Make a region unpathable.

[DESTROYER123]

Hello once again everyone.
I got a problem.
How can I make a region totally unpathabe?
I have already done this:

• Environment - Set terrain pathing at (Center of Region 004 <gen>) of type Any to Off

But obviously it works only for the center of this region.
How can I replace the "Center of Region 004" so it can cover the hole Region 004??

Region characteristics:
Left: -640
Right: 288
Bottom: -4736
Top: -3744

Thank you.

Iterate over the region?

For every y in distances of 32 from minY to maxY
    For every x in distances of 32 from minX to maxX

Well, I think it would be easier just placing pathing blockers (air and ground) around the region, so you don't even need to cover the region of pathing blockers, a trigger is not needed in my opinion

 

[WaterKnight]

Coders ask themselves the reversed question. Why place stuff manually when you can do it via trigger? The region might change position/size, the mapmaker may place other doodads at this position that also requires pathing (which would get in conflict with blockers in the editor). However, wanted to respond because just covering the border can be troublesome when you have blink spells, triggered movement or units nudge each other like when being summoned for example.

What is this??
I want a triger fuction.

I also don't want to use pathing blockers because I don't want to use a lot of doodads (This triger is going to be used for a lot of regions.......)

native GetRectMinX takes rect whichRect returns real
native GetRectMaxX takes rect whichRect returns real
native GetRectMinY takes rect whichRect returns real
native GetRectMaxY takes rect whichRect returns real

Now itterate through X and Y with an offset of 32 untill every position within the rect has been covered with for example 32x32 pathing blockers. You can set them to variables and destroy the pathing blockers whenever you need afterwards.

A simple loop (itteration) that goes through all the positions within the region (rect) should work just fine.

Can u post a trigger. Because I don't know how to use this staff.....

I can't do that right now, I'm at work sorry :/

I made this:

function RegionUnpathable takes rect r returns nothing
    local real Xmin = GetRectMinX(r)
    local real Xmax = GetRectMaxX(r)
    local real Ymin = GetRectMinY(r)
    local real Ymax = GetRectMaxY(r)
    local real x = Xmin
    local real y = Ymin
    loop
        if ( x < Xmax ) and ( y == Ymin ) then
            call SetTerrainPathable( x, y, PATHING_TYPE_WALKABILITY, false )
            set x = x + 1
        elseif ( x == Xmax ) and ( y < Ymax ) then
            call SetTerrainPathable( x, y, PATHING_TYPE_WALKABILITY, false )
            set y = y + 1
        elseif ( x > Xmin ) and ( y == Ymax ) then
            call SetTerrainPathable( x, y, PATHING_TYPE_WALKABILITY, false )
            set x = x - 1
        elseif ( y > Ymin ) then
            call SetTerrainPathable( x, y, PATHING_TYPE_WALKABILITY, false )
            set y = y - 1
            exitwhen (y == Ymin )
        endif
    endloop
endfunction

It works, but im really tired so if someone see something wrong or it can be optimized, go ahead.

 

[Hashjie]

EDIT: This can't really be that much more optimized... nevermind what I said earlier, I have no right of speach here.

function RegionUnpathable takes rect r returns nothing
    local real Xmin = GetRectMinX(r)+16
    local real Xmax = GetRectMaxX(r)
    local real Ymin = GetRectMinY(r)+16
    local real Ymax = GetRectMaxY(r)
    local real x = Xmin
    local real y = Ymin

    loop
        exitwhen (y>yEnd)

        set x = Xmin

        loop
            exitwhen (x>xEnd)

            call SetTerrainPathable( x, y, PATHING_TYPE_WALKABILITY, false )

            set x=x+32
        endloop

        set y=y+32
    endloop
endfunction

A pathing cell is of the size 32*32. So you only need iterations worth of 32 x/y. Pathing cells originate in the left-lower corner each, so you should not include the cells of xMax/yMax, because this would add another row/column. This is why I made the offset of +16.

To be considered is that this should not be used on big regions as the 2d loop would easily accumulate enough operations to break the operation limit. Would require recursion or separation with thread instanciation then. Anyway, it is not performant anyway. Of course placing destructables with huge pathing maps is faster.

Thanks to much.
+rep for all of ya!

 

[Anvil]

I totally forgot the offset.
Thanks WaterKnight.

You can use a destructable as a pathing blocker and if you change the region size just change the destructable type with a different pathing type... As a suggestion. Of course I don't think that this way could be more efficient than blocking the maps pathing by code. It's an alternative from using pathing blockers as

 

[DESTROYER123]

Hmmmmmmm...That could work.
Btw can I place a giant pathing blocker??
I don't want to use a lot of pathing blockers cause it's going to fill my doodad space.

Also +rep for you.

 

[SA Dashie]

I think that this one is the biggest square pathing texture blocker.
PathTextures\12x12Default.tga
although there are others.
PathTextures\8x8Default.tga
PathTextures\6x6Default.tga
PathTextures\4x4Default.tga
PathTextures\2x2Default.tga
These are the basic strings.

This value is placed in the field of Pathing - Pathing Texture of the destructible that you want to edit. go through the others values if you want a different one or just ask me.
I would suggest using a pathing blocker as your base destructible.

Thank you very much my friend.
