Problem Loading X Hierarchy

Tiege · 2011-08-21T17:08:29

I'm attempting to load and render an animated X file. I managed to get a static model loaded and rendered but I'm having issues with the animated one. Right now my issue is that my pFrameRoot becomes Null right after the D3DXLoadMeshHierarchyFromX function. I ran it in debug to check the values and during the function call it had values for pFrameRoot but the very next line (i put in an empty if statement to check it) the same variable becomes NULL. The Load mesh function doesn't fail, I used another if statement to check that. But I can't tell why my pFrameroot is going to NULL; My code is completely horrible and sloppy since I'm just trying to get things to run not to make it clean or developed. I don't even know if it's capable of loading the file properly since I left out a lot from the X file animation tutorial on this website. But I really just want to get tiny.x rendered and walking. I'm leaving out the textures and skins and other unnecessary (i hope) things which I can fix and implement later. #include <windows.h> #include <d3dx9.h> #include <MMSystem.h> #include <dinput.h> #include <d3dx9anim.h> #include <d3d9.h> // #define KEY_DOWN(vk_code) ((GetAsyncKeyState(vk_code) & 0x8000) ? 1 : 0) // #define KEY_UP(vk_code) ((GetAsyncKeyState(vk_code) & 0x8000) ? 0 : 1) //globals LPDIRECT3D9 d3dObject=NULL;

heres your problem.

But I really just want to get tiny.x rendered and walking. I'm leaving out the textures and skins and other unnecessary (i hope) things which I can fix and implement later.

I think you will need the skin ifo thats where the frames are its maybe loading a static mesh only.

Hey, I couldn't reply again yesterday, but I meant to say I haven't gotten to the part where I draw the whole mesh. I'm only loading the bone hierarchy (which was the OP's original problem. I'll try to draw the entire mesh today.

I'll give it a shot, I thought skins were just how the textures should be applied onto the model? ...hence "skin"

Any luck on that?
