   Hello,
   I've made a particle system:
   

   emitter = [[CCParticleSystem alloc] initWithTotalParticles:413];
   		[emitter setEmitterMode: kCCParticleModeGravity];
   
   		emitter.texture = [[CCTextureCache sharedTextureCache] addImage:@"star.png"];
   
   		emitter.position = ccp( 350, 130 );
   		[emitter setEmissionRate:10];
   		[emitter setGravity:ccp(1.23,0.28)];
   		[emitter setAngle:338];
   		[emitter setSpeed:12.0];
   		[emitter setLifeVar:8];
   		[emitter setStartSize:26.0];
   		[emitter setStartSizeVar:5.0];
   		[emitter setEndSize:14.0];
   		[emitter setEndSizeVar:33.0];
   		[emitter setLife:10];
   		[emitter setAngleVar:337];

   Nothing happen :)
   If i change the first line to

   emitter = [[CCParticleFireworks alloc] initWithTotalParticles:413];

   or something else, i see the particles, but i want to create a particlesystem without any preselected templates.

   How to start the particle system ?

   I had a similar problem today.

   Look at the macros in CCParticleExamples.h.

   As soon as I replaced "CCParticleSystem" with the macro "ARCH_OPTIMAL_PARTICLE_SYSTEM" it worked.

   Thank you for your quick reply.
   I looked in the ParticleExamles.h but i cant find any CCParticleSystem entry to replace:

   CCParticleExamples.h
   

   #import "CCPointParticleSystem.h"
   #import "CCQuadParticleSystem.h"
   
   //! A fire particle system
   @interface CCParticleFire: CCQuadParticleSystem
   {
   }
   @end
   
   //! A fireworks particle system
   @interface CCParticleFireworks : CCQuadParticleSystem
   {
   }
   @end
   
   //! A sun particle system
   @interface CCParticleSun : CCQuadParticleSystem
   {
   }
   @end
   
   //! A galaxy particle system
   @interface CCParticleGalaxy : CCQuadParticleSystem
   {
   }
   @end
   
   //! A flower particle system
   @interface CCParticleFlower : CCQuadParticleSystem
   {
   }
   @end
   
   //! A meteor particle system
   @interface CCParticleMeteor : CCQuadParticleSystem
   {
   }
   @end
   
   //! An spiral particle system
   @interface CCParticleSpiral : CCQuadParticleSystem
   {
   }
   @end
   
   //! An explosion particle system
   @interface CCParticleExplosion : CCQuadParticleSystem
   {
   }
   @end
   
   //! An smoke particle system
   @interface CCParticleSmoke : CCQuadParticleSystem
   {
   }
   @end
   
   //! An snow particle system
   @interface CCParticleSnow : CCQuadParticleSystem
   {
   }
   @end
   
   //! A rain particle system
   @interface CCParticleRain : CCQuadParticleSystem
   {
   }
   @end

   What i should replace ?

   Well I got the latest 0.99.5 from github. It looks like this:

   // build each architecture with the optimal particle system
   
   // ARMv7, Mac or Simulator use "Quad" particle
   #if defined(__ARM_NEON__) || __MAC_OS_X_VERSION_MIN_REQUIRED || TARGET_IPHONE_SIMULATOR
   	#define ARCH_OPTIMAL_PARTICLE_SYSTEM CCParticleSystemQuad
   
   // ARMv6 use "Point" particle
   #elif __arm__
   	#define ARCH_OPTIMAL_PARTICLE_SYSTEM CCParticleSystemPoint
   #else
   	#error(unknown architecture)
   #endif
   
   //! A fire particle system
   @interface CCParticleFire: ARCH_OPTIMAL_PARTICLE_SYSTEM
   {
   }
   @end
