CreateFrame creates some sort of infinite loop?
Author
Heres my createframe implementation:
As you can probably guess it isn't working, everytime I try to create a frame (in a seperate calss) it gets me stuck on some sort of loop or just crashes. Usually it crashes and gives me an unhandled exception error though it does get stuck on infinite loops sometimes...
I don't know whats causing it so umm, any help?

Ok, the infinite loop turns out to be something else entirely (not in the code above) and I can't be bothered fixing it today so I've just taken it out (for the time being).
I'm not sure if I'm doing this right but heres what I have so far:
H->CreateFrame is what is making it crash, when I run the code it gives me an unhandled exception error.

Translation: The instruction in your compiled code at 0x0040234e tried to read from address 0x00000000.
In other words: You have a null pointer you tried to dereference. Why isn't H being initialised at all?

ID3DXAllocateHierarchy is an abstract class so ID3DXAllocateHierarchy* H = new ID3DXAllocateHierarchy doesn't work.
I'm doing this for the first time so the problem is probably pretty obvious, I might just be missing something.
I thought D3DXLoadMeshHierarchyFromX actually initialized H.
ok, when I use the following code:
D3DXFRAME * newFrame = new D3DXFRAME;
H->CreateFrame("frame 1", &newFrame);
I get the following error now: "Unhandled exception at 0x0040213f in shapes2.exe: 0xC0000005: Access violation reading location 0x00000050."
I think I changed the model it was loading, since the original one (tiger.x) didn't have any animation bones so I thought that might have been causing the problems.
Could the problem actually be here?
ppMC is of type D3DXMESHCONTAINER* wherein MC is D3DXMESHCONTAINER_EXTENDED. D3DXMESHCONTAINER_EXTENDED is defined as:
I knew it was going to cause me troubles sooner or later but it seems like it was sooner. I don't know how else to work with it, should I not extend D3DXMESHCONTAINER?

Hey there, here is a good link to a site, this helped me. read it if not allready done so.
