Sub-emitters? #92

Closed digilocker closed 3 years ago

digilocker commented 5 years ago

I was wondering if there was an easier way of possibly adding sub emitters? I had an idea for a fireball effect with the fireballs being the main particles then a smoke trail following their position.

Had a trial yesterday and managed to get something working but required quite a few workarounds using timers to check the last particle added etc..

Any easier ways something similar could be achieved that I am missing, or is it a feature that could possibly be added?

I had considered making a subclass of Particle that owns an Emitter and updates it automatically, which should do the trick. Unfortunately, I currently don't have the time to do so, but that is the road that I would try to go down.

Awesome, thanks for the update, just wanted to make sure I wasn't missing a trick :)

This is now easy to make with the behaviors in release 5.0.0.

@andrewstart I'm looking through the behaviors. Would the recommended way of creating subemitters be through a second PointSpawn? I looked through a few examples in the README and I didn't see any that appear to use subemitters.

Say I wanted to add smoke to https://pixijs.io/particle-emitter/examples/flameUneven.html, what would be a strategy I could use with behaviors to achieve this?

There is no concept of subemitters in this library, you would instead use two Emitters as subemitters controlled by your "super emitter" that you create.

Thanks!

What in the 5.0.0 release made it easier to make that parent-sub1-sub2 emitter combination? It's not clear which of the behaviors listed would help with that. It probably exists (hence the earlier comment), but I'm missing a step!

edit: Ah, it might be that I need to create my own custom behavior and register it with Emitter.registerBehavior!

andrewstart commented 9 months ago

Yes, that's exactly it: you would make your own behavior that creates and manages another Emitter.

Thanks again for your help!
