Create your own adventure game -- adding images

Processing Coding Questions

I was making this choose your own adventure game and couldn’t figure out how to add images correlating to each situation (NOT options). I’m not done with the code, but could someone please help me out.

Example of images we want to use:

nicely done! Congrats!

for image: since the image is part of the screen (situation) you are in, make PImage scene; part of the class State.

in setup() say something like states[0].add_Image( "Beach.jpg" );

in the class State make a function add_Image and use loadImage here
look at loadImage in the reference

https://www.processing.org/reference/loadImage_.html

and in states[state].draw();
use image() : image(scene, width/2, height/2);

Formatting and Posting

When coding in processing use ctrl-t regularly, it gives you auto-format especially for indents.

Use it before posting in the forum. When posting here, tell the forum software where your code is.
Mark it with mouse and hit </> in the command bar.

As Chrisir say, format is important for posting here. And if you can, format the title of the post too. One of the objetives of this forum is make a space for asking for help, so its not necesary ask for it in the title.

Thanks you for helping me! Here’s what we got so far, but we’re still running into errors.

Be more specific

What kind of errors

6

this line

states[0].add_Image("Beach.jpg");

must be AFTER

states[0] = new State(0, "You just survived a plane crash and now have to fend for yourself on the Island");

and

  void add_Image() { 
    scene = loadImage("Beach.jpg");
  }

must be

  void add_Image( String imgName )  { 
    scene = loadImage(imgName);
  }
7

These types of error.

The method add_Image() in the type CODE_FOR_FINAL_.State is not applicable for the arguments (String)

8

ok

did you apply my changes

Yes, I did and a new error popped up.

you need to concentrate more

Here it is: Scene cannot be resolved to a variable

  • —>>>>> where did you define scene? In the class. So you must use it inside the class, not in the main function draw()

Where in the class State do you display the screen? In draw() inside the class - the function has the same name but it’s not the same function

Thank you it worked!

Sorry to bother again, my code ran into another problem. We got the picture to load in and we have options for our survival game and the options have links attached to them to drag you onto another screen for more options. But, once we put the image onto the screen, it would not allow me to press on the options and it would make me stay on the starting screen. We have tried to move the image code around the void draw inside the class State but nothing has worked. Do you have any ideas? Sorry for all the questions, we’ve been learning code for a few months now…still newbs

class Pair {
  String txt;
  int id;
  Pair(int iid, String itxt) {
    id = iid;
    txt = itxt;
  }

  PImage scene;

  Pair here;
  ArrayList<Pair> links;
  State (int iid, String itxt) {
    here = new Pair(iid, itxt);
    links = new ArrayList();
  }
  void add_link(int to_id, String option_txt) {
    links.add(new Pair(to_id, option_txt));
  }
  void draw() {
                 image(scene,  width/4, height/4);

    text(here.txt, 20, 20, width-40, height/2-20);
    for (int i=0; i< links.size(); i++) {
      text(links.get(i).txt, 20, height/2+20+(i*height/4), width-40, height/4);
    }

The only thing I see:

The function draw() in the class always executes this line:

image(scene,  width/4, height/4);

but when you haven’t added a image for that scene, sketch will crash since scene (the image) is not defined. (Error message in processing Null Pointer Exception)

You can check if the image is there:

  void draw() {
    if (scene!=null) 
      image(scene, width/4, height/4);

to avoid the error : if (scene!=null)

Remark

use add_Image in setup() to add images to the other states. The states without image just don’t show an image then (if you have the new line above).

Otherwise the code runs here, the image does not disturb the mouse input
