Traps every 10 seconds.

[CroMoX]

Hey Hivers, I have a question about making random traps

I was wondering how to make a trigger, where every 10 seconds, a water splash occurs (special effect), randomly in a region (The region is about 2/3 the size of a 32/32 map), and if a unit is hit by the water splash, it deals 100 damage to the unit.

Any help would be much appreciated.

• Untitled Trigger 001
  • Events
    • Time - Every 10.00 seconds of game time
  • Conditions
  • Actions
    • Set temp_pos = (Random point in (Playable map area))
    • Special Effect - Create a special effect at temp_pos using Abilities\Spells\Other\Volcano\VolcanoDeath.mdl
    • Special Effect - Destroy (Last created special effect)
    • Unit Group - Pick every unit in (Units within 512.00 of temp_pos) and do (Actions)
      • Loop - Actions
        • Unit - Kill (Picked unit)

You could also use this:

• Events
  • Time - Every 10.00 seconds of game time
• Conditions
• Actions
  • Unit - Create 1 Footman for Neutral Passive at (Random point in Region 012 <gen>) facing 270.00 degrees
  • Set TestVariable = (Last created unit)
  • Unit - Cause TestVariable to damage circular area after 0.00 seconds of radius 350.00 at (Position of TestVariable), dealing 99999.00 damage of attack type Chaos and damage type Normal
  • Wait 7.00 seconds
  • Unit - Kill TestVariable

Instead of footman create a dummy unit with the water model and replace it.
Region 12 is an example (obviously). Input the region you want in that place.
Radius 350 is also an example. Adjust the radius to you trigger needs.
TestVariable is a unit.
I hope I've helped.

@defskull, It's ok, I removed the leaks when I implemented his, so as long as I get the basic layout

Lol @Frotty, you forgot to remove the leak.

I also killed the unit. And used World Rect.
He wanted to know how, and not the perfect solution.
It was freehand

@CroMoX
Just use this to create temporary Unit Group

• Custom script: set bj_wantDestroyGroup = true
• ---HERE'S YOUR UNIT GROUP ACTION---

This way, you're saving 2 function call (which are setting Unit Group and destroying it), also saves you less 1 variable (no Unit Group variable).

Just remember to put that function call above Unit Group action to remove its leak without needing extra Unit Group variable.

Yeah ive seen people use that function call before, but never really wanted to use it cause im use to this way, but I shall use it to save me a variabe
