Get Edges

In the last chapter we checked if a unit's (x, y) point was within a rectangle (the Dragon's breath). But units aren't really points - they have their own areas.

So we're going to check if a dragon's body (a rectangle) is within the fire (also a rectangle). The image below contains an example of fire breath hitting a dragon.

Later we'll write the overlap method, but first we'll just write a method to find the edges of a rectangle.

Assignment

We changed the coordinates themselves to be private by adding two underscores to them. We now need to write getter methods to access them.

Complete the following methods:

1. get_left_x(): Returns the leftmost (smallest) x value
2. get_right_x(): Returns the rightmost (largest) x value
3. get_top_y(): Returns the topmost (largest) y value
4. get_bottom_y(): Returns the bottom-most (smallest) y value

Remember that we're working with a standard Cartesian plane.

We will explain the __repr__ method later, don't worry too much about it.

Tips

You may find Python's built-in min and max functions useful. For example, min(3, 7) returns 3, and max(3, 7) returns 7.
