Hashtable with Unit Group?

[JeffreyQ]

Can anyone point me out a good example of using unit group in hashtable?

I am trying to make a spell where the archer shoots 3 arrows at a point 1 after another. I move the arrow with triggers. And units in range of the arrow will get damage. But i only want them to get damage once since the move trigger is every 0.03seconds.

So i created a damagedGroup. Units in this group won't be damage anymore for that particular arrow.

Example:
If unit A stands in line. Caster shoots arrow, unit A will get hit 3 times because of the 3 arrows. Not more than that.

But i have problem using unit group in hashtable. I can't destroy it, if not my group will be empty. If i don't it will leak. ._. Anyone can shed some light?

Thanks in advance!

You can just destroy it before the arrow dies... I used it when my system was still using hashtables and no one pointed out that it leaks. And anyway the group will just stay there until you destroy it, saving it in a hashtable would just enable you to reference it again and again without causing errors in the spell being MUI, it wont create a new one so as long as you use the group its not a leak but be sure to destroy it when its not needed anymore.

i still can't get my group save in hashtable to work properly. What am i doing wrong?

I am trying to make a pierce arrow. So when unit is in range on the arrow, they will get damage once by adding them to the damagedGroup after being damage.

But the problem is when i spam the skill, for example i shoots 5 arrows within 3 seconds to a far away point. Units that are in the line will only get damaged once by the 1st arrow. And the other arrow won't do damage. Because they are still in the damagedGroup for some reason.

Heres my example code:

Last Created unit is the Arrow. I create it when i run the trigger.

• Hashtable - Save Handle OfArrow_DamagedGroup as (Key dmggroup) of (Key (Last created unit)) in myArrowTable

Every 0.03 seconds, i pick every unit in the ArrowGroup and load the damagedGroup

• Set Arrow_DamagedGroup = (Load (Key dmggroup) of (Key (Picked unit)) in myArrowTable)

I set a unitGroup to get units around the arrow and do damage and pick every unit to do damage, after damage, i add them to Arrow_DamagedGroup

• Unit Group - Add (Picked unit) to Arrow_DamagedGroup

Finally i update my group Hashtable.

• Hashtable - Save Handle OfArrow_DamagedGroup as (Key dmggroup) of (Key (Picked unit)) in myArrowTable

But somehow all the above don't work. I know it has something to do with the damagedGroup. How do i make it MUI for each Arrow? I saved it in hash but it didn't work like other handles (Real, Unit, String, Integer)

Note: i didn't destroy the group in any part of the trigger.

Could you post the system in a map? It's easier to fix that way.

I have fixed it. I added a custom script before saving it in hashtable. "set udg_Arrow_DamagedGroup = CreateGroup()"

But now, i have no idea if this leaks. Because if i try to destroy it in the creation of arrow or movement, it will screw up.

You could do it like this:

• Unit Group - Add (Picked unit) to (Load (Key dmggroup) of (Key (Picked unit)) in myArrowTable)

I don't think you should save the handle again.

Then destroy the group when the arrow dies.

What is the difference between doing:

• Set Arrow_DamagedGroup = (Load (Key dmggroup) of (Key (Picked unit)) in myArrowTable)
• Unit Group - Add (Picked unit) to Arrow_DamagedGroup

and

• Unit Group - Add (Picked unit) to (Load (Key dmggroup) of (Key (Picked unit)) in myArrowTable)

? Just want to know. Because if its the same, it didn't work.

Maybe it doesn't support loading and saving at the same time?

What is the difference between doing:

• Set Arrow_DamagedGroup = (Load (Key dmggroup) of (Key (Picked unit)) in myArrowTable)
• Unit Group - Add (Picked unit) to Arrow_DamagedGroup

• Unit Group - Add (Picked unit) to (Load (Key dmggroup) of (Key (Picked unit)) in myArrowTable)

? Just want to know. Because if its the same, it didn't work.

The trigger I posted is erroneus, since those picked units are referencing to the same unit, they should not.

Could you post the whole triggers, it's easier to see what's going on in there.

I uploaded my system. I have the code written there.
