your problem is here
Code:

 class mouseFlw{
 float xpos;
 float ypos;
 
 mouseFlw(float xx, float yy){
 xpos=xx;
 ypos=yy;
 }  
}
 
void delayXY(float posX, float posY, float friction){
 float diffX= xpos - posX;
 if(abs(diffX)>1){
  xpos -=diffX/friction;  
 }
 float diffY= ypos - posY;
 if(abs(diffY)>1){
  ypos -=diffY/friction;  
 }
rect(xpos,ypos,30,30);  
} 
 

in function delayXY you are referring to (I assume) the ypos in the object. Yet you've passed no instance of the object into the function from which to work. What you are looking for should be:

OBJECTNAME.ypos;

That should return the ypos for that object only, where OBJECTNAME is the instance name of the object you've passed it. It is a common early OOP mistake :]

yes,

i figured out the problem:

here is my latest code:

-------------------------------------
//a very simple delay movement
mousesquare ms1,ms2,ms3,ms4;

void setup(){
size(400,400);
rectMode(CENTER);
fill(120);
noStroke();
framerate(60);
ms1=new mousesquare(100,100);
ms2=new mousesquare(100,100);
ms3=new mousesquare(100,100);
ms4=new mousesquare(100,100);
}
//for loop,
void draw(){
 background(200);
 ms1.display();
 ms2.display();
 ms3.display();
 ms4.display();
 ms1.moveto(mouseX,mouseY,2);
 ms2.moveto(mouseX,mouseY,5);
 ms3.moveto(mouseX,mouseY,10);
 ms4.moveto(mouseX,mouseY,20);
}

class mousesquare{
float xpos;
float ypos;

mousesquare(float xx,float yy){
  xpos=xx;
  ypos=yy;
}


void moveto(float tarX,float tarY,int friction){
  float difx=tarX-xpos;
 if(abs(difx)>1.0){
  xpos +=difx/friction;
 }
 float dify=tarY-ypos;
 if(abs(dify)>1.0){
  ypos +=dify/friction;
 }
}

void display(){
  rect(xpos,ypos,30,30);
 }
}
-------------------------

the mistake is i void the display() outside of the object class, that is why the xpos and ypos is not defined so that cannot be access.

ok, good lesson finally. thanks to mflux for enlightening

hi flight404,

wow! i don't expect you to answer

i m a big fans of yours. i love your version 7 which i find is the sexiest website i ever seen.

anyway, i kind of study your version 8 website and have no idea how you manage to get the processing running fullscreen in browser still make it run smoothly. how did you do that?? and did you splited up processing into small pieces so that it loaded faster or is just 1 .jar file to process the entire website??

and how to do the loading...xx% thingy?? sorry that i have so many questions for you but i just the beginner scripter here so i guess i got a lot more to learn.

but thanks for helping.

sooon

i really speechless...

hahahaha. i was cheated by your processing stuff in it. hmm... ok. now i know.

yes i started to enjoy like those day when i started to learn actionscript in flash. and now i make myself try to learn a thing everyday. so that 3 months later i can already build stuff with it.
