ID3DXSprite的问题……

为啥在ID3DXSprite->Begin()的时候会有问题啊？

Game.exe 中的 0x004011c0 处未处理的异常: 0xC0000005: 读取位置 0x00000000 时发生访问冲突

这究竟是什么问题啊囧……


void Render() {
    if (g_pD3DDevice->Clear(NULL, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0, 0, 0), 1.0, 0) == S_OK){
      if (SUCCEEDED(g_pD3DDevice->BeginScene())) {
            sprite->Begin(D3DXSPRITE_ALPHABLEND);
            // TODO : Add scene rendering code here.
            sprite->End();
            g_pD3DDevice->EndScene();
            g_pD3DDevice->Present(NULL, NULL, NULL, NULL);
      }
    }
}

    }
    return hr;
}

话说没有看到 sprite 的初始化 = =
hr = D3DXCreateSprite(g_pD3DDevice,  &sprite);
