You can't detect the key G.

But another key, for example H:

PHP код:

//Under OnPlayerKeyStateChange
if(newkeys & KEY_CTRL_BACK) Enter_Hydra(playerid);
//Outside any other callback
stock Enter_Hydra(playerid)
{
    new veh = GetHydraInRange(playerid);
    if(!veh) return 0;
    switch(IsHydraSeatFree(veh))
    {
        case true: PutPlayerInVehicle(playerid,veh,1);
    }
    return 1;
}
stock GetHydraInRange(playerid)
{
    for(new i,l=GetVehiclePoolSize()+1,Float:p[3]; i<l; i++)
    {
        if(GetVehicleModel(i) != 520) continue;
        GetVehiclePos(i,p[0],p[1],p[2]);
        if(IsPlayerInRangeOfPoint(playerid,6.5,p[0],p[1],p[2])) return i;
    }
    return 0;
}
stock IsHydraSeatFree(veh)
{
    for(new i,l=GetPlayerPoolSize()+1; i<l; i++)
    {
        if(GetPlayerVehicleID(i) != veh) continue;
        if(GetPlayerVehicleSeat(i) == 1) return 0;
    }
    return 1;
}
