Particles Scroll Factor

[Fredrik]

I am trying to get a particle emitter work in the middle of a screen where the camera is moving around on the map (like a win animation thingy), but I can't get it working. I can get the particles to work but they are stuck to specific coordinates and not centered in the screen/camera.

I can't set scrollFactor on particles and if I add it to a container with scrollFactor(0) then I get this error:

Uncaught TypeError: child.setScrollFactor is not a function

Anyone has any ideas on how to achieve this?
