How can I make a dialogue box? Like the ones in FF I-VI?

[JustVisiting]

I was wondering how could I display a message box at the bottom of the screen, preferably with "typewriter" effect, not alll the letters appearing at once. The problem is that if I use a FOR, like (not real c++ code):

Code: Select all

for (int i=0, i< textline.lenght(), i++)
{
  AddStatic text (100,600, textline[i]);
}

the engine hangs until the text is drawn, instead of drawing it letter by letter.
Does anyone have a class for this puropse?Or some advice?

I thing what you are doing is wrong for two reasons :
- 1 - you are adding multimple staticTexts to your GUI : you have to remove and redraw your text for each cycle
- 2 - there is no delay in loop cycles, and this is why the engin hangs (i think) you have to put a sleep(delay) after each addStaticText(...)

so the code should be :

Code: Select all

IGUIStaticText * mySText=NULL;
for (int i=0, i< textline.lenght(), i++) 
{ 
  if (mySText) 
     {
       mySText->remove;
       mySText=NULL;
      }
  mySText = AddStatictext (100,600, textline[0..i]); 
  usleep(1000);
} 

hope it helps
