How and what do you use it for?

getNeighbours()?
As it says in the documentation:
Return the neighbours to this object within a given distance. This method considers only logical location, ignoring extent of the image. Thus, it is most useful in scenarios where objects are contained in a single cell.
All cells that can be reached in the number of steps given in 'distance' from this object are considered. Steps may be only in the four main directions, or may include diagonal steps, depending on the 'diagonal' parameter. Thus, a distance/diagonal specification of (1,false) will inspect four cells, (1,true) will inspect eight cells.
You call it in the same way you call any method. The return is a List; you should add an import statement for List at the top of your class:
Then you can do:
You can check if a list is empty using "isEmpty()":
You can do something for each actor in the list using a "for" loop:
... and so on.
import java.util.List;
List neighbours = getNeighbours(1, true, null);
if (neighbours.isEmpty()) {
// do something - code here
}
for (Object o : l) {
Actor a = (Actor) o;
// do something here!
}
