How do you trigger damage in a line? (GUI)

[Arcsol]

I started wondering how people can make triggered damage in a line or cone (Shockwave, Carrion Swarm, etc.). I usually make the cast from Breath of Frost, and since it gives a buff, I trigger to pick units in a great distance (like 1000) from the selected point Matching they have said buff, then the Picked units take the damage and the buff is removed.

Maybe is there a better way to do it? With Regions maybe?

Line equals to Shockwave, not Carrion Swarm, those ones imply a cone-shaped area.
For a line conversion, you can use this: http://www.hiveworkshop.com/forums/...ls-279/chapter-1-static-shapes-gui-7337/#four
and pick every unit within 128.00 of the said points (add them in a variable, apparently that tutorial doesn't clear the leaks created). Make sure you check if the picked unit already is in a unit group, if not, add it. This will prevent the unit from getting damaged twice by the same ability. You can use a local group to add the units or recycle the groups by using a global array'd variable with the:

• Custom script: if udg_UnitGroup[udg_Increment] == null then
• Custom script: set udg_UnitGroup[udg_Increment] = CreateGroup()
• Custom script: endif

Maker has created an imitation of Carrion Swarm, that forms itself periodically: http://www.hiveworkshop.com/forums/spells-569/lich-king-spellpack-v1-03-a-157830/
The ability is called "Distortion Wave".

Hmm that was kind of my second thought, though I never realized to check if unit is already in group. And I know carrion swar and such are cones, but you can modify their final area so they count

and pick every unit within 128.00 of the said points

When you say this, I suppose 128 is the AoE I want for the Shockwave, right?

EDIT: I already read the Spell you suggested me, and I think everything's clear now. Thanks for the help.

Yep, that's the AoE.

Thanks for the help. Just wondering is may way of doing it inneficient then?

 

[Pharaoh_]

Inefficient? Why would want to do that?

 

[PurplePoot]

More so overcomplicated than anything.

Sorry I mispelled, what I meant was if the way I do it was inefficiente (via Buff check)
It ocurred to me to debug the use of the buff way, and it seems to work okay, don't know if it's as efficient as the whole triggered way though.

More so overcomplicated than anything.

Regarding? o.o

 

[Pharaoh_]

Buff check doesn't make it MUI, you can't detect the source of the buff, unless you customize it.

It's more so overcomplicated than inefficient. Don't use dummy spells if you don't have a very good reason to, and I'd say that doesn't qualify as a very good reason.

 

[Arcsol]

I understand. I'll not use buffs then.
