Can this be done with Channel?

[tml616]

I want to make some channeled spells that have an upkeep cost, and some other stuff. The best example I can think of is if you every played Warhammer Online, there is a spell called Withering Heat. How it works is this:

-Caster loses 13 mana per second
-Channels up to 6 seconds
-Damages and slows target while it's being channeled

Another example would be Mindflay from WoW.

I am wondering if I can do this with a spell based on Channel, by having the Follow-Through Time set to 6 seconds, and giving it one of those invisible buffs that goes on the caster of a channeled spell. Or will I have to base it on some other targeted channel like Drain?

I guess I'm just not so sure what Follow through time is.

 

[Silvenon]

Follow through time determines whether the spell is channeling or not. So both duration and follow through time should be set to the duration of the spell.

Here's a tutorial I found just now. Maybe it'll help a bit.

i guess this it what you are thimnking of

1. Leaks position
2. Multiple Integer A cause bugs
3. Why you remove the buff from Triggering Unit when you have set it into a veriable?

Don't confuse the guy, this not even close to what he wanted, and the spell should be targeted, if don't know what "Like Mindflay from WoW" means, try google it.

1. Leaks position

qft.
About time people learn it ^^

2. Multiple Integer A cause bugs

Well, actually: it only bugs when 2 Integer A-loops are used inside eachother, or in different triggers (when activated at the same time), when in the same trigger they don't bug.
However, using "For each integer Variable" is a far better idea, as Integer A (and B) are BJ's and therefore slower.

So you were partially right: Integer A isn't good ^^

Apart from these things, the spell isn't MUI, so if it is used multiple times by the same player it will bug.
(Yeah, okay... this might be for an RPG, but who knows?)

Ill give this a try and get back to you.

 

[tml616]

I really can do it myself with hashtables, just wanted to know if I could base the spell on Channel or if I had to already use a spell that gave the caster a channeling buff like life drain

 

[DragoonZombie]

To answer you question: Yes you can use Channel.
I would set the cooldown longer than 6 seconds or else the user will be able to cast it again after finishing without waiting.

To detect if the unit finished/stopped the ability while casting you simply do:

• Trigger
  • Events
    • Unit - A unit Stops casting an ability
    • Unit - A unit Finishes casting an ability
  • Conditions
    • (Ability being cast) Equal to Skill
  • Actions
