Need Help w/ Hashtables

[sentrywiz]

Hi guys

I'm trying (been trying) to make a damage over time spell with hashtables.
And I'm stuck.

1st - I cannot configure like I said, a dot spell that will damage a unit 5 times. I have the whole trigger made like:

a) When casting the ability, configures the damage and saves it in a hashtable. It also calculates the time needed, in my case its an real variable set to 5. After that the target of ability being cast is added to DamageOverTime unit group

b) A periodic trigger that runs every 1 second is supposed to damage every unit in the unit group above mentioned. This is where I have problems


problem1) The casting unit cannot damage the target. Because its in a periodic trigger, I cannot use casting unit cuz which casting unit? I tried to save the casting unit in a unit variable under casting unit, but that didn't work when I tried to "Damage Target - ? Unit damages Picked Unit dealing X damage,"

problem2) I don't know how to use key handles. I tried to save in hashtable anything with 0 and key(casting unit) since it said in wyrmlord's tutorial that each unit has an ID handle. However it doesn't work for me. Or better yet, I don't work with it ..


Need help!
Thanks

Also, if you have ease with hashtables and has time - make a simple trigger to show me how pros do it

Anyway, an answer or a trigger would be great

You need a basic advance of triggering in GUI before going on to Hashtables
Basically, hashtable usage is you save the data, and load them later, appropriately for each unique unit, basically, this will make the trigger MUI
Basic Learning:
Hashtable Spellpack - You can learn many things in this spellpack, it uses hashtable and it is approved resource
Hashtable Tutorials- I learned hashtable from here, you should be able to understand the explanation very well, just follow step-by-step and you got it !

          • Then - Actions
            • Unit Group - Remove (Picked unit) from DOTGroup
          • Else - Actions

These would be triggers for a simple DOT spell.

Do you forgot to:

• Unit Group - Add (Target unit of ability being cast) to DOTGroup

Aw right,thanks defskull.

 

[sentrywiz]

Thanks guys.

I also noticed, you don't clear child hashtables. Is it a good thing to clear or doesn't matter?

+rep both.

 

[defskull]

Must clear
Child hashtable action

• Hashtable - Clear all child hashtables of child (Key (Picked unit)) in DOTGroup

 

[Garfield1337]

Omg i'm so forgetful ._.
Just add that function after

• Unit Group - Remove (Picked unit) from DOTGroup

in loop trigger.

 

[sentrywiz]

Thanks for the explanation guys, the trigger works like a charm. However, floating text doesn't like hashtables. I can't make it so floating text takes the value from the hashtable and uses it to display the amount of damage dealt.

• Floating Text - Create floating text that reads (Load 2 of (Key (Picked unit)) from Hashy) above (Picked unit) with Z offset 0.00, using font size 9.00, color (100.00%, 0.00%, 0.00%), and 0.00% transparency

Wheres the error in this?

 

[Maker]

The thing you load is a real, floating texts are supposed to display strings.

Use convert string to real.

I thank you for that, +rep

Well, I need to give rep before you get more rep from me, but for now thanks!
