Particle Engine: Couple Additions?
 

Having recently acquainted myself with the particle engine...I find that there are quite a few things that Graal's Developers would benefit from, pending them being added to the particle engine.

• The first of which, and quite possible the most important, is that there should be some kind of event and/or notification of an individual particle being destroyed. I.E., onParticleDestroyed(atx, aty, atz), that way we can have a few functions for things like splash ganis where rain drops hit the ground maybe.

• I've also been thinking sub-emitter functionality would be very useful for quite some time now. Allowing particles to emit other particles maybe very helpful when doing multiple emitters/particles for an effect.

I told you on Valikorlia RC that you should have a separate emitter do splash ganis/images randomly or so.

Having an event for every particle destroyed, which could be many particles a frame, would lag more than a 0.05 timeout loop.

And for the sub-emitter, is it not possible to find the location of a TParticle and just have another emitter emit relative to it?

Try this:

Alas, I suppose that will be efficient enough. I was hoping for something a bit more accurate i.e. at the exact drop point, but alrighty then.

I will make sure to do so.

There are dropemitter and dropwateremitter, those can be used to show rain drops, particles can also use ganis.

Forgive me but what do dropemitter and dropwateremitter actually do? o.o The wiki isn't clear.

Well they emit particles on the spot where a particle is landing
