Dragon Area

Our Unit class has its simple version of in_area - it just checks if the center point of the unit is within the given area. But the Dragon is a big creature, and it doesn't make sense to check if a single point is within the area. So, we'll use a hit box instead!

This is the current behavior:

We want to change it so that a dragon is within an area if its hit box overlaps with it:

Since Dragon is a child class of Unit, it can override the in_area of the Unit class with its own behavior. Yay polymorphism! The Dragon still acts like a Unit (has an in_area method), but it has its own implementation.

Assignment

1. Complete the Dragon's constructor. See the tips below if you need help.
   1. Call constructor of the Unit class with the provided parameters
   2. Set the dragon-specific parameters as instance variables
   3. Create a new private __hit_box member. It's a Rectangle object representing the dragon's hit box.
2. Override the in_area method in the Dragon class:
   1. Create a new rectangle object with the given corner positions.
   2. Use the rectangle's overlaps method to check if the Dragon's self.__hit_box is inside it, and return the result.

The given pos_x and pos_y for any unit is the center point of that unit!

Tips

• The super() function allows you to call methods of a parent class.
• To calculate the Dragon's hit box:
  • x1 should be the dragon's pos_x (center x) minus half of the dragon's width.
  • y1 should be the dragon's pos_y (center y) minus half of the dragon's height.
  • x2 should be the dragon's pos_x (center x) plus half of the dragon's width.
  • y2 should be the dragon's pos_y (center y) plus half of the dragon's height.
