Dragons

In "Age of Dragons" there are Orcs, Humans, Goblins, Dragons, etc. All of those different creatures are called "units". The only thing specific to a unit is that it has a position on the game map (x and y coordinates) and a name.

Dragons are a specific type of unit. They can breathe fire in a large area dealing damage to any units touched by its fiery blaze.

The Game Grid

Our game map is just a Cartesian plane.

Example of Fire Breath

The example above uses a __fire_range of 1 centered at (1, 1).

Assignment

Complete the following methods:

Complete the unit's in_area method. It accepts an "area" represented by four coordinates: x_1, y_1, x_2, and y_2. The coordinates x_1 and y_1 represent the bottom-left corner, while x_2 and y_2 represent the top-right corner.
1. Determine if the unit is within the given area by using the unit's position coordinates pos_x and pos_y.
2. Return True if the unit's position falls inside or on the edge of the rectangle. Otherwise, return False.
Complete the dragon's breathe_fire method. It causes the dragon to breathe a swath of fire at the target area.
1. The target area is centered at (x, y). The area stretches for __fire_range in both directions inclusively.
2. Iterate over each unit in the units list, and check if the unit is in the area. If it is, add it to a new list that keeps track of the units hit by the blast.
3. Return the list of units hit by the blast.
