CAEmitterCell in a circular path not around the layer

[JulesMoorhouse]

I'm trying to create an effect where the particle is animated in a circular path, instead of around the rectangular layer.

I'm sure it must just be something simple, but I can't find any references to it.

I can find references to animating the particle in a circular animation around a rectangular path, but not the circular path.

Any ideas?

i don't think you can do that, that's a bit to deterministic for the emitter classes. I'd suggest to try an animation along a path. Try to make the emitterLayer very small and move it in a circle. Or try SpriteKit and try the same with an emitter node. The benefit of Spritekit is that it is easier to move things on a path.
