Draw Circle

**Donor** · 06-24-2013

I decided to make myself a "cool" crosshair.)))))
and for one to learn to draw in D3D.
I drawed this.

Code:

void CrossHair1(LPDIRECT3DDEVICE9 pDevice, int size, int strong,  D3DCOLOR xcolor)
{
	int iCenterX = GetSystemMetrics( 0 ) / 2;
	int iCenterY = GetSystemMetrics( 1 ) / 2;

	if( iCenterX < 20 && iCenterY < 20 )
	{
		iCenterX = ( GetSystemMetrics( 1 ) / 2 );
		iCenterY = ( GetSystemMetrics( 0 ) / 2 );
	}

	D3DRECT rec1 = { iCenterX- size, iCenterY - 1, iCenterX+ size -1 , iCenterY+ strong };
	D3DRECT rec2 = { iCenterX -1, iCenterY- size, iCenterX+ strong ,iCenterY+ size -1 };
	pDevice->Clear(1, &rec1, D3DCLEAR_TARGET, xcolor, 1000,  0);
	pDevice->Clear(1, &rec2, D3DCLEAR_TARGET, xcolor, 100,  0);
}


void CrossHair2(LPDIRECT3DDEVICE9 pDevice, int size, int strong,  D3DCOLOR xcolor)
{
	int iCenterX = GetSystemMetrics( 0 ) / 2;
	int iCenterY = GetSystemMetrics( 1 ) / 2;

	if( iCenterX < 20 && iCenterY < 20 )
	{
		iCenterX = ( GetSystemMetrics( 1 ) / 2 );
		iCenterY = ( GetSystemMetrics( 0 ) / 2 );
	}
	
	D3DRECT rec5 = {iCenterX-3, iCenterY - 2, iCenterX+ 3-1, iCenterY+1};
    D3DRECT rec6 = {iCenterX - 2, iCenterY-3, iCenterX+ 1,iCenterY+3-1}; 
    pDevice->Clear( 1, &rec5, D3DCLEAR_TARGET, xcolor, 0, 0 );
    pDevice->Clear( 1, &rec6, D3DCLEAR_TARGET, xcolor, 0, 0 );
}

Works fine in the game.

But when I draw this:

Code:

void CrossHair4(int x, int y, LPDIRECT3DDEVICE9 pDevice)
{
        DrawCircle(x, y, 8, 8, Red);//Circle
	FillRGB(x-17, y, 10, 1,Red,pDevice);//Left line
	FillRGB(x+9, y, 10, 1,Red,pDevice); // Right line
	FillRGB(x, y - 17, 1, 10,Red,pDevice);//Top line
	FillRGB(x, y + 9, 1, 10,Red,pDevice);//Bottom line
}

My Game is crashed. why?
I have two Hooks:
1. for menu
2. for wallhack

Code:

DWORD WINAPI Hook(LPVOID lpArgs)
{
	DWORD dwD3D9 = 0;

	while(!dwD3D9) {
		Sleep(100);
		dwD3D9 = (DWORD)GetModuleHandleA("d3d9.dll");
	}

	DWORD dwVTable[2] = { 0 };
	CreateDevice(dwVTable);

	oReset   = (tReset)  DetourCreate((PBYTE) dwVTable[0], (PBYTE) &hkReset, 5);
	oPresent = (tPresent)DetourCreate((PBYTE) dwVTable[1], (PBYTE) &hkPresent, 5);
	
	return FALSE;
}  

void D3D_Hook()
{
	

switch(GAME)
{
		case Game::CombatArms:
				{ 
					    DWORD dwVTable[2] = { 0 };
						DWORD *vtbl;
				DWORD hD3D=0;
				do {
						hD3D = (DWORD)GetModuleHandleA("d3d9.dll");
						
						Sleep(10);
				}
				while(!hD3D);
						DWORD adr = FindPattern(hD3D, 0x128000, (PBYTE)"\xC7\x06\x00\x00\x00\x00\x89\x86\x00\x00\x00\x00\x89\x86", "xx????xx????xx");
						if(adr)
						{
								memcpy(&vtbl,(void *)(adr+2),4);
 
								nomar = vtbl[152] + 5;
								       
										pDrawIndexedPrimitive   = (DrawIndexedPrimitive_)DetourCreate((PBYTE)(vtbl[152]),(PBYTE)MyDIP_CA,5);
										return;
						}
					}
		break;
		
		
		break;
}
}

Explain what the problem is. Please)))

Post your DrawCircle function? Then I can help better

void DrawCircle(int x, int y, int radius, int numSides, DWORD Color)
{
#define PI 3.14159265
D3DXVECTOR2 Line[128];
float Step = PI * 2.0 / numSides;
int Count = false;
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;

Dias does not draw a circle, and everything else draws the line currents are all there.
This is code from your cheat? in your cheat does not draw a circle too.
