Hi,
I just want to share my latest project - Simple Investment Tracker, which, of course, I made with Processing. Here goes the description....

-------

Download link for Mac OSX

Free yourself from minute-by-minute wall street hypes, and focus on your long-term investment goals and diversification.

—————————

I wanted a simple way to track my investment. I don’t want to log in to my broker’s website every time I need to check the total balance. The search engine results distract my focus and show me too much information. I am not a day trader and never will be, but I want to make sure I’m heading in the right direction – that my investment is appreciating over the long-term, and also track the proper asset allocation once in a while.

This software is not meant for real-time tracking nor it provides any prediction. You may want to use it to update any changes (buy/sell activities) to your long-term investment. You may not want to open this program every day.

The software is developed with Processing, and it gets real-time and historical stock data from Yahoo.

I started working on this project to meet my personal needs, and now I’m releasing as an open-source software (under GNU GPL license) in case anyone has similar interests as I do, and looking forward to any feedbacks. Please visit my website for the latest release and more information. Please visit my github for bug reporting, etc.

Thank you.

controlp5 button stroke color

Hi,
Is there a way to add a stroke outline around controlp5 button?
I've looked at the reference, and these are functions I found related to colors:

setColorBackground( )
setColorForeground()
setColorLabel()
setColorActive()

but none of it adds a stroke. with textfield, i can add a stroke using setColorForeground(), but with button it works different..

P2D and noSmooth() not working as expected on Macbook Pro with Retina display

1. void setup() {
2. size(400, 400, P2D);
3. noSmooth();
4. }
5. void draw() {
6. background(30);
7. noFill();
8. stroke(255, 70);
9. for (int i=0; i<width; i+=10) {
10. for (int j=0; j<height; j+=10) {
11. point(i, j);
12. }
13. }
14. }
Running the code above, nothing shows up on the screen, just the dark grey background.

When I remove P2D, and render with the default renderer, everything looks fine, BUT, when I export that to application(mac os x), the dot grid is all broken apart.

What's more strange is that when I compare the result of the same program running in Processing IDE and MacOSX application,
1. background(30);
the background value is 40 in P5 IDE whereas Mac Application renders the color correctly.

Anybody has seen this happening?

Tested on Mac OSX 10.8.4 with 15 inch Macbook Pro with Retina Display

new object affecting the position of the previous ones

Hi,
I am creating a new box from the top of the screen with keyPress and the new box pushes down the previous boxes. It is a simple scrolling boxes. But I can't find a way for the new objects affect the previous objects' location.

I made it work with 2 boxes, but this is where I'm stuck. I'd appreciate any insights on this.
1. import java.util.Iterator;
3. ArrayList<Box> boxes = new ArrayList<Box>();
4. float newBoxHeight = 0.0;
5. int boxID = 0;
7. void setup() {
8. size(600, 600, P2D);
10. //create the first box on screen.
11. newBoxHeight = random(100, 200);
12. boxes.add( new Box(boxID, newBoxHeight) );
13. boxID++;
14. }
16. void draw() {
17. background(0);
19. Iterator<Box> it = boxes.iterator();
20. while ( it.hasNext () ) {
21. Box b = it.next();
22. b.update();
23. b.display();
24. if ( b.isOffscreen() ) {
25. it.remove();
26. }
27. }
29. println( boxes.size() );
30. }
33. void keyPressed() {
34. newBoxHeight = random(100, 200);
35. boxes.add( new Box(boxID, newBoxHeight) );
37. //need to know the new box loc and the one before.
38. Box b = boxes.get(boxID-1);
39. b.setTargetLocation( boxes.get(boxID).boxHeight );
41. boxID++;
42. println("key Pressed");
43. }
1. class Box {
2. float boxHeight;
3. PVector loc = new PVector(); //current location
4. PVector tloc = new PVector(); //target location
5. color boxColor;
6. int id;
8. Box(int _id, float _bh) {
9. id = _id;
10. boxHeight = _bh;
11. loc.y = -boxHeight;
12. //tloc.set(0, 0, 0);
13. boxColor = color( random(150, 250), random(140, 200), random(140, 200) );
14. }
16. /*
17. int getID() {
18. int _id = this.id;
19. return _id;
20. }*/
22. //how can i get tloc.y of the next box?
23. void setTargetLocation(float _nextTLoc) {
24. tloc.y += _nextTLoc;
25. }
27. boolean isOffscreen() {
28. return loc.y >= height;
29. }
31. void update() {
32. loc.lerp(tloc, .1);
33. }
35. void display() {
36. pushMatrix();
37. translate(loc.x, loc.y);
38. noStroke();
39. fill(boxColor);
40. rectMode(CORNER);
41. rect(0, 0, width, boxHeight);

43. }
44. }

PShape disableStyle() does not work in class

I have a Particle class that uses a SVG file to display graphics. What I want to do is to randomize the stroke and fill color for each particle using disableStyle(), but it doesn't seem to be working. It always displays the original svg style. When I have a simple setup and draw structure without using a class, disableStyle works just fine.
Any help would be appreciated!!
MacOS 10.8.2, Processing 2.0b8
import java.util.Iterator;

ArrayList<Particle> particles;

PShape s; //source file

void setup() {

size(1200, 800, P2D);

particles = new ArrayList<Particle>();

}

void draw() {

background(0);

particles.add( new Particle(s, new PVector(width>>1, height>>1)));

PVector gravity = new PVector(0, 0.5);

Iterator<Particle> it = particles.iterator();

while (it.hasNext ()) {

Particle p = it.next();

p.applyForce(gravity);

p.update();

p.display();

if (p.isDead()) {

it.remove();

}

}

frame.setTitle(int(frameRate) + " FPS");

}

class Particle {

PShape s;

PVector loc;

PVector vel;

PVector acc;

float lifespan;

float mass;

color fc; //fill color

color sc; //stroke color

float theta;

float rotInc;

Particle(PShape _s, PVector l) {

s = _s;

loc = l.get();

vel = new PVector();

acc = new PVector( random(-2, 2), random(-2, 2) );

I'm having trouble with this game program I'm making. you can control the spaceship with your mouse, and it will ease in to your mouse location. But sometimes, there is a random position jump. The default renderer is quite slow, so I'm using P2D. My target framerate is 60fps.

I'm guessing my update() function inside Spaceship class may have a problem, but it's been inconsistent. The default renderer seems fine and it's worse on my MacBook Air than my Macbook Pro with Retina.(I don't know if this is relevant.)

I attached a video that shows this strangeness.

Any help would be appreciated!

                   
                    Spaceship player;
                    int life = 10;
