[JASS] Nullifying A Value In Hashtables

[Starquizer]

This:

function ClearHashtablePointDataTest takes nothing returns nothing
    local unit u = gg_unit_Emoo_0005
    call SaveUnitHandle(css_data , 1 , 1 , u )
    call pop(ut2s(u))
    call SaveUnitHandle(css_data , 1 , 1 , null )
    call pop(ut2s(LoadUnitHandle(css_data , 1 , 1)))
endfunction

Is displaying in the game:

Can I null a certain value in the hashtable without using flush functions ?

No you can't, you just can't save an invalid handle on an hashtable (null or not)
Note that's it's probably the same with gamecache.

Damn it, now my system has collapsed entirely.

I will have to think of something else.

Thanks Troll-Brain.

If that helps you still can make a custom function such as :

SaveUnitHandleBJ

if ... == null then
Flush ...
endif

I am making a CSS (Combat State System) so I wanted to save a null value because I do loop search for the first null value (parent key is fixed and child key is a loop index) then I save a unit that is in combat to this location and when it leaves combat I simply fill that location with null but without being able to null this location the system fails, so that lead me to think of saving a dummy unit that will flag this location as null.

Anyway, thanks again for the info

<<< EDIT >>>

Actually, I found a way to null the value (PARTIALLY). Do you remember an old thread I posted about saving handles in a hashtable, where I found that you can't save more than one handle in the table. So I used that and saved a dummy item I created with the same parent and child keys so when I tried to get the value with the same keys but unit handles it returned null because I am already saving an item handle.
