Line Damage.

[DESTROYER123]

Hey people!
I had been making (since a lot of time) a blink spell which deals 100 damage to all units betwenn the 2 points.
But I can't make it.
Can anyone post a simple trigger fuction (explaining the variables please).


Thanks.

point offset then use a group loop to get all units in range of point and deal damage to them

Could you be more specific?

Here's the trigger:

    • Unit Group - Pick every unit in (Units in (Region(Point015, Point016))) and do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • ((Picked unit) belongs to an enemy of (Owner of (Triggering unit))) Equal to True
          • Then - Actions

There's probably a more efficient way to do this but I don't remember anything about geometric equations. Basically it draws a line and determines if any targets within range of the ability are within 100 distance of the line.

 

[Nichilus]

I think it may be better efficiency-wise to pick all units within range of center the line and check if their X and Y coordinates are close to any X and Y coordinate on the line. (As I understand it, "pick every unit" action takes a lot of power)

edit: or you could simply calculate the distance between point and a line and if that distance is less than or equal to *your AoE range*, you damage unit.

There is another active topic about damaging units in a line (or in a rect which is basically the same).
