what is framecount?

[NewerCookie]

i animated skinning model that is b3d format on irrlicht 1.5
it seems not smooth because endframe skipped
model was made by 3ds max that has 20frame animation
i think.. all framecount must be 21(0~20)
i checked "PositionKeys.used" has 21

Code: Select all

u32 CSkinnedMesh::getFrameCount() const
{
	return core::floor32(AnimationFrames);
}

seems like CSkinnedMesh::getFrameCount() function returns 'all framecount'


then.. i have been confuse this line( CSkinnedMesh.cpp,793 )

Code: Select all

AnimationFrames=AllJoints[i]->UseAnimationFrom->PositionKeys.getLast().frame;

AllJoints->UseAnimationFrom->PositionKeys.getLast().frame returns 20.
ok. lastframe is 20, right.
but, it means framenumber? framecount is different from framenumber?

please, answer me..

We have a bug open against frame counts. Hopefully hybrid has made some progress in figuring it out - I'm fairly clueless about these new-fangled "animated" models.

I hope this bugtracker is assigned to Luke, because I'm not much into animated meshes either. I just write the loaders, but if my intuition and the values I pass are correct is not clear...

thanks answers.
I made makeshift

CAnimatedMeshSceneNode.cpp, 519Line

Code: Select all

const s32 maxFrameCount = Mesh->getFrameCount() - 1;

Code: Select all

const s32 maxFrameCount = Mesh->getFrameCount();

it's temporary repair endframe skipping problem..

I noticed this problem too, exporting out .X files from Max.
Instead of messing with the numbers Irrlicht gave me, I just exported out an additional frame at the end.
Maybe its something weird with Max? Might be worth experimenting with Blender or other programs to see if irrlicht gets it right or not.

Oh, i used that but maybe artist hate..
I had rather fix engine than..
