One-way visibility blocker?

[Antares]

Hello,

1.) is it possible to imitate the visibility blocking done by the stardard blizzard cliffs without using them?
so, in essence, can you block visibility into one direction, but not in the other direction.

see this screenshot to understand what i mean:

i made the vis blockers visible with these fancy eye effects.

2.) can pathing blockers and visibility blockers become a performance whore, if too many are used? i estimate, that the final map will have ~4000 blockers. or can they significantly increase loading time? or significantly increase map size? anything bad.

What about player-specific fog-of-war settings? I'm not even sure if you can do this without a desync but have you tried?

Did you do the terrain for this? I was so intrigued I actually right-clicked it to view more (like in World Editor).

For 2)
your map size would definitely increase and so your load time might also increase but I think they won't cause lags or whatsoever since visible doodads don't cause lags(at least if they aren't animated)...

could you elaborate that more plz?

yes, I did the terrain. (with the ultimate terraining map)

thanks. so I will try to reduce the amount of them but not worry too much about it.

What about simply using regions to make areas visible / not visible depending on where you are located?

you could trigger it but that would be slow and complicated
including things as occlusion height would be even more complicated
it is possible but I think that it will lag with 50+ units

if there are less then like 300 units on the higher stage at once you could place ground vision blockers and move flying units with the higher units so they can see over them

thats the most promising idea so far. i will try to think that through.

Come to think of it it would be more complex than I thought. I'll do some digging.

You can however trigger your pathing using the SetTerrainPathable native. It would require some extra math.

yeah, i just wrote a function for that

pathing

function pathinginitialization takes nothing returns nothing
local real x = -2000
local real y
    loop
    exitwhen x >= 16000
    set y = -14500
        loop
        exitwhen y >= 3600
            if ( GetTerrainType(x, y) == 'Vrck' ) then
                call SetTerrainPathable(x,y,PATHING_TYPE_WALKABILITY,false)
            endif
            set y = y + 64                
        endloop
        call TriggerSyncReady()
        set x = x + 64
    endloop
endfunction

much better then spamming blockers, thanks.

The visibility is a little trickier though. You would have to trigger fog-modifiers.
