2,201 PointsWhy is the code `` location = invader.Location; needed `` when earlier code had set the Location field to location?
In 3:41 of the video, the code already has
invader.Location = location;
before adding
location = invader.Location;
The presenter says this second statement "gets the location from the invader and sets it back into the local variable location." I am not quite clear on why this second statement is needed if the invader.Location = location; already exists. Per the video on Fields (link)[https://teamtreehouse.com/library/fields] the first statement already used dot notation to allow us to access the Location field and it was set to location.
Am I missing something?
