Here is my code : f = open('text.txt', 'w') f.write("hello") f.close() noLoop()

If I have to use CreateWriter, I will, but I was wondering why the "r" works, but the "w" does not?

try { PersonalDetails = loadTable("AccountInfo.csv", "header"); // PersonalDetails is my table variable. if (PersonalDetails.getRowCount() > 0) { Registered = true; LocalScore = PersonalDetails.getRow(0).getInt("Score"); } } catch (NullPointerException e) { Table createCSV = new Table(); createCSV.addColumn("ID", Table.INT); createCSV.addColumn("Score", Table.INT); createCSV.addColumn("Name", Table.STRING); saveTable(createCSV, "data/AccountInfo.csv"); PersonalDetails = loadTable("AccountInfo.csv", "header"); if (PersonalDetails.getRowCount() > 0) { Registered = true; LocalScore = PersonalDetails.getRow(0).getInt("Score"); } }

And then in draw basically continuously save as score updates:

void draw() { if (Start) { if (Registered) { PersonalDetails.setInt(0, "Score", LocalScore); saveTable(PersonalDetails, "data/AccountInfo.csv"); } } background(255); }

As for android I continued to get the error stated above. I've tried multiple solutions to try to fix this including an InputStream and BufferedReader, this read the file perfectly fine:

BufferedReader br; String line; void readInfo() { try { InputStream is = createInput("AccountInfo.txt"); br = new BufferedReader(new InputStreamReader(is, "UTF-8")); while ((line=br.readLine())!=null) { System.out.println(line); } } catch (IOException e) { System.out.println("IOException when trying to read AccountInfo.txt:\n"+e); System.exit(0); } }

But, every approach i've taken so far to try to write the file failed. I'm assuming read works better because it will auto search the /files/ directory when not specified with a path. So far i've tried to use a BufferedWriter and PrintWriter in the same way as readInfo() above, hoping it would work, but it didn't:

PrintWriter saveInformation; BufferedWriter writer = null; void saveInfo() { try { writer = new BufferedWriter(new FileWriter("accountinfo.csv")); saveInformation = new PrintWriter("accountinfo.csv"); saveInformation.println("Changed Text File..."); writer.write("Changed Text file..."); } catch ( IOException e) { } finally { try { if ( writer != null ) writer.close( ); if (saveInformation != null) saveInformation.close(); } catch ( IOException e) { } } }

I have also tried to use the AssetManager, couldn't get that working. Also, I tried to use all above listed methods with relative file path and absolute file path. Each of these would similarly return the same error "java.lang.IllegalArgumentException: File contains a path separator".

Any help or feedback on the matter would be immensely very much greatly incredibly much appreciated!

Isn't the format of dataPath String? Although I wrote the following code, but A wasn't called. Why isn't the println("A") called?

String data_path = dataPath("test"); if(data_path == dataPath("test")) { println("A"); } else { println("B"); }

I'm playing with the 3.0a versions and have been using 5 for a while and upgraded to 9 after a format. I see quite a lot has changed (awesome!), but am finding some things not working. I hope I did enough research before posting here.

I'm using 'sketchPath' to determine the path of the sketch to open some files in my data folder
String UBUPFile = sketchPath + "/data/UBUP.bin";
Where this has been working fine up until 3.0a5, in a9 it produces the following error
The field PApplet.sketchPath is not visible
There doesn't seem to be anything in the revisions.txt, unless I missed something

I've followed these steps in creating Processing 3 sketches in IntelliJ. I would now like to use saveFrame() to export images from my sketch, but I have no idea where the frames are saved to. Related to this, if I wanted to load an image file, where would I place it in my project?

Thanks in advance!

I've a question, How to save an image in other folder than the root folder please ?

Thank you all :)

I'm trying to save a PImage and I'm getting the famous "PImage.save() requires an absolute path...". The PImage.save() code reference doesn't work either.

size(100, 100);
PImage tower = loadImage("tower.jpg");
PImage newImage = createImage(100, 100, RGB);
newImage = tower.get();
newImage.save("outputImage.jpg");

Any idea? It should work. I'm working with the last version, and Mac OSX.

thanks!

else if (hb0.value >= hb0.max) {

        image(images[frameNum/10 %images.length], 800, 600);     

        port.write(1); 


        println("Here is the achievment"); 
        image(achievment2, 700, 100);
        String words = "Achievement achieved";
        String[] list = split(words , " ");

        saveStrings("file.txt", list);
        println("They are saved");

When I use saveFrame() to save a projects current canvas, I usually wanna have this result: Projectname-20161230-184555.png which usually corresponds to following line:

saveFrame(Project+"-"+year()+month()+day()+"-"+hour()+minute()+second()+".png");

(yes, I'm from Europe, I like my months in front of my days :P)

The only real issue is that every function returns exactly what it is supposed to (which is totally right): When it is 8 am for example it returns an 8 when I call hour(). If I want to auto-sort the files though I need the 0 in front of every digit that doesnt have 2 digits, so I came up with this (quite hacky) solution (titled as void savePNG() because it isn't a one-liner anymore so I can call it):

void savePNG() {
  if (second()<10) {
    saveFrame(Project+"-"+year()+month()+day()+"-"+hour()+minute()+"0"+second()+".png");
  } else if (minute()<10) {
    saveFrame(Project+"-"+year()+month()+day()+"-"+hour()+"0"+minute()+second()+".png");
  } else if (hour()<10) {
    saveFrame(Project+"-"+year()+month()+day()+"-"+"0"+hour()+minute()+second()+".png");
  } else if (minute()<10 && second()<10) {
    saveFrame(Project+"-"+year()+month()+day()+"-"+hour()+"0"+"0"+minute()+"0"+second()+".png");
  } else if (second()<10 && hour()<10) {
    saveFrame(Project+"-"+year()+month()+day()+"-"+"0"+hour()+minute()+"0"+second()+".png");
  } else if (minute()<10 && hour()<10) {
    saveFrame(Project+"-"+year()+month()+day()+"-"+"0"+hour()+"0"+minute()+second()+".png");
  } else if (second()<10 && minute()<10 && hour()<10) {
    saveFrame(Project+"-"+year()+month()+day()+"-"+"0"+hour()+"0"+minute()+"0"+second()+".png");
  } else {
    saveFrame(Project+"-"+year()+month()+day()+"-"+hour()+minute()+second()+".png");
  }
}

And yes, I forgot about months and days here aswell.

Is there an easier way or is that just the way it's supposed to be?

   if (keyCode == ENTER){ //<>//
    open(dataPath("game.exe")); 

exit();

neither this one:

  if (keyCode == ENTER){ //<>//
   launch(dataPath("game.exe")); 

exit();

On mac and processing 2.0, open(dataPatch()) work perfect. On W10 I can't do that on any way even using Processing 2.0, 3.0, open or launch command.

I hope anyone know how to fix that... thanks a lot...!

I am moving to IntelliJ with my Processing projects and and right now I am desperatly trying to load a .vlw-File into my Application within my extended PApplet-Class. Using the Processing-IDE, all I had to do was creating the data folder and loading the Font with the loadFont-method. But now I have to locate the data folder myself which did not work right now for me. Where the heck do I have to place it?

Thanks!

In main project file:

Map map;

void setup(){
...
map = new Map();
...
}

In Map's constructor, where (members) pgMap is a PGraphic and imgMap is a PImage, I create a graphic draw some stuff on it, save it out then reload it as an image:

...
//save to file
pgMap.save("map.png");

//re-load as an image
imgMap = loadImage("map.png");
...
}

Another of Map's methods:

void renderWorld() {
    image(imgMap, 0, 0);
}

If I call map.renderWorld() from draw() I get a null pointer/"map.png" not found error and sure enough map.png hasn't been created. If I comment out the single line in renderWorld() the map gets created normally and the program functions as expected!

I suspected a path issue but I've tried no path (as above), using a relative path to ./data and using an explicit path to /data but none of those work. A separate image used by the program stored in ./data loads from setup() without any path being specified:

loadImage("compass.jpeg");

I've also tried loading Map's image from setup(), rather than within the constructor like so:

map.imgMap = loadImage("map.png");

but that doesn't work either (also tried specifiying paths at that point).

This is on Linux Mint 32 bit with Processing 3.0.2, any help appreciated!

Thank you

i don't know how to add video or image like in code? error: Could not load movie file video1.mov

    /* @pjs preload="../georgios.jpg"; */
PImage img;

void setup() {
  //size(800,800, RGB);
  size(800,800, P2D);
  colorMode(RGB,1);
  background(0);
  //frameRate(60);
  img = loadImage("../georgios.jpg");
  img.resize(100, 100);
}

void draw() {
  background(0);
  image(img, 0, 0);
}

Strange thing is that if I comment out the framerate it displays the image but at the original size.

there has been another post about this, but no answer. Any ideas maybe? Thank you

thanks.

I can get launch to work fine if I point the string at a data path specific to that windows user. However, as this sketch is intended to be a menu to launch a bunch of games(not made in processing) that will be deployed to several different computers, I wanted all the application data to be self contained, so that I simply compile it, and not concern myself with where the .exe's are located.

this isn't working:

launch("data/games/game.exe");

Am I barking up the wrong tree here? thanks!

Any help is much appreciated!

Thanks

My processing project in Eclipse is using a txt file to store stuff. it all works ok until I try to Export the application. The process creates the "application.linux/", "application.macosx/" and "application.windows/" folders with the application things in it but my txt file is not there.

I did try what was propose here*, didn't work any better. I did with my txt file in a data/ folder in src/, with the txt file in a data/ folder at root level and with the txt file simply dropped at root level. No better luck

any idea ?

cheers

• if it isn't there already, copy/create the data directory into your Eclipse project (on the same level as the src dir)

so

• refresh your project in Eclipse (RMB -> Refresh, or F5). You should now see the data dir and its contents reflected in Eclipse.
