ParticleSystem setDirection issue

[codinghands]

I'm trying to get a ParticleSystem to emit in a single direction, with a spread around a given point, something like:

I've set direction to 39deg in rad, and spread to 78deg in rad, but the system is emitting both toward the top left and the bottom right.

How can I configure the system to only emit towards the top left?

Ah not to worry, I had setSpeed to neg and pos values causing this. Seems to be fixed by changing both to neg values.

Cheers.
