Level effects
 

There are two effects I am trying to achieve.

1. Darkening screen.
2. Fog effect. (I've seen this on Maloria I believe.)

My question is what is the best (most efficient) way to get a darkened screen effect?
Also, for the fog effect, should I run that through a gani, moving image, or what?

1. use setEffect(r,g,b,a) on clientside. rgb is the normal red, green, blue thingy and a is for alpha, those 4 are all reaching from 0 to 1, meaning you can use stuff like 0.75 etc
2. use particles. this can create particles which might help you to understand the creation of particles
