Sprite problem
Author
Heres my error:
error C2660: 'ID3DXSprite::Begin' : function does not take 0 arguments
err according to MSDN:
ID3DXSprite::Begin
Prepares a device for drawing sprites.
HRESULT Begin(
DWORD Flags
);
Parameters
Flags
[in] Combination of zero or more flags that describe sprite rendering options.
What am I doing wrong? :)

ID3DXSprite::Begin() takes one parameter, you're trying to call it, passing 0 parameters - E.g: pSprite->Begin();
Edit: If you want to pass 0 flags to it, you need to pass 0 for the dwFlags parameter.
Edit: If you want to pass 0 flags to it, you need to pass 0 for the dwFlags parameter.
I'm too lazy to look up the actual default flag, but typically passing it a value of 0 signifies 'no flags'. Try that.

That works, but doesn't explain why my sprite is not rendering.
Heres may class:
I can't see why this isn't working. It seems identical to many other tutorials I have seen.
Any advice welcome.

Make sure your render calls are between the DirectX device Begin() and End() calls. IE:
Device->Begin();
Sprite->Begin(0);
// Stuff
Sprite->End();
Device->End();
Device->Present();
... or something like that ... this is off the top of my head. Good luck.
Device->Begin();
Sprite->Begin(0);
// Stuff
Sprite->End();
Device->End();
Device->Present();
... or something like that ... this is off the top of my head. Good luck.
Try commenting out the matrix transformations. I believe the sprite interface takes care of setting that up for you when you pass in position, center, etc, for parameters.
