Jambe's EVE Online Supplemental Gate & Tackle Info

Supplemental Gate and Tackle Info (related raw data page)

In EVE, all objects in space have radii which entail spheres around them.

for a given object, the distances of other objects are measured from the nearest edges of their spheres to the nearest edge of its own sphere
- objects anywhere inside an object's own sphere are reported to be at zero distance from its perspective. therefore, objects have "zero-spheres" and we can infer the existence of others
  - boarded ships and piloted structures in space have zero-spheres, and celestials like gates and stations and planets and stars have relatively-enormous ones
subcapital ships' radii are often small enough relative to ship speeds & grid scales that their zero-spheres are not hugely consequential to gameplay
- however, when short distances are critical, they can be very consequential! examples: applying/missing or taking/avoiding AoE damage, landing/losing or evading/succumbing to tackle, etc
the radii of all ships are listed here (at right). those of all ships & objects can be seen at e.g. EVE Ref
- smartbomb radii are added to a ship's radius to determine the size of the sphere in which their AoE damage is applied (it can be > 43 km wide for certain Titans with swanky SBs!)

Referencing & Measuring:

the center of a piloted ship can be seen in space by left-clicking its 3d model; a circular icon or "bracket" will appear at the center

to see a ship's distance to the center of an object instead of to the nearest edge of the object's zero-sphere, save the object's location then hover the cursor over the BM

you can also use this trick to measure an object's radius. why yes, all wormholes do have a radius of 3 km
if you're measuring small distances and/or flying a ship with a big radius, it's prudent to subtract your ship's and/or the object's radius, depending on what measurement you're after

EVE rounds meters to nearest km starting at ~10,001 m and it rounds km into decimal AU starting at 10,000,000 km. here are two trivial & skippable observations about EVE's distance rounding:

as you can see in the first clip, there's a tiny sliver of range, perhaps 1 m wide, which gets read out as exactly "10,000 m". dunno what code/mechanism underlies this
- I was moving nearly perpindicular to the gate in that clip, so the distance traveled relative to the gate in either move was much less than 10 m. measuring short distances in EVE is tedious
in the second clip, you can see that EVE's in-space distance readout rounds AU more granularly than the Overview, showing 0.07 AU whereas the overview jumps to 0.1. absolutely unplayable

how close one can get a ship to an object's bracket, i.e. to an object's actual center rather than to the nearest edge of its zero-sphere, depends on the collision models of the ship and object

collision models are invisible and are often markedly different than the visible 3D models
- you can infer the boundaries of collision models by flying ships into objects and noticing when & where bouncing begins
note the links in the Near column of the gates table on the tackle page. these are how close you can get the center of a DIC to the gate's bracket (HICs may be a tiny bit futher out)

Bubbles:

a ship is prevented from warping by a bubble if the bubble is within disruption range of any edge of the ship's zero-sphere

interdiction probes are launched from the center of a DIC's model and have radius 1 m

the smallest DIC (Flycatcher) has a radius of 112 m, and the largest (Heretic) has 144. Eris and Sabre are 138
therefore, if your overview says a ship is "20 km" away, it's actually anywhere from 19,500 to 20,499 m away from the nearest edge—not the center—of your DIC
ergo, it's 19,612 to 20,643 m away from where your probe will be when you launch it, depending on your hull. yeah, we're talking very short distances here, but they make a difference

HIC bubbles project from the center of the ship and their range extends from the edge of the hull's zero-sphere to the disruption range(s) of the WDFG(s)Warp Disruption Field Generators

i.e. a HIC's zero-sphere is added to the range its WDFG(s)

all DICs can completely surround all gates up to and including the Gallente Region

HICs can cover different gates depending on the type of WDFG fitted; a faction WDFG just barely covers the Minmatar Region and the officer WDFG can cover up the Amarr Border

if you're in a bubbler on a gate whose spawn diameter is larger than your bubble, being at its center isn't very useful. being off the collision geometry with a preheated MWD is better

for frequent camping of a specific gate which a bubbler can surround, save a dedicated bookmark as close to its icon as possible. the bookmark can then be warped to and/or approached

note: if you warp directly to a bookmark right on the gate's bracket, you can sometimes get stuck on the model or bounce around. you can jump to get out if necessary

with any bubble—DIC, HIC, or anchored—one should pay attention to positioning, but especially on the larger and knobblier gates

note that various viable gate & bubble type combos produce exceedingly little bubble depth. multiple ships/bubbles is almost always an improvement

smuggler gates are deceptively small. most empire-style Region/Border gates are quite large, but the comparatively-rare smuggler can be easily cocooned by a single DIC

Anchorable Bubbles:

anchorable bubbles, when launched, appear in a random location 1,180 m from a ship's zero-sphere

you can therefore possibly gain or lose a bit of bubble range relative to what you're bubbling depending on where the bubble pops out (i.e. if it appeared towards or away from what you're bubbling)
- as an example: if anchoring bubbles in a Mammoth—the largest subcap Hauler—there is a 3,594 m-wide sphere around the center of the ship on which bubbles will appear in space

all types & sizes of anchorable bubble have radius 70 m; ergo, from an anchorer's perspective, the edge of an anchored bubble's disruption zone will be at its disruption range plus 1,250 m (1,180 + 70)

one T2/faction large anchorable bubble can envelop all gates up to and including the Caldari Region

the check for this is whether bubble radius > gate radius + max spawn radius + 5 km (5 km is the minimum anchoring distance)

Scripted HIC tackle:

HIC points/scrams prevent all

capitalCarrier, Dreadnaught, Force Auxilliary, Rorqual, Jump Freighter (not regular Freighter)

and

supercapitalSupercarrier, Titan

ships from jumping stargates, but not Ansiblexes (excepting regular i.e non-jump freighters and orcas, which could be classed pseudo-capitals)

HIC points/scrams prevent all ships from jumping Ansiblexes as of this March 2025 patch
- subcaps can still jump stargates under HIC point/scram, and all ships can jump stargates if bubbled (assuming no HIC point/scram). chart about these mechanics

regular scrams, HIC scrams, and HIC points prevent activation and cancel spooling of MMJUs and MJDs and MJFGs/booshes

regular points and bubbles do not
