# can only use real variable when dealing damage to an area?

I need to find a way to deal area damage based on a passive ability.
so... what i have so far.... unit cast blink to a point then i have

Unit - Cause (Casting unit) to damage circular area after 0.00 seconds of radius 500.00 at TempPoint, dealing (10.00 x 1.00) damage of attack type Spells and damage type Normal

what i want
dealing damage using arithmetic: 10 x level of this ability for casting unit

problem is arithmetic will only allow me to use real variables not integer.... so how to do this?

You can convert reals to integers and vice versa. There are actions for that.

ok found the action it was under conversion

how ever i dont know how it should look exactly...

Set RakshirIntiger = (Level of Power (Tal'darim High Lord) for (Casting unit))
Set RakshirReal = (Real((Level of Power (Tal'darim High Lord) for (Casting unit))))

do i need both of these or just the second one?

Setting variables depends on what you're doing ... if you're going to be using it more than once, then yes, set them

If you only use it once, it might not be worth setting up a variable (unless it's simply for legibility).

If you don't use it at all, don't bother

Cheers!

I have a blink ability that deals damage to all units in the area targeted. the damage is based on the level of the casting units ability "power" so its unit finishes casting ability then pick all units in 600 area and deal damage = to 10 x level of casting units power ability.

Code:
``````Brink Damage
Events
Unit - A unit Finishes casting an ability
Conditions
(Ability being cast) Equal to Brink (Tal'darim Highlord)
Actions
Set TempPoint = (Target point of ability being cast)
Set RakshirIntiger = (Level of Power (Tal'darim High Lord) for (Casting unit))
Set RakshirReal = (Real((Level of Power (Tal'darim High Lord) for (Casting unit))))
Unit Group - Pick every unit in (Units within 700.00 of TempPoint matching (((Owner of (Picked unit)) is in (All enemies of (Owner of (Casting unit)))) Equal to True)) and do (Actions)
Loop - Actions
Unit - Cause (Casting unit) to damage (Picked unit), dealing (10.00 x RakshirReal) damage of attack type Spells and damage type Lightning
Custom script:   call RemoveLocation (udg_TempPoint)``````

is this right? i doesn't work what am i missing??

FOUND IT...

not sure why but the problem was with unit finishes casting ability event....

it needed to be starts to cast.... not sure why... i had another trigger for the same ability that works just fine with finishes casting... well what ever this is better than that.

This works!! blink ability that does area damage!
Code:
``````Brink Damage
Events
Unit - A unit Begins casting an ability
Conditions
(Ability being cast) Equal to Brink (Tal'darim Highlord)
Actions
Set TempPoint = (Target point of ability being cast)
Set RakshirReal = (Real((Level of Power (Tal'darim High Lord) for (Casting unit))))
Set RakshirIntiger = (Level of Power (Tal'darim High Lord) for (Casting unit))
Unit Group - Pick every unit in (Units within 700.00 of TempPoint) and do (Actions)
Loop - Actions
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
((Picked unit) belongs to an enemy of (Owner of (Casting unit))) Equal to True
Then - Actions
Unit - Cause (Casting unit) to damage (Picked unit), dealing (10.00 x RakshirReal) damage of attack type Spells and damage type Lightning
Else - Actions
Do nothing
Custom script:   call RemoveLocation (udg_TempPoint)``````

You should use "Starts the effect of an ability".
The problem with "Finishes Casting an Ability" is that by the time the ability has finished casting the (Target point of ability being cast) doesnt exist anymore. The ability is over. There is no target point. That is why your previous trigger didnt work the way you wanted it to. It probably dealt damage to units around the center of the map because that is the default location if a point does not exist.

How can you tell the difference between real traffic and indexing or AI generation bots?
• The Helper:
The bots will show up as users online in the forum software but they do not show up in my stats tracking. I am sure there are bots in the stats but the way alot of the bots treat the site do not show up on the stats
• Varine:
I want to build a filtration system for my 3d printer, and that shit is so much more complicated than I thought it would be
• Varine:
Apparently ABS emits styrene particulates which can be like .2 micrometers, which idk if the VOC detectors I have can even catch that
• Varine:
Anyway I need to get some of those sensors and two air pressure sensors installed before an after the filters, which I need to figure out how to calculate the necessary pressure for and I have yet to find anything that tells me how to actually do that, just the cfm ratings
• Varine:
And then I have to set up an arduino board to read those sensors, which I also don't know very much about but I have a whole bunch of crash course things for that
• Varine:
These sensors are also a lot more than I thought they would be. Like 5 to 10 each, idk why but I assumed they would be like 2 dollars
• Varine:
Another issue I'm learning is that a lot of the air quality sensors don't work at very high ambient temperatures. I'm planning on heating this enclosure to like 60C or so, and that's the upper limit of their functionality
• Varine:
Although I don't know if I need to actually actively heat it or just let the plate and hotend bring the ambient temp to whatever it will, but even then I need to figure out an exfiltration for hot air. I think I kind of know what to do but it's still fucking confusing
• The Helper:
Maybe you could find some of that information from AC tech - like how they detect freon and such
• Varine:
That's mostly what I've been looking at
• Varine:
I don't think I'm dealing with quite the same pressures though, at the very least its a significantly smaller system. For the time being I'm just going to put together a quick scrubby box though and hope it works good enough to not make my house toxic
• Varine:
I mean I don't use this enough to pose any significant danger I don't think, but I would still rather not be throwing styrene all over the air

I bitch about Xenforo sometimes but it really is full featured you just have to really know what you are doing to get the most out of it.
• The Helper:
It is just not easy to fix styles and customize but it definitely can be done
• The Helper:
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
