Modding SW3?

Yes Rastix, but if the XML schema files weren't hardcoded this needn't be the case. I might be wrong on that last bit though, iirc Nanaki mentioned something about needing to edit them for custom perks.

Edit:
I'm doing a hella lot of editing on this forum, lol. But I dislike multiposting, it just looks messy.

Anyway... just some figures on missile jamming and effective antijamming values. Here's a quick recap of the formula in \Data\Scripts\AI\JamRocket.script:

function JamRocket(jamPower, antiJammer)
	local pomeha = jamPower + 10 - RAND(30);
	return pomeha > antiJammer;
end;

Basically we're given a 1 in 30 chance against the difference between an ECM/ACS's jamming value versus a missile's antijamming. That function takes in the jamming and anti values, and simply returns true or false.

(jam 10)
at anti 10 --> 20-X>10 for (0-9 out of 30) i.e. 33%
jam 10 fails for all anti 20+

(jam 20)
at anti 10 --> 30-X>10 for (0-19 out of 30) i.e. 66%
at anti 20 --> 30-X>20 for (0-9 out of 30) i.e. 33%
jam 20 fails for all anti 30+

(jam 30)
at anti 10 --> 40-X>10 for (0-30) i.e. 100%
at anti 20 --> 40-X>20 for (0-19 out of 30) i.e. 66%
at anti 30 --> 40-X>30 for (0-9 out of 30) i.e. 33%
jam 30 fails for all anti 40+

(jam 40)
at anti 20 --> 50-X>20 for (0-30) i.e. 100%
at anti 30 --> 50-X>30 for (0-19 out of 30) i.e. 66%
at anti 40 --> 50-X>40 for (0-9 out of 30) i.e. 33%
jam 40 fails for all anti 50+

Missile antijamming and a jammer of the same level equates to a 1-in-3 chance, and each point of jamming roughly adds 3.3% effectiveness.

We have 5 levels of antijamming on missiles, starting from 0 (no antijamming), 10, 20, 30, and 40. The alien missiles and torpedoes are rated 50 btw so technically they're supposed to be unstoppable. As you can see, anything rated 2 levels below (ECM/ACS=40 versus missile antijamming=20) is always countered, and anything 1 level above (ECM/ACS=20 versus missile antijamming=30) always passes.

So with the best antijamming equipment (rating 40), you'll always stop at least 3 classes of missiles (no jam, 10, and 20), 1 in 3 chances of getting hit by a missile rated 30, and 2 in 3 chances of getting hit with a missile rated 40.

Hmm, the figures aren't bad. Not too strong, and not useless.
