can you post the code in a better way? Greetings, Chrisir If you need an answer, please send me a personal message since this forum doesn't notify.

hello,

here is the code in a better version.

there were some small erorrs

explanation
the function setup() runs only once (green in the code below)

the function draw() runs on and on
pac man is painted at pos x and y
using arc leaves its mouse open a bit
because z changes every time, he closes and opens his mouth all the time
to read more about arc, see http://www.processing.org/reference/

the function keypressed (in red below)
when you move cursor, x or y is changed by velocidad (speed)

1. int x=0;
2. int y=0;
3. int z=0;
4. float rot=0;
5. int velocidad=25;
6. //
7. void setup() {
8.   size(800, 500);
9.   smooth();
10.   frameRate(8);
11. }
12. //
13. void draw() {
14.   background(#213454);
15.   fill(255, 255, 0);
16.   text("use cursor to move pac-man", 13, height-20);
17.   //
18.   if (z==0) {
19.     z=1;
20.     arc(200+x, 200+y, 100, 100, QUARTER_PI+rot, TWO_PI-QUARTER_PI+rot);
21.   }
22.   else if (z==1) {
23.     z=2;
24.     arc(200+x, 200+y, 100, 100, QUARTER_PI-0.4+rot, TWO_PI-QUARTER_PI+0.4+rot);
25.   }
26.   else {
27.     z=0;
28.     arc(200+x, 200+y, 100, 100, 0+rot, TWO_PI+rot);
29.   }
30.   {
31.     // x=-200;
32.   }
33.   if (x>width-200) {
34.     x=width-200;
35.   }
36.   if (y>height-200) {
37.     y=height-200;
38.   }
39.   {
40.     // y=-200;
41.   } //
42.   fill(0);
43. 
    
44.   // eye
    
45.   arc(185+x, 185+y, 10, 25, 0+rot, TWO_PI-HALF_PI+rot);
46. }
47. void keyPressed() {
48.   if (keyCode==RIGHT) {
49.     x=x+velocidad;
50.     rot=0;
51.   }
52.   if (keyCode==LEFT) {
53.     x=x-velocidad;
54.     rot=PI;
55.   }
56.   if (keyCode==UP) {
57.     y=y-velocidad;
58.     rot=-HALF_PI;
59.   }
60.   if (keyCode==DOWN) {
61.     y=y+velocidad;
62.     rot=HALF_PI;
63.   }
64. }
65. //

okaaay thanks but what is z ?? and also rot ? my guess is rot is for rotation but what rotation is it degree ??

as said z just changes from one to two and back all the time. so with one value of z, mouth is open, with the other it closes. rot is for rotation and tells pac-man to look right, left, up or down. it is set in keypressed.

rot is in radians - from 0..2PI is a circle - see reference : radians. Greetings, Chrisir If you need an answer, please send me a personal message since this forum doesn't notify.
