Problem with D3DXSprite functions...

Recommended Posts

I have been trying to get the D3DXSprite functions to work, so I can draw some simple 2D things on top of my 3D scene. I am doing it like so:
  
//begin 

Begin();

//draw the stuff using Draw()


/stop 
End();
  
It gives me 3 errors (one for each D3DXSprite function I use). It doesn''t seem to recognize those 3 functions. Do I need to do something like:
  
something->Begin();
  
?

Yes you do.
Assuming your sprite is called mySprite the calls would be

mySprite->Begin();
mySprite->Draw (/* Parameters */ );
mySprite->End();

Nope, I still can''t get it working. I am doing it like:
  
//begin drawing

lpd3dxsprite->Begin();

Where lpd3dxsprite is declared like:
  
LPD3DXSPRITE* lpd3dxsprite;

What am I doing wrong? (I can post the whole thing if you want)

Actually, you don''t have to call ID3DXSprite::Begin or ID3DXSprite::End (as per MS DX SDK docs), as the interface will call those for you if you''re attempting to draw.

If you''re getting compiler errors, make sure you have included d3dx8.h and d3dx8.lib with your project, then declare, create, and use:

  
#include "d3d8.h"
#include "d3dx8.h"

ID3DXSprite *Sprite;

// Assuming pD3DDevice = pre-initialized device object

D3DXCreateSprite(pD3DDevice, &Sprite);

pD3DDevice->BeginScene();
Sprite->Draw(......);
pD3DDevice->EndScene();

Sprite->Release();

LPD3DXSPRITE* lpd3dxsprite;



If you''re putting that in it, there''s your problem. It should either be ID3DXSprite* lpd3dxsprite; or LPD3DXSPRITE lpd3dxsprite; .
