Introduction[]
Currently, there are three known purposes for Line of Sight (LoS):
- Increasing success rate in the detection phase, which allows participation in aerial combat.
- A higher Fleet total LoS (FLoS, or known as Simple LoS) positively correlates with the trigger chance of artillery spotting for a ship's double/cut-in attack in day battle.
- Fleet total LoS is simply the summation of all LoS stats from your ships, including bonuses from the equipment.
- Effective LoS (eLoS), which allows the fleet to reach a specific node (usually a pre-boss or boss node) instead of being diverted to a dead end.
- Effective LoS has been employed in many Event Maps since Spring 2014 Event, Extra Operation Maps (including 1-6, 2-5, 3-5, 4-5), and some World 6 Maps.
- There are special formulas being used to calculate eLoS. As a general consensus, LoS bonuses from equipment (especially reconnaissance seaplanes) are more important than an individual ship's LoS stats.
- See sections below for the currently established formula on how to calculate eLoS.
- Reconnaissance Seaplane equipped on a light cruiser with no plane slots can contribute to LoS.[1] But if it is equipped onto ships and then shot down, it cannot contribute to LoS check performed afterward.
Effective Line of Sight calculation method[]
Formula 33[]
The current standard for LoS routing calculations. It is described as follows[2]:
- is the ship's base LoS
- is the node factor, it represents the weighting of the formula that is known to vary across different maps and nodes. For example, in 6-2, the node factor of Cn = 3 means that equipment is 3 times as important compared to the original formula (as tested in 6-2-F/H). See following section for more details.
- is the equipment multiplier:
- Carrier-Based Fighter: 0.6
- Carrier-Based Dive Bomber: 0.6
- Carrier-Based Torpedo Bomber: 0.8
- Carrier-Based Reconnaissance Aircraft: 1
- Reconnaissance Seaplane: 1.2
- Seaplane Bomber: 1.1
- Small Radar: 0.6
- Large Radar: 0.6
- ASW Patrol Aircraft: 0.6
- Searchlight (Small and Large): 0.6
- Fleet Command Facility: 0.6
- SCAMP: 0.6
- Skilled Lookouts: 0.6
- Sonar: 0.6
- Large Flying Boat: 0.6
- Seaplane Fighter: 0.6
- Midget Submarine: 0.6
- is the displayed LoS value of the equipment
- is the equipment's improvement bonus to eLoS
- This is calculated by multiplying, the improvement multiplier of that equipment, with the square root of the equipment's improvement level.
- The improvement multiplier of Small Radars is 1.25, Large Radars is 1.4, Reconnaissance Seaplanes is 1.2, and Searchlight is 0 (that is, it receives no eLoS bonus when improved)
- This is calculated by multiplying, the improvement multiplier of that equipment, with the square root of the equipment's improvement level.
- is the HQ level. The ceil operation means that the value is rounded up every 2.5 HQ levels.
- represents the amount of ships you have in your fleet.
- It is unknown whether this value increases mid-sortie if a ship disappears from your fleet (e.g. sinking).
Equipment LoS weighting modifier[]
- Also known as node factor
- In some maps, weighting of equipment would be higher than that others.
- It is represented as Cn in the formula.
- For all tested nodes, Cn for 2-5 is 1, for 3-5 and 6-1 are 4, for 6-2 and 6-3 are 3.
- That mean equipment LoS are 3 times more important in 6-2 and 6-3 compare to 2-5 and four time as important in 3-5 and 6-1.
- In other words, ship LoS are less effective in those maps with higher equipment weighting modifier.
- In 2-5, F33(Cn=1) have to be larger than 31 to have a chance to enter boss and 33 to guarantee boss entry.
- In 6-2, F33(Cn=3) have to be less than 43 to guarantee F>H and more than 40 to guarantee H>K
Special Notice to users of KCV v.4.2.5 as well as older version of some other software[]
- Please update your software to a more recent version which patched a calculation mistake.
