flash convert, Dynamic reference.
Mar 17^th, 2006, 6:23pm

Hi i'm new to processing and need some guidance.
I have created a class and made several instances of it.
In the draw function I want to call a function <.update()> from each one. In flash I have been able to put this in a for loop and used what I think is called array access notation to reference the instances.
Example code

MyClass obj0 = new Myclass();
MyClass obj1 = new Myclass();
MyClass obj2 = new Myclass();

void draw() {
for(int i = 0; i < 3; i++) {
this["obj" + i].update();
}
}

How would i do this in processing? The code above wont run, i have tried replacing this[...] with MyClass[...] but that’s it i’m out of ideas.
Any suggestions?

this should work:
Code:


MyClass[] obj=new MyClass[3];
void setup(){
 for(int i = 0; i < 3; i++) {
    obj[i]=new MyClass();
  } 
}
void draw(){
 for(int i = 0; i < 3; i++) {
    obj[i].update();
  } 
}

You must create a new array of objects of the MyClass class. At the setup methode you fill this array with three new objects.
