Hey there,

Hi there, 

Hey all,

I have two spheres drawn on the page and I need to get one sphere to rotate/orbit around the other at a set distance.

Can anyone tell me why this sketch isn't running? http://amandahwood.com/applet/

When I exported the applet it didn't run from my local files either.. it's supposed to play audio and display a black screen with text.

Thanks.

What I basically want is to have a few different states controlled by three keys m, k, and q.

So if 'm' is pressed it would bring the program into 1st state. If 'k' is pressed 2nd state. if 'q' pressed 3rd state.

Once one of the above states is chosen (let's say 1st state) the user would have another opportunity to choose m, k, or q within that state. So 1st state + m = do this, 1st state + k = do something else, and 1st state + q = do another thing.

The issue I'm running into is if m is pressed at all the program doesn't remember if it's already in the 1st state so it will just start over and go back into 1st state instead of doing the second request. Here is what my code looks like but 1st, 2nd and 3rd states are defined as Forward, Left and Right.

int gameState;
int FORWARD = 0;
//int 1left = 1;
//int 1right = 2;

void setup() {
 size(600, 600);
 background(0);
}

void draw() {
 smooth();
 
 if(keyPressed) {
  if (key == 'm') {
   background(255);
   gameState = FORWARD;
  } else if (key == 'k') {
   background(150);
   //gameState = 1left;
  } else if (key == 'q') {
   background(255, 0, 0);
   //gameState = 1right;
  }
 }
 
 if (gameState == FORWARD) {
   forward();
 }
}



void forward() {
 if (key == 'm') {
   // forward choice
  ellipse(300, 300, 50, 50);
 } else if (key == 'k') {
   //left choice
  rect(200, 200, 10, 10);
 } else if (key == 'q') {
   // right choice
  ellipse(10, 10, 30, 30);
 }
}

I'm wondering is there a way for the program to remember it's already in a state or possibly counting the keyPresses?? So if m is pressed once do this if m is pressed twice do this?

Hope I made sense.

This is the base code for a four way pong game my group and I are trying to create. So that four different players can play over a network. What we need is for the ball to bounce off of all four paddles. I know there are collision detection examples on Processing.org but for the sake of this program I'm wondering is it possible to create collision detection using color?

So for example: When white (255) hits grey (100) go the other direction.

Is there a simple way of implementing this?

should read in println "hit"and score will be added.

Currently I'm trying to program using the toxiclibs library found here:
http://toxiclibs.org/downloads/

The problem is my MacBook Pros sound card only supports left to right panning and it has been the most impossible search finding a sound card that works with it. I need 3D audio capabilities.  I've tried two of Creative's newest versions (yes I know they're for windows but I've heard they work) they do play audio through them but do not fix the issues within my program.

Can anyone recommend something? Thank you in advance!

Please can you help me determine why this code keeps giving me null errors? It displays all the images one by one but then it errors once it reaches the end of the array. Why doesn't it continue to loop?

int maxImages = 24;
int imageIndex = 0;
PImage[] images = new PImage[maxImages];

String api  = "http://api.flickr.com/services/rest/?method=flickr.tags.getClusterPhotos&";


void setup() {
  size(500, 500);

  //text - Free text search. Searches the title, description or tags that contain this text.
  //page - Which page of results you want returned
  //per_page - Number of photos to return per page
  //api_key - Required to access API

  String query = api + "tag=monkey&cluster_id=1&format=rest&extras=url_o&api_key=bd7435660785b923332b224789d33c93";
  println("Our final query URL:" + query);
  println("**********************");

  XMLElement xml = new XMLElement(this, query);
  println(xml);

  XMLElement[] photoTag = xml.getChildren("photos/photo");
  for (int i = 0; i < photoTag.length; i++) {
//println(displayPhoto);

  String farm = photoTag[i].getString("farm");
  String server = photoTag[i].getString("server");
  String id = photoTag[i].getString("id");
  String secret = photoTag[i].getString("secret"); 
  String img = "http://farm"+farm+".static.flickr.com/"+server+"/"+id+"_"+secret+".jpg";
  println(images);
  images[i] = loadImage( img );
  }
}

void draw() {
  background(0);
 
  image(images[imageIndex], 0, 0);
  imageIndex = (imageIndex + 1) % images.length;
 
  frameRate(1);
}

The XML file for Flickr search results doesn't actually display the url with the .jpg name in it - so I'm a little confused at how to get the image to display in Processing. Usually you can just get.Children but again the XML doesn't display the full url for an image. Here's my code so far...

PImage img;
String api  = "http://api.flickr.com/services/rest/?method=flickr.tags.getClusterPhotos&";

HashMap<String, Integer> count = new HashMap();
void setup() {
  size(800, 800);
 
  //text - Free text search. Searches the title, description or tags that contain this text.
  //page - Which page of results you want returned
  //per_page - Number of photos to return per page
  //api_key - Required to access API
 
  String query = api + "text=cat&per_page=50&api_key=bd7435660785b923332b224789d33c93";
  println("Our final query URL:" + query);
  println("**********************");
 
  XMLElement xml = new XMLElement(this, query);
  XMLElement displayPhoto = xml.getChild("photos/photo");
 
  PImage photo = loadImage( displayPhoto.getContent() );
   image(photo, 0, 0, width, height);
  println(xml);
 
}

Can anyone help me out? I'm not interested in using a library I'd just like to keep it simple. Thanks.

Hey guys,

So this is my code so far...

String consumerKey = "*************************";
String consumerSecret = "*****************************";
String accessToken = "***********************************";
String accessSecret = "*******************************";
AccessToken token;


Twitter myTwitter;

void setup(){
   myTwitter = new TwitterFactory().getInstance();
   myTwitter.setOAuthConsumer(consumerKey, consumerSecret);
   token = new AccessToken(accessToken, accessSecret);
   myTwitter.setOAuthAccessToken(token);
 
  try{
    Query query = new Query("@amwood91");
    query.setRpp(100);
    QueryResult result = myTwitter.search(query);
  
    ArrayList tweets = (ArrayList) result.getTweets();
  
    for(int i = 0;i<tweets.size();i++){
      Tweet t = (Tweet) tweets.get(i);
      String user = t.getFromUser();
      String msg = t.getText();
      Date d = t.getCreatedAt();
      println("Tweet by" + user + "at" + d + ": " + msg);
    }
  }
  catch(TwitterException te){
    println("couldn't connect: " +te);
  }
 
}

What I want to do is search for keywords BUT only from a specific users timeline.

Any ideas???

Hi there,

I've been trying to use the Tweet Stream library for processing to track keywords that are tweeted by a specific user. Is this possible and am I using the right library? I'm a bit new to Processing so I'm sure it's a simple solution and I'm just not getting it. Any similar projects or any idea where to start with the code for this?

Thanks
