Hash Tables?

Anyone got an example of use of hashtables ... I've come across a few things like count down or specific multiboard where having the identity of the object via the handle would be nice.

I'm just wondering if there's a tutorial or example out there. I searched the following sections...(with word hashtable)

http://war3.incgamers.com/forums/forumdisplay.php?f=40 's

"General"

"Basic"

"Advanced"

Also, is the 0 of 0 the location inside the hash?

I'm really just looking for how to grab timer/board handles. If you guys have better suggestions I'm interested too. I looked at the dota example he's got some pick every player and player grouping going on, which really adds too much to my editor currently.|||So, I'm a little daft & found out the timer window variable is just a pointer, not a storage location for the actual data...too simple.

Still looking for information on the hashtables - what do you guys use them for & why does google show that only 2 people on the internet remotely know what to do with them (and willing to talk about it)?|||I am currently working with hastables, and tell you they are a very powerful tool for indexing as you can think of the map.

I designed such a spell that is running in multiple instances, like the knockback but in this case the unit is moved in the direction spellcasting front cutting everything in its path. for this use a timer that is stored in the hash table. the event which serves to collect the id of the timer is GetExpiredTimer () and the script works like this: (note that hashtables do not use locally, defined as global variables is better, since its are re-usable)

first create the global variable hashtable called "cache" and later make the hastable in your initialize trigger

this in gui mode

hashtable-create hashtable

set cache = lastcreatedhashtable

later define the script


Code:

function Silverslash_move takes nothing returns nothing
    local timer ti = GetExpiredTimer()
    local unit u = LoadUnitHandleBJ(StringHashBJ("caster"),GetHandleIdBJ(ti), udg_cache)
    local real inc = LoadRealBJ(StringHashBJ("inc"),GetHandleIdBJ(ti), udg_cache)
    local real ang = LoadRealBJ(StringHashBJ("angle"),GetHandleIdBJ(ti), udg_cache)
    local location p = GetUnitLoc(u)
    local location p1 = PolarProjectionBJ(p, inc, ang)

    set inc = ( inc - 1 )
    set p = GetUnitLoc(u)
    call SetUnitPathing( u, false )
    call SetUnitPositionLoc( u, p1 )
    call RemoveLocation(p)
    call RemoveLocation(p1)
call SaveRealBJ(inc, StringHashBJ("inc"), GetHandleIdBJ(ti), udg_cache )

    set u = null
 endfunction

function Trig_silverslashX_Conditions takes nothing returns boolean
    if ( not ( GetSpellAbilityId() == 'A06H' ) ) then
        return false
    endif
    return true
endfunction

function Trig_silverslashX_Actions takes nothing returns nothing
    local unit u = GetSpellAbilityUnit()
    local real inc = 30.00
    local real ang = GetUnitFacing(u)
    local timer te = CreateTimer()
    local location p = GetUnitLoc(u)
   

    call SaveUnitHandleBJ(u, StringHashBJ("caster"), GetHandleIdBJ(te), udg_cache )
    call SaveRealBJ(inc, StringHashBJ("inc"), GetHandleIdBJ(te), udg_cache )
    call SaveRealBJ(ang, StringHashBJ("angle"), GetHandleIdBJ(te), udg_cache )
    call SaveLocationHandleBJ(p, StringHashBJ("p"), GetHandleIdBJ(te), udg_cache )


    call TriggerSleepAction( 0.04 )
    call UnitAddAbilityBJ( 'A06J', u )
    call SetUnitAnimation( u, "Attack" )

    call TimerStart(te, 0.02, true, function Silverslash_move)

    call PolledWait(0.4)

    call UnitRemoveAbilityBJ( 'A06J', u )
    call SetUnitPathing( u, true )

    call FlushChildHashtableBJ(GetHandleIdBJ(te), udg_cache)
    call DestroyTimer(te)
    set u = null
    set inc = 0
    set ang = 0
    call RemoveLocation(p)
    

endfunction

//===========================================================================
function InitTrig_silverslashX takes nothing returns nothing
    set gg_trg_silverslashX = CreateTrigger( )
    call TriggerRegisterAnyUnitEventBJ( gg_trg_silverslashX, EVENT_PLAYER_UNIT_SPELL_CAST )
    call TriggerAddCondition( gg_trg_silverslashX, Condition( function Trig_silverslashX_Conditions ) )
    call TriggerAddAction( gg_trg_silverslashX, function Trig_silverslashX_Actions )
endfunction

voila, this work nice (note, the spell desing dont consider terrain patchability and the move orders are very basic, only its a basic example of stored timers in hashtables.)

the timer stored is the handle of the local timer called "te" in the actions function, this timer looping until the polledwait finish, later in each finish of the "te" success the expired timer event, here you can get the id of the timer with the native function GetExpiredTimer()

sorry for my english, i used a google translator.
