[Spell] Triggered Life and Mana Drain ability.

[Wasabee]

Is there anyway how to trigger a life and mana drain ability. I'm using Physical Damage Detection by looking_for_help.

Can anyone help me?

 

[Nichilus]

Yes it is possible. You have to create lightning from source to target. The best approach is to use custom scripts here, as they allow you to change the value on Z axis for the lightning.
You have the update the position of source and target for the lightning every 0.03 seconds.
Lastly, you have to deal damage in 1 second intervals, catch when DDS detects the target took damage and heal source for the amount of damage taken (iirc, you have to use some function that is present in DDS, so that it actually heals the source)

 

[Wietlol]

If you trigger it... there is no need to use a DDS.
As Nichilus said, you need some visuals to show that it is draining life...
I recommend the lightning system by Maker (if I recall properly) that can attach a lightning to a unit and it will do the work for you.

About the damage, you indeed want some interval but you dont want to use a 1 second timer in a separate trigger that you turn on and off.
That is because that timer doesnt start when you turn the trigger on but at initialization, so if you start draining half way through a second (still relatively small) you will have different moment that it deals damage and it might even have a bonus interval.

For the damage, you can use my Effect Over Time System as it does create a new countdown (no new timer) that will be able to do anything you want.
It also automatically detects if the buff is still present on the target for example.
And you can stop it as well without problems.
You might need some time to find out how it works though.

 

[Wasabee]

I guess it will be difficult. Could you show how it works?

 

[Wietlol]

It is quite something you have to do... no matter how you do it.
I can try to take a look and make it myself when I get home or you can just download those two systems and try to find out for yourself how both work.

 

[Wasabee]

I'll try it when I'm on my PC.

 

[Nichilus]

If you trigger it... there is no need to use a DDS.

IMO a dds is a good choice to heal for the actual damaged caused (since the basic damage can be mitigated), unless your system detects that

 

[Wasabee]

I'm using the Physical Damage Detection System and it said that I should trigger the life drain if ever I'll use it and I'm trying to make a Life and Mana Drain.

 

[Wietlol]

If you just save the amount of life just before you deal the damage and calculate the difference between the original health and new health, you have the most accurate damage calculation that exists.

Triggering the drain itself without DDS is the best IMO.
A DDS is meant to detect damage and do some stuff on the exact same moment.
In this case, you already know the moment so using a DDS can only become worse.

So I need to trigger without DDS.

 

[Wietlol]

Why do you want a DDS?
Where does it fit in how the spell works?
I really am curious about that.
With the exception that the action "Unit - Damage Target" might be replaced by a custom function, it doesnt really matter anything else.

 

[Wasabee]

I'm using DDS on other spells.
It said that I should trigger the life drain and not use the spell in the editor. I didn't meant to say that I should use the DDS in this life and mana drain ability.

 

[Wasabee]

Its difficult how to make this one.

 

[BloodDrunk]

Hey, have you figured out how to do this?
I can help you make this spell. It's easy.

And you need no DDS.

 

[Wasabee]

Well I haven't figured how to do this spell but if you can then I'm grateful.

 

[BloodDrunk]

Ok, I'll give you a trigger and then explain what happens and how should it be done when I get home.

 

[BloodDrunk]

Ok, I made custom Life drain that you need.
This is how the triggers should look. You can edit the damage dealt in the "Life Drain Init" trigger to your needs (just change the number inside, that's amount that will be drained per second).

NOTE that you will have to create custom channel ability (I suppose you know about that ability).
When you create it, just recreate the triggers in here exactly. This is MUI, leakless and looks good.
Duration of this is 10 seconds. If you want to change it, just multiply the duration you want it to be with 34 (because trigger runs 34 times a second) and set that number to

@BD
Target runs out of range
caster gains a new order and thus interrupting his current order
caster is silenced by any effect
target or caster is dispelled
Caster dies
When using lfh's dds, shouldnt you use his custom action?
just a few things to consider...

 

[Wasabee]

Thank you I'll check this out.

You are right. I copied this from my own map, so these things aren't really important to me. But maybe he will need those.
Thanks for the suggestions, I'll update the trigger.

 

[Wasabee]

Sure.

 

[Wasabee]

Please inform me if you've updated the trigger.
