But keep in mind that a too big time step will introduce issues if the life spam of a particle is smaller than the time step. So it could be interesting to increase the time step to have less cycles to run. The more cycles you want, the slower the system will be to start. It will execute the particle animation loop 100 times with a time step set to 5 times faster than realtime. So if you set your system like this: system.preWarmCycles = 100 system.preWarmStepOffset: Gets or sets a value indicating the time step multiplier to use in pre-warm mode (default is 1).system.preWarmCycles: Gets or sets a value indicating how many cycles (or frames) must be executed before first rendering (this value has to be set before starting the system).To do so, you need to setup two properties: Starting with Babylon.js v3.3, you can now specify a pre-warming period to make sure your system is in a correct state before rendering.

Very useful if you want to create a one shot particle system with a specific targetStopDuration. Once stopped you can dispose of the particle system. You can also set the amount of time the particle system is running though live particles may continue after that time. If you want to reset a system to an empty state, you will also have to call particleSystem.reset() Note: that stopping a particle system will prevent the creation of new particles but the existing ones will continue. This value with override the particleSystem.startDelay field if set.

You can also delay start the particle system with particleSystem.start(3000). This value defines the delay in milliseconds. To delay a particle systems start, particleSystem.startDelay = 3000 can be set. Once completed you set the particle system in motion using particleSystem.start() Please note that you can use the ParticleHelper to create a default configured system with: (emitter). The particle system also requires a texture so that the particles can be seen and an emitter which sets the location and spread of the particles from a starting point. This sets the number of particles in the system (capacity). var particleSystem = new BABYLON.ParticleSystem('particles', 2000, scene) To perform this magic trick you first need to create a ParticleSystem object.
