try using the particle designer and see if you can make the effect you want to make.
Once you have done that it’s just a matter of setting the values for the CCParticleSystemQuads class.
Have a look at the CCParticleExamples.cpp file to see what variables have to be set.
m_nEmitterMode ~~> defines the particle system mode as gravity based or size based.
modeA.gravity~~> defines the acceleration used for particles.
modeA.speed ~~> speed of the particles
modeA.speedVar~~> perterbation of speed of the particle to give different speeds for different particles.
m_fLife ~~> time for which the each particle will be shown for.
m_fLifeVar~~> perturbation of life time of particle..
