I have a few particle effects that I would like to be in a circle shape in libgdx i.e. not a cone shape. I have done this by setting the direction of the particle effect from 0 to 360. The problem is that the particle effect is moving. So, as the emitters are moving, but not the particles themselves, the overall shape becomes conical. This could simply resolved by moving all the particles along with the particle emitters, but I can't fnd any way of doing this. I have considered drawing the effect to a Frame Buffer Object in one position, then draw the texture to each new position. However, this would mean I would have to flush the SpriteBatch each time a draw a particle effect, and that would be very expensive.
Is there any way to move the entire effect, with both the emitters and the particles?
Thannks in advance
