HI everyone, I’m new to Processing and have been fighting my way through my first attempts at coding and now need some help.  I don’t want anybody to post the code just yet (that would be too easy and spoil then fun), any pointers/explanation as to how I go about the following, please then if I can’t do it I’ll post again.

My project is to load a text file that contains a large string of “0” and “1” (at the moment not delimited but could be if needed).  I want processing to check the first char/ and if it’s a “0” then print a blue rect, if it’s a “1” then a red rect.


I can load the file ok using loadstring and I can write the code for displaying the rect.  But I can’t seem to find any information (also through lack of programming knowledge) on how processing would read the first char,  draw rect  then read the second char draw rect, read the third char, etc, etc.

The text/dat file ( advice as to which to use please) would contain thousands of chars (hopefully) and would be processed through a database first then fed into processing

Any help will be greatly appreciated,

Thank in advance


Neill

thanks for that ,could you elaborate abit more..please..I'm using loadstring but i unsure as to what "method" refers to ?

thanks

Code:

String lines[] = loadStrings("onesandzeros.txt");
// for each line..
for (int i = 0; i < lines.length; i++) {
  // for each character in the line
  for (int j = 0; j < lines[i].length(); j++) {
    char c = lines[i].charAt(j);
    if (c == '0') {
	drawBlueRect();
    } else {
	drawRedRect();
    }
  }
} 

It works and has opened so many new doors...thank you Mr Fry for taking the time... which is oblivously  such a simple code to you, but was stumbling block for me.
