MousePressed on draw. I want just one event.
May 10th, 2010, 7:54am  
I have this code , where if you press the image on the top -left corner , it takes you to processing.com.



Buut the thing is , like it is on draw it  opens many links ,


is there a way to make the mousepressed only act once ???


heres the code :

you need an image called  "javi_img_01.jp" in your folder , just rename any image and put it in the sketch folder.

thanx !!!

Code:
int borde = 20;
int hoover = 5;
int borde_hoover;
PImage b;


void setup(){
  size(600,600);
  smooth();
  background(255);
  b = loadImage("javi_img_01.jpg");
}

void draw(){
  background(255);
  drawR_1(width/2-borde,width/4,height/4);
  drawR_2(width/2-borde,width-width/4,height/4);
  drawR_3(width/2-borde,width/4,height-height/4);
  drawR_4(width/2-borde, width-width/4,height-height/4);
}

void drawR_1( int tamanio, int rx_pos, int yx_pos ){
  fill (0);
  imageMode(CENTER);
  noStroke ();
  if(mouseX > borde_hoover && mouseX < width/2-borde_hoover && mouseY > borde && mouseY < height/2-borde_hoover ){
    tamanio += hoover ;
  } else {
    tamanio -=hoover ;
  }
  image (b , rx_pos, yx_pos , tamanio, tamanio);
   
   
   // here is link 
    
    if (mouseX > borde_hoover && mouseX < width/2-borde_hoover && mouseY > borde && mouseY < height/2-borde_hoover && mousePressed == true ){
	 link("http://processing.org"); 
}
  
    
 
    

}


void drawR_2 ( int tamanio, int rx_pos, int yx_pos ){
  fill (0);
  rectMode ( CENTER);
  noStroke ();
  if (mouseX > width/2+borde_hoover && mouseX < width-borde_hoover && mouseY > borde && mouseY < height/2-borde_hoover ){

    tamanio += hoover ;
  }
  else{
    tamanio -=hoover ;

  }

  rect ( rx_pos, yx_pos , tamanio, tamanio);
}

void drawR_3 ( int tamanio, int rx_pos, int yx_pos ){
  fill (0);
  rectMode ( CENTER);
  noStroke ();
  if (mouseX > borde && mouseX < width/2-borde_hoover && mouseY > height/2 && mouseY < height-borde_hoover ){

    tamanio += hoover ;
  }
  else{
    tamanio -=hoover ;
    
 

  }

  rect ( rx_pos, yx_pos , tamanio, tamanio);
}

void drawR_4 ( int tamanio, int rx_pos, int yx_pos ){
  fill (0);
  rectMode ( CENTER);
  noStroke ();
  if (mouseX > width/2+borde_hoover && mouseX < width- borde && mouseY > height/2+borde_hoover && mouseY < height-borde_hoover ){

    tamanio += hoover ;
  }
  else{
    tamanio -=hoover ;

  }

  rect ( rx_pos, yx_pos , tamanio, tamanio);
}

fixed it.

moved the mousedpressed function out of the drawrec function and this new function :


Code:
void mousePressed() { 
    if (mouseX > borde_hoover && mouseX < width/2-borde_hoover && mouseY > borde && mouseY < height/2-borde_hoover && mousePressed == true ){
  link("http://processing.org");
}



so this would be the new code :


Code:
int borde = 20;
int hoover = 5;
int borde_hoover;
PImage b;


void setup(){
  size(600,600);
  frameRate (12);
  smooth();
  background(255);
  b = loadImage("javi_img_01.jpg");
}

void draw(){
  background(255);
  drawR_1(width/2-borde,width/4,height/4);
  drawR_2(width/2-borde,width-width/4,height/4);
  drawR_3(width/2-borde,width/4,height-height/4);
  drawR_4(width/2-borde, width-width/4,height-height/4);
}

void drawR_1( int tamanio, int rx_pos, int yx_pos ){
  fill (0);
  imageMode(CENTER);
  noStroke ();
  if(mouseX > borde_hoover && mouseX < width/2-borde_hoover && mouseY > borde && mouseY < height/2-borde_hoover ){
    tamanio += hoover ;
  } else {
    tamanio -=hoover ;
  }
  image (b , rx_pos, yx_pos , tamanio, tamanio);
   
   
  
}


void drawR_2 ( int tamanio, int rx_pos, int yx_pos ){
  fill (0);
  rectMode ( CENTER);
  noStroke ();
  if (mouseX > width/2+borde_hoover && mouseX < width-borde_hoover && mouseY > borde && mouseY < height/2-borde_hoover ){

    tamanio += hoover ;
  }
  else{
    tamanio -=hoover ;

  }

  rect ( rx_pos, yx_pos , tamanio, tamanio);
}

void drawR_3 ( int tamanio, int rx_pos, int yx_pos ){
  fill (0);
  rectMode ( CENTER);
  noStroke ();
  if (mouseX > borde && mouseX < width/2-borde_hoover && mouseY > height/2 && mouseY < height-borde_hoover ){

    tamanio += hoover ;
  }
  else{
    tamanio -=hoover ;
    
 

  }

  rect ( rx_pos, yx_pos , tamanio, tamanio);
}

void drawR_4 ( int tamanio, int rx_pos, int yx_pos ){
  fill (0);
  rectMode ( CENTER);
  noStroke ();
  if (mouseX > width/2+borde_hoover && mouseX < width- borde && mouseY > height/2+borde_hoover && mouseY < height-borde_hoover ){

    tamanio += hoover ;
  }
  else{
    tamanio -=hoover ;

  }

  rect ( rx_pos, yx_pos , tamanio, tamanio);
}





void mousePressed() { 
    if (mouseX > borde_hoover && mouseX < width/2-borde_hoover && mouseY > borde && mouseY < height/2-borde_hoover && mousePressed == true ){
  link("http://processing.org");
}

}

By convention with something like a link or button that's pressed with a mouse you perform the action on mouse release.  That way if the user presses down but changes their mind about following the link or pressing the button they can move the mouse away and release without invoking the action...

allright , yres its true.

so should i just change the function void mousePressed(){  for

void mouseReleased (){

?



Or should i do something else ?

EDIT :


Mousereleased , is just not working if i just change it instead of mousePressed , any ideas ?
