[Trigger] How to create a Unit Group in a line

[sephiroth1234]

Hello! Could someone tell me on how to create a Unit Group in a line? I need a GUI version, that includes all units in the line with an infinite distance or it can also be picked units even if it is on other end of the map? Thanks in advance and +rep for the replier(s)!!!

If the units are stationary, use a region, if they can move, then errhhh... try a region too?

No, I mean that to detect units like the first ability of the Tauren Chieftain in Melee maps, the Shockwave, I want to detect the units that is hit by the ability.

oooohhh, i misunderstood
Wouldn't this help :

• Event : Unit - A unit starts the effect of an ability
• Conditions : Ability beign cast equal to Shockwave
• Actions : Set (UnitVariable) = Target of ability beign cast.

and then do whatever you want

EDIT : READ HERE
No wait, i kinda lost it. The trigger is wrong. I don't know how to do it.
Ask Maker or Pharaoh_

Yes I tested it earlier but it detects nothing if the ability is cast on ground, if targeted on a unit, it only detects one unit, only the target unit. I am thinking of the unit offset function but I am still having problems.

Is there a "Unit in line of ability beign cast" and then set the range to (Shift + double click) infinite

Nope, none at all.

I just recall something like that. Maybe i'm wrong. I don't know. There is something complex, but i ain't JASS'ing, MUI, MPI, just normal simple GUI..

I wish Pharaoh or The Maker would reply to my post...

Yea. They are like the top of the top

In my CustomFilter system I have made a new Enumeration for units in a line.

function EnumUnitsInRangeOfLine takes group theGroup, real x1, real y1, real x2, real y2, real r returns nothing

This requires my CustomFilter system (vJass), however, you can easily call it with

call EnumUnitsInRangeOfLine(group, x1, y1, x2, y2, range)

To enumerate what you need.

Could I execute the line you've given as a Custom Script?, Because I am not good in JASS-ing.

 

[Anachron]

Of course you can.
However, you still need vJass for it. (And import my system)

I solved my problem now, thanks!!!

Additional GUI:

• Trigger
• Events
  • Unit - A unit starts the effect of an ability
• Conditions
  • (Ability being cast) Equal to X
• Actions
  • Set Points[1] = (Position of (Triggering unit))
  • Set Points[2] = (Target point of ability being cast)
  • For each (Integer A) from 1 to ((Distance between Points[1] and Points[2])/30), do (Actions)
    • Loop - Actions
      • Set Points[3] = (Points[1] offset by ((Real(IntegerA)*30) towards (Angle between Points[1] and Points[2])
      • Unit - Create 1 Footman for (Owner of (Triggering unit)) at Points[3] facing default building degrees
      • Unit Group - Add (Last created unit) to UnitGroup
      • Custom script: call RemoveLocation (udg_Points[3])
  • Custom script: call RemoveLocation (udg_Points[2])
  • Custom script: call RemoveLocation (udg_Points[1])

there is a better way to do it instead of picking units in 100 overlapping circles

however it is not that obvious
will take me a few hours to make it work
just wait and I'll edit it into this post later

Thanks Pharaoh! It also helped!
