I find myself completely failing to understand stealth, at least with regards to building stealth into one's ships.
I have a bio-adaptive hull here which is listed as having a stealth of 30. I want to use it to build a super stealthy scout ship. I have both the electromagnetic damper and phasing cloak available to me. However both of those two technologies list as having a strength of zero. If I put either of them or both, the listed stealth of my scout does not change, it stays at 30.
What am I missing here? Do these technologies actually make one's ship more stealthy, or are they just non-functional place holders right now? Would the effect of the two be cumulative of one installed both electromagnetic dampers and phasing cloaks, or does the higher tech of one over ride the other? Can one stack multiple copies of the same highest level tech in order to boost the effectiveness? (Of course scanner tech should be similarly boostable if so.)
Yeah, it is a bit of a pain... Actually, those two questions are very much related. The default for ship parts is that the effect stacks, so if you add the bonus by entering it in the "capacity" field of the part description, then you would be able to put on 5 phasing cloaks and get 5 times the phasing cloak bonus. To avoid that, I put the bonuses for those in an effectsgroup with an appropriate stackinggroup associated with the ship part, which doesn't show up in the design screen, but will show up on your ship after the fact. Only one bonus is used, and I'm not sure I took any measures to ensure it's the best bonus, so mixing EM Damper with Phasing Cloak is not a good idea.
If you're ever in doubt about whether something actually does anything, go to the options menu under UI and turn on Auto-Generated Effects Descriptions. Then some auto-generated text appended to the end of its description will tell you, albiet in a verbose and occasionally abstruse way, what the thing actually does, if anything.
