams(pOwnerEntity, projectileDesc.bulletPierceabilityModifier);

pe_params_flags pf;
pf.flagsOR = particle_no_impulse;
if (m_pPhysicalEntity)
m_pPhysicalEntity->SetParams(&pf);
}
