DirectX Skeletal animation from *.x a file

[Alex BP]

Who can will prompt as to load skeletal animation from a file *.x
I try to make it with the help invoke D3DXLoadMeshHierarchyFromXA, the program takes off. I suspect a problem in correct definition of interface ID3DXAllocateHierarchy.
Who can the problem knows in what?

Paste the code.

You speak very good England.

hitchhikr,

Sarcasim doesnt come across well in text if being sarcastic is what you meant by writing "You speak very good England.".
Otherwise I guess you were just being mean.

I'm not beeing mean here, proof: i'm even willing to help you to understand the difference between sarcasm & irony

Implementing such stuff in asm is going to be rather cumbersome since it's usually created as C++ classes.

This may or may not work:
(Btw, there's no need to use GlobalLock when GlobalAlloc is used with GMEM_FIXED).

Code Select Expand


    invoke  GlobalAlloc, GMEM_FIXED, 4
    mov Allocate_Hierarchy,eax
    invoke  GlobalAlloc, GMEM_FIXED, 4 * 4
    mov Class_VirtualFunctions,eax

    mov eax,Allocate_Hierarchy
    mov ebx,Class_VirtualFunctions
    mov [eax], ebx
    mov [ebx], offset CreateFrame
    mov [ebx + 4], offset CreateMeshContainer
    mov [ebx + 8], offset DestroyFrame
    mov [ebx + 12], offset DestroyMeshContainer

    invoke D3DXLoadMeshHierarchyFromXA, CStr("models\sample.x"), D3DXMESH_MANAGED, lpD3DDevice, toto,NULL, ADDR m_pFrameRoot, ADDR m_pAnimController


Methods need to be implemented like that:

Code Select Expand


CreateFrame proc pThis:dword, szName:dword, pNewFrame:dword
    mov eax,D3D_OK
    ret
CreateFrame endp

CreateMeshContainer proc pThis:dword, szName:dword, pMeshData:dword,
                                           pMaterials:dword, pEffectInstances:dword,
                                           NumMaterials:dword, pAdjacency:dword,
                                           pSkinInfo:dword, ppNewMeshContainer:dword
    mov eax,D3D_OK
    ret
CreateMeshContainer endp

DestroyFrame proc pThis:dword, pFrameToFree:dword
    mov eax,D3D_OK
    ret
DestroyFrame endp

DestroyMeshContainer proc pThis:dword, pMeshContainerToFree:dword
    mov eax,D3D_OK
    ret
DestroyMeshContainer endp


You better switch to C++ if you want to deal with such kind of stuff.

hitchhikr, thank!

I do not like C++ and classes. I like ASM!
