As the title states, I want to change the angle of a particle emitter. I've looked into it, and it appears I have to cast my getEmitter(0) to ConfigurableEmitter, and then change the value angularOffset. The thing is, angularOffset is of type SimpleValue, which I don't know how to use.

I don't know much about Slick's particles, but the easiest solution would be to rotate your graphics context before rendering your particle emitters/systems:

Code:

g.rotate(centerX, centerY, angle);

That is what I have been doing, however I actually need to rotate the emitter, otherwise it looks strange.
