[edit] Overview

Ion Cannons are a defensive building that can be built in Ground Bases for defense against starship attacks in a Space Combat.

[edit] Space Combat Details

  • Uses 10 ord per shot
  • Each Ion Cannon adds to the base energy production
  • As of Host 213 , base ion cannons can fire through its own active Base Shield under certain conditions.
  • These target ships do not have to set to attack ground (what is the case for wings and aa guns)
  • Each ion cannon is active only 50% of the time
  • The chance that a single shot will not miss the target is: 
MAX(Base Ion Cannon Odds – Holo Decoys of TargetPlayer/30;20) x
MAX(MIN((200-TargetsEvasiveMod)/100; 1);0.1) x
(0.8 + 0.2 * (1 - TargetDistance / Base Ion Cannon Range))

' * Ships with an evasive factor of more than 100 are more difficult to hit
' * At point blank the evasive factor of the target can steal at max 90% of the accuracy
' * At max range still 80% of the point blank accuracy are available
  • Odds that a PD will intercept the shot are: Base Ion Cannon PD Odds + PDiBonus
  • An activated Exotic Tech Ion Deflectors will help the PD by blocking 90% of the shots which could not intercepted by the PD.

[edit] Hit!

  • If a shot really impacts then with a chance of 10% a radial bump of 1800/(hullmass+1) is added to the radial velocity. The target also gets 30 ticks added to its point of time when a new course correction is possible.
  • A succesful hit inflicts damage to shield, but not to armor and to hull and system
    • Shield drain is always 14
    • Ion Cannons have an armor arc of 6000, so the inner of ships with more armor is permamently protected
    • With a chance of hullmass/10.000 the hit will inflict 0.2 hull damage
    • With a chance of SysMod/500 the hit will inflict 0 to 2 system damage ( Round(20*RND;0)/10 (0, 0.1, 0.2,..., 1.8, 1.9, 2) )

[edit] Racial Adjustments

  • If a CoT ship's armor or hull (shields gone or no shield at all) is hit by an Ion Cannon, there is a chance that 2 crew, 8 troops are killed.
    • The chance depends on the amount of Armor present on the CoT enemy ship and variying from 0% (full Armor) to a max of 25% (no Armor) 
Chance = 25% - (Armor / MaxArmor) * 25%

[edit] HConfig Settings

  • Base Ion Cannon Range (Default: 500)
  • Base Ion Cannon Charge (Default: 100)
  • Base Ion Cannon Odds (Default: 30)
  • Base Ion Cannon PD Odds (Default: 40)

[edit] Special

  • Enemy players must have 3 ships plus half the square root of the base's Ion Cannons (3 + SQRT(Ion Cannons / 2) to blockade a planet.
  • Starting HW have 20 Ion Cannons, 6 ships are needed to blockade a HW.
