Clearing Hashtables

[Sil3nt]

I've read through a few threads but I'm still not very sure about whether or not hashtables need to be cleared, or when. Take these 2 triggers of mine for example:

• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • (Percentage life of (Picked unit)) Less than or equal to 40.00
  • Then - Actions
    • Special Effect - Create a special effect attached to the weapon, left of (Picked unit) using Abilities\Spells\Orc\TrollBerserk\HeadhunterWEAPONSLeft.mdl
    • Hashtable - Save Handle Of(Last created special effect) as (Key effect1) of (Key (Picked unit)) in hashTable_berserker_blood
    • Special Effect - Create a special effect attached to the weapon, right of (Picked unit) using Abilities\Spells\Orc\TrollBerserk\HeadhunterWEAPONSLeft.mdl
    • Hashtable - Save Handle Of(Last created special effect) as (Key effect2) of (Key (Picked unit)) in hashTable_berserker_blood
  • Else - Actions
    • Special Effect - Destroy (Load (Key effect1) of (Key (Picked unit)) in hashTable_berserker_blood)
    • Special Effect - Destroy (Load (Key effect2) of (Key (Picked unit)) in hashTable_berserker_blood)

Should I be clearing the special effects from the hashtable after destroying it? How would I do it?

• Hashtable - Clear all child hashtables of child (Key (Picked unit)) in hashTable_berserker_blood
  • <div class="bbCodeBlock bbCodeBlock--screenLimited bbCodeBlock--code"><div class="bbCodeBlock-title">Trigger:</div><div class="wc3trigger"><ul class="wc3" id="wc3_2">
  • <li class="lastopen"><span class="default">Hashtable - Clear all child hashtables of child (Key effect1) in hashTable_berserker_blood</span>
  • <ul>
  • <li class="lasttree"><span class="default">Hashtable - Clear all child hashtables of child (Key effect2) in hashTable_berserker_blood</span></li>
  • </ul>
  • </li>
  • </ul>
  • </div></div>
  • I assume I would use the first one only, right?
  • Another trigger
  • <div class="bbCodeBlock bbCodeBlock--screenLimited bbCodeBlock--code"><div class="bbCodeBlock-title">Trigger:</div><div class="wc3trigger"><ul class="wc3" id="wc3_3">

  • <li class="lasttree"><span class="default">(Triggering unit) Equal to (Load (Key target) of (Key (Attacking unit)) in hashTable_fervor)</span></li>

  • <li class="tree"><span class="default">Hashtable - Save Handle Of(Triggering unit) as (Key target) of (Key (Attacking unit)) in hashTable_fervor</span></li>
  • <li class="lasttree"><span class="unit">Unit - Set level of Fervor (Attack Speed Bonus 20%) for (Attacking unit) to 1</span></li>
  • </ul>
  • </li>
  • </ul>

  • </ul>
  • </li>
  • </ul>
  • </li>
  • </ul>
  • </div></div>
  • Should I be clearing the hashtable before overwriting it with another unit?
  • What if it were a location, unit group, or something that would normally need a custom script in GUI to clean? Would I need a &#039;temp_loc&#039; or anything like that at all if I&#039;m using hashtables?
  • Any help is appreciated!
