Chain lightning release on attack?

[ZEEP]

I havent found a topic or something that containts the idea to create a chain lightning on attack like Mjonnir in DotA.Does anybody have an idea how is this spell made in JASS?
Im sorry once again if i didnt look but I didnt find any thread about this in the site.

another Dota...not all people here plays dota so better put the description...

I am not sure if this is what you'r looking for but:

• Chain Tower
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • (Unit-type of (Attacking unit)) Equal to (==) Chain Lightning Tower
  • Actions
    • Unit - Order (Attacking unit) to Orc Far Seer - Chain Lightning (Attacked unit)

Its an Orb Effect, in other words its not even scripted.

Base an ability of Orb of Lightning and ste the effect ability to Chain Lightning or whatever.

Voila.

 

[defskull]

You can also use Orb of Slow as base orb

 

[Wazzz]

The problem with Orb effects is you have to actually be attacking or attack moving for the effects to come into play. Should your unit be stationary, the effect will not work. Trust me, it's guranteed.

Additionally, using the 'unit is attacked' event is dodgy, as it will come into effect before you actually attack. In this case it shouldn't matter, though.

What are you talking about man... ?
It's not even scripted (doesn't touch Trigger Editor), so there's no need the use of "Unit Is Attacked" and such lol

You need to order your unit for the orb effect to occur,that's what he was talking about i think.

 

[Wazzz]

^
Yea, I've had a lot of bad experiences with Orb effects

 

[defskull]

We need to order such as "Attack" command ?
I always use "Attack Move" command it works very well...
Well, I think it is bad when you put it at towers, right ?

 

[Wazzz]

Yes, Attack Move works as well. What I'm saying is if you have your unit stationary, an enemy unit comes within proximity and thus your unit starts attacking it without being ordered in any way, the effect won't work. Which is not too good imo.

 

[defskull]

And IF you played DotA, you would know a hero named Anub'seran
He can attack double (orb effect)
If he's not ordered to attack, the effect won't appear which is, SUCK hard

Correct. To check if unit is actually attacked or not (projectile launched, hit the target etc..)
1-) I used to create an orb of corruption based ability, give it to the attacker and,
2-) Disable it with triggers instantly so it takes no space in UI.
3-) Then I remove the effect (armor reduce) from it.
4-) After that, I create a new buff named "Physical Attack" (editor name only) but I remove icons and special effects from it so it wont show up in attacked unit's status bar,
5-) Then I create a trigger that checks if unit has buff or not every 0.05 seonds.
6-) If attacked unit has the buff, I create a dummy to cast the lightining.
If author of the topic is willing to prevent that problem from occuring, he can use this =)

 

[kleinerhauck]

instead of checking every 0.05secs you should use 'Unit takes damage' event.
You have to add this event to the trigger whenever a units enters the map though via Trigger - Add new event: Triggering unit takes damage.

 

[defskull]

OR, just use Weep's GUI Damage Detection and trigger yourself the ability of Chain Lightning
I made it that the tower will release a 20% chance of Chain Lightning at a time

[Wazzz]

Hell, I'm going to have to check this out, defskull, sounds awesome ^^
That way I'll be able to have some proper effects in play, thx

 

[Dr Super Good]

Heroes generally will never stand around and attack in defense unless in a RTS map. AoS maps require constant movement and target specification.

Did I helped you for your long-ago trouble ?
Cheers !

^ Has a flaw.
Try to remove towers,put a Blood Mage on map,change the condition to

• (Unit-type of GDD_DamageSource) Equal to Blood Mage

,set chance to

• (Random integer number between 1 and 100) Less than or equal to 100

and cast Flame Strike (or Banish) with Blood Mage among peasants.

ujelly?

 

[defskull]

Too lazy to test out
What happens exactly ?

 

[Garfield1337]

Can't you guess? x)
Obviously,all units damaged by spell will have themselves struck by a chain lightning, looks cool though.

trolololo

 

[defskull]

That flaws...
Why do you even think to do, that ?
Is it necessary to "bug the system and have fun with it" ?
Try to avoid using that action, done.
What if that chance changed to 15% instead of 100%... ?

 

[chobibo]

Garfield's point is that damage detection cannot distinguish between normal attack and ability induced damage. Even if you change the percentage of the chain lightning procuring, spells will still activate the chain lightning, and because we can't determine the damage type, so we really can't "avoid that action" for free. It's not a bug, rather it's the lack of warcraft 3's damage detection API.

Using attack orb effect buffs can solve this problem, but say good-bye to your orb effect abilities and items as these things will conflict with that.

I lol'd at the trolololo!

 

[defskull]

Back to Wazzz's issue for "me muz ordar mah towah to attackz or muv-attackz ferst b4 mah orb-ifek workin`"

Who is trolling, anyway ?
Or are you provoking people to troll by saying, troll ?

 

[akrep_ve_su]

instead of checking every 0.05secs you should use 'Unit takes damage' event.
You have to add this event to the trigger whenever a units enters the map though via Trigger - Add new event: Triggering unit takes damage.

Yes, that's a better method =)

 

[defskull]

Or simply, download my test map, akrep ?

 

[chobibo]

I think you really didn't understand what Garfield just explained and proved to you. He did not do that on purpose, the trigger event unit is damaged doesn't know if the damage was caused by a spell or a normal attack. This is because blizzard didn't give us a function (API) that returns the damage type. I hope you get it now.

And we aren't provoking you.

Are you sure they do conflict? I remember using orb of corruption as both item ability and physical attack detection system; it had no problems (as long as buffs are different)

 

[Garfield1337]

But this system,from what i see,doesn't use an orb ability to detect attacks.

I was referring to this. Also mentioned it in my first post. Aren't we talking about the same thing?

The conflict would be on the damaging unit, there are some orb effects that can't work along other orb effects, specially for melee units. i.e. mask of death and frost orb, one of them won't work, you either would just life steal or just slow.

Oh, that conflict. I see =)

 

[Sh4de]

Is there a way to Order a unit to use a custom ability and not the standard Chain Lightning?

 

[Wazzz]

NO!

Nah, just kidding, I'll check some time, sure it can't be too hard to figure out if there is indeed anything to figure out

 

[Adiktuz]

orb of lightning works fine for me, even if the unit auto-attacks...

Is there a way to Order a unit to use a custom ability and not the standard Chain Lightning?

yup, put the custom chain lightning ability, order the unit to use Orc Farseer - Chain Lightning, and it will cast the custom one...

 

[Sh4de]

Since its a passive, and I don't want this showing up on the unit, could i disable it on the unit and it would still cast the correct ability?

 

[Adiktuz]

you don't need to add it to the real unit if you will trigger its casting... you will make use of a dummy unit to cast the chain

 

[ZlolZ]

I think the trigger could be like this...

Events
Unit is attacked

Conditions
Attacking Unit has item Mjollnir

Actions
Create one dummy unit at attacked unit position
Add spell: Chain Lightning to last created unit
Order last created unit to cast Chain Lightning on attacked unit
Remove spell: Chain Lightning to last created unit
Add a 2 second generic timer to last created unit

This would work, right? I know it's a little simple, but you can upgrade it yourself

 

[Sh4de]

yup, put the custom chain lightning ability, order the unit to use Orc Farseer - Chain Lightning, and it will cast the custom one...

I tried doing this, but the ability isn't casting. Heres the trigger i used,

• Wraith Beam
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • ((Unit-type of (Attacked unit) is A ground unit) Equal to True
    • (Unit-type of (Attacking unit)) Equal to Shadow Wyrm
  • Actions
    • Unit - Create 1 Wraith Beam Caster for (Owner of (Attacking unit)) at (Position of (Attacking unit)) facing Default building facing degrees
    • Set WraithBeamCaster = (Last created unit)
    • Unit - Add Wraith Beam (Effect) to WraithBeamCaster
    • Unit - Add a 2.00 second Generic expiration timer to WraithBeamCaster
    • Unit - Order WraithBeamCaster to Orc Far seer - Chain Lightning (Attacked unit)
    • Unit - Remove Wraith Beam (Effect) from WraithBeamCaster

 

[Adiktuz]

is Wraith Beam Effect the chain ability? if yes then the problem is that you remove it before the unit can even cast the lightning...

else, the dummy might not have enough mana to cast, or maybe the target is invalid...
