Hey all,

Is there a way to use the javax.swing.*; library with the processing.core.*; library, all in a java project in eclipse? If you are firmiliar with the swing library, you know it creates a new runnable and then executes a class. It requires all objects inside the displayed JFrame to be parented by a JPanel which is, in turn, parented by said JFrame. Problem is, how would I mount a processing component like an ellipse, onto a JPanel? Or, mount a JComponent (swing component/object) onto an existing PApplet? Or even better, mount the PApplet onto the JFrame.

I cannot figure out what the problem is with this program. I want to, for each of the characters in the input, obtain the appropriate replacement, and fill a second char array with the results. This is what I have, and the highlighted line returns a NullPointerException.

2. char ec[][] = {{'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z'},
3.                {'O', 'N', 'E', 'W', 'R', 'D', 'S', 'T', 'Y', 'A', 'B', 'C', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'P', 'Q', 'U', 'V', 'X', 'Z'}};
4.                
5. String input = "ANDREW";
6. String encryption;
7. char[] tempChars = input.toCharArray();
8. char[] afterChange;
9. 
   
10. void setup() {
11.   println(ec[0][0]);
12.   println(ec[1][0]);
13.   for(int pos = 0; pos < tempChars.length; pos++) {
14.     for(int scroll = 0; scroll < 26; scroll++) {
15.       if(tempChars[pos] == ec[0][scroll]) {
16.         afterChange = append(afterChange, ec[1][scroll]);
17.       } else {
18.       }
19.     }
20.   }
21.   encryption = afterChange.toString();
22.   println(encryption);
23. }
24. 
    
25. void draw() {
26. }

Is there any way I could encrypt data, such as a password (string) to be sent over the net? I don't really have any code, just a thought.

I am making a game, (just started, figuring out basics, dont have much code), that will eventually allow the user to save the game into a file. I am going to use saveStrings, and hide the txt file into a .plw (faux extention), so users can't easily hack the game. I will have many variables (ex. life, points, etc.) controlling the state of the game, and I would like to consolidate them into one file. Can I do something like saveStrings("SavedGame.plw", aString + anotherString); ? Thanks in advance. This is my (not working) code so far:

 What I get is a overwritten file that displays:

[0] "27"

[1] "48"

What I want is a file that reads:

[0] "Hello, My name is Andrew"

[1] "Hello, My name is Andrew"

[2] "Hello, My name is Andrew"

[3] "Hello, My name is Andrew"

[4] "Hello, My name is Andrew"

[5] "27"

[6] "48"

Thanks,

andrewgies17

      Basically, what I want the program to do is try to read a file, and If it exists, continue. If it doesn't exist, create the file and then read it. This is the code I have so far:

2. try {
3.       String[] input = loadStrings(System.getProperty("user.home") + "/Paint Files/" + "ccSave.txt");
4.     } catch (NullPointerException input) {
5.       saveColors();
6.       String[] input = loadStrings(System.getProperty("user.home") + "/Paint Files/" + "ccSave.txt");
7.     }

Thanks,

      I have been using prosclipsing to integrate processing into eclipse for quite sometime. I decided to create a Java Project and mess around with some non-processing functions I learned in an oracle javadoc. When I try to run it, it opens a processing.core.PApplet file for a split second and then returns this error in the console.

Usage: PApplet <appletname>

For additional options, see the Javadoc for PApplet 

I am quite confused because I didn't add the processing.core.* file to the project file or attempt to import the file. I have no other processsing or prosclipsing projects open at the time. I have tried restarting eclipse.

Thanks all,

I have a new problem for you. I need to loadString instead of loadStrings. Basically, I need to loadStrings but load the entire file into one String instead of each line into an Array of Strings[]; this is my test .txt file to load.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec enim est, fermentum nec tristique nec, gravida id purus. Pellentesque commodo semper purus, quis tincidunt odio sodales quis. Ut vel condimentum erat. Pellentesque vestibulum risus a augue dignissim sit amet facilisis. 

And this is what I want to return when I run this code:

1. String testText;
2. testText = // This is where I need to load the text file...all into one string.
3. print(testText);

      I have made a program that will save custom colors that the user has defined....More information about it can be found in this post here...... Help Saving Variables....Processing Forums. I have almost completed it but have one more problem. What I want is to have a few rows of little circles.....each filled with the color that they represent, so if the user saved customColors[0], (The array storing the colors)  as a light green color, the first color there would be light green. What I want is if the color corresponding to any given circle is not set, the color would be set to white. I used the try/catch structure to catch the ArrayOutOfBoundsException when the position is not set, and it works fine. The problem is, when there is no error to catch, that is, if the position exists in the array. The fill color remains white. I know that the catch statement is not run, because of the print() I placed in there. Why are the functions in try, not running if there is no exception. This is the code in question:

2. int y = 200;
3. int x = 140;
4. color[] customColors = new color[0];
5.  
6.   void setup() {
7.     smooth();
8.     size(400, 400);
9.     ellipseMode(CENTER);
10.     stroke(0, 0, 0);
11.     strokeWeight(2);
12.     // customColors = append(customColors, color(255, 255, 255));  //This is commented in or out whether or // not I want to cause the error.
13.     
14.     try {
15.       fill(customColors[0]);
16.       ellipse(x - 120, y - 12, 20, 20);
17.      } catch (ArrayIndexOutOfBoundsException customColors) {
18.       print("Caught");
19.       fill(255, 255, 255);
20.       ellipse(x - 120, y - 12, 20, 20);
21.      }

Thanks-

      I am making a program modeled after MS Paint, and I want to add a custom color function. I already have a color selector, and I have figured out how to add, and delete the users colors. The problem is, when the user closes the application, (I am going to export it as so eventually), I want it to save the colors the user selected. I can't figure out how to save the variables, hopefully as a simple file like a txt. My program solely works with variables of the color type, when managing default, and color selected variables. Thanks in advance....

If you need other information, please ask for it. I would like to have a solution as quickly as possible and am ready to assist you in any way possible.

I tried installing all levels, including 7, and running them separately, together, and in combinations. 

This one, I have no idea what it means:

This is what I had installed for the above error messages, even though the message was similar throughout all of my test runs.

Thanks in advance for any help you can offer, and sorry if this is a dumb question, I dont have any experience with android's platform.

      I am currently making an application modeled after MS Paint. I would like to make/edit my own menu items - the ones in the top left hand corner on macs, encircled in red.

I'm wondering if there is some sort of command that allows me to edit these menus, hopefully without too much complications. I want my program to look more professional.

Thanks,

Andrew :)

The constructor sketch_mar23e.toggle(int, int, boolean) is undefined.

My code is below: 

2. toggle T;
3. 
   
4. void setup() {
5.   size(400, 400);
6.   background(255);
7.   T = new toggle(100, 100, true);
8. }
9. 
   
10. void draw() {
11.   T.update();
12.   T.display();
13. }
14. 
    
15. class toggle {
16.   
17.   boolean active = false;
18.   int x;
19.   int y;
20.   
21.   void toggle(int tempX, int tempY, boolean tempActive) {
22.     active = tempActive;
23.     x = tempX;
24.     y = tempY;
25.   }
26.   
27.   void display() {
28.     fill(255);
29.     stroke(0);
30.     rectMode(CENTER);
31.     rect(x, y, 40, 40);
32.     if(active == true) {
33.       line(x - 20, y + 20, x + 20, y - 20);
34.       line(x - 20, y - 20, x + 20, x + 20);
35.     }
36.   }
37.   
38.   void update() {
39.     if(mousePressed) {
40.       if(mouseX < x + 20 && (mouseY < y + 20) && (mouseX > x - 20) && (mouseY > y - 20) && (active == false)) {
41.         active = true;
42.       } else if(mouseX < x + 20 && (mouseY < y + 20) && (mouseX > x - 20) && (mouseY > y - 20) && (active == true)) {
43.         active = false;
44.       } else {
45.       }
46.     }
47.   }
48.   
49.   boolean getValue() {
50.     if(active == true) {

 The Java JAR file 

"Paint_V_4_Pokemon_Sprite_Version"

could not be launched.

Check the console for possible error messages

The console didn't say anything relevant. 

I cannot export as a pde because the customer doesn't have processing.

 

Note:      I did not move the file outside of the original export position

this is the heirarchy: the selected file on the right is the one I need to open

2.   if(keyPressed) {
3.     if(key == ' ') {
4.       PImage drawingArea = get(40, 20, 720, 780);
5.       drawingArea.save("My Drawings/" + "My Drawing" + drawingNum + ".png");
6.       drawingNum ++;
7.     }
8.   }

The problem with this is that it creates a "My Drawings" directory inside the sketch folder.

I have also tried replacing line 5 with

1. drawingArea.save("Hard Drive/Users/Andrew/Desktop/My Drawings/" + "My Drawing" + drawingNum + ".png");

It ended up creating a "Hard Drive" directory with all the Sub Directories in order and the final image file in place but the whole thing started in the sketch folder again. 

Any help would be greatly appreciated.

Note... I am intermediate so any coding examples would aid to my understanding of an explanation.
