Fog editing

[nerovesper]

I was wondering if the sight of a unit can be modified by maybe JASS or any method?

something like this:

what I had in mind is this:

by creating dummy units that fogs up the main unit's sight behind and moving those units periodically. if this is the only way, can anyone help me what settings should set to let those dummy fog units so that they can block the sight of the unit.

but if there is a better way than this please do tell me.

+rep to those who help.

I tried it to do with line of sight blokers but unfortunately destructables can't be moved only killed and created new
this results in massive lags
and I don't know what makes the line of sight blocker actually block sight but I know which options DO NOT make it:
-shadow
-model file
-fat line of sight
-fog radius
-and now I became tired and I think it is caused by nothing but some hardcoded stuff but it works with custom destructables too

edit: you could make some very complicated trigger which moves regions behind every unit and fogs the region if it can't be seen by any other unit but it will lag too (not as laggy as this but still a lot)

edit2: I remember some anti maphack system which was quite powerful and could make shadows around a unit
maybe it will help you

however
map:

Will try it thanks ^^

ok... the option is called "Art - Occlusion Height" for Destructables
"Art - Occluder Height" for normal units (seems to be the same and now I'll google some dictionary to see what occluder means )

however "Occluder Height" only works if the unit is a building

your idea is interesting I think I am going to improve the map I attached before

I did this with actual fogmodifiers (MPI but not MUI), but your idea of blocking with units seems cool, i might have to try it.

You could do something like this:

function Trig_SightModefier_Actions takes nothing returns nothing
    local fogmodifier array SMArr
    local real uX
    local real uY
    local integer i = 0
    set uX = GetLocationX(GetUnitLoc(gg_unit_hrif_0000))
    set uY = GetLocationY(GetUnitLoc(gg_unit_hrif_0000))
    set SMArr[i] = CreateFogModifierRect(Player(0), FOG_OF_WAR_MASKED, Rect(uX-512.00, uY-512.00, uX+512.00, uY-32.00), true, true)
    call FogModifierStart(SMArr[i])
    call TriggerSleepAction(0.30)
    call FogModifierStop(SMArr[i])
endfunction

//===========================================================================
function InitTrig_SightModefier takes nothing returns nothing
    set gg_trg_SightModefier = CreateTrigger(  )
    call TriggerRegisterTimerEventPeriodic( gg_trg_SightModefier, 0.20 )
    call TriggerAddAction( gg_trg_SightModefier, function Trig_SightModefier_Actions )
endfunction

This just makes a block of fog under the unit, but you could do some calculations to figure out how to put an array of blocks in a circular fashion with a pie cut out.

units don't block fog after I moved them
not with Move Unit Instantly and not with SetUnitX/Y
Ideas?

of cause I gave them the stuff I just said but it seems like the Occluder Height is stuck at the position where it was created
so you have to create a new unit every time what causes leaks
-> the idea mentioned above is better

edit: units are crap.....the vision block is not instant, they leak and so on....

however here is the map
might be nice if you are adding something like "if unit moves then...." but like I said the JASS version above is better (but complicated)

 

[Cokemonkey11]

try making the dummies buildings and give them a good occlusion height? idk...

 

[nerovesper]

I'll try the Jass one first.

Make your unit have a sight range of 0. Then have an invisible, unselectable dummy unit with your desired sight range "follow" your unit around using a timer. When you need to change sight ranges, just change the dummy unit to another dummy unit with a different sight range.

as far as I got it (and as far as it is seen on this nice picture on the top) he wanted a triangle shaped view in front of a unit

ofc this idea with a little modification is great

edit: just tried it with far sight and it refuses to work properly without any reason oO

It took some time, but now I've got a working solution for you.

this is very nice but does it work with more then one unit? and why are u using a map unit instead of making a function with whichUnit?

edit:
here something with units
lags horrible
would be better with recyling
far sight would be even better
if far sight would work....
but it does not
and I am tired (1 o'clock in the morning at mine)
I'll continue later (not tomorrw )

I have only tested it with one unit, but i think it would lag horrible with multiple units. The fog circles could be increased in size and redused in number to compensate for this though. Now there is 40 or so fog circles updated 3 times a second, you could do it with 3-5 and get a decent result.
I'm using a map unit because I'm lazy and it's just an example
