Starting and exiting from Functions

I have this processing app that contains 2 functions. 1st is called loadScreen. 2nd is called mainMenu. When the app initializes, it calls the function "loadScreen();". I set a timer inside this function so that after 5 seconds, it will jump to "mainMenu". The problem is that how do I stop my function and call another function? Is there a "break;" or "stop" function that I can use? Thanks!
1. ```
void loading() { //Code to load start screen  if (millis() - time >= wait) { time = millis();//also update the stored time image(loadingImage, 0, 0); } if (time/1000 == 5) { time=5000; // Stop here startMenu(); } } void startMenu() { //Code to load the real game text("Start", 350, 300); }

Setting borders for paddle & switching between screens (layers of screens)

I have 2 main bugs here mainly and the first one is:
1) When I move my paddle to the right side, it is supposed to have a limit and touch the border and stop there but when I past the border, I can see that it keeps jumping back. How do I solve this?

2) I have 3 screens and I want it that if I lose on Screen 2 (The actual game) I will move to Screen 3 (Game Over). Then I click "Menu" and can return to Screen 1 (main menu) and start the game again. Can someone help me with this. The screens seem to just be jumping around.

The Code:
2. int ballx = 50;
3. int bally = 50;
4. int motionx = 6;
5. int motiony = 5;
6. int screendisplay = 1;
7. PFont font;
8. float ballx2 = random(50,900);
9. int ballx1 = int(ballx2);
10. float bally2 = random (300,400);
11. int bally1 = int(bally2);
15. void setup() {
16. size(1000, 600);
17. }
19. void draw() {
20. if (screendisplay == 1) {
21. background (#AFE5EA);
22. fill(255);
23. rect(350, 300, 300, 100);
25. font = loadFont ("SegoeUI-Light-48.vlw");
26. textFont(font, 42);
27. fill(0);
28. text("Start", 450, 365);
30. if (mouseX>350 && mouseX<650 && mouseY > 300 && mouseY < 400 && mousePressed == true && screendisplay == 1) {
31. screendisplay = 2;
32. }
33. }
35. if (screendisplay == 2) {
36. background (#AFE5EA);
37. fill(255);
39. strokeWeight(6);
40. ellipse(ballx, bally, 50, 50);
41. ballx = ballx + motionx;
42. bally = bally + motiony;
44. if (ballx>970 || ballx<30) {
45. motionx = motionx * -1;
46. }
47. if (bally <30) {
48. motiony = motiony*-1;
49. }
51. rect(mouseX, 500, 150, 30);
52. if (500-bally<40 && ballx >mouseX && ballx < mouseX+150) {
53. motiony = motiony*-1;
54. }
58. if(mouseX + 150 > 1000){
59. mouseX = 850;
60. }
61. if(mouseX < 2){
62. mouseX = 3;
63. }
66. if (bally>570) {
67. screendisplay = 3;
68. bally = 500 - bally1;
69. }
72. }
74. if (screendisplay == 3) {
75. background(0);
76. font = loadFont ("SegoeUI-Light-48.vlw");
77. textFont(font, 42);
78. fill(255);
79. text("Menu", 450, 365);
80. if (mouseX>400 && mouseX< 600 && mouseY > 340 && mouseY < 470 && mousePressed == true) {
81. screendisplay = 2;
82. }
83. }
84. }

Random Function

Hello. I am trying to make a game of snake. There will be a question displaying on the top and I want it to be random. When the user uses his snake to eat the target food successfully, I want the question to regenerate into a different question. I have used a varible called "questions" and it works with the random() function. Before Void Setup, I have a line telling it to generate

float questions = random(1, 3);
int question = int(questions);

. I want to tell the program that when ever my snake touches my target food, it should regenerate the question and how do I do that? Thanks.

P.S. Just for more information, just like what I said, the program will first generate a number. Under void draw, I will post a question out according to the number that was generated. So if "2 == true" , question will appear.

Thanks!!!!
