How to damage units once

BloodDrunk · Sep 15, 2014

How do I damage units once they come near the Ball using either buff or unit groups?

I've been trying with both, and it led me to failure.

Here's the trigger if you need it:

  - Time - Every 0.03 seconds of game time

Easiest way is 1 unit group and a unit in range trigger.
First check if triggering unit is in unit group.
If it isn't the damage and add it to the unit group.
If it is then it was damaged once before.

So I gotta make another trigger and add event from Init trigger?
If so, that'll pile up quite abit of events, won't it? Is that okay?

deathismyfriend · Sep 15, 2014

Use only one trigger. Using the ball as you said above use unit enter range of ball.
Then the rest as said above. If you keep creating more balls then yes you need to make a trigger for them.

You need to explain more on how the ball works.

Try Phoenix Fire with the damage over time set to 0.

Can you please explain how to use that spell?
First time hearing of it.

Vinz · Sep 15, 2014

It damages enemies the Phoenix comes near and applies a DoT. While the DoT ticks, the initial damage cannot be applied yet on the same unit. (Note; it does not show on the UI)

jonhysone · Sep 15, 2014

Just add the units you want to damage in Unit groups and damage them then directly remove them, I am very sure it works even with 0.03 loop trigger...

Vinz · Sep 15, 2014

What's the point of adding a group then?

He could just use bj_wantDestroyGroup and a group pick with an ITE. I think if Phoenix Fire does not work, he could separately index a caster-target relationship (instead of caster-group) so he could set a timer for all targets individually.

BloodDrunk · Sep 15, 2014

Well, it does not work with units...
It seemed like a perfect solution, but as always failed me!

deathismyfriend · Sep 15, 2014

If you are only trying to damage any unit once a unit group is the best with a unit in range event trigger.

Spent last 5 hrs trying to get this to work. Haha...
I guess I'll just rely on periodic damaging.

jonhysone · Sep 15, 2014

I am sure your problem with unit groups is about filtering ( Actually it means conditions )
Where you put 'And/All' or 'Or/Any'... That happens so much

deathismyfriend · Sep 15, 2014

This is how to do it very simply.

UnitInRangeSingleDamage
- Events
  - Unit - A unit comes within 256.00 of BallUnit
- Conditions
  - ((Triggering unit) is in ballSingleDamageUnitGroup) Equal to False
- Actions
  - Set tempUnit = (Triggering unit)
  - Unit - Cause BallUnit to damage tempUnit, dealing 100.00 damage of attack type Spells and damage type Normal
  - Unit Group - Add tempUnit to ballSingleDamageUnitGroup
  - Set tempUnit = No unit

The ball unit must be placed on the map in order for this to work. You can change the event and add it later when the ball gets created.

The unit group should never get removed and never be touched.

This will check if unit is in unit group then damage and add it to group if it is not in the unit group. That is how you make something only attack a unit once and that is all.

If you make multiple Balls and spawn them I can make a new way that is more efficient thanadding tons of triggers. The above works perfect and is efficient but only for one unit.

How did Phoenix Fire not work?

It seemed to perform perfectly for me on many occasions.

@OP

I sent the spell back to you through pm. You may want to post it on here so people can see how to damage a unit once with a unit group in a spell.

It's a wave spell?

Description: Sends forth a Ball Of Lightning that goes in a straight line, damaging any enemy unit it collides with.

It actually looks really nice

Vinz · Sep 16, 2014

This is something I've been trying to do a year ago, I failed a lot though (probably because I put enums in TempGroup, then removed units in group[] off TempGroup and finally added TempGroup to group[], which is rather weird and unnecessarily lengthy compared to this technique). I think you should submit it to the spell section, dimf. :thumbs_up:
