Controlling bones by code, multiple animations & speed

SysOp · 2013年3月22日

Hello,

First of all, awesome program and lib!

I've got a few questions.

A - How is it possible to say, make the head look at X? Lets say the character is holding a gun and is pointing it at X position. That involves a lot of bones. I noticed you can pick a bone and rotate it, but is there a proper way to do this for all bones?

B - Is it possible to control the legs of a character and the torso separately? Say the torso is doing animation A, while the legs are doing animation B.

C - What is the proper way to control the speed of some animation? Lets say, a slower run, faster run.

D - Editor wise: Is there planning IK? Lets say, to move a hand up, I grab the hand bone, translate it up, and all the childs will move properly (instead of rotating 3 bones like right now).

E - Editor wise: Is there a way to limit the angle of a bone? Lets say, I want to limit how much a leg can bend.

That would be all. I know is too much Thanks in advance :* !

Adjust the amount the animation time changes:

Use the Pose tool, drag a box or ctrl/cmd click to multi select the bones you want to manipulate, then drag those bones.

Nope. 4/5 isn't bad! :clap:

Awesome, thanks for the quick explanation. I think that the POSE mode must be featured, I noticed in all videos it was never used. It is a BIG advantage against traditional FK. I just happened to ask and a big smile appeared on my face when I discovered that it worked the way I wanted.

Cheers!
