Hey, community I search a ParticleSyste, for SFML 2
it must be a good System like spark but i need a little tutorial how to use it. thank you.

Why like SPARK but not SPARK?!

Ptlomej · « **Reply #2 on:** March 05, 2012, 06:53:34 pm »

I dont know how to integrate it into sfml2 :S

Its as simple as it gets!

If you know how to link the library etc, using it is piece of cake!

You just need to create a system, then update it and render it, there you go.

Tuning the system to what you want is just a matter of playing with it a little. That can be hard to get right, but particle systems always require some understanding or they are way too simple

Linking and compiling of SPARK 2 is very simple.
but how to integrate was the question ?

code samples ?

Some working code to look at.

Code: [Select]


        SPK::System::setClampStep(true,0.1f);			// clamp the step to 100 ms
	SPK::System::useAdaptiveStep(0.001f,0.01f);
	SPK::Ref<SPK::System> sparkSystem = SPK::System::create(true);

	renderer = SPK::GL::GLQuadRenderer::create(5,5);

	SPK::Ref<SPK::Group> effectgroup = sparkSystem->createGroup(4000);

	effectgroup->setName("Cool");
	//effectgroup->setRenderer(SPK::GL::GLPointRenderer::create(10));
	effectgroup->setRenderer(SPK::GL::GLLineRenderer::create(10, 5));

	mySphere = SPK::Sphere::create(SPK::Vector3D(300.f,300.f,0.f),4.0f);

	//effectgroup->setRenderer(renderer);
	effectgroup->setLifeTime(0.3,0.7);
	effectgroup->setColorInterpolator(SPK::ColorRandomInterpolator::create(SPK::Color(0,0,0,255),SPK::Color(0,15,0,255),SPK::Color(0,30,40,255),SPK::Color(50,0,0,255)));
	effectgroup->addEmitter(SPK::SphericEmitter::create(SPK::Vector3D(1.0f,0.0f,0.0f),0.0f,2*3.14159f,mySphere,true,-1,3000.0f,10.2f,15.5f));

	effectgroup->addModifier(SPK::Gravity::create(SPK::Vector3D(0.0f, -1,0.0f)));

Render code, i absolutely recommend to call ResetGLStates() after rendering your particles.

Code: [Select]

SPK::GL::GLRenderer::saveGLStates();
	glDisableClientState(GL_COLOR_ARRAY);
	glDisable(GL_TEXTURE_2D);
	glDisableClientState(GL_TEXTURE_COORD_ARRAY);
	sparkSystem->renderParticles();
	SPK::GL::GLRenderer::restoreGLStates();

Updating the system

Code: [Select]

sparkSystem->updateParticles(DeltaTime);

Can you guide yourself through it?

i will test and look at it if i get home im at work

You could also try my Thor particle system

Tutorial and api are the same ?

Nexus · « **Reply #9 on:** March 07, 2012, 08:52:40 pm »

No, sorry, I fixed the mistake.

Ptlomej · « **Reply #10 on:** March 07, 2012, 10:25:27 pm »

Can i use it seperate to sfml2 or musst i use the complete engine oô ?

Nexus · « **Reply #11 on:** March 08, 2012, 05:40:25 pm »

I'm not sure if I understand your question. Thor is no engine, you can use only the Particles module in addition to SFML.
