"make emitter stop emitting" animator

[andreee]

Hello, is there an animator way to do this? Because if i add delete animator to the particleSystemSceneNode, it kill all the particles (what i want is the emitter to stop emitting and when the last particle dies, i kill the whole node).
Is it possible somehow? I searched the forum, but din't find a solution.

Thank you

I suppose the following could work mostly (untested):

Code: Select all

particleSceneNode->getEmitter ()->setMaxParticlesPerSecond(0);
particleSceneNode->getEmitter ()->setMinParticlesPerSecond 

It won't remove the node, you would still have to do that if it's necessary as well (maybe with a timer).

edit: Or some hack - you could then add a custom IParticleAffector which would get the amount of active particles in it's affect function. So you could figure out in there if there are no particles left.

what about IParticleSystemSceneNode->setEmitter(0); ?
or will that kill the particles?

Yes, that would work, however by the time the emmiter gets to be destroyed, whole bunch of new emitters+particleNodes are created, so it would be uncomfortable to keep track of all existing particleNodes+their emmiters, since they all would have same lifetime.. Maybe some sort of custom animator..
