Wind affecting physic?

[WolvesSoulZ]

Is there anykind of addons that add random wind based on time?
Where the wind also have an effect on the physic props for exemple?

Like, we have a wind blast, barrel is pushed.

If there's none, is this possible to make? If it's, any indication on how I could make it? Or help.

Thanks

I Think is was possible with conna's Fan tool, but its broken for me, but i think people can fix it, ill go try...

I checked a bit the conna's fan stool, but, I wondered, would it be possible to include that into the init.lua file, so it happen randomly in the game?

Holy fucking hell...Wolves I freaking love you, you just gave me possibly the best Idea I have ever had. But, I actually need the same thing you do now..:psylon:

[WolvesSoulZ]

Hehe o.o, tho I wonder if anyone can make a thing like this xP

Surely it'd just be a case of applying force to everything in a single direction for a time, and then changing that direction randomly from time to time. And varying the strength of the force, and add some woosh woosh sounds when the force goes above a certain level.

Ohhh, pick me! I made something similar to this a while ago (not finished), but it has that kind of idea.

[lua]concommand.Add("wind",function()
local function ClampVector(vec,x,y,z)
vec.x = math.Clamp(vec.x,-x,x)
vec.y = math.Clamp(vec.y,-y,y)
vec.z = math.Clamp(vec.z,-z,z)
end

local WIND = {}
WIND.nextwind = 0
WIND.moverate = 0.1
WIND.dir = Vector(0,0,0)
WIND.strength = 10
WIND.currentstage = "gusty"
WIND.stage_run = 0
WIND.stages = {

intensity = 1,

Sound("ambient/wind/wasteland_wind.wav"),
Sound("ambient/wind/wind_snippet1.wav"),
Sound("ambient/wind/wind_snippet2.wav"),
},
soundwait = 10,
},

["medium"] = {
intensity = 2,
sounds = {
Sound("ambient/wind/wind_snippet3.wav"),
Sound("ambient/wind/wind_med1.wav"),
Sound("ambient/wind/wind_hit2.wav"),
Sound("ambient/wind/wind_moan2.wav")
},
soundwait = 7,
},

["gusty"] = {
intensity = 4,
sounds = {
Sound("ambient/wind/wind_hit1.wav"),
Sound("ambient/wind/wind_med2.wav"),
Sound("ambient/wind/wind_snippet2.wav"),
Sound("ambient/wind/wind_snippet5.wav"),
},
soundwait = 4,
},

intensity = 8,
sounds = {
Sound("ambient/wind/wind_hit3.wav"),
Sound("ambient/wind/windgust.wav"),

},
}

hook.Add("Think","BlowWind",function()
if CurTime() >= WIND.nextwind || CurTime() - WIND.nextwind > 20 then

local poss_stage = math.random(1,20)
if WIND.stage_run > 3 then
if poss_stage == 10 then
WIND.currentstage = "medium"
WIND.stage_run = 0

WIND.currentstage = "gusty"

local stageinfo = WIND.stages[WIND.currentstage]

ClampVector(WIND.dir,1,1,0.1)

local snd = table.Random(stageinfo.sounds)
for _,v in ipairs(player.GetAll()) do v:SendLua( "surface.PlaySound(\""..snd.."\")" ) end

local velocity_inc = 0

local orig_vels = {}
for _,v in ipairs(ents.FindByClass("prop_physics")) do orig_vels[v:EntIndex()] = v:GetPhysicsObject():GetVelocity() end

timer.Create("windMovement",WIND.moverate,SoundDuration(snd) / WIND.moverate,function()

velocity_inc = math.Clamp( velocity_inc + 1 / (SoundDuration(snd) / WIND.moverate), 0, 1 )
local objs = ents.FindByClass("prop_physics")
for _,v in ipairs( objs ) do
local index = v:EntIndex()
if not orig_vels[index] then orig_vels[index] = Vector(0,0,0) end
local phys = v:GetPhysicsObject()
if phys:IsValid() || ValidEntity(v) then
local vel = WIND.dir * WIND.strength * velocity_inc / ( math.Clamp(phys:GetMass(),5,10000) / 5 )
if phys:GetVelocity():Length() < orig_vels[index]:Length() then orig_vels[index] = phys:GetVelocity() end
phys:SetVelocity( orig_vels[index] + vel )
end
end

end)

WIND.nextwind = CurTime() + SoundDuration(snd) + math.Rand(0,stageinfo.soundwait)
WIND.stage_run = WIND.stage_run + 1
PrintTable(WIND)
end
end)
[/lua]

It moves all prop_physics in a certain direction with a certain velocity, and plays sounds according to the intensity of the wind.

I looked a bit onto it, fixed up a case of missing end) apparently, now it has no errors. It work as it should. (Edited, after fixing another thing)

Edit: Tho most of the props just push down on the grounds.
