Question is how to define a non-rectangular shape for emitter node position range?
By position range I mean this:
emitter.particlePositionRange = CGVectorMake(50,75);
Is there some workaround to make this area triangular instead of rectangular?

nope, at best you can use multiple emitters with smaller ranges – CodeSmile Jul 01 '14 at 16:53

So am I missing the point here, or this kind of 'problem' is allways solved in this way (with multiple emitters creating aproximate shape) ? Thank you. – Whirlwind Jul 01 '14 at 17:14

always like that, non-rectangular-shape-based emitters aren't very common actually – CodeSmile Jul 01 '14 at 17:36
