[JASS] SaveUnitHandle bug

[Mechanical Man]

I have these lines:

    call SaveUnitHandle( udg_hashtable, GetHandleId(orderunit), udg_BatalionHash_TargetUnit, null )
    
    set orderunit = LoadUnitHandle( udg_hashtable, GetHandleId(orderunit), udg_BatalionHash_TargetUnit )
    call BJDebugMsg(GetUnitName(orderunit))

I get output with a unit name which was recently targeted, even though I nullified its handle in hashtable. I can store another unit, but I can't empty it for some reason. :S

Hashtables ignore nulls if I remember right. You either have to flush it or assign another proper value.

 

[Mechanical Man]

How can I flush them? It clears the whole hashtable?

Xonok is correct. Simply use:

native  RemoveSavedHandle                                       takes hashtable table, integer parentKey, integer childKey returns nothing

e.g.:

call RemoveSavedHandle( udg_hashtable, GetHandleId(orderunit), udg_BatalionHash_TargetUnit)

And that will clear up the reference in the hashtable.

Yes, just what I needed. My system works properly now after all these years. Thanks!

It should be the same story for gamecache btw.

Nobody uses gamecache nowadays.

Nobody uses gamecache nowadays.

There are some tasks the gamecache is still good for. Transfering data between maps, attaching data to strings, syncing data.

 

[Troll-Brain]

I'm wondering if StringHash + a string as a key of an hashtable to store data, would be faster or not than directly store the data in a gamecache with this string key.

You would have to handle collisions yourself.

You would have to handle collisions yourself.

Why, StringHash is not supposed to be safe enough for that ?
I mean, hell we don't know how it works behind.

Didn't remembered that, so a collision is possible in a real case ?
I'm not that good with maths.
