i created this neat fire from this texture in the particle panel:
it just goes from yellow to red and Z-rotates, but creates a very good effect i think
if anyone has any ideas to make it less jarring to the eyes i will be glad to hear them

self.addForceGroup(f0)
also i have 2 questions
- is there any documentation on the use of sprite animations?
the manual just says than the option is there - is there a way to make the movement of the particles independent from the emitter?
