[Coding] ranged 2d distance for aimbots topic

ok maybe nothing new here but i wanna share the technique i use to get range of aiming from crosshair to get cloestSoldier(credits : Lowrob, smallc, ICY, others i forget)

first of all i use numpad to toggle distance so i delacre this for vkdown and vkup and declare the integral type for disttoaim

PHP Code:

---


#define KEYDOWN(vkCode) ((GetAsyncKeyState(vkCode) & 0x8000) ? true : false)
#define KEYUP(vkCode) ((GetAsyncKeyState(vkCode) & 0x8000) ? false : true)

int distToAim = 25;

then the function to get cloest soldier

PHP Code:

---


float getDistFromCrosshair(ClientPlayer *pCloestSoldier)
{
    D3DXVECTOR3 screenM;
    D3DXVECTOR3 returningVector;
    if (IsValidPtr(pCloestSoldier))
    {
        D3DXMATRIX transfo;
        DxRenderer *pDxrenderer = DxRenderer::GetInstance();
        if (IsValidPtr(pDxrenderer))
        {
            Screen *pScreen = pDxrenderer->m_pScreen;
            if (IsValidPtr(pScreen))
            {
                screenM.x = (float)pScreen->m_Width / 2;
                screenM.y = (float)pScreen->m_Height / 2;
                screenM.z = 0;

                ClientSoldierEntity *pSoldier = pCloestSoldier->m_pControlledControllable;
                if (IsValidPtr(pSoldier))
                {
                    pSoldier->GetTransform(&transfo);
                    D3DXVECTOR3 cloestSoldPos;
                    cloestSoldPos = transfo.m[3];

                    if (WorldToScreen(&cloestSoldPos))
                    {
                        returningVector.x = cloestSoldPos.x - screenM.x;
                        returningVector.y = cloestSoldPos.y - screenM.y;
                        //printf_s("X[%f]Y[%f]", returningVector.x, returningVector.y, fuck);
                        returningVector.z = 0;
                        float returndist = sqrtf((returningVector.x * returningVector.x) + (returningVector.y * returningVector.y));
                        //printf_s(" Ret[%f]\n", returndist, fuck);

                        if (returndist < distToAim)
                            return returndist;
                        
                    }

                    else
                    {
                        return 10000.0f;
                    }
                }
            }
        }
    }
    return 10000.0f;
}

this line is very important to set your size

PHP Code:

---


                        if (returndist < distToAim)
                            return returndist;

some usefull drawing functions to draw a circle

PHP Code:

---


void Draw2DCircle(float x, float y, float radius, D3DCOLOR color) // , LPDIRECT3DDEVICE9 dev
{
    const int NUMPOINTS = 24 * 2;
    const float PI = 3.14159;
    D3DTLVERTEX Circle[NUMPOINTS + 1];
    int i;
    float X;
    float Y;
    float Theta;
    float WedgeAngle; //Size of angle between two points on the circle (single wedge)
    //Precompute WedgeAngle
    WedgeAngle = (float)((2 * PI) / NUMPOINTS);
    //Set up vertices for a circle
    //Used <= in the for statement to ensure last point meets first point (closed circle)
    for (i = 0; i <= NUMPOINTS; i++)
    {
        //Calculate theta for this vertex
        Theta = i * WedgeAngle;
        //Compute X and Y locations
        X = (float)(x + radius * cos(Theta));
        Y = (float)(y - radius * sin(Theta));
        Circle[i] = CreateD3DTLVERTEX(X, Y, 0.0f, 1.0f, color, 0.0f, 0.0f);
    }
    //Now draw the circle
    pDevice->SetFVF(D3DFVF_TL);
    pDevice->SetTexture(0, NULL);
    pDevice->DrawPrimitiveUP(D3DPT_LINESTRIP, NUMPOINTS, &Circle[0], sizeof(Circle[0]));
} 





---

PHP Code:

---


void drawRangeofAim(int rom)
{
    CenterX = DxRenderer::GetInstance()->m_pScreen->m_Width / 2;
    CenterY = DxRenderer::GetInstance()->m_pScreen->m_Height / 2;

    Draw2DCircle(CenterX, CenterY, rom, D3DCOLOR_RGBA(255, 0, 0, 255));
}

finally in the rendering (in case you have an injected overlay you can do that to get the 2d range of aim get drawn in your screen

PHP Code:

---


int Render()
{
    pDevice->Clear(0, NULL, D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER, NULL, 1.0f, 0);
    pDevice->BeginScene();
    pDevice->CreateStateBlock(D3DSBT_ALL, &StateBlock);
    if (TargetWindow == GetForegroundWindow())
    {
        sprintf_s(distAimed, "current 2d aim Range[%i]", distToAim);
        DrawString(distAimed, 10, 10, 255, 0, 0, pFont);

        if (KEYDOWN(VK_NUMPAD3))
        {
            Sleep(10);
            drawRangeofAim(distToAim + 25);

            if (KEYUP(VK_NUMPAD3))
            {
                distToAim += 25;
                drawRangeofAim(distToAim);

                if (distToAim > 350)
                    distToAim = 25;
            }
        }

        if (GetKeyState(VK_NUMPAD4))
            drawRangeofAim(distToAim);
    }


    pDevice->EndScene();
    pDevice->PresentEx(0, 0, 0, 0, 0);
}
