Talk:Object Sets/@comment-25353245-20140904234855

most of it shows how to use set, but I would suggest that to help people understand why they should learn that. For example, explaning how sets can be usefull to create a classification system for a level, so you can for example manipulate types of different trees, as sets like: [object set: All Trees], [Object set: palm trees], and so on, and be able to intersect palm trees with All trees in the game, which create sort of a hierarchy tree

Another example to illustrate that would be to think about the animal kingdom classification system: all dogs intersects animals, cats intersect animals, but both do not intersect chimps, for example
