I have a bunch of objects in an array in Greenfoot, when act(loop that keeps game going) runs I need to get some information about the array from within the object that belongs to it. What ways are there for getting information about the array from within the objects it contain?
1 Answer
Store a reference in the object to the list. For example:
class MyObject {
List owner;
// ...
public void setOwner(List owner) { this.owner = owner; }
}
In this way, you can access to the owner list from any method in MyObject. When you add the object to the list, don't forget to call the "setOwner" method.

Will work. But I have to wonder, if you require info about a container in the contained elements, there might be a design issue.
