origami alphabet

[3 Replies]

I have made a sketch which types origami letters. The more often a letter occurs in a string, the more it unfolds. It uses tweets as a source, but once you click, you can type your own text. Now i want to make a cool animation at the start of the sketch saying 'Unfold'. The max steps is 6 and I want al the letters to begin at the first step and end at the last step with intervals of 2 seconds. Can anyone help me? I have uses png files as images for the letters.

(this is the class)

class typedLetter{

String typedChar;

int count;

float letterAlpha = 0;



typedLetter(String typedChar){

this.typedChar = typedChar;

letter lInst = letters.get(typedChar);

//letter_shapes = lInst.letter_shapes;

//println(typedChar);

this.count = lInst.count;

lInst.count++;

lInst.count = constrain(lInst.count,0,max_steps);

}

void display(){

tint(255,letterAlpha);



letterAlpha += fadeSpeed;

letterAlpha = constrain(letterAlpha,0,255);



letter lInst = letters.get(typedChar);

PImage origami = lInst.letter_shapes.get(count);

image(origami,0,0);

//println("DISPLAY");

}

}

class letter {

String letter;

ArrayList<PImage> letter_shapes;

int count;

letter(String letter) {

this.letter = letter;

letter_shapes = new ArrayList<PImage>();

for (int i=0; i<=max_steps; i++) {

String filename = "letter_"+this.letter+"_step_"+(i+offset)+".png";

//println(filename);

PImage letter_shape = loadImage(filename);

letter_shapes.add(letter_shape);

}

}

String toString() {

return "[LETTER OBJECT] I am the letter " + letter;

}

}

this is the twitter feed

import twitter4j.*;

ConfigurationBuilder cb;

Twitter twitter;

ArrayList<String> getTweets() {

Query query = new Query("origami");

ArrayList<String> tweet_texts = new ArrayList<String>();

try {

QueryResult result = twitter.search(query);

ArrayList tweets = (ArrayList) result.getTweets();

for (int i = 0; i < tweets.size(); i++) {

Status t = (Status) tweets.get(i);

String tweet_msg = t.getText();

int q_count = 0;

for (int j=0; j<tweet_msg.length(); j++) {

if (tweet_msg.charAt(j) == '?') {

q_count++;

}

}



if (q_count < 5) {

tweet_texts.add(t.getText());

}

};

}

catch (TwitterException te) {

//println("Couldn't connect: " + te);

};

return tweet_texts;

}

void initTwitter() {

cb = new ConfigurationBuilder();

cb.setOAuthConsumerKey("uEpelg8CTgvjN4Z99s9iaw");

cb.setOAuthConsumerSecret("sDR7oeBkNKY9AlBxXq2t6XRm4fbXqzxlZdpCtaHjM");

cb.setOAuthAccessToken("46233081-oBUW6fXkb03sD1SENtZbSsxmuYK9ykLTFfIQXdhaF");

cb.setOAuthAccessTokenSecret("2EGcFHucVGSGFc2d2F9ufPbe7tlqyIxdeHe8DqOpk");

twitter = new TwitterFactory(cb.build()).getInstance();

}

void getNewTweet(){

ArrayList<String> tweets = getTweets();

/*for (int i=0; i<tweets.size(); i++) {

String tweet = tweets.get(i);

println(tweet);

} */

String tweet = tweets.get(floor(random(tweets.size())));

for(int i = 0; i<tweet.length(); i++){

typeChar(tweet.charAt(i)+"");

}

//println(tweet);

}

this is the rest
