Is there a way to detect

[Doom-Angel]

Is there a way to detect if a unit cannot be created\reach on\to a certain location?
example: a wall in the way,water,some unwalkable terrain and etc'.
thanks in advance

If then else in IsTerrainType...
Or something

 

[Trollvottel]

or IsTerrainPathable

 

[Doom-Angel]

what about checking if a wall\unit\destructible\doodad is ditrupting?

 

[PurgeandFire]

I don't think so.

You can't check if it is water either afaik.

You can't check if it is water either afaik.

Yes, but you can check the surface under it...


I have this crazy idea, ludicrous.

Hear me out...quietly.


When a unit is created onto a position, which is blocked, it gets moved to the nearest unblocked position...

function IsPositionPathable takes real x, real y returns boolean
    local unit test = CreateUnit(Player(15), 'hfoo', x, y, 0)
    if (GetUnitX(test) == x) and (GetUnitY(test) == y) then
        call RemoveUnit(test)
        set test = null       
        return true
    endif
    call RemoveUnit(test)
    set test = null
    return false
endfunction

It's crazy enough to work!

Andrew that's actually a good way thanks again i shall try it out and i will see the results of it
+Rep for all the helpers

And if you find it doing what you need, then here's an optimised version.

function IsPositionPathable takes real x, real y returns boolean
    local boolean flag
    set bj_ghoul[77] = CreateUnit(Player(15), 'hfoo', x, y, 0)
    set flag = (GetUnitX(bj_ghoul[77]) == x) and (GetUnitY(bj_ghoul[77]) == y)
    call RemoveUnit(bj_ghoul[77])
    return flag
endfunction

k i tried it now i even added a few more thing such as unit with locust and such:

function IsPositionPathable takes real x, real y returns boolean
    local boolean flag
    local unit u
    set u = CreateUnit(Player(15), 'n000', x, y, 0)
    call SetUnitX(u,x)
    call SetUnitY(u,y)
    set flag = (GetUnitX(u) == x) and (GetUnitY(u) == y)
    call RemoveUnit(u)
    return flag
endfunction

it works about the parts it shouldn't be working but at the parts where it should work it's not always working for some reason....
got any clue what might be wrong?

 

[Andrewgosu]

The fact you are using 'Locust', "SetUnitX" and "SetUnitX" functions?

"SetUnitX" and "SetUnitX" ignore pathing. You do not want that.

Just use the function I posted, unaltered.

 

[Doom-Angel]

without the SetUnitX it works even worse i tried it before - that's why i added it
also i could try set location functions

It's crazy enough to work!

I did not add that it will work as expected. Oh well.

[Doom-Angel]

well at this link you just gave me is more than enough

 

[Doom-Angel]

sorry for the double post but something is wrong with the system:
it works only on some of the things - for example: on gates and barrels it worked but the tree didn't work for this check....
anyway to solve this one?
