I am trying to rotate a crosshair every time a shot is fired. Here is the rendering code:


int CHUD::RenderCrossHair()
{
	if (CBase::m_bLeftMouse)
	{
		m_bCrossrotate=true;
		CLog log;
		log.WriteMessage("Left Mouse Click");
	}
	if (m_bCrossrotate)
	{
		m_dCrossrotate+=2*M_PI/360;
		CLog log;
		log.WriteMessage("Rotation is at point %f",m_dCrossrotate);
	}
	if(m_dCrossrotate>2*M_PI)
	{
		m_dCrossrotate=0;
		m_bCrossrotate=false;
	}
D3DXMATRIX cWorld;
	CBase::m_pDevice->GetTransform(WORLD_MATRIX,&cWorld);
	D3DXMATRIX cRotate;
	
	D3DXMatrixRotationX(&cRotate,m_dCrossrotate);
	
	CBase::m_pDevice->SetTransform(WORLD_MATRIX,&cRotate);
	
	
	if (m_pDevice && m_pCrosshair && m_pCrosshairbuffer)
	{
	
	CBase::m_pDevice->SetTexture(0, m_pCrosshair);
	CBase::m_pDevice->SetStreamSource(0, m_pCrosshairbuffer, 0, sizeof(TransformedVertex_t));
	CBase::m_pDevice->SetFVF(D3DFVF_XYZRHW | D3DFVF_DIFFUSE | D3DFVF_TEX1);
	CBase::m_pDevice->DrawPrimitive(D3DPT_TRIANGLELIST, 0, 2);

	}

	CBase::m_pDevice->SetTransform(WORLD_MATRIX,&cWorld);

	return 1;
}

The problem is that it does not rotate My log tells me that my code does detect left click and does change rotation variables but that doesn't influence the crosshair. Thank you in advance, Ilya P.S.: Here is how I created the buffer


if(FAILED(CBase::m_pDevice->CreateVertexBuffer(sizeof(TransformedVertex_t)*6, D3DUSAGE_DYNAMIC,
		D3DFVF_XYZRHW | D3DFVF_DIFFUSE | D3DFVF_TEX1, D3DPOOL_DEFAULT, &m_pCrosshairbuffer, NULL))) {
		return false;
	}

D3DFVF_XYZRHW tells D3D "the vertices I'm passing for this draw call have already been transformed so you don't need to apply any transformations to them".

Thus your SetTransform() call has absolutely no effect.

For already transformed vertices (D3DFVF_XYZRHW) you'll need to transform the vertices manually.

Or alternatively use untransformed vertices (D3DFVF_XYZ), with those the SetTransform() call will be applied as expected.

hm... it stopped rendering the crosshair all together...

If you just changed your vertices to D3DFVF_XYZ then you need to transform the vertices into screen space, and change your vertex format to remove the RHW.

That's what I am trying to do:

D3DXMATRIX cWorld;	CBase::m_pDevice->GetTransform(WORLD_MATRIX,&cWorld);	D3DXMATRIX cScale,cTranslate,cRotate,cFinal;	D3DXMatrixScaling(&cScale,10,10,10);	D3DXMatrixRotationY(&cRotate,m_dCrossrotate);	D3DXMatrixTranslation(&cTranslate,1,1,4);	cFinal=cRotate*cTranslate*cScale;	CBase::m_pDevice->SetTransform(WORLD_MATRIX,&cFinal);			if (m_pDevice && m_pCrosshair && m_pCrosshairbuffer)	{		CBase::m_pDevice->SetTexture(0, m_pCrosshair);	CBase::m_pDevice->SetStreamSource(0, m_pCrosshairbuffer, 0, sizeof(TransformedVertex_t));	CBase::m_pDevice->SetFVF(D3DFVF_XYZ | D3DFVF_DIFFUSE | D3DFVF_TEX1);	CBase::m_pDevice->DrawPrimitive(D3DPT_TRIANGLELIST, 0, 2);	}	CBase::m_pDevice->SetTransform(WORLD_MATRIX,&cWorld);

Unless you changed your TransformedVertex_t structure, then you'll be passing gibberish to D3D. Its expecting structures in the format {x,y,z,diffuse,tu,tv}, but you're passing it {x,y,z,rhw,diffuse,tu,tv}.
You also need to set up your view and projection matrices if you haven't already done so.

Changed it to

struct TransformedVertex2_t {	float x;	float y;	float z;	DWORD dDiffuse;	float u;	float v;};

But it still does not render the crosshair
