I'm trying to display whether a user is online or offline by using text(). I have two different methods, either one printing based on a condition, but when that condition changes, the text does not. I'm getting a readout in the console so I know that the condition statement is switching, but the displayed text isn't..

Here's the code - you can find the text methods towards the end of draw()

2. import processing.serial.*;
3. Serial port;
4. PFont f;
5. 
   
6. void setup() {
7.   size(640, 360);
8.   port = new Serial(this, "COM3", 9600);
9.   port.bufferUntil('\n');
10.   f = createFont("Arial",16,true);
11. }
12. 
    
13. void draw() {
14.   background(0);
15.   
16.   int i=0;
17.   int temp=-1;
18.   int lastLogin = 0, lastLogout = 0;
19. 
    
20.   String[] lines = loadStrings("C:/McMyAdmin/Minecraft/plugins/BeardStat/stats.yml");
21.   
22.   println("there are " + lines.length + " lines");
23.   
24.   String searchLogin = "stats-lastlogin";
25.   while(i < lines.length){
26.     int index = lines[i].indexOf(searchLogin);
27.     if(index >= 0){
28.       String sub1 = lines[i].substring(index+17);
29.       //println(sub1);
30.       lastLogin = int(sub1);
31.     }
32.     i++;
33.   }
34.   
35.   i=0;
36.   
37.   String searchLogout = "stats-lastlogout";
38.   while(i < lines.length){
39.     int index = lines[i].indexOf(searchLogout);
40.     if(index >= 0){
41.       String sub2 = lines[i].substring(index+18);
42.       //println(sub2);
43.       lastLogout = int(sub2);
44.     }
45.     i++;
46.   }
47.   
48.   textFont(f,16);
49.   fill(255);
50.   
51.   if(lastLogin < lastLogout){
52.     println("User is logged out.");
53.     port.write(0);
54.     text("User is logged out.", 10, height/2);
55.   } else {
56.     println("User is logged in.");
57.     port.write(1);
58.     text("User is logged in.", 10, height/2);
59.   }
60.   
61.   myDelay(5000);
62. }
63. 
    
64. void myDelay(int ms){
65.   try{    
66.     Thread.sleep(ms);
67.   }
68.   catch(Exception e){}
69. }

EDIT - I have not noticed that if I leave it run for a while, the text does eventually update, but not instantly. The console messages do change instantly though, so it it something to do with loading the text?
