Spark2 Irrlicht integration

Messages : 53 Date d'inscription : 2012-06-23

I have been using spark particle engine integrated with irrlicht to leave trails behind moving objects and lately i jumped to spark 2 and i can't replicate the old behaviour.

Code:: SPK::Ref<SPK::IRR::IRRQuadRenderer> particleRenderer = SPK::IRR::IRRQuadRenderer::create(device);
particleRenderer->setTexture(device->getVideoDriver()->getTexture("res\\explosion.png"));
particleRenderer->setTexturingMode(TEXTURE_MODE_2D);
particleRenderer->setScale(2.5f,2.5f);
particleRenderer->setBlendMode(BLEND_MODE_ALPHA);
particleRenderer->setAtlasDimensions(2,2);
particleRenderer->enableRenderingOption(SPK::RENDERING_OPTION_DEPTH_WRITE,false);

// Model
// Emitter
particleEmitter = SPK::SphericEmitter::create(Vector3D(0.0f,0.0f,-1.0f),0.1f * PI,0.1f * PI);
particleEmitter->setZone(Point::create(Vector3D(0.0f,0.02f,0.0f)));
particleEmitter->setFlow(10);
particleEmitter->setForce(0.1f,0.5f);
particleSystem = SPK::System::create(false);
// Group
SPK::Ref<SPK::Group> particleGroup = particleSystem->createGroup(1100);
particleGroup->addEmitter(particleEmitter);
particleGroup->setRenderer(particleRenderer);
particleGroup->setParamInterpolator(SPK::PARAM_TEXTURE_INDEX,SPK::FloatRandomInitializer::create(0.0f,4.0f));
particleGroup->setLifeTime(80.0f,0.0f);
particleGroup->setRadius(1.15f);
//particleGroup->setGravity(gravity);

particleSystem->enableAABBComputation(true);
particleSystem->initialize();

this->Powerlvl = 1000;
irr::scene::CSPKParticleSystemNode* system = new irr::scene::CSPKParticleSystemNode(particleSystem,Node, device->getSceneManager(),false);
system->setAutomaticCulling(EAC_OFF);
system->setID(42);

this is my currend code and it's just not working.

Hello,

What was your old code ?

Code:: IRRQuadRenderer* particleRenderer = IRRQuadRenderer::create(device);
particleRenderer->setTexture(driver->getTexture("res\\explosion.png"));
particleRenderer->setTexturingMode(TEXTURE_2D);
particleRenderer->setScale(2.5f,2.5f);
particleRenderer->setBlending(BLENDING_ALPHA);
particleRenderer->setAtlasDimensions(2,2);
particleRenderer->enableRenderingHint(DEPTH_WRITE,false);

// Model
Model* particleModel = Model::create(FLAG_RED | FLAG_GREEN | FLAG_BLUE | FLAG_ALPHA |FLAG_TEXTURE_INDEX);
//particleModel->setParam(PARAM_ALPHA,0.8f); // constant alpha
particleModel->setLifeTime(0.0f,80.0f);
particleModel->setParam(PARAM_TEXTURE_INDEX,0.0f,4.0f);
// Emitter
particleEmitter = SphericEmitter::create(Vector3D(0.0f,0.0f,-1.0f),0.1f * PI,0.1f * PI);
particleEmitter->setZone(Point::create(Vector3D(0.0f,0.02f,0.0f)));
particleEmitter->setFlow(10);
particleEmitter->setForce(0.1f,0.5f);

// Group
Group* particleGroup = Group::create(particleModel,1100);
particleGroup->addEmitter(particleEmitter);
particleGroup->setRenderer(particleRenderer);
//particleGroup->addModifier(obstacle);
particleGroup->setGravity(gravity);
particleGroup->enableAABBComputing(true);

particleSystem = IRRSystem::create(Node,smgr);
particleSystem->addGroup(particleGroup);
particleSystem->enableAABBComputing(true);

this was my old code and i was using something like spark 1.5 i think

Sorry, forgot to ask before: what is "not working" ?

PS: setLifeTime(80,0) is not correct, because its setLifeTime(0,80) Wink

. BTW, it does not changes a lot of things.

I was about to post a video of the effet i was creating befor but i need to be a member for more then 7 days ....

w------------ww.youtube.com/watch?v=gSwFZu42MHY&feature=g-upl

This is what i was doing with the previous version now i'm unable to recreate the effect ethier the particles don't show up at all or they are in the ship local space.

Hi,

If you dont want particles to be in system's space, pass true to the constructor as 3rd parameter.

Moreover it is more advised, as the documentation states, to use the constructor of CSPKParticleSystemNode that creates the SPARK system for you :

Code:: CSPKParticleSystemNode(ISceneNode* parent,ISceneManager* mgr,bool worldTransformed = true,bool initialize = true,s32 id=-1);

Then you have createSPKGroup(int) to create a group and attach it to the system and getSPKSystem to retrieve the underlying system.

For gravity, you can add it in SPARK 2 using a Modifier which is called Gravity

Even when passing true the particle don't show up at all

i swaped the values and tryed using you way to set it up

Code:: irr::scene::CSPKParticleSystemNode* system = new irr::scene::CSPKParticleSystemNode(Node, device->getSceneManager(),true,true,42);
//system->initializeSPK();
system->setParent(this->Node);
//Vector3D gravity(0.0f,0.0f,0.0f);

SPK::Ref<SPK::IRR::IRRQuadRenderer> particleRenderer = SPK::IRR::IRRQuadRenderer::create(device);
particleRenderer->setTexture(device->getVideoDriver()->getTexture("res\\explosion.png"));
particleRenderer->setTexturingMode(TEXTURE_MODE_2D);
particleRenderer->setScale(2.5f,2.5f);
particleRenderer->setBlendMode(BLEND_MODE_ALPHA);
particleRenderer->setAtlasDimensions(2,2);
particleRenderer->enableRenderingOption(SPK::RENDERING_OPTION_DEPTH_WRITE,false);

// Model
SPK::Ref<SPK::Sphere> explosionSphere = SPK::Sphere::create(SPK::Vector3D(0.0f,0.0f,0.0f),0.4f);
// Emitter
particleEmitter = SPK::SphericEmitter::create(Vector3D(0.0f,0.0f,-1.0f),0.1f * PI,0.1f * PI);
particleEmitter->setZone(explosionSphere);
particleEmitter->setFlow(10);
particleEmitter->setForce(0.1f,0.5f);
// Group
SPK::Ref<SPK::Group> particleGroup = Group::create(1100);
particleGroup->addEmitter(particleEmitter);
particleGroup->setRenderer(particleRenderer);
particleGroup->setParamInterpolator(SPK::PARAM_TEXTURE_INDEX,SPK::FloatRandomInitializer::create(0.0f,4.0f));
particleGroup->setLifeTime(1.0f,80.0f);
particleGroup->setRadius(1.15f);
system->addSPKGroup(particleGroup);
//particleGroup->setGravity(gravity);

this->Powerlvl = 1000;
system->setAutomaticCulling(EAC_OFF);

and the particle just don't show up at all

Ok, i ll try to make your code work and come back to you. Which version of Irrlicht do you use ?

Messages : 53 Date d'inscription : 2012-06-23

1.8.0 in the svn

I think i hit the jack pot.

i tryed compiling irrlicht with suport for 16 texture and then i started having issue and even when rolling back the only change i made i still get this when trying to compile my project

After a while i came back to spark and tested it some more it would seem particle are only emited in local space

Messages : 53 Date d'inscription : 2012-06-23

est que je devrais ouvrir un topic dans la section francais?

Car il sempblerai que le parametre pour emetre les particule dans le "worldspace" ne fonctione pas et je ne comprend pas pourquoi

Subject: Re: Spark2 Irrlicht integration Mon Jul 23, 2012 4:49 am

There is a small bug in CSPKParticleSystem: 2 boolean parameters are inverted in the constructor between header and source. It's fixed on my local repo, but not commited.

For the moment, you have to do the following:

Code:: // Notice the 'true' added here, it's for the parameter 'initialize'.
// ||||
// vvvv
system = CSPKParticleSystemNode(parentSceneNode,smgr, true,worldTransformed);

i have always used it this way but no the bug is even worst

Code:: irr::scene::CSPKParticleSystemNode* system = new irr::scene::CSPKParticleSystemNode(NULL, device->getSceneManager(),false,true,43);
irr::scene::CSPKParticleSystemNode* system = new irr::scene::CSPKParticleSystemNode(NULL, device->getSceneManager(),true,true,43);

this no particle show up at all

Code:: irr::scene::CSPKParticleSystemNode* system = new irr::scene::CSPKParticleSystemNode(NULL, device->getSceneManager(),false,false,43);
irr::scene::CSPKParticleSystemNode* system = new irr::scene::CSPKParticleSystemNode(NULL, device->getSceneManager(),true,false,43);

particle show up in local space

anyone suceedded at having a moving node leave particle behind as it move with spark 2? because for now this is a complete mistery

Subject: Re: Spark2 Irrlicht integration Tue Jul 31, 2012 3:27 am

Can you post the whole code please ? Will test next week (for the moment I'm too busy...).

I already posted the full code earlier the particle scene node is only a children of a moving node.

if you mean i should post my entire project i don't think you wan me to post my 10 000 line engine

Code:: irr::scene::CSPKParticleSystemNode* system = new irr::scene::CSPKParticleSystemNode(NULL, device->getSceneManager(),true,false,43);

should be

Code:: irr::scene::CSPKParticleSystemNode* system = new irr::scene::CSPKParticleSystemNode(NULL, device->getSceneManager(),true,true,43);

(the last boolean is for initialization of the inner SPK::System).

With 'worldTransformed = true', you have to set the transform to the scene node, not the SPK::System.

Messages : 53 Date d'inscription : 2012-06-23

well this should be taken care of here

Code:: system->initializeSPK();
system->setParent(Node);

when the particle become child to an other node ut it does not work and nothing is shown

how ever disabeling world transformed get me some particle drawn in the ship local space

anywayi changed the code to make initialisation here and assing parent here to

now this show particle in node local space

Code:: irr::scene::CSPKParticleSystemNode* system = new irr::scene::CSPKParticleSystemNode(Node, device->getSceneManager(),false,true,43);

this sow nothing

Code:: irr::scene::CSPKParticleSystemNode* system = new irr::scene::CSPKParticleSystemNode(Node, device->getSceneManager(),true,true,43);

O_o ? I tested it though...

Can you post the portion of the code which controls the node, or system transform ?

Some dumb questions...: did you update the dlls? have you tried to recompile ?

Messages : 53 Date d'inscription : 2012-06-23

the transformation is done by a physic engine

also i recompiled the spark2 dll but they are the exact same weight and i didnot see any aditional file compiled

unlesss there is a bug in my way of initiating the rest of the system

Subject: Re: Spark2 Irrlicht integration Sat Aug 25, 2012 4:54 am

granyte wrote:: the transformation is done by a physic engine

OK, but how do you transfer it to the effect? You set the scene node transform (setPosition, setRotation & co), or the SPK::System transform ?

granyte wrote:: also i recompiled the spark2 dll but they are the exact same weight and i didnot see any aditional file compiled

Only two lines were changed, no files added or removed in this revision, should be normal.

I tested the revision with the Irrlicht test, making the CSPKParticleSceneNode rotating around the Y axis:

Code:: float x = cos(time * irr::core::PI);
float z = sin(time * irr::core::PI);
irrSystem->setPosition(irr::core::vecvtor3df(x,0.0f,z));

You can test it if you want.
