CS2 Triggerbot with Anti-Detection — Source 2 Implementation Guide

A triggerbot is the most subtle cheat you can use in CS2. It doesn't move your crosshair — it simply fires the instant your crosshair passes over an enemy. With proper humanization, it's virtually indistinguishable from fast reflexes.

How CS2 Triggerbot Works

CS2 stores the entity under your crosshair in a variable on the local player pawn. Reading this value tells you exactly what you're aiming at:

// m_iIDEntIndex contains the entity index under your crosshair
// -1 means no entity (looking at a wall/sky)
int crosshairEntityId = mem.Read<int>(localPawn + offsets::m_iIDEntIndex);

// If it's a valid entity, check if it's an enemy
if (crosshairEntityId > 0) {
    uintptr_t entityList = mem.Read<uintptr_t>(client + offsets::dwEntityList);
    uintptr_t entry = mem.Read<uintptr_t>(entityList + 0x8 * ((crosshairEntityId & 0x7FFF) >> 9) + 0x10);
    uintptr_t entity = mem.Read<uintptr_t>(entry + 0x78 * (crosshairEntityId & 0x1FF));

    int entityTeam = mem.Read<int>(entity + offsets::m_iTeamNum);
    int localTeam = mem.Read<int>(localPawn + offsets::m_iTeamNum);

    if (entityTeam != localTeam && entityTeam != 0) {
        // Enemy in crosshair — fire after delay
        TriggerShot();
    }
}

Humanized Delay — The Key to Staying Undetected

Real human reaction times follow a gaussian (normal) distribution, typically centered around 180-220ms. A flat random delay is detectable because it creates a uniform distribution that doesn't match human behavior.

#include <random>
#include <chrono>

class HumanizedTrigger {
    std::mt19937 rng;
    std::normal_distribution<float> delayDist;  // Gaussian distribution
    std::chrono::steady_clock::time_point targetTime;
    bool armed = false;

public:
    HumanizedTrigger()
        : rng(std::random_device{}())
        , delayDist(175.0f, 35.0f)  // mean=175ms, stddev=35ms
    {}

    // Call every frame when crosshair is on enemy
    bool ShouldFire() {
        if (!armed) {
            // Generate humanized delay
            float delayMs = delayDist(rng);
            delayMs = std::clamp(delayMs, 60.0f, 350.0f);  // Safety bounds

            targetTime = std::chrono::steady_clock::now()
                + std::chrono::milliseconds((int)delayMs);
            armed = true;
            return false;
        }

        if (std::chrono::steady_clock::now() >= targetTime) {
            armed = false;
            return true;  // Fire!
        }
        return false;
    }

    void Reset() { armed = false; }
};

// In your main loop:
HumanizedTrigger trigger;

void TriggerbotTick() {
    int crosshairEntity = mem.Read<int>(localPawn + offsets::m_iIDEntIndex);

    if (IsEnemy(crosshairEntity)) {
        if (trigger.ShouldFire()) {
            // Simulate mouse click
            mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
            Sleep(rand() % 15 + 10);  // Hold duration randomization
            mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);
        }
    } else {
        trigger.Reset();  // Reset when crosshair leaves enemy
    }
}

Weapon-Specific Settings

Different weapons need different triggerbot behavior:

Movement State Check

Don't fire while running — CS2's movement inaccuracy means you'll miss, and firing while sprinting is suspicious:

// Read player velocity
Vector3 velocity = mem.Read<Vector3>(localPawn + offsets::m_vecVelocity);
float speed = sqrt(velocity.x * velocity.x + velocity.y * velocity.y);

// Only trigger when stationary or counter-strafing
bool isStationary = speed < 5.0f;   // Nearly stopped
bool isWalking = speed < 80.0f;     // Walking speed

// For rifles: only fire when stationary
// For SMGs: can fire while walking
if (IsRifle(currentWeapon) && !isStationary) return;
if (IsSMG(currentWeapon) && !isWalking) return;
