did you creat the file ufo_awesome.json at all?

does the content look ok in notepad?

do you have the spelling of ufo_awesome.json exactly the same in the code and your file name on the hard drive?

              

               

                 It must be in the project's "data" folder.
               
              
 
see
http://www.processing.org/reference/loadJSONObject_.html
etc.

What version of Processing do you use?

yeah, you should update to the newest version

in line
json = loadJSONObject("ufo_awesome.json");
maybe the
name json irritates him, try jsontest
jsontest = loadJSONObject("ufo_awesome.json");

also you must use
jsontest = loadJSONObject("ufo_awesome.json");
after the command size

also maybe the name of your sketch is irritating him (when the name is the same as a class e.g. or is json?)

this works for me

1. // The following short JSON file called "data.json" is parsed
2. // in the code below. It must be in the project's "data" folder.
3. //
4. // {
5. //   "id": 0,
6. //   "species": "Panthera leo",
7. //   "name": "Lion"
8. // }
9. JSONObject json;
10. String stateString="Press 1 or 2";
11. void setup() {
12.   size (800, 800);
13.   background(0);
14. }
15. void draw() {
16.   background(0);
17.   fill(255);
18.   text ("1 - save JSON", 111, 111);
19.   text ("2 - load JSON", 111, 131);
20.   fill(255, 2, 2);
21.   text (stateString, 111, 181);
22. }
23. void keyPressed() {
24.   switch(key) {
25.   case '1':
26.     saveTest() ;
27.     break;
28.   case '2':
29.     loadTest();
30.     break;
31.   default:
32.     // do nothing
33.     stateString="Press 1 or 2";
34.     break;
35.   } // switch
36. } // func
37. //
38. // ----------------------------------------------------------
39. void saveTest() {
40.   json = new JSONObject();
41.   json.setInt("id", 0);
42.   json.setString("species", "Panthera leo");
43.   json.setString("name", "Lion");
44.   saveJSONObject(json, "data/new.json");
45.   println ("saved");
46.   stateString="saved";
47.   // Sketch saves the following to a file called "new.json":
48.   // {
49.   //   "id": 0,
50.   //   "species": "Panthera leo",
51.   //   "name": "Lion"
52.   // }
53. }
54. // ----------------------------------------------------------
55. void loadTest() {
56.   json = loadJSONObject("new.json");
57.   int id = json.getInt("id");
58.   String species = json.getString("species");
59.   String name = json.getString("name");
60.   println(id + ", " + species + ", " + name);
61.   stateString="loaded:    " + id + ", " + species + ", " + name;
62.   //
63.   // Sketch prints:
64.   // 0, Panthera leo, Lion
65. }
66. //
