How can I make my code more efficent when it comes to implementing sound files

edited May 2018 in Library Questions

as i have this set up as a tree and i want it to look better and work more effiecently than it already does So if you could help with my tree that would be greatly appricated

  • Remarks

    • setup() is very long so I advice to make a sub function initTree()

    • Node root; is only used in function initTree()- no need to make it global

    • remember: ctrl-t for auto-format in processing IDE

    • This: PImage[] scenes = new PImage[10]; is not in use

    Line image(currentScene.scene, 0, 0);

    Make this is a function in the class Node:

    void displayScene() {
          image(scene, 0, 0);

    and call it from draw() as currentScene.displayScene();

    Your sounds

    When each scene has a sound make the sound file part of the class Node scene

    SoundFile soundForTheScene;

    then instead of; in draw() say; in the function displayScene() within the class! Nice.

    function in the class Node is now:

    void displayScene() {
          image(scene, 0, 0);

    Best, Chrisir ;-)

  • thank you

  • edited May 2018

    Lines 88-164 should be gone then

    Not sure what this is

         currentScene.index =-8;

    minus is just that the sound is playing? Then use a boolean soundPlays in the class

  • in these lines:

    iterator.left = new Node("elganzabianca.png", 69,"Choose Left or Right for which couture

    you should also give the sound file name as parameter and load the sound in the constructor as you do with the image


    line 36 to 70:

    also you could have text file containing all data (scene number, image name, sound file name, scene text, child node numbers...) and read the text file and build the tree from there.
