books on animation?
You have the theoretical knowledge (what makes an animation look good) and you have the practical knowledge (how to use Maya etc. to make an animated sequence).
For the practical knowledge you can search for a book or other learning material on your preferred software suite.
For the theoretical knowledge, you can get a copy of "The Animator's Survival Kit," one of the most recommended books in the field:

I wouldnt waste your time with books. Purchase a subscription to digitalTutors.com and you will be 100% happy with the return. Everything you would ever need to know about animation.
The reason a cartoon animation book was linked was because good animation, whether game or screen media, applies the same core principles. It's been a mistake made by game animators in the past to ignore the huge leaps made by traditional animation; if you want to have impactful and good animation that conveys any feeling whatsoever, buy that book. It's also a great read. 
If you were looking for technical knowledge on literally what buttons to press; buy Digital Tutors, too. Great resource.
Though, I think you're more likely to find some good references on swordfighting animation systems looking up devblogs or finding tutorials online, honestly.
back in the day, "character animation and lighting" volumes one and two were quite good. wish i still had them...

It may have been a while since you browsed their inventory of videos. They have design concepts, animation tricks of the trade, scene setup, key practices for making clean and elegant rigs/animator control schemes, and countless other tutorials that are NOT just geared to "pressing buttons". There is something to be said about reading a book sure, but for myself (and maybe others) seeing something in a real sense makes it that much easier when learning.
Once you transfer the footage to your computer, you can go frame-by-frame on it with a player like Media Player Classic - Home Cinema (which has frame-step controls) and study how everything is moving - timing, rotation etc.
This helps you get better results in a shorter amount of time. You will also learn a lot from this analytical observation.
