Smoke/fire problem

[Humvee]

hi guys,
here's the deal
Im trying to make this wall of smoke appear very fast en big, the problem is that when i make a small script n place the smoke's (john's smoke effects) and i activate it, they all start firing up. BUT the bad thing is that they have to grow, i want them to start full sized.. so is it possible to make em like burn invisibly and then make em appear when i activate the script?
cheers

is the smoke effect made using the drop command? if so the particles can start as big as you like.

copy/paste the script here and we'll take a look.

That's the smoke addon config

[bedges]

ah right. this is an addon. hmmm, we have an addon board just for this sort of thing...

#moving...

i don't have experience with addons, but looking at the config i suspect cloudletGrowUp=0.400000; has something to do with it. trying changing it to 1.

[Humvee]

nop.. doesn't work
what were you on about? with the drop command? can you like create your own smoke with a script? (or is that just by placing smokegrenades?)

[bedges]

yes indeed. the drop command is what creates smoke and fire effects, and can be scripted. it's pretty advanced stuff, here's a taster:

create a marker on the map called mk_smoke. then cut and paste the following into notepad and save as "smoker.sqs" in the folder with your mission.

Code: [Select]

;smoke script

_x = getmarkerpos "mk_smoke" select 0
_y = getmarkerpos "mk_smoke" select 1
_color= [[0.5,0.5,0.5,0],[0.5,0.5,0.5,0.3],[0.7,0.7,0.7,0.7],[0.8,0.8,0.8,0.6],[0.9,0.9,0.9,0.5],[0.9,0.9,0.9,0.2],[1,1,1,0]]

#loop

_rub = random 0.025

drop ["cl_basic","","Billboard",1.5,10,[_x,_y,0],[0,0,0],0,1.25,1,_rub,[1,1+(random 3),2+(random 3)],_color,[0],0,0,"","",""]

~random 1

goto "loop"
then use [] exec "smoker.sqs" to run it.

[Humvee]

ok, no problem

now, how do i adjust the size? and also, this one starts slowely to, can't it go faster? or like be at full size from the start?
this one is very good for normal smoke effects going in the air, but can u also adjust the direction in goes in? i mean, let's say i want to keep it close on the ground but make it spread more around, how do i do that?  i hope i make myself clear here as i'm trying to reveal as least possible information about what im trying to creat

>boing< onto another board again

drop commands are pretty tricky to get just so, so you'll have to experiment. however, i'll get you started by showing you the numbers you'll have to tweak.

EDIT

right. the 'bits':

Drop [ShapeName, AnimationName, Type, TimerPeriod, LifeTime, Position, MoveVelocity, RotationVelocity, Weight, Volume, Rubbing, Size, Color, AnimationPhase, RandomDirectionPeriod, RandomDirectionIntensity, OnTimer, BeforeDestroy, Object]

and an ammended script which might be more suited to your purposes...

Code: [Select]

;smoke script

_x = getmarkerpos "mk_smoke" select 0
_y = getmarkerpos "mk_smoke" select 1
_color=[[0.5,0.5,0.5,0],[0.5,0.5,0.5,1],[0.5,0.5,0.5,0.7],[0.5,0.5,0.5,0.6],[0.5,0.5,0.5,0.5],[0.5,0.5,0.5,0.4],[0.5,0.5,0.5,0]]

#loop

;how much does the smoke move
_rub = random 0.001

;how big is the circle of smoke
_rad = 5 + (random 10)
_ang = random 360


drop ["cl_basic","","Billboard",1.5,10,[_x + (_rad*sin(_ang)),_y + (_rad*cos(_ang)),0.5],[random 2,random 2,0],0,1.275,1,_rub,[8],_color,[0],1,0.1,"","",""]

~0.1

goto "loop"

[Humvee]

yeah, just tell me what each bit of the "drop" line does, and i'll mess around with it myself
tnx dude

[bedges]

and as well as the last bit above, you may want to download the attached tutorial by Vektorboson - it's how i learned

wow, tnx dude, this will be pretty handy
