Looks alot cleaner than what i did rn.
Btw does it work for double zoom?

[NexSqaud]

This does not work correctly when using a single scope.

[PUREHAX]

Where do I need to put it ? :)

[NexSqaud]

misc.h and call it from paintTraverse hook like this

//some stuff before this
Misc::spectatorList();
Misc::drawFov();
//and after this

and put

bool drawFOV{false};

in Misc config struct and put

ImGui::Checkbox("Draw Aimbot FOV", &config.misc.drawFOV);

in GUI.cpp near of

ImGui::Checkbox("Watermark", &config.misc.watermark);

in config.cpp put

if (miscJson.isMember("Draw FOV")) misc.drawFOV = miscJson["Draw Fov"].asBool();

near of

if (miscJson.isMember("Watermark")) misc.watermark = miscJson["Watermark"].asBool();

and final put

miscJson["Draw FOV"] = misc.drawFOV;

near of

miscJson["Watermark"] = misc.watermark;

[noteffex]

It doesnt draw accurately though like the fov is 2x less than what is drawn.

[NexSqaud]

update:
hooks.cpp

static void __stdcall overrideView(ViewSetup* setup) noexcept
{
    if (interfaces.engine->isInGame()
        && !interfaces.entityList->getEntity(interfaces.engine->getLocalPlayer())->getProperty<bool>("m_bIsScoped"))
        setup->fov += config.visuals.fov;
    setup->farZ += config.visuals.farZ * 10;
    Misc::actualFov = setup->fov;
    hooks.clientMode.callOriginal<void, ViewSetup*>(18, setup);
}

misc.h

static float actualFov = 0.0f;

    constexpr void drawFov() noexcept
    {
        if (config.misc.drawFOV && interfaces.engine->isInGame()) {
            auto local = interfaces.entityList->getEntity(interfaces.engine->getLocalPlayer());
            if (!local || !local->isAlive()) return;
            if (!local->getActiveWeapon()) return;
            int weaponId = getWeaponIndex(local->getActiveWeapon()->getProperty<WeaponId>("m_iItemDefinitionIndex"));
            if (!config.aimbot[weaponId].enabled) weaponId = 0;
            if (!config.aimbot[weaponId].enabled) return;
            auto screenSize = interfaces.surface->getScreenSize();
            if (config.aimbot[weaponId].silent) interfaces.surface->setDrawColor(255, 10, 10, 255);
            else interfaces.surface->setDrawColor(10, 255, 10, 255);
            float radius = std::tan(DEG2RAD(config.aimbot[weaponId].fov) / 2.f) / std::tan(DEG2RAD(actualFov) / 2.f) * screenSize.first;
            interfaces.surface->drawOutlinedCircle(screenSize.first / 2, screenSize.second / 2, radius, 100);
        }
    }

now this should be works normally with scopes
Edit:Updated again.
Edit2: Tested - now works correctry with 1x scope and 2x scope

Thank you for this nice tutorial but I get some errors :( like
Error Code C2027

I've basically did everything right I guess

[PUREHAX]

And is that on purpose ?
" miscJson["Draw FOV"] = misc.watermark; " and not " miscJson["Draw FOV"] = misc.drawFOV; "

[NexSqaud]

oops, corrected everything

[PUREHAX]

I have 15 Errors with the surface :D

[NexSqaud]

🤔 can you show errors?

[PUREHAX]

Yeah but they're german :D

[NexSqaud]

add this in include section

#include "../SDK/Surface.h"

[PUREHAX]

Very nice, Thank you <3

[Piterxyz]

element class "Config :: Misc" does not have the "drawFOV" component

[Piterxyz]

Ok nvm.

Maybe there's a piece of code missing?

I'm sorry, I need glasses.

[NexSqaud]

Using a lambda expressions instead of defines

constexpr void drawFov() noexcept
    {
        if (config.misc.drawFOV && interfaces.engine->isInGame()) {
            auto local = interfaces.entityList->getEntity(interfaces.engine->getLocalPlayer());
            if (!local || !local->isAlive()) return;
            if (!local->getActiveWeapon()) return;
            int weaponId = getWeaponIndex(local->getActiveWeapon()->getProperty<WeaponId>("m_iItemDefinitionIndex"));
            if (!config.aimbot[weaponId].enabled) weaponId = 0;
            if (!config.aimbot[weaponId].enabled) return;
            auto screenSize = interfaces.surface->getScreenSize();
            if (config.aimbot[weaponId].silent) interfaces.surface->setDrawColor(255, 10, 10, 255);
            else interfaces.surface->setDrawColor(10, 255, 10, 255);
            float radius = std::tan(degreesToRadians(config.aimbot[weaponId].fov) / 2.f) / std::tan(degreesToRadians(actualFov) / 2.f) * screenSize.first;
            interfaces.surface->drawOutlinedCircle(screenSize.first / 2, screenSize.second / 2, radius, 100);
        }
    }

[xAkiraMiura]

could you make a pull request for it?

[newcommerdontblame]

pls make clear pr for this

[memsenpai]

@NexSqaud
without any errors but no fov is draw on the screen
i debug it and found code run to line drawOutlinedCircle wihtout any errors
