Simple Breath Fog Script

tpw · October 30, 2009

Hey guys!

I was kicking around making something like this for one of my missions and I decided to go for it. This script adds breath condensation to all units. The particles are created locally on each client so there is very little network traffic. I've included a version that has ACRE functionality so you can see condensation when people are talking. Should be 100% JIP, respawn compatible (also dead people don't breath ;) Although I didn't test it with respawn). I think I'll throw in ACE stamina at some point when I feel like it but it shouldn't be too hard to add if your up for it. Major props to Nou for some help with the per frame event handler.

You can change the drop interval ( _fog setDropInterval (0.01-random(0.005)); ) and particle color ( [[1,1,1, (.01+random(.03))], [1,1,1, 0.01], [1,1,1, 0]], ) to get the effect you want

To run add something like this to the init.sqf

if (!isDedicated) then
{
    	[] execVM "scripts\breath.sqf";	
};

Great work! I'm glad that other people are getting some use out of this!

I would like to see an auto-initialized version of this that kicks in at night and stops at day

AZCoder · November 21, 2009

This is fantastic. Set to 0.1 intensity, it works great with the cigarette mod :D

As far as day and night, I would suggest that it's actually cold air that makes foggy breath, and if someone wanted to get fancy they could take into account latitude (which is shown in CarlGustaffa's script), weather (cold rain front), and time of the year. I live in the desert and it's very unusual to see someone's breath even at night here in the Winter, but when I lived up north around 45 deg latitude it was common even in the daytime during the colder months.

Here's how I do it (reposted from page 2):

// Determine the angle of the sun (ie is it dark or not), adapted from CarlGustaffa 
[] spawn {while {alive player} do {
private ["_lat", "_day", "_hour", "_angle", "_isday"]; //Not 100% correct to BIS own code, but it does the trick.
_lat = -1 * getNumber(configFile >> "CfgWorlds" >> worldName >> "latitude"); //Arma latitude is negated for some odd reason.
_day = 360 * (dateToNumber date); //Convert current day to 360 for trigonometric calculations.
_hour = (daytime / 24) * 360; //Convert current hours to 360 for trigonometric calculations.
sunangle = ((12 * cos(_day) - 78) * cos(_lat) * cos(_hour)) - (24 * sin(_lat) * cos(_day)); 
//update every 5 minutes
sleep 300; 
};
};

private ["_unit"];
_unit = _this select 0;
_int = _this select 1; //intensity of fog (0 to 1)

while {alive _unit} do {
if (sunangle < 0) then {  // only fog breath if sun is below horizon
sleep (2 + random 2); // random time between breaths

_source = "logic" createVehicleLocal (getpos _unit);
_fog = "#particlesource" createVehicleLocal getpos _source;
_fog setParticleParams [["\Ca\Data\ParticleEffects\Universal\Universal", 16, 12, 13,0],

Here's how I do it (reposted from page 2)

but I mean as an auto initialized pbo

tpw · October 30, 2009

but I mean as an auto initialized pbo

Ah, I see. The problem is, which units to automatically deploy the breath script to.

Just player?

Just player's squad?

Just BLUFOR?

Every unit and civ?

As it stands, you can deploy it to the units of your choosing. I'll have a think and see if I can come up with something.

Angus S · June 8, 2011

I think every unit, or would that affect performance too much? How about making it as a module you can place in editor?

tpw · October 30, 2009

Every unit would (does, I've tried it) kill performance. I don't know how to make modules, but I could make it so that you can use a config file to choose between different modes of operation.

Angus S · June 8, 2011

That sounds great, I'll keep on eye on this thread for progress

falcon_565 · September 3, 2009

@AZCoder Unfortunately there's no easy way to pull the tempature from the world files where it is stored. I'm just running it on a per mission basis (i.e. adding it on missions were it should be cold and then modifying the effect so there's less during the day etc.)

@Tpw & Angus

I init it on all units which covers all units (not vehicles, animals etc). If you use my per frame event handler script it runs everything on the clients which is a very very minimal performance issue. I'm also going to add a screen to world function so it's only drawn if your looking at the unit.

Sounds like you're the man for the job Falcon_565! Pbo please :)

With regard to when to fog breath. It's related to the dew point http://en.wikipedia.org/wiki/Dew_point, which is itself a combination of temperature and humidity. Not sure how we'd go about extracting this info from the Arma world. So I just settle for fog at night!

AZCoder · November 21, 2009

@Falcon_565 - Certainly day/night works fine, I was just thinking how cool a complex script could be as I like to think big :) I was looking in the Effects module FSM for ideas, and BIS more or less uses day/night to determine when to spawn mist.

@tpw - Dew Point would explain the lack of foggy breath in Arizona, we have no humidity in the desert valley.

Explains why my breath can fog outside during the day when it's 25C and it has been pouring torrential summer rain every day for week!

I think that problem may be solved.

Now we have to get this script integrated with that mod...

Doolittle · January 7, 2002

Sorry to dig up an old thread, but I'm lovin' I44 and they use this script, which brought me to this post. Problem is breath goes away when someone respawns, new people come in, etc. So I re-wrote the script. I also figured out you don't need a logic as particles can attach automatically.

I tried to make the script not be too computation intense. It scans around the player and then if it finds someone, they start doing the cold breath.

Have the player run this once when they log in:

// Thanks to tpw for the particle params!
doobreath = {
private ["_pos", "_ps"];
sleep random 2;
_pos = _this selectionposition "neck";
while {_this distance player < 800 and alive _this and vehicle _this == _this and _pos select 2 != 0} do {
	_pos = _this selectionposition "neck";
	_ps = "#particlesource" createvehiclelocal getpos _this;
	_ps setparticleparams [["\ca\data\particleeffects\universal\universal.p3d", 16, 12, 13, 0], "", "Billboard", 0.5, 0.5, [_pos select 0, (_pos select 1) + 0.15, _pos select 2], [0, 0.2, -0.2], 1, 1.275, 1, 0.2, [0, 0.2, 0], [[1, 1, 1, 0.01], [1, 1, 1, 0.01], [1, 1, 1, 0]], [1000], 1, 0.04, "", "", _this];
	_ps setparticlerandom [2, [0, 0, 0], [0.25, 0.25, 0.25], 0, 0.5, [0, 0, 0, 0.1], 0, 0, 10];
	_ps setdropinterval 0.001;
	_this setvariable ["runningbreath", floor time + 5];
	sleep 0.5;
	deletevehicle _ps;
	sleep 2 + random 2;
};
};

[] spawn {
while {true} do {
	sleep 5;
	_near = nearestobjects [player, ["Man"], 500];
	{
		if (alive _x and vehicle _x == _x and _x getvariable ["runningbreath", -1] < time) then {
			_x setvariable ["runningbreath", floor time + 5];
			_x spawn doobreath;
		};
	} foreach _near;

Good stuff doolittle! I thought about something like this but am a) too lazy, b) too incompetent and c) i just play sinlge player editor mission with no respawning.

Oh~It looks nice!~

Let me have a try,hope it can give me surprise.

tpw · October 30, 2009

I know I've been a bit slack considering I started this thread, but I recently decided to try out Falcon_565's implementation and it is bloody fantastic. It's just amazing walking into a village on a cold day and seeing breath steaming out of civilians and even ambient life (I've got an ambient dog script, and they have foggy breath too!).

The question is, how do you know when it's cold?

Well, for those of you using Rube's incredible weather module http://forums.bistudio.com/showthread.php?131298-RUBE-Weather-Module, all you need to do is drop a couple of extra lines into Falcon's scripts and you can have the breath fog only come on when it's cold.

Just replace

_unit = _x;
if(alive _unit) then {

with

_unit = _x;
_temp = (RUBE_weatherEngine getFSMVariable "_temperature");
if((alive _unit) and (_temp < 5 )) then {

In this case, if the temperature drops below 5degC, the fog will kick in.

Thanks again Falcon_565!

I loaded Falcon_565's script via init.sqf and checked the execution with a hint "a" but I cannot see new brathing ingame on my men.

What could be the reason?

Strange, I'm running the non-acre version from my init.sqf and it's easy to see the breath fog, every 3-5 seconds or so. Are you using the acre or non-acre version? I don't MP so don't use acre.

I used the non acre. I put it in a folder "scripts_3rdparty" and called it from init.sqf for SP mission. hint "a" shows it gets called.

@xezon: Here is an mission with copy+pasted Code from tpw :http://www.fileuploadx.de/615413

Big THX to tpw for the script! Those little eyecatchers always enhance the whole Gameworld.

Hello to all!

I used the uploaded mission from tpw and it works great, but you have to make sure that you run the CBA, too.

- [my_breath_func, 0.1] call cba_fnc_addPerFrameHandler; - See the last line in the script

Have a look:

In my opinion, as also mentioned by Baraka, it is an awesome "little extra" for creating an atmosphere.

Very good job tpw, thx alot for such another great idea!

Cheers

McLupo

Implemented this, as usual great stuff, with some modifications in this, maybe these quick enhancements, or at least concepts, will prove useful for someone (particle params are changed for some reasons, but this is not about them. Tried to add breath frequency and params dependent on fatigue (measured by monitoring speed/velocity changes, not sure, what happens when unit is in vehicle, but if any problems occur here, should be sufficient additional condition for that in waitUntil)). It is set to be active only at 150 or less meters distance to save my weak CPU resources for other tasks.

To launch:

fogB = compile preprocessfile "FoggyB.sqf";

{
[_x,0.03] spawn fogB
}
foreach Allunits;

FoggyB.sqf:

// Foggy breath 20110122

private ["_unit"];
_unit = _this select 0;
_int0 = _this select 1; //intensity of fog (0 to 1)

while {alive _unit} do {

_ls = _unit getVariable "LastSpeed";
_spd = abs (speed _unit);
if (isNil "_ls") then {_ls = 0};
_mpl = 1 + (_spd/10);
if (_mpl > 1.2) then {_mpl = 1.2};
_int = _int0 * _mpl;
if (_int > 1) then {_int = 1};
if ((_ls > _spd) or (_spd < 1)) then {_ls = _ls - (0.25 + (random 0.15))} else {_ls = _ls + (0.35 + (random 0.15))};
if (_ls > 22) then {_ls = 22};
if (_ls < 0) then {_ls = 0};
_unit setVariable ["LastSpeed",_ls];

waitUntil
{
sleep ((2 + (random 2))/(0.6 + (_ls/5))); // random time between breaths
((_unit distance player) < 150)
};

_vl = velocity _unit;

_source = "logic" createVehicleLocal (getpos _unit);
_fog = "#particlesource" createVehicleLocal getpos _source;
_fog setParticleParams [["\Ca\Data\ParticleEffects\Universal\Universal", 16, 12, 13,0],
"", 
"Billboard", 
0.5, 
(0.3 + (_int/2)), 
[0,0,0],
[_vl select 0,(_vl select 1) + 0.2,(_vl select 2) - 0.2], 
1,1.25,1,0.75, 
[0, (0.4 + (_int/5))], 
[[1,1,1, _int], [1,1,1, 0.01], [1,1,1, 0]], 
[1000], 
1, 
0.04, 
"", 
"", 
_source];
_fog setParticleRandom [1, [0.01, 0.01, 0.01], [0.25, 0.25, 0.25], 0, 0.5, [0, 0, 0, 0.1], 0, 0, 10];
_fog setDropInterval 0.01;

_source attachto [_unit,[0,0.15,0], "neck"]; // get fog to come out of player mouth

sleep 0.5; // 1/2 second exhalation
deletevehicle _source;
}

Frequency should gradually and with some randomness increase when unit is moving quick enough, and slowly decrease, if unit is slows or is moving slow. Still not synchronized with breath sound.

Nice work mate, I will check it out ASAP.
