delete[] direct3d vertex buffer memory?

sirlemonhead · 2008-07-19T16:27:16

I ->Release() my Direct3D Vertex Buffer fine, but what about the memory I allocate for it? Ie I have: #define MAX_VERTEXES 4096//9216 #define MAX_INDICES 9216 D3DTLVERTEX *mainVertex = new D3DTLVERTEX[MAX_VERTEXES]; WORD *mainIndex = new WORD[MAX_INDICES]; WORD *tempIndex = new WORD[MAX_INDICES]; as a global.. in a c++ file. now, I'm guessing I should be calling delete[] mainVertex; when it's time to close the app? I'm calling the delete operator after I do a ->Release() on the Vertex Buffer that I lock with this D3DTLVERTEX array. but doing this gives me a debug error, the nasty "_BLOCK_TYPE_IS_VALID(pHead->nBblockUse)" I'm not doing anything else with the data before that, not accidentally deleting it twice. I haven't got a deconstructor for D3DTLVERTEX so the code is pretty much D3DTLVERTEX *mainVertex = new D3DTLVERTEX[MAX_VERTEXES]; lock, fill, render with etc etc time to close the application, do ReleaseVolatileResources(); // Releases Vertex and index buffer SAFE_RELEASE(d3d.lpD3DDevice); SAFE_RELEASE(d3d.lpD3D); then I try do delete[] mainVertex but I get the _BLOCK_TYPE_IS_VALID(pHead->nBblockUse) error What am I doing wrong? do I need to even release this memory? I'm assuming yes but I always get uncertain when stuff doesn't work AND I don't think ive ever seen anyone else do it..

Ok, I got by confused by him saying that the memory will be released when I unlock. Did he mean to say it'll be released (ie freed) when I do a ->Release() on my Vertex Buffer?

Cheers guy :)

Release is not the same as free or delete! Don't confuse the terms.

Yes, the memory will be "disposed" of by DirectX when you're done with the VB and release it. Not when you Unlock the VB, but when you Release the VB.

EDIT: It probably does sound confusing - but the idea is that DirectX will take care of the memory for you, provided you Release anything you Create when you're done with it.

Are you sufficiently confused yet? [smile]

Please don't PM me with questions. Post them in the forums for everyone's benefit, and I can embarrass myself publicly.
