Adventure Game Studio

Hello, everyone.  I am new to AGS and have started working on my own game.  I have always made a consistent effort to search through the manual and on the forum to find answers to my questions before I ask, and up to now, that's what I have done.  I am stumped, however, on this certain portion I have been trying to complete in my game.

I have created a GUI of a keypad.  I would like for this keypad to be able to unlock a door in the same room once a six-digit code has been entered, which is "233524".  The GUI is composed of nine buttons, which contain the numbers 1-9, and a text box, which displays the numbers that have been punched in.  My dilemma is this: I am aware that, through the keyboard, you can manually enter characters in the text box.  However, I would like to include the option of utilizing the GUI's buttons and pushing the buttons to display numbers.  I have figured this out, but whenever I push a new number, it overrides the old number that was previously in the text box.  Obviously, I want to script this so that pressing buttons on the keypad will be the same as manually typing in the code on the keyboard.  This is the code that I have regarding the buttons so far, when the GUI is visible:

function Keypad1_OnClick(GUIControl *control, MouseButton button)
{
Keypadscreen.Text="1";
}

function Keypad2_OnClick(GUIControl *control, MouseButton button)
{
Keypadscreen.Text="2";
}

function Keypad3_OnClick(GUIControl *control, MouseButton button)
{
Keypadscreen.Text="3";
}

function Keypad4_OnClick(GUIControl *control, MouseButton button)
{
Keypadscreen.Text="4";
}

function Keypad5_OnClick(GUIControl *control, MouseButton button)
{
Keypadscreen.Text="5";
}

function Keypad6_OnClick(GUIControl *control, MouseButton button)
{
Keypadscreen.Text="6";
}

function Keypad7_OnClick(GUIControl *control, MouseButton button)
{
Keypadscreen.Text="7";
}

function Keypad8_OnClick(GUIControl *control, MouseButton button)
{
Keypadscreen.Text="8";
}

function Keypad9_OnClick(GUIControl *control, MouseButton button)
{
Keypadscreen.Text="9";
}

I have searched countless times in the manual and on the forum attempting to solve this.  I do apologize if this question has already been answered in a previous thread.  Again, I have been working on this game for a couple of months and have always looked up a question I have had.  This specific problem has just stumped me, though.  Any help would be greatly appreciated, and if I have been unclear in any way, please let me know and I'll try to elaborate.  Thanks!

The reason that it's replacing the input is because that script is replacing the content of that String rather than adding on to it. I don't have the manual handy, but you're going to need to write something to this effect:

function Keypad1_OnClick(GUIControl *control, MouseButton button)
{
Keypadscreen.Text = Keypadscreen.Text + "1";
}

If this doesn't work, the + sign is the problem. Look through the manual to see if you can find the operator that allows you to join Strings together.

Keypadscreen.Text = Keypadscreen.Text.AppendChar('1');

Additionally, you'll probably want the leftmost digit to disappear if the player enters a seventh digit, correct?

Plus, the whole OnClick business can be simplified greatly:
Every GUIControl has a unique ID, starting at 0. If you create/edit the buttons so that their label is the same as their ID, you'll only need one OnClick to cover all of them:

function Keypad_OnClick(GUIControl *control, MouseButton button) {
  if (button != eMouseLeft) return;  // only react to left-clicks
  String s = Keypadscreen.Text;
  if (s.length == 6) s = s.Substring(1, 5);  // cut off leftmost digit
  Keypadscreen.Text = String.Format("%s%d", s, control.ID);      // add the button's ID to the display

  if (Keypadscreen.Text == "233524") CallRoomScript(1);  // unlock door
}
Now enter "Keypad_OnClick" into each button's OnClick field.

You might want to use a label rather than a textbox to display the code, btw, to prevent the player from typing into it.

In the room script, add this function:
function on_call(int p) {
  if (p==1) {
    // this gets called by   CallRoomScript(1);
    // show animation of opening door, etc.
  }
}

Thanks so much.  I appreciate all of the help.  It answered my question, but unfortunately, more things came up as I was editing around with things.  I'll put those aside for now to see if I can work them out on my own.  Again, thank you!  I will mark this thread as solved.

You'll have to edit the subject line of your first post in order to put "solved" in the topic list.

Ha ha, my mistake.  Thanks for catching that.
