void CEsp::BacktrackHistory(IClientEntity* pEntity)
{
    //---------------------------------------SKELETON THINGS---------------------------------------//
    studiohdr_t* pStudioHdr = Interfaces::ModelInfo->GetStudiomodel(pEntity->GetModel());
    float health = pEntity->GetHealth();

    if (health > 100)
        health = 100;

    if (!pStudioHdr)
        return;
    
    Vector vParent, vChild, sParent, sChild;
//    const auto matrix = backtracking->records[player_index].boneMatrix;
    if (Menu::Window.LegitBotTab.AimbotBacktrack.GetState())
    {
            for (int i = 0; i < Interfaces::EntList->GetHighestEntityIndex(); i++)
            {
                int TeamNum = pEntity->GetTeamNum();
                player_info_t pinfo;
                if (pEntity && pEntity != hackManager.pLocal() && !pEntity->IsDormant())
                {
                    if (Menu::Window.LegitBotTab.AimbotBacktrack.GetState())
                    {
                        if (Interfaces::Engine->GetPlayerInfo(i, &pinfo) && pEntity->IsAlive())
                        {
                            for (int t = 0; t < 12; ++t)
                            {
                                Vector screenbacktrack[64][12];

                                for (int j = 0; j < pStudioHdr->numbones; j++)
                                {
                                    mstudiobone_t* pBone = pStudioHdr->GetBone(j);

                                    if (pBone && (pBone->flags & BONE_USED_BY_HITBOX) && (pBone->parent != -1))
                                    {
                                        vChild = pEntity->GetBonePos(j);
                                        vParent = pEntity->GetBonePos(pBone->parent);

                                        if (Render::WorldToScreen(vParent, sParent) && Render::WorldToScreen(vChild, sChild))
                                        {
                                            Render::Line(sParent[0], sParent[1], sChild[0], sChild[1], Color(250, 250, 250, 255));
                                        }

                                    }
                                }
                            }

                        }
                    }
