Instances talking to each other
Feb 8th, 2008, 7:38pm  
Hi,

I'm playing with Dan Shiffman's basic particle system.

http://www.processing.org/learning/topics/simpleparticlesystem.html

I was each particle to be able to access the particles arrayList in the ParticleSystem Class, but am unsure how I should approach it.

I've tried passing the particles arraylist as a parameter to the particle, but only get syntax errors. Is there a way to access a parent class's variables?

Any tips?

If you want something shared throughout all instances of an object you can try playing with static members.

For example

class Thing{
 static float num = 0;
}

"num" now exists only once, in all instances of Thing.
