hello!

i need some help in how to use a printer to print out some info.
i searched the forums and only found topics about printing whats on screen.

im working on a project that users will do some procedures, and then, based on what users did, make the applicative to print out a ticket to be given to each user.

what i want to print is not on screen. i just want to print a string or some variables.

is there some easy way of doing that?

thanks in advance.

and sorry for the english and other issues.

like i expressed in this state-of-the-art image i made on gimp.

thanks in advance.

hello to all!

im new to programming and i am trying to make a class of objects that detecs another objects.
like a game, where the character collides with the environment.

i made a simple primitive test that worked fine... untill i decided to add a sencond object.
the first objects works fine and it "knows" when the "player" is nearby. the second acts like nothing is happening.

i dont have a clue why.

the code:

1. int x, y;
2. //if left, right, up or down (in this order) directions are possible
3. boolean esq, dir, aci, aba;
4. ArrayList objs;
5. void setup(){
6.   objs = new ArrayList();
7.   size(800, 600, P2D);
8.   x = y = 100;
9.   //initialy, all directions are possible
10.   esq = dir = aci = aba = true;
11.  
12. }
13. void draw(){
14.   background(0);
15.   //the "player"
16.   fill(255);
17.   rect(x, y, 10, 10);
18.   //add 1st object 
19.   objs.add(new Obj(200, 200));
20.   //add 2nd object (uncomment to work)
21.   objs.add(new Obj(400, 300));
22.   for (int i = objs.size()-1; i >= 0; i--){
23.       Obj t = (Obj)objs.get(i);
24.       t.Onde();
25.       t.Mostra();
26.   }
27.  
28.   textSize(20);
29.   fill(255);
30.   text("acima " + aci + " abaixo " + aba + " esquerda " + esq + " direita " + dir, 15, 15);
31.   text(mouseX + " " + mouseY, 30, 30);
32.   text(x + " " + y, 45, 45);
33. }
34. class Obj{
35.   int X, Y;
36.  
37.   Obj(int eixoX, int eixoY){
38.     X = eixoX;
39.     Y = eixoY;
40.   }
41.  
42.   void Onde(){
43.    
44.     //tests collisions   
45.     if ((y + 11 > Y) && (Y + 31 > y)){
46.       if (x + 11 == X){dir = false;}
47.       else if (x == X + 31){esq = false;}
48.       else{esq = true; dir = true;}
49.     }
50.     else if ((x + 11 > X) && (X + 31 > x)){
51.       if (y + 11 == Y){aba = false;}
52.       else if (y == Y + 31){aci = false;}
53.       else{aba = true; aci = true;}
54.     }
55.     else{aci = aba = esq = dir = true;}
56.   }
57.  
58.   void Mostra(){
59.    
60.     //displays the objects
61.     fill(200, 100, 100);
62.     rect(X, Y, 30, 30);
63.   }
64. }
65. void keyPressed(){
66.   if (key == CODED){
67.     if (keyCode == UP){
68.       if (aci){y -= 1;}
69.     }
70.     else if (keyCode == DOWN){
71.       if (aba){y += 1;}
72.     }
73.     else if (keyCode == RIGHT){
74.         if (dir){x += 1;}
75.     }
76.     else if (keyCode == LEFT){
77.         if (esq){x -= 1;}
78.     }
79.   }
80. }
81. void mouseClicked(){
82.   x = mouseX;
83.   y = mouseY;
84. }

any help?
thanks in advance.
sorry if theres any "engrish"... my first language is portuguese.

EDIT: i forgot to say: i read lots of posts about collisions and stuff. all people cares are about circles colliding... oh god!
and, if i posted in the wrong forum, please, move it to the right one.
