Unable to write data in a text file

File getting created successfully but data is not getting written in file.

code:-

PrintWriter output;

void setup() {
// Create a new file in the sketch directory
output = createWriter(“positions.txt”);
}

void draw() {
point(mouseX, mouseY);
output.println(mouseX + “t” + mouseY); // Write the coordinate to the file
}

void keyPressed() {
output.flush(); // Writes the remaining data to the file
output.close(); // Finishes the file
exit(); // Stops the program
}

code looks ok, did you try to use size() and save the sketch prior to using

works for me


PrintWriter output;

void setup() {
  size(333, 333); 
  // Create a new file in the sketch directory
  output = createWriter("positions.txt");
}

void draw() {
  point(mouseX, mouseY);
  if (mouseX!=0)
    output.println(mouseX + "t" + mouseY); // Write the coordinate to the file
}

void keyPressed() {
  output.flush(); // Writes the remaining data to the file
  output.close(); // Finishes the file
  exit(); // Stops the program
}
