Weather Question

[ChaosSlayerZ]

Looking at zone table in DB I noticed that there are 4 different chances for rain/snow.
Could someone tell me what does this mean? Are these 4 different types of rain that can happen? Like how strong it is?
And apparently it can Snow in Gfay? =)

Also, there are 4 different types of Fog setting - why 4? How do they combine with each other?

Thank You so much!

Check the source.

If I recall it selects one of the four "chances" and then performs a roll against that selected chance or something super weird?

Edit: On quick glance that's how it appears? There may be further reasoning though. I have always have had my weather/sky off :P

Ok guys, so I am looking at
https://github.com/EQEmu/Server/blob/master/zone/zonedb.cpp

I see this:

for (index = 0; index < 4; index++) {
zone_data->fog_red[index] = atoi(row[1 + index * 5]);
zone_data->fog_green[index] = atoi(row[2 + index * 5]);
zone_data->fog_blue[index] = atoi(row[3 + index * 5]);
zone_data->fog_minclip[index] = atof(row[4 + index * 5]);
zone_data->fog_maxclip[index] = atof(row[5 + index * 5]);
}


So are we combing different fog values together? Why, whats the significance? I noticed that for pretty much ALL zones all 4 fog values are the same.
Thanks!

Each of those properties is a array of 4 indices.

So you would get:

zone_data->fog_red[0] = atoi(row[1]);
zone_data->fog_red[1] = atoi(row[6]);
zone_data->fog_red[2] = atoi(row[11]);
zone_data->fog_red[3] = atoi(row[16]);

..by looping like that.

[ChaosSlayerZ]

Ok so we got those values.
But what does this mean in game?
If my fog RGB is set to 255 0 0 - its red right?
But then if fog1 and fog2 is set to something else - whats the end effect? Because I was changing values back and forth and I can't seem to notice any difference.

Also - multiple fog maxclips confusing me...

[Uleat]

Pretty sure they correspond to the weather system..but, that's only a guess from me - I've been wrong many times before :P

EDIT: I meant to include this too: https://github.com/EQEmu/Server/blob/master/zone/zone.cpp#L1301

Just shows that weather takes on one of four states, then intensity is applied for rain/snow.

[ChaosSlayerZ]

Thank you for your reply Uleat!
I trying hard to test the intensity but not sure how to force the client to show me different intensity for rain/snow.

I have tried to force this with a quest script like:



sub EVENT_SAY {

if($text=~/hail/i)
{quest::say("bla bla $name - $zoneweather");
}

if($text=~/rain/i)
{quest::say("bla bla $name - RAIN HARDER! $zoneweather");

quest::rain($zoneweather+5); }

if($text=~/snow/i)
{quest::say("bla bla $name - SNOW HARDER! $zoneweather");

quest::snow($zoneweather+5);}

}

I THINK its working - as I see snowflakes flying faster, but I can't say that I notice any changes on fog levels.


Also, by chance is zone clip exposed to Perl script?
I am asking because we have gm command #zclip, having it accessible via Perl function would be nice - we could then create Fog weather effect by lowering the clipplane.

[Uleat]

I definitely don't know enough about that to even make an educated guess...

I did see, in that function, that intensity seems to be its own value (1 - 10) and not part of the (0 - 3) array that controls which of the weather chances are used.

I'll keep my eyes open for any documentation concerning this.

[ChaosSlayerZ]

Thank you Uleat!

You can modify weather and stuff in Perl using quest::UpdateZoneHeader(ID, value).

void QuestManager::UpdateZoneHeader(std::string type, std::string value) {
if (strcasecmp(type.c_str(), "ztype") == 0)
zone->newzone_data.ztype = atoi(value.c_str());
else if (strcasecmp(type.c_str(), "fog_red") == 0) {
for (int i = 0; i < 4; i++) {
zone->newzone_data.fog_red[i] = atoi(value.c_str());
}
} else if (strcasecmp(type.c_str(), "fog_green") == 0) {
for (int i = 0; i < 4; i++) {
zone->newzone_data.fog_green[i] = atoi(value.c_str());
}
} else if (strcasecmp(type.c_str(), "fog_blue") == 0) {
for (int i = 0; i < 4; i++) {
zone->newzone_data.fog_blue[i] = atoi(value.c_str());
}
} else if (strcasecmp(type.c_str(), "fog_minclip") == 0) {
for (int i = 0; i < 4; i++) {
zone->newzone_data.fog_minclip[i] = atof(value.c_str());
}
} else if (strcasecmp(type.c_str(), "fog_maxclip") == 0) {
for (int i = 0; i < 4; i++) {
zone->newzone_data.fog_maxclip[i] = atof(value.c_str());
}
}
else if (strcasecmp(type.c_str(), "gravity") == 0)
zone->newzone_data.gravity = atof(value.c_str());

for (int i = 0; i < 4; i++) {
zone->newzone_data.rain_chance[i] = atoi(value.c_str());
}
} else if (strcasecmp(type.c_str(), "rain_duration") == 0) {
for (int i = 0; i < 4; i++) {
zone->newzone_data.rain_duration[i] = atoi(value.c_str());
}
} else if (strcasecmp(type.c_str(), "snow_chance") == 0) {

zone->newzone_data.safe_z = atof(value.c_str());
else if (strcasecmp(type.c_str(), "max_z") == 0)
zone->newzone_data.max_z = atof(value.c_str());

else if (strcasecmp(type.c_str(), "suspendbuffs") == 0)
zone->newzone_data.SuspendBuffs = atoi(value.c_str());

auto outapp = new EQApplicationPacket(OP_NewZone, sizeof(NewZone_Struct));
memcpy(outapp->pBuffer, &zone->newzone_data, outapp->size);
entity_list.QueueClients(0, outapp);
safe_delete(outapp);
}

Kingly_Krab thank you very much for sharing this.
I just need a little bit more help translating this into plain English =)
Lets say I only want to alter clip plan (not entire zone header) in real time how do I pass it my quest npc that tracks weather?

so I put
quest::UpdateZoneHeader(maxclip, 300)
into npc script, where ID and value can be my clipplane?

and then I have
void QuestManager::UpdateZoneHeader(std::string type, std::string value)
as independent function, right?

PS wanted to add that I don't see UpdateZoneHeader on official Perl functions list:
http://wiki.eqemulator.org/p?Ultimate_Perl_Reference&frm=Main

[Kingly_Krab]

It's not on the official list because it's undocumented (my fault). But all you need to do is put the following in a quest file: quest::UpdateZoneHeader("maxclip", 300);

[ChaosSlayerZ]

Thank you so much! You have no idea how many issues this solves for me! ;)

Another question for today
Playing around with fog color - I want to make bright yellow fog - using 255 255 0 does give me yellow color but it is still very dark with sky 0.
Any idea how to get bright yellow fog?

[ChaosSlayerZ]

Oh btw guys - in recent DB - Luclin skies are wrong in few places.
Nearly each Luclin outdoor zone suppose to have a unique sky texture - but in Db they all set to either 1 or 0. At the same time, some of these zone do show proper skies, while others don't. For example Maru Seru has proper violet sky, even though its set to texture 1. But Hallowshade Moore shows regular DAY time sky, while it suppose to have night sky with Norath:
http://everquest.allakhazam.com/scenery2/hollowshade-norrath.jpg

Shadeweaver's Thicket has proper sky with Norath in it, but it also rotates - is it suppose to? I thought Luclin doesn't rotate?

Also Umbral Plans apparently have an actual day and night cycle with Luclin in the sky =)
Whats going on?

Also, didn't Velious night skies had auroras? I maybe wrong here.

Something I always thought would be nice, is being able to adjust weather in certain parts of a zone. Why ? It rains in east commons tunnels. ;)
With a little script work, one could probably setup a proximity NPC with an EVENT_ENTER to shut the weather off, but weather for me trivial, lol

[ChaosSlayerZ]

Few other questions : in zone table, what are:
timezone, time_type, type, skylock?
Wiki doesn't have any info on those =(
