[JASS] Path checking

[Kazeon]

I wonder why this function failed to check terrain's flyability,

if IsTerrainPathable(x, y, PATHING_TYPE_FLYABILITY) then

Is there a way to check whether a flying unit can fly through a certain location (x, y) or not?

Thanks for any help.

Afair IsTerrainPathable always returned the opposite of what you'd expect.

This specific function returns the opposite of what it should. Check the BJ version to see.

I know. But it just never returns true. It means it never detect unflyable terrain. Whereas I stand above some path blocker (Air). Except if that function indeed can not detect pathing blocker.

You could move a dummy flying unit to that location and see if its X/Y correspond with the point's X/Y. Assuming of course that the move unit function will move the unit to the closest legal location.

So, that function indeed can't work? Okay then, got it. Thanks..

It's strange that nobody has ever get this problem before. At first, I thought I did something wrong.

Looks like the GUI function exists, this is the JASS it spits out:

if ( not ( IsTerrainPathableBJ(udg_loc1, PATHING_TYPE_FLYABILITY) == true ) ) then
        return false
    endif

It can't. That's why we have so many resources that handle pathing checks.
