Why the text file shows messy date saved by output.println

Hill

I try to used output.println to save data (which from println) in a text file, but the data in the output text file is unreadable. I hope some friends can help me solve this problem.

Here is my code:

PrintWriter output;

float x,y,e;
int plate_width=50, plate_height=50;
boolean UP=true;
boolean RIGHT=true;

void setup(){
  size(100,100);
  x=40;
  y=40;
  output = createWriter("gcode.doc");
}

void draw(){
  if (UP) {
  y=y+0.2;
} else {
  y=y-0.2;
}
  
 if (y>=plate_height) {
  x=x+0.2;
  UP=false;
  
 }
 
 if (y<=40) {
   UP=true;
   x=x+0.2;
 }
 
 if (x>plate_width) {
   stop();
 }
 
 String[] gcode=new String[7];

gcode[0]="G1";

gcode[1]="X";
gcode[2]=str(x);
gcode[3]="Y";
gcode[4]=str(y);
gcode[5]="E";
gcode[6]=str(e);

String[] str=new String[4];
str[0]=gcode[0];
str[1]=gcode[1]+gcode[2];
str[2]=gcode[3]+gcode[4];
str[3]=gcode[5]+gcode[6];
e=e+0.04488;


str=append(str,"");

println(str);

output.println(str);
}

If you just wanna output some String[], why not saveStrings()? :-?

Yes, i did try saveStrings(), but it didn't work. I don't know why, so i try output.println

I tried saveStrings, and it only shows this data, that is not what i want.

I think it's because str is an array

println converts it to string, output.println doesn't

  str=(String[])append(str, "");

  //  println(str);

  String str2 = join(str, ' ');  
  println(str2);

  output.println(str2);
}

Chrisir, thank u very much! u r genius!

I can't see your screenshots, but I'd bet what you want is some ".csv" or ".tsv", is it?

You may try out Table class: https://processing.org/reference/Table.html

Then use saveTable() (along w/ dataPath() if you wish) in order to get a proper "output":

GoToLoop, that is look like a good idea! i will try to learn it! Thank u very much!
