dear all,

i begin to enjoy processing

how possible for processing to actually call another processing file into current file.

i tends to use flash as the reference of development.

in flash we can call external .swf file into 1 main .swf file.

so that the main .swf file is not as heavy as it is. so i m just wondering if this is possible in processing.

i see some of the expert out there actually have some "loading...xx%" in their processing file. can some body show me how to do that too?? thanks in advance. processing rock!

If you know OOP well, you can write all your programs in such a way so as to code processing as if you were doing flash, having multiple "movie files" in this case, processing code, and be able to execute them at will. It's a bit tricky, but here's how it's done.


Create a master template class from which all other "programs" will inherit. In this case, let's name it "client":

Code:

class Client(){
  Client(){}
  void draw(){}
  void mousePressed(){} 
  //callbacks etc
}
 

Next, create an array space for these clients

Code:

Vector clients;
 

You can add clients via Vector method add()

Code:

clients.add(MyClient());
 

And in your draw(), cycle through your clients:

Code:

for(int i=0;i<clients.size();i++){
  Client currentClient = (Client)clients.get(i));
  currentClient.draw();
}
 

You can also use the same technique to implement callbacks, such as:

Code:

void mousePressed(){
  for(int i=0;i<clients.size();i++){
    Client currentClient = (Client) currentClient.get(i);
    currentClient.mousePressed();
  }
}
 

Now that you have this framework set-up, you can write any type of processing code within this framework, and you can run everything simultaneously, selectively, however you wish. For example:

Code:

class Flux extends Client{
  Flux(){
  }
  void draw(){
    ellipse(50,50,100,100);
  }
}
 

Now I just made a class that is share-able between all others. In fact, I can copy and paste entire processing sketches to fit within this framework, then run them concurrently.

Enjoy!!
