changed syntax for constructors??
Dec 3rd, 2007, 9:33pm  
hi,
i tried to write a class and always got an error message

unexpected token: (

with the row of my constructor highlighted

after a while i tried an example from the processing book
and it didn`t work too.
i dont think that i made a syntax error,
has there anything changed in version 0135?

thanks for every answer

I seriously doubt anything has changed.

You'll need to post an example piece of code for us to be able to help any further.

hi Johng,

thanks for answering.
here`s the code

class LED{
 
 float x,y;
 
 int i;
 int diameter;
 int transparency = 255;
 int on,off;
 
 color light = color(on,transparency); ;
 color dark = color(off); ;
 
 boolean over = false;
 boolean pressed = false
   
 LED (float xp, float yp, int d, int an, int aus){
   
   x = xp;
   y = yp;
   diameter = d;
   on = an;
   off = aus;
 }
 
 void update(){
   
   if((mouseX >= x-diameter) && (mouseX <= x+diameter) &&
      (mouseY >= y-diameter) && (mouseY <= y+diameter){
       
        over = true;
   }
   else{over = false;}
 }
 
 void press(){
   
   if(over = true){
     
     pressed = true;
     return true;
   }
   else{return false;}
 }
 
 void display(){
       
   if(pressed = true){
     fill(light);      
     for(i= 255; i>0; i--){
       transparency = i;
     }
   }
   else{fill(dark);}
   
   noStroke();
   ellipse(x,y,diameter,diameter);
 }
}
   
 
maybe there are a lot of errors i´m relativ new to processing

Just a missing semi-column :

boolean pressed = false
                       ^^
 LED (float xp, float yp, int d, int an, int aus){
