Hi, just wondering if anyone has a code for this:
PREDATOR CLOAK
Seen the movies? They were good, so does anyone have an invisibility code that looks like the PREDATOR's one? If it's not possible then it would be nice to have in a patch.
Thanks in advance

I've not seen that but if it's some sort of distortion, perhaps rainbow shading tand object then ghosting it will do? But that will require pixel shaders, which I don't have.

well, if darkbasic could handle transperancy but with light defraction it would be a breeze, but I dont think it can hadle that, infact, I think it is very unlikley to be able to handle anything like that in real time using any programing language.

But I have a trick that will do.

Make a texture of a few random white streeks on transparant background, blur it using gausian blur and save as PNG so that transperancy works. Use this as your model texture.

Voila... a barely visible textured object with a few hints of white to define the shape if you look well enough.

The more white, the less transparant.

Hmmm...interesting in theory, Hilmi, I've seen other games I believe have a nice cloak effect, does anyone know there names?

Starcraft has good cloaking effects

For UT (both versions, I believe), that is basically what it does.

As for Starcraft, it uses some kind of post processing thing that I'm not sure can be done in DB without the help of external .dll files, if at all.

when i hack no wait look into starcrafts MPQ i see a picture of a cloaked unit. its just a one colored picture. They programmed it so when the program sees that color it has that cloaking effect though i dont know how it works. It distorts the background i guess...

Halo's cloaking effect is very nie, they use some sort of light-warping apparently, same with War of the Monsters, but theyre both professional platform games, not DBPro creations... not saying DB is bad or anything, it just doesnt have the extreme flexibility needed for some stuff...

Is there some way to change the amount of ghosting? Like making it so transparent you can only barely see it even up-close? That might work, thats the way things are on Morrowind...

That's 'em, UT and HALO, I guess I'll find somet out on fading and ghosting etc, maybe there's away with coming up with the "jagged" distortion effect of a pred cloak. Anyway thanks guys, much appreciated.

Bump mapping? I heard somewhere thst it creates jagged effects. Could be used in conjunction with the FADE command?

That's good, but in a 3D game, you would be using up like 5000 RAM just to get the pictures of every area. I didn't make myself clear in my posts, so it's my fault really.

Ok, I got an idea but it WILL take FOREVER. First take the texture you're using for your guy and load it up on whatever paint program your using. Next zoom in untill your at the pixal level, now get you transparnce color and fill in every two pixals with it, this should give the efeect of a mostly trasparant character.
