Spell which gives a buff while casting

[TaCoChris]

Hey guys.

I'm making a spell which should add a buff to the enemy target unit, while the casting unit is casting. (Cast time 3 sec.)
- And remove the buff if the unit stops.

(Similar to the hero "Sniper" in DotA)

Problems:
If i cast, and stop the spell instant, the buff wont get off. (the buff comes on to slow)

If the spell is casted, and i stop, the buff gets off. (should stay on, when the spell is casted)

If 2 units target the same enemy unit, and one of them stops, the buff goes off (should stay on if its still targed)

Secondly, if the target unit gets purged, the buff should get off, and the casting unit, should stop.

have you used hashtables before?

EDIT: heres what i came up with

• Map Initialization
  • Events
    • Map Initializations
  • Conditions
  • Actions
    • Hashtable - Create Hashtable

• Cast Start
  • Event
    • A unit BEGINS Channeling an ability
  • Conditions
    • Ability being cast is equal to (your ability) is true (boolean condition)
  • Actions
    • Hashtable - Save integer ((Hashtable - load integer (key target unit of ability cast) + 1) of 1 in last created hashtable) as (key target unit of ability cast) of 1 in last created hashtable
    • Hashtable - Save Unit (target unit of ability cast) as (key casting unit) of 2 in last created hashtable
    • Unit - Add Buff (your buff)

• Cast Stop
  • Events
    • A unit stops channeling an ability
  • Conditions
    • Ability being cast is equal to (your ability) is true
  • Actions
    • Hashtable - Save Integer (Hashtable - load integer (key target unit of ability cast) of 1 in last created hashtable) - 1 as (key target unit of ability cast) of 1 in last created hashtable
    • Hashtable - Save Unit (No Unit) as (key casting unit) of 2 in last created hashtable
    • If then else
      • If
        • (Hashtable - load integer (key casting unit) of 1 in last created hashtable) is equal to 0
      • Then
        • Unit - Remove Buff (your buff)
      • Else

the first trigger makes a hashtable
the second buffs the targets with the buff and sets an integer = itself +1 (saves the count for how many people are casting on the unit
and the 3rd removes the buff if and only if the unit has no units casting on it at that time

a bit, im actually trying to learn it.
Is that the key?

 

[GFreak45]

the key is the handle of the unit (basically gives you an integer value for the unit)

 

[TaCoChris]

i cant get a "Key Handle"
When i press at Handle, i cant choose anything?

- And its not possible to " Add buff "

 

[GFreak45]

im at work right now but when i get home ill look into it

 

[TaCoChris]

okay thank you very much, i will try some of your thing out myself.
- Else im waiting

Are you using NewGen? NewGen does not have the GUI Hashtable functions. You need to use the vanilla WE for hashtables in GUI.

 

[TaCoChris]

Yes im using NewGen, but im not very much into it. " jassnewgenpack5d "
