Hello, I am an absolute beginner to 3d programming in general, more specifically DB. I'm not even sure if this question is specific enough to have even a general answer but here goes...

How do you reuse animations for different models? an example of what I mean is for instance a pro wrestling game in which moves can be assigned to wrestlers, obviously animators do not redo the same punch animation once for every wrestler model, there is just one and it is applied to different models right?

I understand the vaugness of this question and would not expect a DB specific answer, but if anyone can enlighten a bit as to how this process works I would appreciate it greatly.

Thanks in advance.

What if you made one basic model, then distorted its dimensions and gave it different skins to make your various characters?

What it is is that they have 1 skeleton that is used in every model. Now, this model can be animated in every move you want it to, then import it into the next wrestler. rince and repeat and you have a gang of wrestlers that can look different, but still be based off 1 skeleton and can do many a move,

What I'm wondering is when there is a size difference between models, a good example is in "Tenchu: Wrath of Heaven" when the girl uses the magic disguese spell. Those Guard models are taller than her by about a foot, the same bone skeleton couldn't be use for the two of them.

Most, if not all, skeletal animation is done entirely through rotations. Either IK or FK based animation is going to be mostly keyframing rotations of bones around pivots, the actual length of the bones never (rarely) change.

So you are half right and half wrong. They are probably different skeletons but the same animation set.

So it doesnt really matter how tall or short the different skels are, just the rotation of each bone in comparison to the other bones in the system to get the animation. So you can use one animation set with any bone system.
