How to use: (Tested from 01.HelloWorld)

1. Register loader (before call getmesh)

cpp Code: Select all

CPSKMeshFileLoader* psk_loader = new CPSKMeshFileLoader( smgr );
CPSAMeshFileLoader* psa_loader = new CPSAMeshFileLoader( smgr );
smgr->addExternalMeshLoader( psk_loader );
smgr->addExternalMeshLoader( psa_loader );
psk_loader->drop( );
psa_loader->drop( );

2. use animation from psa

cpp Code: Select all

IAnimatedMesh* animation = smgr->getMesh("Female.PSA");
s32 begin, end;
f32 speed;
((SSkinnedMesh*)animation)->getFrameLoop( core::stringc("Push"), begin, end, speed );
((ISkinnedMesh*)mesh)->useAnimationFrom( ((ISkinnedMesh*)animation) );
node->setFrameLoop( begin, end );
node->setAnimationSpeed( speed );

Happy downloading

There is no direct download from the third link only. The first and second ones are OK.
Trying out the loader.
Thanks.

Very nice, works on Linux with 3 minor changes: Pass all the name parameters as const reference instead of reference, so the following will work on gcc as well:

cpp Code: Select all

 
AnimInfo( const core::stringc& name, s32 begin = 0, s32 end = 0, f32 fps = 30.0f )
void addAnimation( const core::stringc& animationName, s32 begin = 0, s32 end = 0, f32 fps = 30.0f )
bool getFrameLoop( const core::stringc& animationName, s32& begin, s32& end, f32& fps )
 

Thanks for posting!

Hi! Wow! Does that mean we could take ACTORX and produce our own characters? What is currently supported?

Looking at the code this look really simple to use!!

One warning!

cpp Code: Select all

((ISkinnedMesh*)mesh)->useAnimationFrom( ((ISkinnedMesh*)animation) );

This will affect all the instances!!! So it can be only used on a single character and not multiple (we would need to append all the animations to make this work on multiple characters using the same sets of animation)

Really GREAT work! Saw the demo and I'm greatly impressed!!! Thanks also for the link to the web site, they had modeling and texturing guides using ActorX.

Cool, Very nice!!!

Need for work Irrlicht 1.8 :

cpp Code: Select all

 
virtual IMesh *getMesh ( u32 timeMs, io::IAttributes *animationParameters, u32 levelOfDetail=1.0f )
{
return Mesh->getMesh ( 0,255,-1,-1 ); //FIXME need correct Parameters
};
virtual IMesh *getMesh ( s32 frame, s32 detailLevel=255, s32 startFrameLoop=-1, s32 endFrameLoop=-1 )
{
return Mesh->getMesh ( frame,detailLevel,startFrameLoop,endFrameLoop );
};

Yes, tested w/ actorx 249. And thanks for all comment.

- I'm not sure what is your irrlicht svn version ? (didn't test on ios)
- addScaleKey() dont call in loader but why error occurred

Nice! Thanks for sharing

[HellFlip]

Awesome Stuff ! Thanks a lot for this !

The animation system is working fine using Irrlicht 1.7.x, but is broken with Irrlicht 1.8, because of the Irrlicht change "quaternion conversions to and from matrix4 no longer invert rotations."

To fix it using 1.8, do the following change in CUnrealMeshFileLoader.cpp: , in psk_to_irr( psk_t* psk, SSkinnedMesh* AnimatedMesh ):
Change line 396

cpp Code: Select all

core::matrix4 rotationMatrix = joint->Animatedrotation.getMatrix();

To

cpp Code: Select all

core::matrix4 rotationMatrix = joint->Animatedrotation.getMatrix().getTransposed();
