can't understand why, but the dummy only casts the spell the first 2 times then stops. the spell's cooldown is 0.7 seconds and the dummy has its attack disabled and the locust ability so i don't think something can interferee with it.
am i missing something ?

Ok, here is how you are going to do it:

• Hash
  • Events
    • Map initialization
  • Conditions
  • Actions
    • Hashtable - Create a hashtable
    • Set Hash = (Last created hashtable)

• One
  • Events
    • Time - Elapsed game time is 173.00 seconds
  • Conditions
  • Actions
    • Custom script: local unit u
    • Custom script: set udg_Unit = CreateUnit (Player(12), 'hfoo', 0, 0 , 0)
    • Unit - Add Inferno to Unit
    • Unit Group - Add Unit to UnitGroup
    • Custom script: set u = udg_Unit
    • Custom script: call SaveInteger (udg_Hash, GetHandleId(u), StringHash("times"), 11)
    • Trigger - Turn on Two <gen>
    • Custom script: set u = null

• Two
  • Events
    • Time - Every 1.30 seconds of game time
  • Conditions
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (UnitGroup is empty) Equal to True
      • Then - Actions
        • Trigger - Turn off (This trigger)
      • Else - Actions
        • Unit Group - Pick every unit in UnitGroup and do (Actions)
          • Loop - Actions
            • Set Times = (Load (Key times) of (Key (Picked unit)) from Hash)
            • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
              • If - Conditions
                • Times Greater than 0
              • Then - Actions
                • Set Point1 = (Random point in (Playable map area))
                • Unit - Order (Picked unit) to Undead Dreadlord - Inferno Point1
                • Custom script: call RemoveLocation (udg_Point1)
                • Hashtable - Save (Times - 1) as (Key times) of (Key (Picked unit)) in Hash
              • Else - Actions
                • Unit Group - Remove (Picked unit) from UnitGroup

works excelent thx man ur my hero

im new to this stuff and wanted to ask what was wrong with the first trigger? i mean why didn't it work as i ordered it to do in the trigger, because in the same map i have another trigger like this one i showed and it works perfectly.

it takes kinda long to make a simple thing like this in this way i can't understand why it dosen't work with "waits".


anyway many thanks man, +rep it's all i can do in exchange

 

[Pharaoh_]

I believe (Last created unit) won't refer to the unit after so many waits. That might be the problem. You need to set the (Last created unit) in a variable, before you make the Order unit actions.
Finally, waits are inaccurate and inefficient.

 

[SpOnSoRu]

so... if another unit(footman for ex) is created trough a different trigger after the dummy was created, the "last created unit" in the dummy trigger will refer to the footman ?
an action in a trigger can interfeer with ones in other triggers?

God.... now i have to learn to use variables

 

[Pharaoh_]

That is a possible scenario, not a reason, so, yes, it can be.
You can redirect yourself here: https://www.hiveworkshop.com/forums/trigger-gui-editor-tutorials-279/variables-5896/

You also need to know what MUI is: Multi Unit Instanceability, meaning many units to perform same actions/spell casting/events without other units to interfere with their specific functionality, in case the latter ones cast anything after the first one.

(Last created unit) is supposed to work as its a local variable. Your dummy ran out of mana (my guess).
Hope that helps a bit.

 

[SpOnSoRu]

well.... there comes a time in a man's life when i has to learn GUI and MUI...

one last question... i don't feel like starting to learn those today cause im kinda' tierd, but until i learn... can u please show me how to clear a variable ?

for example if i set (last created unit) to the variable "unit" , afther i finish doing my job with it how do i clear it so i can use it again in the future ?

just the simple "clear" no other fancy stuff needed

(Last created unit) is supposed to work as its a local variable. Your dummy ran out of mana (my guess).
Hope that helps a bit.

nope... the spell uses 0 mana

 

[Pharaoh_]

In local variables (Jass, most likely) or indexing systems (e.g. Unit[Integer]), you have to null a unit as

local unit u = GetTriggerUnit()
set u = null

and

• Custom script: set udg_Unit[udg_Integer] = null

or

• Set Unit[Integer] = No unit

respectively.
It can also be done in GUI via Custom script:

• Custom script: local unit u = GetTriggerUnit()
• Custom script: set u = null

In global variables, you don't have to null it; it will replace the new unit with the unit stored in the previous event.

got it
many thanks for your help man. wish you the best
