This isn't much of a tutorial, rather some example code, but anyway. This code shows that text input in Fenix is not hard at all: with just a little piece of code, much can be achieved.

Note that this is code for Fenix versions 0.93 and up. Should the code work for other versions as well, be so kind to note this here.

[edit] Example code

Declare Function String textinput();
End

Begin

    set_fps(60,0);

    say("You typed: '" + textinput() + "'");

    Repeat
        frame;
    Until(key(_esc));

    String str;

    // clean the string
    str = "";

    // get input from the user
    // pressing enter will end the loop
    Loop

                            str+=chr(ascii);
                        end
                    end
                end
                t2++;
            end
            t++;
        else
            t = t2 = 0; // reset
        end
        last_ascii = ascii;
        frame;
    End

    // delete the text used
    delete_text(txtid);

    // return the typed string
    return str;

End

Used in example: set_fps(), say(), write_string(), substr(), chr(), declare, function, switch, ascii, fps

You'll find a nice ASCII table here.
