Hi guys,

I tried to add in the keyTyped() function into the following code but it does not change the value of the string. Please advice.

import processing.opengl.*;
import geomerative.*;
RFont f;
RGroup grp;
RShape s;
float len;
float angle;
float pos;

// the error range for the tangent position and angle
float ANGLEERROR = 0.3;
float POINTERROR = 0;

float LENGTHTANGENT = 20;
// the initial text
String msg = "RShape";
String FONT = "lucon.ttf";
//the alpha value of the lines
int ALPHAVALUE = 10;
//the velocity of the calligraphy
int VELOCITY =10;
int MARGIN = 50;

void setup () {
  size(500, 500, OPENGL);
  background(255);
  frameRate(25);
  LENGTHTANGENT = LENGTHTANGENT * width/800F;

RG.init(this);
  noFill();
  stroke(0, 0, 0, 10);
  f = new RFont(FONT, 372, RFont.CENTER);
  initialize();
 
}
void draw() {
  pushMatrix();
  translate(width/2, height/2);
  //Draw very low alpha and long tangents on random points of each letters
  for (int i =0; i<grp.countElements(); i++) {
    s = (RShape)(grp.elements[i]);
    for (int j=0; j<s.countPaths();j++) {
      for (int k=0;k<VELOCITY; k++) {
        pos = random(0, 1);
        RPoint tg = s.paths[j].getTangent(pos);
        RPoint p = s.paths[j].getPoint(pos);
        p.x = p.x +random(-POINTERROR, POINTERROR);
        p.y = p.y +random(-POINTERROR, POINTERROR);
        len = random(-LENGTHTANGENT, LENGTHTANGENT);
        angle = atan2(tg.y, tg.x) + random(-ANGLEERROR, ANGLEERROR);
        bezier(p.x, p.y, 10, 10, 90, 90, 15, 80);
      }
    }
  }
  popMatrix();
}
void initialize() {
  grp = f.toGroup(msg);
  grp.centerIn(g, MARGIN, 1, 1);
  background(255);
}

void keyTyped() {
  if(key==ENTER) {
    msg="";
  }
  else {
    msg+=key;
   initialize();
  }
}
