GUI Passive ability that creates unit from the corps

[Primstan]

The idea of a spell is kind of based on Black Arrow ability.

With every attack hero puts a buff on enemy target (that lasts about 20 seconds, buff reapplies with each basic attack), if during this time target is killed then there is a chance (15/30/45) to create a certain unit from the corps (like Black Arrow).

I checked many posts with similar to Black Arrow skills and didn't find what I was looking for. I would appreciate some ideas and thoughts regarding this.

 

[Pyrogasm]

Do you only want it to spawn if a unit is killed by an actual attack, or if killed by anything while the buff is active?

There is already a passive ability for this, shadow orb. "Item Attack Black Arrow Bonus" and "Item Black Arrow". The chance has to be triggered though, you could do something like this

Killed by anything, as long as debuff active.

Theoretically, I could create shadow orb ability for my hero. Then change the chance to affect a unit (it has 100% by default), then I would change summoned unit type to the type I need. Let's say I would set a chance to 15% at level 1, wouldn't it mean, that with every hero basic attack the chance would reapply, resulting in creating that skeleton for example.

And with Your trigger that chance wouldn't be reapplied with every hit, but with the death of unit? (Because that's what I need) I am just trying to understand Your trigger. Sorry, I am not very experienced in triggering.

Yes exactly, I haven't tried it but it should work. All it does is that, depending on what level the summoned unit is, it has a chance(15,30,45) to not kill and hide the unit. Otherwise it will kill and hide the unit, making it look like nothing happened.

So you will have to use a different unit-type on each level (like with regular Black Arrow)

This indexing you're using is it more effective than using a unit group? Or is it just a preference you have?

 

[Devalut]

@Sk0gsHu[GG]arN
Definitely a preference, as for effectiveness I'm not sure, though @Pyrogasm could certainly enlighten us.

 

[Pyrogasm]

Edit: I didn't actually read @Sk0gsHu[GG]arN 's response until I posted and I think I just repeated what they said the other option is. This way is simpler to understand if you don't 'get' indexing but as far as "better"...? Either is acceptable, though this way avoids an explicit requirement of a unit indexer.


Instead of indexing by caster you could keep a single unit group for each player and store targets that that player has put the buff on in that group. Then you check what group the unit is in (when it dies) to see who to give the newly spawned unit to. When the buff is applied remove it from all other groups (since only the most recent application should count), and if the unit takes fatal damage while it doesn't have the buff remove it from the group.

It's a lot easier with unit indexer but you can also use a hashtable

 

[Primstan]

Trigger you came up with is mind blowing... Would be great if you could elaborate a little bit (I mean explain the trigger, for example "Damage Event becomes equal to 1.00", what's that?) and guide me through the steps. So far I created Shadow Orb ability in OE, obviously changed the chances and then changed the Summoned unit (it is the same unit for all 3 levels of ability (Footman)). I didn't start triggering the ability yet, because I was distracted by another ability of Mass Heal.

I am just confused with variables a little. I am sorry for my knowledge, learning everything is always most complicated part of it.
