[Trigger] Dummy Unit messing up

[tml616]

My ranger has an ability that slows the target 40% for 5 seconds and deals 12% of their max hp per second in damage if they are moving. So I can make each arrow spell look and act like a normal attack, without having the autocast of an orb ability, I have each arrow ability spawn a dummy unit with the same attack properties as the hero, order the dummy to attack, and then check the damage source when the target is damaged. Then the proper buff is applied based on which arrow dummy is the damage source.

So this spell I make a dummy spawn when the ability is cast, then I order it to attack the target. When the target is damaged by the dummy, a buff (Drunken Haze) is cast on them. Then the dummy is moved to the target's current location and checks every 0.2 seconds the distance between the target's position and the dummy's position to see if the target is moving. Problem is, sometimes the dummy unit just ends up at the middle of the map, does not cast the buff, and the spell fails. I don't know why.

You don't need to save Facing of unit to temp_real, since you only use it once.
I think the problem could be that the D.RNG-2 Venemous Arrow dummy (the one that attacks) dies before the arrow lands, so he is not detected as damage source in the second trigger. Try prolonging the expiration timer in the first trigger.

Yep I caught that and gave it a 6 second timer, but it still messes up sometimes. I enabled the model for the "source" dummy unit and it seems to instantly move to the center of the map on the first tick of damage.

I tried giving the spell infinite range, and it always fails if the target is out of the sight range of the caster, obviously need visibility for the dummy to cast the buff.

There are 2 ways it can mess up and it's annoying:

1. Buff is cast, but triggered damage does not occur (source moves to map center)

2. Buff is not cast but triggered damage still occurs

 

[M0RT]

Indeed, dummy needs visibility to cast the spell. However you can make the dummy as neutral hostile, so that he will always see (since the debuff doesn't deal the actual damage, it won't matter which player cast it). That should solve 2)

Map center is a default point returned as Position of non-existing unit.

I think a wrong Leak Removers can cause this. Wrong Leak Removers place can do a big effect. I tried this on my own maps. When i got an error with that, i just try different places.

I just guess that can cause.
