String sentence = "This is a sentence";
String[] save;
String[] load;

void setup(){
  size(displayWidth, displayHeight);
  background(0);
  fill(0,0,255);
  textAlign(CENTER);
  textSize(64);

  save = split(sentence, " ");
  text(save[0], width/2, height*0.2);
  text(save[1], width/2, height*0.4);
  saveStrings("strings.txt", save);
  load = loadStrings("strings.txt");
  text(load[2], width/2, height*0.6);
  text(load[3], width/2, height*0.8);
}

This should output the words "This is a sentence" down the middle of the window. However it returns an error saying that the index called is longer than the string length, for text(load[2], width/2, height*0.6);. Meaning the the variable "load" didn't load in anything from "strings.txt". I know this is an issue with saveStrings() because when I open strings.txt and put in 1, 2, 3, 4 on different lines, the code ouputs "This is 3 4" down the middle. Also when I check strings.txt it doesn't have the String[] saved. I've tried putting strings.txt in different locations but it still doesn't work.

basically the problem is that when i try to save a xml file with the function "saveXML()" it changes some chars, for example, if a variable has the char "&" it gets changed with "& amp;".

Any idea on what is happening?

(Mod edit, broke the html entity so it's visible)

I recently made an android game and I want to be able to save a high score. I've tried looking at other discussions on this forum but I couldn't find anything relevant to Android mode. Most of it was to do with Java mode. If it's relevant, I only need to save a single number at any one point in time.

Here are the steps that I believe I need to take in order to create a high score:

1. Upon opening the app, check if a highscore.txt file is saved and if so, load it. Otherwise, create a new highscore.txt file with its only content being '0'.

2. Upon 'death', aka playing and losing the game, compare the number in the highscore.txt file against the current score.

3. Overwrite the highscore.txt file with the higher score.

My score is an int value named currentScore.

I've tried tinkering around to implement it myself, but I don't know where to start with permissions and everything.

Any help would be greatly appreciated! Have a nice day :)

Can I save it without the added .txt?

Thanks

and another thing: how do i load the text in txt into the document, by clicking on another button :)

thanks in advance :)

This makes my program take ages to run. I added a setRowCount(); line to my code but this did not remedy my issue, it gave me an empty table. Here is my code with the added line:

// stuff is a large array of values > 1 million
t = new Table();
t.setRowCount(10000000);  
t.addColumn("Stuff"); 
for( int i = o; i < stuff.length; i++) 
    {  
    TableRow newRow = t.addRow(); 
    newRow.setFloat("Stuff", stuff[i]);
    } 
saveTable(t, "data.csv");

What I am trying to do is then take that array and save it as a file, like json or txt file, that I can load at a later date and then use the numbers stored in the array. I have tried using saveJSON() and saveText, as well as some others, but I cannot get it to work. So how do I save an array as a type of file that I can load at a later time. Below is my code:

var saved = [];

function setup(){
  createCanvas(950, 700);
  var saver = createButton("Save");
  saver.size(width / 11, width / 11);
  saver.position(instruments[0].x - (instruments[0].r * 4), instruments[223].y + (instruments[0].r / 2));
  saver.mousePressed(Saves);
    }

    function Saves() {
  for (var i = 0; i < instruments.length; i++) {
    if (instruments[i].active === true) {
      append(saved, i);
    }
  }

This is how I calculated the translation: trans += getStriplength() * deltascale getStriplength returns the length of the whole strip of objects while deltascale is the amount that is reduced each time when the mouse scrolls. Its default value is 0.2, which means the objects will be either 1.02 times bigger or 0.98 times smaller than the original. Therefore I am getting the difference of the lengths of the strip before and after, and adding it to the offset. However as I mentioned before it doesn't work the more you zoom in/out. Any help will be appreciated!

Thank you!

the easiest it will cycle through "for", but as a change in the cycle variable name Glabel?

for(int i=0; i<+2;i++) { ['label'+і].setText(reader.readLine());} So not working

It only works when I uncomment line 27 but than it doesn't check if score is bigger than the highScore

String highScore="";

String highScore="";

int score;

void setup()
{

}

void draw()
{
  String lines[] = loadStrings("highScore.txt");
  println("there are " + lines.length + " lines");
  for (int i = 0 ; i < lines.length; i++)
  {
    println(lines[i]);
  }

  println(score);
}

  }
}

Also i only want to print the first 10 lines of the txt file in the console when i press the ENTER key. But if the file contains only 3 lines i get an ArrayIndexOutOfBoundsException. How do i stop this from happening?

PrintWriter history;

void setup() {
  size(700, 350);
  history = createWriter("history.txt");
}

void draw() {
}

void keyPressed() {
  if ((key=='1')) { 
    history.println("User pressed 1");
  }

  if ((key=='2')) { 
    history.println("User pressed 2");
  }

  if ((key == ENTER)) {
    history.flush(); 
    history.close();
    String[] history = loadStrings("history.txt");
    for (int i = 0; i <= 9; i++) { //only print first 10 lines
        printArray("[" + i + "] " + history[i]);

  }

I am trying to write data to a text file with multiple characters per line but saveStrings() isn't working for me. It acts the same as save() and gives me just one character per line.

eg: dataList = "String"; saveStrings(dataList, 'dataString.txt');

gives me a text file with:

S t r i n g

I'm currently trying to send some data from Arduino to Processing, so I can save it in a file. To be more specific, there are two variables (frequency of a blinking LED and respective LED number) which should be saved in tabular form.

Hereby the following Processing code is used:

import processing.data.Table;
import processing.serial.*;


Serial myPort;
Table dataTable; //table to store my values.

int lf = 10;
String Arduinostring = null;
float values;

String fileName;
void setup()
{
  String portName = Serial.list()[0]; 
  myPort = new Serial(this, portName, 9600); //the port I'm using to listen to the serial port

  dataTable = new Table();
  dataTable.addColumn("id"); 


  //columns for values
  dataTable.addColumn("Data");
}

  void draw() {
    while (myPort.available() > 0) {
      Arduinostring = myPort.readStringUntil(lf);
      if (Arduinostring != null) {
          print(Arduinostring);  // Prints String
          values=float(Arduinostring);  // Converts and prints float
          println(values);
      }
    TableRow newRow = dataTable.addRow(); //add a row for this new reading
    newRow.setInt("id", dataTable.lastRowIndex());//record a unique identifier (the row's index)

    //record information. 
    newRow.setFloat("Data", values);   
    }

    saveTable(dataTable, "data/new.csv"); // save it to computer.

}

My intention here is to get my data into the table (and into my file). I managed to receive the required data (frequency, LED number), but this data isn't saved in my file. The mentioned file is created by the way and at least has the right ID for each Row.

What I simply do not understand is that he can't save it though the received data should be converted to float with the command num=float(myString), shouldn't it?

Many thanks in advance for any help!

Thank you Dimitrios

How could I save the contents of a textArea in a text file?

It worked to open normal as the example in the link below, but still managed to save not ... tried this code, but it gives error, the syntax is wrong ...

https://forum.processing.org/one/topic/textarea-using-controlp5.html

stretch code:

//String[] lines = loadStrings(textArea.getText());
//printArray(lines);

String lines = textArea.getText()
println(lines);

for (int i = 0; i <= lines.length-1; i++){
   lineSave[i] = lines[i];
}

saveStrings(split(lineSave, "\n"));

Thanks in advance for your attention.

I'm trying to create a single project in Processing to do all the things I need. Here's what I'd like to do:

1. Have a single text entry box that would allow a user to type in a set number of characters.
2. a "submit" button that would then write this text to a .txt file as part of a running string / data store
3. Upon hitting submit, another item from the string .txt file would be called up and printed to a thermal printer that I have hooked to an Arduino Uno (that has firmata loaded up).

I know how to do these things separately using HTML, PHP, and so on, and I can print to the thermal printer using Processing / Firmata. I'm just looking for insight and guidance to try and do all this in one fell swoop.

Any time and direction is greatly appreciated.

Thank you.

PS: When I check the monitor serial from Arduino, the data are there, so I believe anything here is wrong.

Thanks!!!!
