associate text and picture

mariron

Hello, I have generative text, but would like associate some words with some pictures.

exemple : If I have : String[] alea = {"cat","dog"};

and I would like associate "cat" with PImage cat;

How to do ?

I'm lost.

Thank you fo all.

final HashMap<String, PImage> imgWords = new HashMap();

imgWords.put("cat", loadImage("cat.jpg"));
imgWords.put("dog", loadImage("dog.jpg"));

static final String EXT = ".jpg", words[] = {
  "cat", "dog"
};

final HashMap<String, PImage> imgWords = new HashMap();

void setup() {
  size(800, 600, JAVA2D);
  smooth(4);

  for (String w: words)
    imgWords.put(w, loadImage(w + EXT));
}

I have this error : "The file "blabla.jpg" is missing or inaccessible, make sure the URL is valid or that the file has been added to your sketch and is readable."

I have the file in the folder data. So it's good no ? Or I forgot something ? I search.

Thank you fo all.

Rather than just describe it, you should also provide the relevant code snippet of your problem!

Ok. I'm sorry. In fist time, I have no problem with my code. In second time, I have problem whith my code when I interact.

Snippet :

// forum.processing.org/two/discussion/6104/
// associate-text-and-picture

void mousePressed() {

  if (mouseX >= xText1 && mouseX <= xText1+textWidth(Mots1[randomText1]) && mouseY <= y && mouseY >= y-textFontSize) //Condition 
  {

    turn++;

    if (turn == 0) {
      isSelected1 = true;
    }
    else if (turn == 1) {
      isSelected2 = true;
    }
    else {
      isSelected3 = true;
    }
 for (String m : Mots1){
if (isSelected1 && !isLocked1) {
  poem1 = finalMots1+Mots1[randomText1].toLowerCase(); //droite
  xPoem1Cible = largeurRandom+margeTexte; //position
  imgWords.put(a, loadImage(m + EXT));}
  isLocked1 = true; //boolean
    }

randomText1 = round(random(0, ancre1.length-1)); }

It's hard to figure out your snippet b/c there are many variables which were declared & initialized somewhere else!
What I can tell you is that we should avoid loading resources outside setup()!
Use loadImage() and put() its reference in the HashMap structure within setup()!

In addition to using a Map, you could also create an Object that contains a String and PImage. Depends on exactly what you need to do with the data.

Finally, I haven't use "HashMap" because I had problem with data folder. I have just read :

String EXT : ".png";
    if (isSelected1 && !isLocked1) { 
      poem1 = finalMots+Mots1[randomText1].toLowerCase();
      img1 = loadImage(Mots1[randomText1]+EXT);
      isLocked1 = true;
}

Thank you fo all.
