mousepressed / switch
Feb 19^th, 2009, 11:18pm

Hi, im trying to create a switch function with a for structure to create a switch matrix. This is where im stuck:

Quote:

color c = 255;
int x;
int y;
int w;
int h;
void setup() {
  size(400,400);
  smooth();
  rectMode(CENTER);
}

void draw() {
  background(#1F45AA);
  for(int i = 40; i < 375; i = i+75) {
  for(int j = 40; j < 375; j = j+75) {
  button(i,j,50,50);   //This is the button with the for structure
  }}
}

void button(int tempx, int tempy, int tempw, int temph) { //This is the button function with parameters
  x = tempx;
  y = tempy;
  w = tempw;
  h = temph;
  strokeWeight(5);
  fill(c);
  rect(x,y,w,h);
}
void mousePressed() {
  if(c == 255 && mouseX <= x + w/2 && mouseX >= x - w/2 && mouseY >= y - h/2 && mouseY <= y + h/2) { //This line is supposed to constrain the mouse to fill only one instance of the array ... but it dont work...
    c = 0;
  } else {
    c = 255;
  }
}

When i remove the constrains i can switch all the buttons at once and it work! but when i use them in the mousePressed function none works...

here is the code without constrains:
color c = 255;
int x;
int y;
int w;
int h;
void setup() {
size(400,400);
smooth();
rectMode(CENTER);
}

void draw() {
background(#1F45AA);
for(int i = 40; i < 375; i = i+75) {
for(int j = 40; j < 375; j = j+75) {
button(i,j,50,50);
}}
}

void button(int tempx, int tempy, int tempw, int temph) {
x = tempx;
y = tempy;
w = tempw;
h = temph;
strokeWeight(5);
fill(c);
rect(x,y,w,h);
}
void mousePressed() {
if(c == 255) {
c = 75;
} else {
c = 255;
}
}

please help me fix it,
Odin

Something like this might be a little better..
Hope it works.. just typed it in the textarea

Button[] b;
void setup()
{
size(500,500);
b = new Button[20];
for(int i = 0; i < b.length; i++){
b[i] = new Button(0,i*25,75,20);
}
}
void draw()
{
background(0);
for(int i = 0; i < b.length; i++){
b[i].draw();
}
}

void mousePressed()
{
for(int i = 0; i < b.length; i++){
if(b[i].pressed()) break;
}
}

class Button
{
boolean on = false;
int x, y, w, h;
Button(int _x, int _y, int _w, int _h)
{
x = _x;
y = _y;
w = _w;
h = _h;
}
void draw()
{
fill(75);
if(on){
fill(255);
}
rect(x,y,w,h);
}
boolean over()
{
return mouseX>=x && mouseX<x+w && mouseY>=y && mouseY<y+h;
}
boolean pressed()
{
if(over()){
on = !on;
return true;
}
return false;
}
}

I'm bored, therefore I program

Nice, it work but ill have to make some changes in there.. and i dont understand well what you done with the boolean over and all those things... an other thing is that you are not using rectMode in your code and it makes the thing even more difficult to change.. But, it kinda help me.. but there is no other way to create a toggle function easier than this in a class?????
i tried to create a simple button function and add a void mousePressed with it so i can toggle the value but it wont work.... anyway,

Thanks you ALOT for everything,
Odin
