Get caster of Parasite

[Karzama]

Hi,

I have a unit summoned by Parasite but want to give it bonus stats based on the caster. However "Summoned Unit" gives the unit that died, rather than the caster.

If there any way of getting the caster?

 

[Uncle]

Did you try "Summoning Unit".

 

[Karzama]

Yes sorry that's what I meant. Summoned unit gets the summoned unit, while Summoning unit gets the unit that died rather than the caster

If the Event Responses don't work properly for Parasite you'll probably have to use some advanced methods.

A Unit Indexer or Hashtable could be used to track the Caster of Parasite by linking the Caster to the Target. This way you can get the Caster from the Target when the Target dies.

Alternatively, if there is only a single unit with this Parasite ability then you can easily track the Caster using a unit variable.

Since summoned units require a caster, have you tried "a unit starts the effect on an ability"?

Bribe's Damage engine has an Event called "LethalDamageEvent" that works, tested it and it catches the caster as the source of the damage from the DOT.

From there you could spawn a custom summon.

Thanks guys I'll have a play around with some things

But if the unit is killed by some other means while parasite is active, parasite will still trigger the unit spawn. Then you can't get the caster this way.

Damage Engine is way too overkill in my opinion. Unless they actually have the system in their map it's not worth it for a spell that can be solved with the most basic "custom value" method. Just need to link a Unit variable to a Unit.

Lethal damage event catches the killer and Damagetype filter via condition or specifc dummy casters could narrow it down.

If someone isn't using damage engine in their map or some equivalent it is already lacking.
Ah yeah, good point.

I don't think you understand the issue. The damage source is not necessarily the caster because the damage source could be something else entirely that happens to kill the unit and then spawn the parasite. Parasite doesn't require the caster to kill the target for a unit to spawn; it requires that the target dies while it has the buff. It could even be killed by a trigger or by a unit owned by a different player, etc..

The only solution I see is attaching information about the caster to the targeted unit (in a hashtable), so this info can be retrieved.

Hey, I've never used hashtables before, would you be able to explain how to do this?

@Karzama Did Devalut's links help you figure it out?

I ended up settling on just using Doom instead (it's a late game unit so the duration doesn't really matter), but do intend on learning more able hashtables as I think they'll come in handy at some point!
