I have been thinking, is it possible to put weather in Goldeneye, like the rain or snow in Perfect Dark? isnt it like fog? or is it a moving object.
this is a thing that i bet no one thought of.

Fog is an effect based on the z-buffer.
The z-buffer is a hardware feature (actually, given the architecture of the n64, it's a programmable microcode feature, but that's beyond the scope of this) which calculates a depth value for each of the display's pixels at render time.

http://en.wikipedia.org/wiki/Z-buffering

This is done so pixels from surfaces that are occluded by another surface aren't incorrectly displayed in the front.
Additionally, you can use the values of the z-buffer to apply a color shade to pixels, with the intensity of the shade depending on the value of Z.
The higher the z-value for a pixel, the more intense should be the color applied.
This way, pixels that are determined to be further away from the viewer by the z-buffer, are applied a more opaque coloring, which effectively produces the fog effect.

This differs a lot from the effects of rain and snow that appear in PD, which, from what I can tell, are actual objects floating in the game's 3d space, and not just some 2d or simple hardware effect. Also, they react to movement, changing the fall direction.

I'm not really the one to say if it can be done or whether there is a way to port them from PD or not, but definitelly they are not comparable to fog, that's for sure.

Is there a way to use an picture file and isert them as fog ? So that player see a picute. Or what is the air exactly ? Sometimes i am wondering how it is to play Depot or Statue on day, not at night ?

I think you only have to change the sky color, fog color and fog distance to turn depot from night to day. I believe that's done in the 29900 editor (or whatever is the number).
As I said, fog is not a texture, but a hardware effect.

[DF Ank1]

AH ok. I will check this later.

Modifying the sky, clouds and fog will help make a nighttime map look more like a daytime one. However, the way the map architecture is lit in the background file, may not make it so convincing. In some cases, you may need to go into the GoldenEditor and change the lighting, in order to really pull it off. It'd definitely be interesting to see a full transformation completed.

For rain and snow, I don't think we've even quite figured out how it is controlled in PD, yet. It could be possible to mimick the effect in GoldenEye, but we'd need to learn how to set it up first.

i think i am going to try to look at PD's memory and try try to figure at least ONE tiny part of it. but an object? in PD's memory cant you tell what objects are through some tedious hacking?

[Dragonsbrethren]

All we've figured out in PD is that there's an action that can toggle the snow on or off in Crash Site. It has no effect on the rain in Chicago, nor will it enable snow in any other stage tested, and the game somehow knows to turn snow off when you enter a cave without any apparent checks.

Speaking of snow, a pure white sky with thick fog makes for a very convincing snowstorm, even if you don't see any actual snow falling.

[DK25]

rain would be nice in the map im working on. im still going to try and figure this out, looking and looking until i destroy my PD ROM. lol

[Camaro]

Even if you can figure out how it is done in PD, how are you supposed to get it in to Goldeneye?

hmm, good question, not excactly easy isnt it?
well compare programming? i dont know.

[radorn]

Even if you never get to port it, you'll surely learn a lot about how things work which may lead to other achievements, only good things can come out of that

[Dragonsbrethren]

Yeah, we're certainly interested in knowing how PD's weather works for future PD projects.

[Camaro]

Yeah, it would be great to figure it out, but he was asking if it could be put into goldeneye

not to state the obvious but, before we put weather in Goldeneye, we need to figure out what exacly it is in PD. This is going to be easy
