[Tutorial] D3D Crosshairs

D3D Crosshairs

Ive seen the same basic/boring crosshair in public hacks and not many threads on how to do crosshairs.
So i thought id share how to create different styles.
Many of you may already know how to do this im just helping out the noobs.
If you don't understand something just post and i will try and help.
Enjoy

Globals:(Top of Code)

#define PI 3.14159265//Defining what PI is. PI is a Circle 
int CenterX = GetSystemMetrics( 0 ) / 2-1;//Gets screen X resolution then cutting it in half to get the center.
int CenterY = GetSystemMetrics( 1 ) / 2-1;//Gets screen Y resolution then cutting it in half to get the center.
LPDIRECT3DDEVICE9 pDevice;
ID3DXLine *pLine;

Basic Crosshair:

Notes:
When you see "CenterX-15" it means CenterX Minus 15 pixels.

//FillRGB(XPosition,YPosition,Width,Height,Color);
Function:
void FillRGB( int x, int y, int w, int h, D3DCOLOR color, IDirect3DDevice9* pDevice )
{
	D3DRECT rec = { x, y, x + w, y + h };
	pDevice->Clear( 1, &rec, D3DCLEAR_TARGET, color, 0, 0 );
}
Drawing it:
FillRGB(CenterX-15, CenterY, 30, 1,Red,pDevice);//Diagonal line
FillRGB(CenterX, CenterY-15, 1, 30,Red,pDevice);//Vertical line

Circle Crosshair:
[IMG]https://i238.photobucke*****m/albums/ff101/wes0001/1.jpg[/IMG]

//DrawCircle(XPosition,YPosition,Radius,numSides,Color);
Function:
void DrawCircle(int X, int Y, int radius, int numSides, DWORD Color) 
{ 

    D3DXVECTOR2 Line[128]; 
    float Step = PI * 2.0 / numSides; 
    int Count = 0; 
    for (float a=0; a < PI*2.0; a += Step) 
    { 
        float X1 = radius * cos(a) + X; 
        float Y1 = radius * sin(a) + Y; 
        float X2 = radius * cos(a+Step) + X; 
        float Y2 = radius * sin(a+Step) + Y; 
        Line[Count].x = X1; 
        Line[Count].y = Y1; 
        Line[Count+1].x = X2; 
        Line[Count+1].y = Y2; 
        Count += 2; 
    } 
    pLine->Begin(); 
    pLine->Draw(Line,Count,Color); 
    pLine->End(); 
}
Drawing it:
DrawCircle(CenterX,CenterY,8,8,Red);

Dot:

Notes:
If you adjust the size you will have to adjust the position to suit.
Example:
DrawPoint(CenterX-10,CenterY-10, 10, 10, Green);
The size is now 10 so i -10 off the XY position to suit.

//DrawPoint(XPosition,YPosition,Width,Height,Color);
Function:
void DrawPoint(int x, int y, int w, int h, DWORD color)
{
    FillRGB((int)x, (int)y, (int)w, (int)h, color);

} 
Drawing it:
DrawPoint(CenterX-1,CenterY-1, 1, 1, Green);

Cross Crosshair:

Notes:
XPosStart YPosStart starts the line and then XPosFinish YPosFinish is where the line will be drawn too.

//DrawLine(XPosStart,YPosStart,XPosFinish,YPosFinish,Width,Color);
Function:
void DrawLine(float x, float y, float x2, float y2, float width, DWORD color)
{
    D3DXVECTOR2 vLine[2];
    pLine->SetWidth( width );
    pLine->SetAntialias( false );
    pLine->SetGLLines( true );
    vLine[0].x = x;
    vLine[0].y = y;
    vLine[1].x = x2;
    vLine[1].y = y2;
    pLine->Begin();
    pLine->Draw( vLine, 2, color );
    pLine->End();
}
Drawing it:
DrawLine(CenterX+10,CenterY+10,CenterX-10,CenterY-10,1,Red);
DrawLine(CenterX-10,CenterY+10,CenterX+10,CenterY-10,1,Red);

Now that we have the main ones you can start merging them and making your own ones.
You have all the functions so ill just give your a picture and the drawing code.

Nice.
It's nice to see a crosshair tut.

[ac1d_buRn]

Looks good.

[Mr.Magicman]

Good tutorial but explain to the unknowing what you are doing instead of just supplying code...

Like tell them what GetSystemMetrics realy do its just a tip

[wassup40]

Wow amazing tut thank's dude.

[Jàzzà_]

Great tut interesting...

[freedompeace]

They can Google it. It's not that hard - it's actually incredibly easy D:

[seeplusplus]

I was going to call you a leecher, but then I saw the credits. Great post!

[Sydney]

Some fails in there.Its at the wrong pos. And there are many pDevice errors.

[inliner]

wow thanks this tut looks great maybe ill add some new crosshairs to my hack

[Stephen]

Now, /me doesnt have to write it out

[Amatowarrior]

Finally! A tutorial for this! Thank you!

[UGodly]

very nice tut will try it on my other hack

[dontcrymore15]

Wo0w Thank Rusty, Good JOB::::!!! :@

[[MPGH]Disturbed]

Not really a tutorial, more like source code.

Tutorial for people who know what they are doing.
