How to save null in hashtables?

[Tawnttoo]

I'm having trouble erasing item handles. I presume there's a JASS word for saving nothing as an item handle. I tried with GUI saving handle of No Item, but it doesn't work. All I'm trying to do is clear an "inventory slot" in my system. Triggers and/or map will be posted when asked.

Simply flush the child hashtable.

If I do that, it will erase every item handle connected to the child. I need to erase a single handle.

I don't think this can be done in GUI, but if you're willing to use some JASS, then do the following

/* Check if the hashtable contains the desired handle. */
if HaveSavedHandle(table, parentKey, childKey) then
    /* Remove the handle from the hashtable. */
    call RemoveSavedHandle(table, parentKey, childKey) 
endif

Nope, it can't. Does using JASS require me to use some other programs besides WE to save/play the map? Or is it so that GUI is converted into JASS when the map is being tested (as I have understood)?


Thanks for your effort, but I already found a way to work around it.

Thanks again.

GUI is JASS. JASS itself requires no other programs at all.

Anyhow, just use the removing method.

It'd be more efficient than any workaround.
