Well, this is not a question about how to split a text in 2 halfs because I can already do that. But actually exactly this is what I want to avoid
.
I have written a class to handle a texture font but its print method just shows half the text.
The class uses a texture which contains 16 * 16 letters which are 16 * 16 in size. They are the same order as in the ASCII code (but starting with 32) and I have 2 character sets per texture which makes it 256 characters and 128 characters per set.
So this is the code for printing:
void CTextureFont:rint(int iX, int iY, D3DCOLOR Color, int iCharacterSet, LPSTR strFormat, ...) {
char strText[1024];
int iCurrentPosition = 0;
int iLastX = iX;
float fX = 0.0f;
float fY = 0.0f;
va_list Arguments;
CMaterial Material;
LPVERTEX2D pFontVertices = NULL;
VERTEX2D LetterVertices[4];
if(iCharacterSet > 1) {
iCharacterSet = 1;
}
va_start(Arguments, strFormat);
vsprintf(strText, strFormat, Arguments);
va_end(Arguments);
pFontVertices = new VERTEX2D[strlen(strText) * 4];
ZeroMemory(pFontVertices, sizeof(VERTEX2D) * strlen(strText) * 4);
m_pVertexBuffer->ShutDown();
m_pVertexBuffer->Init(m_pGraphics, strlen(strText) * 4, VERTEX_2D, sizeof(VERTEX2D), D3DUSAGE_WRITEONLY);
for(int i = 0; i < strlen(strText); i++) {
fX = float(strText - 32 + (128 * iCharacterSet));
fY = float(strText - 32 + (128 * iCharacterSet));
fX = (Round(fX) % 16) / 16.0f;
fY = floorf(fY / 16.0f) / 16.0f;
//Links Unten
LetterVertices[0].color = Color;
LetterVertices[0].rhw = 1.0f;
LetterVertices[0].tu = fX;
LetterVertices[0].tv = fY + m_fLetterHeight;
LetterVertices[0].x = iX;
LetterVertices[0].y = iY + 16;
LetterVertices[0].z = 0.0f;
//Links Oben
LetterVertices[1].color = Color;
LetterVertices[1].rhw = 1.0f;
LetterVertices[1].tu = fX;
LetterVertices[1].tv = fY;
LetterVertices[1].x = iX;
LetterVertices[1].y = iY;
LetterVertices[1].z = 0.0f;
//Rechts Unten
LetterVertices[2].color = Color;
LetterVertices[2].rhw = 1.0f;
LetterVertices[2].tu = fX + m_fLetterWidth;
LetterVertices[2].tv = fY + m_fLetterHeight;
LetterVertices[2].x = iX + 16;
LetterVertices[2].y = iY + 16;
LetterVertices[2].z = 0.0f;
//Rechts Oben
LetterVertices[3].color = Color;
LetterVertices[3].rhw = 1.0f;
LetterVertices[3].tu = fX + m_fLetterWidth;
LetterVertices[3].tv = fY;
LetterVertices[3].x = iX + 16;
LetterVertices[3].y = iY;
LetterVertices[3].z = 0.0f;
memcpy(&pFontVertices[iCurrentPosition], LetterVertices, sizeof(VERTEX2D) * 4);
iCurrentPosition += 4;
iX += 16;
}
m_pVertexBuffer->Set(0, 4 * strlen(strText), pFontVertices);
m_pGraphics->SetTexture(0, m_pTexture);
m_pGraphics->SetMaterial(&Material);
m_pGraphics->SetRenderState(D3DRS_ZENABLE, FALSE);
m_pVertexBuffer->Render(0, 2 * strlen(strText), D3DPT_TRIANGLESTRIP);
m_pGraphics->SetRenderState(D3DRS_ZENABLE, TRUE);
m_pGraphics->GetDevice()->SetTexture(0, NULL);
SAFE_DELETEV(pFontVertices);
}
</pre>
The LetterWidth variables are always (1 / 16).
So why do I get "Hi" when I tell the function to write "Hiho" ? </i>
