Reversing the direction of particles?

[MrPickle]

I just need to get the particles coming towards me then, would negative velocity work?

Yep, should do.

It works, thanks.

If I edit the ejection velocity in the console and make it negative everything's fine but if the ejection velocity is set as the ParticleEmitterData is created it doesn't fire backwards :( Hold on idea! Didn't work.

This is a reoccurring problem and I'm faced with it constantly, I'm starting to believe that setting EjectionVelocity to a negative number just doesn't work, it ends up rounding up to a zero value and you get no movement apart from acceleration/gravity stuff.

The easiest way to get around this is to set the ConstantAcceleration value in the particle datablock to a negative number.
