Combination Lock Using Levers Code?

[Your Computer]

At first i was going to explain it all, but decided just to post some code:

PHP Code: (Select All)

const string[] secret_door_lever_positions =
    {"secret_door_first_lever",
     "secret_door_second_lever",
     "secret_door_third_lever"};

void OnStart ()
{
    SetEntityConnectionStateChangeCallback("lever_left", "SecretDoorLevers");
    SetEntityConnectionStateChangeCallback("lever_middle", "SecretDoorLevers");
    SetEntityConnectionStateChangeCallback("lever_right", "SecretDoorLevers");

    ClearSecretDoorLevers();
    ResetSecretDoorLevers();
}

void ClearSecretDoorLevers()
{
    SetLocalVarString(secret_door_lever_positions[0], "");
    SetLocalVarString(secret_door_lever_positions[1], "");
    SetLocalVarString(secret_door_lever_positions[2], "");
}

void ResetSecretDoorLevers()
{
    SetLeverStuckState("lever_left", 0, true);
    SetLeverStuckState("lever_middle", 0, true);
    SetLeverStuckState("lever_right", 0, true);
}

void SecretDoorLevers(string &in entity, int state)
{
    SetLeverStuckState(entity, state, false);

    for (int i = 0; i < secret_door_lever_positions.length(); ++i)
    {
        if (GetLocalVarString(secret_door_lever_positions[i]) == "")
        {
            SetLocalVarString(secret_door_lever_positions[i], entity);
            break;
        }
    }

    CheckSecretDoorLeversOrder();
}

void CheckSecretDoorLeversOrder()
{
    if (GetLocalVarString(secret_door_lever_positions[0]) == "lever_middle"
     && GetLocalVarString(secret_door_lever_positions[1]) == "lever_right"
     && GetLocalVarString(secret_door_lever_positions[2]) == "lever_left")
    {
        CompleteSecretDoorLeversPuzzle();
    }

    else if (GetLocalVarString(secret_door_lever_positions[0]) != ""
     && GetLocalVarString(secret_door_lever_positions[1]) != ""
     && GetLocalVarString(secret_door_lever_positions[2]) != "")
    {
        ClearSecretDoorLevers();
        ResetSecretDoorLevers();
    }
}

void CompleteSecretDoorLeversPuzzle()
{
    AddDebugMessage("Secret door puzzle complete!", false);
    Print("Secret door puzzle complete!");
    // Open secret door
} 


Note, you'll have to change the names of the levers to "lever_middle", "lever_left" and "lever_right". Since you didn't specify which state you want the levers to be pulled at, pulling them in either direction should work.
