Using Dummy Units to Target Units in an AOE...

08-09-2006, 03:04 AM	#1
Ignitedstar	I'm making a spell that is sort of like Purge and Earthquake put together. What supposed to happen is that every unit in the 300 AOE of Earthquake get hit by Purge. I have to trigger that, but since Dummy Units are the ones who are going to use Purge, how do I make it so that each unit in the AOE get the Purge buff? If I'm not descriptive enough, then please say so. Thanks in advance.

Hello^^ Set Purge's Cooldown to 0, and try this:

Trigger:

Events

Unit - XXX Begins casting an ability

Conditions

(Ablitity Being Cast) Equal to Earthquake

Actions

Set tempPoint=(Point of Ability Being Cast)

Set tempPlayer=(Owner of (Triggering Unit))

Unit - Create 1 Dummy for tempPlayer at tempPoint facing 0.00 degrees

Set tempUG=(Units in 300.00 of tempPoint Matching ((Matching Unit) belongs to an enemy of tempPlayer))

Unit Group - Pick Every Unit in tempUG and do (Unit - Order (Last Created Unit) to Purge (Picked Unit))

Wait 1.00 seconds

Unit - Remove (Last Created Unit) from game

Custom Script: set udg_tempUG=null

Custom Script: set udg_tempPlayer=null

Custom Script: set udg_tempPoint=null

If there are errors point out plz! Hope there are NO LEAKS^^

DioD	Heh unit will not cast ANY spell...

Ignitedstar	So, even if I turn the Purge's cooldown to 0, one Dummy unit will purge all of the ones in the AOE? That's kinda strange. I'll try it out. Thanks.

You are leaking group and location

you should add

Trigger:

Custom script - call RemoveLocation(udg_tempPoint)

Custom script - call DestroyGroup(udg_tempUG)

blu_da_noob	That won't work, even with 0 cooldown there is a cast time for the spell. You will need to create a new dummy for each unit in the AoE and make it cast purge on that unit.

StockBreak	Yes, blu is right. There is the cast animation time and such (also if you put cast animation to 0 seconds, it will take time to cast etc...). Another thing: it is not wise to use "Last Created Unit" in a trigger after a wait (it should be replaced with a local/global variable).

DioD	Best way to use locals inside triggers like this.

Ignitedstar	I'm confused. Even if I create a number of Dummy Units equal to the number of units in the AOE, how will I know whether if they each cast Purge on each unit in the AOE or cast Purge on just one person in the AOE? I don't quite understand how to use local variables. Someone mind telling or directing me someplace?

Captain Griffen

Trigger:

Set TempGroup = Units within range you want to Purge

Unit Group - For each unit in Temp Group do actions

Loop

Set TempPoint = Position of (Picked Unit).

Unit - Create PURGER DUMMY at TempPoint.

Unit - Order (last created unit) to PURGE (Picked unit).

Unit - Add Generic expiration timer of 2 seconds to (last created unit).

Custom script: call RemoveLocation(udg_TempPoint).

Custom script: call DestroyGroup(udg_TempGroup).

The)TideHunter(	Yep, Griff is right. Although it was written himself, it is right!

Vexorian	Purge is instant cast. It is possible to make one dummy cast purge on multiple units in the same moment You only need a unit with cast backswing point and stuff like that set to 0. Just remember to move the unit to the position of the target and to reset cooldown and mana / have the spell cost 0 cooldown and mana.

blu_da_noob	Is that a special attribute of purge? I'm fairly sure it isn't like that for all spells.

Vexorian	Almost every spell is instant cast. So I see your "fairly sure" as "I did not try to change the fields of the dummy unit". In fact, this is the first reason I got to make the caster system.
