bone animations

Acki · Post by **Acki** » Sun Sep 18, 2005 9:24 pm

Hi,
I had a search and found that there is still no way to set the angles of a bone manualy !!!

So, has someone figured out how to manipulate a bone anim ???

I want to create ragdolls (Newton) and now I have only the choise to create every body part as an single mesh...

I'm doing it with a callback, I set the callback in the scene nodes that pass it as a parameter of getmesh(),that passes it to animateSkeleton().
And of course the callback sets the transformation of bones.
It would be simplier to add a procedure like setBoneRotation, but it is not possible since the meshes are shared between the scene nodes.

Of course you've got to modify the engine. If you like this solution, I'll post some source.

Well, I want to use bones and if there is no other way for...

Yes, post it, please

It would be great, if Nico adds a feature to manipulate the bones to the engine, wouldn't it?

thx, Acki

I've uploaded a zip file with a step-by-step help on how to modify the engine. The complete source of my version of the engine is included if you have some problems with modifications or if I've missed something in the help file.
That's a modification of Irrlicht version 0.10, but it should work with newer versions of the engine (or older).
I hope this can help you.

@acki: I've replied

@omaremad: It's a little bit too rough to be added in Irrlicht

I'll make an example if you like, it will be ready soon.

Well, with your method all nodes, that uses this mesh, are affected !!!
I created a new IAnimatedMeshSceneNode class that supports bone control for every single node !!!

You can download a demo and all changed source files at:

@Niko: sorry for my eMail !!! Well, I have overlooked something, but now it really works !!!

i had the same bug 2

how did u solve it
http://irrlicht.sourceforge.net/phpBB2/ ... php?t=8805

btw
any demos

Will this be added to Irrlicht? I'll change my callback-based code

Now I don't have to make a demo anymore

Btw, I didn't understand it from your previous post (damned beer) : did your code have that bug?

@omaremad: Imho you can solve your problem with Acki's code, the transformations of joints are stored in the scenenodes, use these instead of the transformations stored in the mesh.
