To activate the cloaking device, set the mission to Cloak. This implies you can not tow, intercept, lay mines etc. while cloaked. When your client program won't let you set the Cloak mission, you can also use the Cloak extended mission (via the extmission command possibly) which does exactly the same.
Bird Men that do the Super Spy mission will also cloak when possible.
This standard cloaking device burns fuel to operate. The fuel consumption is Trunc(HullMass * CloakFuelBurn / 100), where hulls lighter than 100kt count as 100kt. After burning that fuel (and the fuel needed to move), at least one kiloton must remain in the fuel tank.
Cloak fuel is burned before movement. When you have too little fuel to support cloaking and movement, the fuel is burned completely and cloaking fails (because movement will consume all fuel so there's nothing left). Cloaking alone will not empty your tank, though. If you have less than X+1 kt fuel, the cloak will not happen at all, and all fuel will be left there.
Cloaking has the following benefits:
- You can not be seen by others;
- You can not be attacked by others, but you can yourself attack (by setting a Primary Enemy, config option AllowCloakedShipsAttack). You can not attack planets when cloaked, though;
- The risk to trigger a subspace mine is lower when you're cloaked;
- ...plus some other goodies.
Combinations:
- Cloak + Ramscoop
- ►
(4.0i/3.4k) The Ramscoop produces only half the normal amount of fuel while the ship is cloaked.
- Cloak + AntiCloak
- ►
(4.0i/3.4k) Anti-Cloak ships do not decloak themselves.
- Cloak + Hyperdrive
- ►
(4.0i/3.4k) Hyperjumping frees large amounts of energy. Therefore, ships which hyperjump must decloak.
- Cloak + Chunneling
- ►
(4.0i/3.4k) Building up a chunnel sets free huge amounts of energy, therefore both Initiator and Mate have to decloak.
Preconditions for cloaking:
- Ship has cloaking device (of course!);
- Ship has fuel (CloakFuelBurn per 100kt ship);
- Ship has the Cloak mission or the Cloak extended mission, or ship belongs to Bird Men and has the Super Spy mission, the Special mission, or the Standard Spy mission;
- Ship is not too badly damaged (DamageLevelForCloakFail);
Cloak Failure: Cloaking can fail under certain circumstances:
- Random failure (technical malfunction, CloakFailureRate);
- Too little fuel. May happen due to robbing, web minefield fuel draining, and in certain movement situations.
- Tachyon field (Anti-Cloak ship). Note that up to version 4.0h/3.4j, an Anti-Cloak ship would have de-cloaked itself all the time;
- Wormhole travel;
(4.0i/3.4k) Ship does hyperjump, initiates a chunnel, or acts as a chunnel mate;
- Ionic pulse triggered by Super Spy;
- Ship gets too badly damaged. Ships which get over the damage limit by a mine hit or glory device must immediately de-cloak. Damage taken in combat can be repaired and does not de-cloak the ship. In particular, a ship which enters combat cloaked will not decloak for the rest of the fight when it gets damaged;
- Ship is affected by an ion storm.
An easy rule-of-thumb is that cloaking devices are only turned on once at the beginning of the turn. Afterwards, cloaking may fail for various reasons, but it may not be restored.
