How does thos method work, when more than one object are intersecting? Is one of them choosen random? I have to know that because that's maybe the problem, why my code doesn't work.

getOneIntersectingObject()
The method getOneIntersectingObject always returns a randomly chosen object from the list. (But it's always the same one, when the object still intersects)
Why don't use the method getIntersectingObjects()?
there you get a List of all that are intersecting it! :)
I don't know, how to deal with a list. But now I know, why my code doesn't work. How can I read out the lines of a list to get the objects?
To handle with a list, you first has to import the List-class, by writing
import java.util.List;
over your class!
Then you can get the objects in the List by writing:
Then you've got more possibilities to go through the list. You could use the methods of the List-class. Or you use the 'for'-loop by writing:
The for-loop is repeated for each element of the List.
The first time it goes through the loop, in 'classObject ' is the first object of the List saved,
by the second go through, the second object of the List, etc.... :)
1 | List<ClassName> list_Objects=getIntersectingObjects(ClassName.class); |
1 2 3 4 | for(ClassName classObject : list_Objects){ // Code, what you want to do with the objects} |
Thank you!
