trying to input text
Nov 17th, 2009, 9:56pm  
I haven't coded in many years, and I'm developing a program to take input from a user and then encode it in color.  But I'm stuck at the beginning... and I'm wondering if I should use a different language (maybe vb or at worst c?). Processing is definitely different to think about than I'm used to.

I want to prompt the user to type a secret, then get the string they enter (ended by a newline) and save it as an array of chars.


why doesn't this work to get a string from a user?

char[] inputtext ;
int timeskeypressed =0;


void keyPressed(){
  inputtext[timeskeypressed] = key;
 println (inputtext[timeskeypressed++]);
}
void draw() {

}

Probably because you haven't initialized the inputtext array.
And of course, you will have to convert the array of chars to a String, but that's easy.

String input = "";

void keyPressed(){
  if( ((key>='A')&&(key<='Z')) || ((key>='a')&&(key<='z')) || ((key>='0')&&(key<='9')) ){
    input+= key;
    println( input );
  }
  if( (key==ENTER) || (key==RETURN) ) {
    println( "The user has entered the secret: '" + input + "'" );
    if (input.equals( "Passw0rd" )) {
      println( "That is the correct secret!!!" );
    } else {
      println( "That is not correct." );
    }
    input = "";
  }
}

void draw(){
}



Hope this helps.
