Adventure Game Studio

Hello,

I am trying to select and add text to one of 30 labels in a gui, sequentially. So if gui_label_[1-9] have text in them already, the next time the code runs, gui_label_10 is selected.

I'd love if I could do something like this:

for (int i = 1; i <= 30; i++)
{
  if (GUI_Label_[i].Text == "")
  {
    GUI_Label_[i].Text = "blah blah";
    int = 31;
  }
}

but that obviously doesn't work.

I found the 'GUIControl.GetByName' function, but that is only in AGS 3.6.1, and I am running the latest stable version. I'm happy to upgrade to 3.6.1 if that'll sort this issue, but I'm not sure how stable 3.6.1 is.

Any help is much appreciated!

It should be something like this:

function AddTextToNextLabel(GUI *mygui, String text)
{
   for (int i = 0; i < mygui.ControlCount; i++)
   {
      Label *label = mygui.Controls[i].AsLabel;
      if (label == null)
         continue; // not a label, skip

      if (label.Text == "")
      {
         label.Text = text;
         break; // stop loop here
      }
   }
}

Then you call this function
AddTextToNextLabel(gMyGuiWithLabels, "bla bla");

EDIT: argh, reading the article about "GUI.Controls" makes me cringe, because it sais that it is only for "legacy code", which is wrong.
The article should be rewritten, and have a better example.

Oh @Crimson Wizard you are a gem.

As usual, the code you responded with contained multiple different things I wasn't aware I could do. Looking at it, I was very confused at first, but I fiddled around a bit and have got it working.

Thanks once again for you time!

Right, sorry, I could explain these bits further if necessary.
Most of these things are explained in the manual, but it's not organized well in some parts, so it takes time to find what you need.

Oh, that was not a criticism. I was able to gather what I needed to understand your response by googling a bit, and I'd have bugged you again if I wan't able to figure it out. It's just that I've been doing some things which are more advanced than my actual skill/knowledge level, so I am constantly realizing that I'm doing things ass backwards. I prefer to learn this way though.
