I just move to 2.0b7 right now. I coded a sketch a few days ago in which a java method: getID() is used and the sketch was workable but now it can not work in 2.0b7.

Just want to know which java class should I import to make the code work?

Many thanks:)

Processing installation address is D:\processing-2.0b3, when access proclipsing in eclipse to start new sketch, I got a alarm as follows:

D:\processing-2.0b3\ does not contain the processing libs.

Perhaps some update need to be done with proclipsing to get up with new structure of folders and files in processing 2.0.

Hi, does some one kindly introduce sample processing sketch that running on android smart phone to control arduino via bluetooth module, very few topic can be found in processing forum. thx a lot.

Hi guys,

I just encounted a problem with text display in using both 0194 and 0195 versions. With the same sketch as follows, I found characters rendered in processing 1.21 look very clean and smooth, but in both 0194 and 0195, the characters displayed with very rough and blur edge. Not sure if it's a bug, does anyone have the same experience with me?

1. PFont font;
3. void setup(){
     size(600,400);
     font=createFont("Andalus",16,true);
     smooth();
   }
5. void draw(){
     background(255);
     fill(0);
     textFont(font,60);
     textAlign(CENTER,CENTER);
     text("General Discussion",width/2,height/2);
   }

I need generate a PDF file with some chinese chars, the main structure of my code likes that:

1. import processing.pdf.*;
   PFont myFont=createFont("微软雅黑",24,true);//微软雅黑 is the name of a chinese font.
   boolean recordPDF = false;
2. void setup(){
     size(640,480);
     smooth();
   }
3. void draw(){
     background(255);
     fill(0);
     textFont(myFont,48);
     textAlign(CENTER,CENTER);
     text("显示控制窗外框design",width/2,height/2);//to display both chinese and english chars.
   }
4. void keyReleased() {
     if (key =='r' || key =='R') {
       if (recordPDF == false) {
         beginRecord(PDF, timestamp()+".pdf");
         println("recording started");
         recordPDF = true;
       }
     }
     else if (key == 'e' || key =='E') {
       if (recordPDF) {
         println("recording stopped");
         endRecord();
         recordPDF = false;
       }
     }
   }
5. String timestamp() {
     Calendar now = Calendar.getInstance();
     return String.format("%1$ty%1$tm%1$td_%1$tH%1$tM%1$tS", now);
   }

Both chinese and english chars display correctly in the sketch window, but only english chars can be found in the final output PDF file, all the chinese chars lost.

So anyone can help me? thx a lot.

Hi, I worked for few days to make this possible: press the mouse to draw a freehand line, when mouseReleased, the freehand line creep forward like a worm. I wrote part of the code as follows, but now I cannot go any more front.

1. ArrayList mouseMove;
   PFont font=createFont("TrueFrutigerLight",24,true);
2. void setup() {
     size(600,400);
     smooth();
     mouseMove=new ArrayList();
   }
3. void draw() {
     background(255);
     for(int i=0;i<mouseMove.size();i++) {
       DrawLine myLine=(DrawLine)mouseMove.get(i);
       myLine.dLine();
     }
     if (mousePressed == true) {
       mouseMove.add(new DrawLine(mouseX,mouseY,pmouseX,pmouseY));
     }
     fill(0);
     textFont(font);
     textAlign(CENTER);
     text(mouseMove.size(),width/2,30);
   }
4. /*
   void mouseReleased(){
    for(int j=mouseMove.size()-1;j>0;j--){
    mouseMove.remove(j);
    }
    }*/
5. class DrawLine {
     float x1;
     float y1;
     float x2;
     float y2;
6.   DrawLine(float a,float b,float c,float d) {
       x1=a;
       y1=b;
       x2=c;
       y2=d;
     }
7.   void dLine() {
       stroke(150);
       strokeWeight(2);
       line(x1,y1,x2,y2);
     }
   }
   

how can I get mouse trace position coordinate values from ArrayList? Or you will have better ideas to achieve that.

something wrong with my system, cause version 0186 processing can not run with the information: Launch4j: An error occurred while starting the application. But Processing-1.1 is ok with my system: win7+java6u20. any help welcome.
