Creating Smoke/fog Programmatically.

[User137]

Smoke effect is easiest achieved with a 4-channel image, such as PNG. With image editing software such as free Gimp, you can make a semi-transparent blur of white-gray'ish colors. Have background of image fully transparent, and then paint with fading circle brush. In a game you only have to draw that on screen with no fancy tricks involved.

Souns like a plan, but if I do this, will it be animated? Smoke moving over the screen randomly? As tthis is the goal I am trying to achieve.
