AoE Invisibilty

[Minoros1]

Hello,

I want to make a spell that when used makes all friendly units invisible for 5 seconds.

Its an AoE ability you use it and every friendly unit that is in the range of that ability is invisible.

Hope you can help me.

Thanks!

Check for alive friendly non-structure units in the range of the caster, create temporary dummy, add invisibility-ability to it, make it cast the invisibility to the picked unit.

When i do this only 1 unit gets the invisibilty. Did i do something wrong?

Everything worked. I need this for an rpg map and i have triggers that have a chance to create gold when units die. Now if i use the ability it drops 1 gold piece for every unit that get the invisibilty. This is really weird anyway to firx this. Thanks for the explanation tho!

well, since the dummies you use to make the units invisible are also units and they die after 3 seconds (see expiration timer in the trigger) they will also trigger your gold-drop-trigger. what you just have to do is to check in your gold-drop-trigger if the dying unit is a dummy or not, if it is you just end the trigger, or set the chance to 0%.

But it drops Gold for every unit that gets invisible. I tried to make 2 invisible 2 Gold Coins. 4 invisible 4 Gold coins.

By the way, I just gave you an inefficient trigger, I didn't know the (Last created unit) runs through function call,

change the enum to this:

• Unit Group - Pick every unit in (Units within <Your range> of Point_CasterPosition matching ((((Matching unit) is alive) Equal to True) and ((((Matching unit) belongs to an ally of Player_Owner) Equal to True) and (((Matching unit) is A structure) Equal to False)))) and do (Actions)
  • Loop - Actions
    • Unit - Create 1 <Your dummy> for Player_Owner at Point_CasterPosition facing Default building facing degrees
    • Set Unit_Dummy = (Last created unit)
    • Unit - Add Invisibility to Unit_Dummy
    • Unit - Order Unit_Dummy to Human Sorceress - Invisibility (Picked unit)
    • Unit - Add a 3.00 second Generic expiration timer to Unit_Dummy

i have triggers that have a chance to create gold when units die. Now if i use the ability it drops 1 gold piece for every unit that get the invisibilty.

Just like jopi said, run the gold giving units through a filter where you filter out units of type <Your dummy>.

Edit: Can you post the gold bounty triggers here?

Add in the trigger's conditions block:
(Unit-type of (Triggering unit)) is (<Your dummy>) equal to false

(Position of (Dying Unit)) leaks. Store it in a variable and use "call RemoveLocation(udg_<var>)". Also use Triggering Unit over Dying Unit.
