:\ ... 1.)Please specify your title next time, 2.) its actually quite easy. I learned from youtube, I could provide links if you want, but I could only hunt down a few of the ones I saw. Basically you have to make a skeleton in the same location and size to your mesh's limbs. You then parent the skeleton to the model, and then you weight paint verticies to each specified bone (as in you pretty much tell blender which verticies belong to each bone in the skeleton using a 3D painting feature). You then pretty much test it out a little to see if each limb is properlly weighted to each bone, and then you make the animations on a keyframe-timeline scheme. Afterwards, you pretty much do some cleanups on the animation, make it look better, export, etc. I attatched an animation (a .blend file) I once made using Mazz426's
FREE - human base modelGranted it's not the best animation, but I don't think it's so bad, seeing as it was my fourth 3D animation (I think) that I rigged myself and using no references. But then again, that's just me boasting about my "amazing" talents
Quote: "How do [you] add sound to [an] animation[?]"
That much you have to program I think... not sure, I've never gone farther than the animation attatched and shown. Special effects like smoke are just particles of 2D planes that are transparent with the effect, and are just emmited in an order, all the while facing the players camera. This isn't entirely true for all effects, but its a good bit of info. There are always other ways of doing this, so keep an open mind...
