[Trigger] AoE = How much.

[Airandius]

Oke, I suck at making good titles.

Let's say I create a spell with "A" AoE, let's say it's 1000.
I then proceed to create a dummy at that point and let it pick the units in this area.
For this I use, units in range. But what range do I need to use in order to match with the AoE the spell will show.

I would love if somebody could tell me the formula or at what ratio I should look it like:

Ratio Example:
1000AoE = 580 range
500AoE = 265 Range

Formula Example: (Math please, no wc3 math.)
( "AoE" x 1.5 ) + 20 = "Range"

(I know that these examples are wrong, that's what I'm asking. That somebody shows me what the real values are.)

to be precise it would be the radius of the circle plus half of the unit's collision size, so for an AOE 1000 units wide, it would be 516.

This is because the triggers select units if their centers are in range, but hardcoded AOE spells will hit units whose edges are in range.

Keep in mid that units with larger than 32 collision sizes will be excluded if they are on the very edge.

Range = 0.5(AOE + collision zie)

I would recommend something like this:

call GroupEnumUnitsInRange(g,x,y,RANGE+SAFETY,Filter)

//the filter func:
function FilterFunction takes nothing returns boolean
    return IsUnitInRangeXY(x,y,GetFilterUnit(),RANGE)
endfunction

this is because GroupEnumUnitsInRange is bugged, or something. IsUnitInRangeXY takes collision in it's calculations..

Oh yeh, I forgot to mention: "Jass = bullcrap" to me. I know it's better, I know it's 'easier' but I just hate coding. Can't read it, can't write it. No way I ever will.

@ tml616
Hmm, so let's say the casting dummy has 0 collision and I cast a spell with 500 AoE.
I need to pick units in (500 + 0 = 500) 0.5 = 250.
Correct? (Because it is a dummy that's placed in the center of the AoE that will cast the actual spell on everything inside the AoE of the casting Hero's spell.)

Ok,

• Set TempGroup = Units within XXX range of (Location)

that bugs, i dont know how, but making XXX larger than your wanted range, and checking via Custom Script (IsUnitInRangeXY) deals with that..

Ge ken de groeten uit brabant krijgen, Kut! xD

 

[tml616]

Yes the range is just the radius of your AOE circle. But the collision size of the targets is what matters. So if most of the units on your map have 32 collision size, it would be radius + 16.

But Jass and me don't like each other. Anyway, I'll just use yml616's way, I don't care about the precise things etc.

Oh and Yixx, I don't use a tempgroup, I just use the bj_wantdestroygroup thingy for this spell. =)
