empty : bool |
empty is set to true when there are no live particles left in the system.
You can use this to pause the system, keeping it from spending any time updating, but you will need to resume it in order for additional particles to be generated by the system.
To kill all the particles in the system, use an Age affector.
You can define a sub-set of particle groups in this property in order to provide them with stochastic state transitions.
每个 QtQuick::Sprite in this list is interpreted as corresponding to the particle group with the same name. Any transitions defined in these sprites will take effect on the particle groups as well. Additionally TrailEmitters, Affectors and ParticlePainters defined inside one of these sprites are automatically associated with the corresponding particle group.

paused : bool |
If paused is set to true, the particle system will not advance the simulation. When paused is set to false again, the simulation will resume from the same point it was paused.
The simulation will automatically pause if it detects that there are no live particles left, and unpause when new live particles are added.
It can also be controlled with the pause() and resume() 方法。
|
running : bool |
If running is set to false, the particle system will stop the simulation. All particles will be destroyed when the system is set to running again.
It can also be controlled with the start() and stop() 方法。
