How to make snow fall?

[Brodster55]

How could I make snow fall from the sky?

[Gbps]

Using particle effects.

[sp]Or ask me for my addon[/sp]

[Brodster55]

Okay, how do you make particle effects?

-Snip- im a moron.

[Brodster55]

Why wasnt it working noforgivin?

[noforgivin]

Because i was being stupid ?

I've made a nice big red firework now.. now to make it appear at the trace of the payer view.. i wonder.

[Brodster55]

Oh.. I made the snow, but i dont know how to make it all spread out when it starts. It starts in a little circle.

[lua]
local centr = Vector(1.91,89.58,494.33)
local em = ParticleEmitter(centr)
for i=1, 20 do
local part = em:Add("sprites/light_glow02_add",centr)
if part then
part:SetColor(255,255,255,math.random(255))
part:SetVelocity(Vector(math.random(-1,1),math.random(-1,1),math.random(-1,1)):GetNormal() * 20)
part:SetDieTime(500)
part:SetLifeTime(200)
part:SetStartSize(10)
part:SetEndSize(0)
part:SetGravity(Vector(0,0,-200))
end
end
em:Finish()
[/lua]

[noforgivin]

to make it a bigger "bang" change that *20 to *1000 and mess with the Velocity.

[lua]
if CLIENT then
function startthesnows()
timer.Stop("snowtimerz")
local em = ParticleEmitter(Vector(0,0,100))
timer.Create("snowtimerz",0.1,0,function()
for i=1, 50 do
local par = em:Add( "particle/snow",LocalPlayer():GetPos() + Vector(0,0,1000) )
par:SetVelocity( Vector(math.random(-700,700),math.random(-700,700),math.random(-100,-30)) )
par:SetDieTime(20)
par:SetStartAlpha(0)
par:SetEndAlpha( 255 )
par:SetStartSize( 4 )
par:SetEndSize( math.random(0,3) )
par:SetColor(255,255,255 )
par:SetRoll( math.random( 0, 360 ) )
end
end)
end
else
AddCSLuaFile( "spensnow.lua" )
function dafurztspwn(ply)
ply:SendLua("startthesnows()")
end

hook.Add( "PlayerInitialSpawn", "playtehsnow", dafurztspwn )
end[/lua]

Put it in your server's lua/autorun folder and name it spensnow.lua (or you can rename it to whatever and change the AddCSLuaFile)

I'm sure people have done better, but that's my attempt at snow.

Ignore the crappy function names. It was just to practice the particle emitter.

[noforgivin]

This is what i've achieved.

Here's some pics.

I have them bound to keys.

[Brodster55]

I put this:
[lua]
function startthesnows()
timer.Stop("snowtimerz")
local em = ParticleEmitter(Vector(0,0,400))
timer.Create("snowtimerz",0.1,0,function()
for i=1, 50 do
local par = em:Add( "particle/snow",LocalPlayer():GetPos() + Vector(0,0,1000) )
par:SetVelocity( Vector(math.random(-700,700),math.random(-700,700),math.random(-100,-30)) )
par:SetDieTime(20)
par:SetStartAlpha(0)
par:SetEndAlpha( 255 )
par:SetStartSize( 4 )
par:SetEndSize( math.random(0,3) )
par:SetColor(255,255,255 )
par:SetRoll( math.random( 0, 360 ) )
end
end)
end
[/lua]

into my cl_init.lua and i dont see anything

[noforgivin]

-SNIP- Made some errors.

Now works fine for me.

[lua]
function startthesnows()
timer.Stop("snowtimerz")
local em = ParticleEmitter(Vector(0,0,400))
timer.Create("snowtimerz",0.1,0,function()
for i=1, 50 do
local par = em:Add( "particle/snow",LocalPlayer():GetPos() + Vector(0,0,1000) )
par:SetVelocity( Vector(math.random(-700,700),math.random(-700,700),math.random(-100,-30)) )
par:SetDieTime(20)
par:SetStartAlpha(0)
par:SetEndAlpha( 255 )
par:SetStartSize( 4 )
par:SetEndSize( math.random(0,3) )
par:SetColor(255,255,255 )
par:SetRoll( math.random( 0, 360 ) )
end
end)
em:Finish()
end

concommand.Add( "snow", startthesnows )
[/lua]

run the lua file or however your doing it then do snow in console

[editline]01:07AM[/editline]

Also i got a really nice effect with this.

[lua]
function startthesnows()
timer.Stop("snowtimerz")
local em = ParticleEmitter(Vector(0,0,400))
timer.Create("snowtimerz",0.1,0,function()
for i=1, 2000 do
local par = em:Add( "particle/snow",LocalPlayer():GetPos() + Vector(0,0,1000) )
par:SetVelocity( Vector(math.random(-700,700),math.random(-700,700),math.random(-100,-30)) )
par:SetDieTime(20)
par:SetStartAlpha(0)
par:SetEndAlpha( 255 )
par:SetStartSize( 6 )
par:SetEndSize( math.random(0,6) )
par:SetColor(255,255,255 )
par:SetRoll( math.random( 0, 360 ) )
end
end)
em:Finish()
end

concommand.Add( "snow", startthesnows )
[/lua]

With Post proc too.

With the script I posted, it will start the snow for players as soon as they join. Not sure why you changed it.

I just made the snow heavier, more realistic.

[Skapocalypse]

Ah cool cool, I haven't really messed with particles too much. They're pretty fun though and you can make really cool things on accident :)

[noforgivin]

Yeh!, i have only just learned geteyetrace from this!
