How to check the existence of destructables...

UnMi	Hmm, how would I be able to see wether there are destructables in an area/rect/whatever or not!?

Tide-Arc Ephemera	I am not purely sure but I think this actually a condition. If I'm not sure, I'm sorry. If this isn't it, try looking for "count" Integer - Destructibles in region is equal to or greater that 0 OR make a trigger that picks all doodads in a region, then add 1 to that varible, then make a comparison that will check that variable. There could also be a boolean but I'm not sure...

Wow, I just found the BJ function RandomDestructableInRectSimpleBJ, which like, works ...o_O.
It has the same concept like you said, but while I was bothering how to save and receive the integer Count, BJ just used some random bj_ variables? =.=;
It's even multi-instanceable, not bad for a BJ.
Still, I have no idea about the true mechanics about it...(what are bj_ variables?)

JASS:

function RandomDestructableInRectBJEnum takes nothing returns nothing
    set bj_destRandomConsidered = bj_destRandomConsidered + 1
    if (GetRandomInt(1,bj_destRandomConsidered) == 1) then
        set bj_destRandomCurrentPick = GetEnumDestructable()
    endif
endfunction

function RandomDestructableInRectBJ takes rect r, boolexpr filter returns destructable
    set bj_destRandomConsidered = 0
    set bj_destRandomCurrentPick = null
    call EnumDestructablesInRect(r, filter, function RandomDestructableInRectBJEnum)
    call DestroyBoolExpr(filter)
    return bj_destRandomCurrentPick
endfunction
