Hi
I wrote this, but i cant seem to get the rectangle to start over again. If you visualize this as a road, I want the rectangle to change back to the bottom lane after it goes out of bounds in the top lane. I realise that putting:
1. if (x > width){
2. x=x2;
3. y=y2;
4. speed=speed2;
5. }
screwed everything up, but I can't think of an alternative.
1. float x = 0;
3. float x2 = 1000;
4. float y = 375;
5. float y2 = 250;
6. float speed = 5;
7. float speed2 = -5;
10. void setup() {
12. size(1000,700);
13. }
15. void draw() {
16. background(177);
17. move();
18. display();
19. line(0,500,1000,500);
20. line(0,250,1000,250);
21. line(0,375,1000,375);
22. }
24. void move() {
25. x = x + speed;
26. if (x > width) {
27. x = x2;
28. y = y2;
29. speed=speed2;
30. }
31. else if (x > width){
32. x2 = x;
33. y2 = y;
34. speed2 = speed;
35. }
37. if (keyPressed){
38. if (key == 'b' || key == 'B') {
39. x = x - speed*4;
40. }
41. if (key == 'a' || key == 'A') {
42. x = x + speed*4;
43. }
44. }
45. }
47. void display() {
48. fill(124, 200, 142);
49. rect(x, y, 250,125);
50. }
