I'm looking to use an ADD effect for generated fire in my game but it only really looks good when it is against a black background which makes sense because of the nature of the ADD effect. Anyone know a good work around for this? I've already attempted to create a black backing for the fire active but obviously this creates double the amount of actives for the same effect as being on a black background.

Anyone have a solution? Or a better way to generate fire? I want to create my own graphics for the fire to maintain the style of my game. Also I have realized that using ADD visually clumps together the graphics which is quite aesthetically appealing.

EXAMPLES

Against Black

Against light gray

Image

Against light gray with black backing objects

I've also seen this Flame thrower effect from this site

Anyone know if that is a good effect? What extensions and effect shaders does it use?

I explained how i did this kind of flamethrower effect in another topic. Is this something like you're looking for?

I currently only have one layer in use. The flamer effect is done with this kind of active object that scales larger, rotates in cw or ccw, creates smoke, and has "add" effect.

Here is version with the light effect:
edit: Ah fuck.. don't mind the lightness change in the ground in between player prone and the flames. The lighter ground there is a backdrop and a test area for the trees you see there.

The player in prone is semitransparent since have not been seen.

I've little knowledge of the ADD effect, but perhaps you can use the ADD effect in it's own layer, which is black, but that black is transparent to the user. Will that work?

Propably not. What might work is using alpha channels instead of add but its just "advanced semitransparent".

Hey thanks for the tips guys. Especially you Hapsi. I'm going to basically draw and animate most of my fire as well as using auto generated techniques as well. I'll be using the add effect and hopefully I won't ever use a light background.

I've got it! See the image:

Effect works as long as there is something black/"blackish" behind. In this case smoke. So make a black(ish) active the same size of the flame behind every active you use add effect in.
I have no need to change my flamer because it's never against a sky or anything very bright.
