Confused on why we put get and took out const when making the tower class overridden.

I am confused on why we took out the const and put get in the override when we changed the Tower.cs. Originally the code was as below:

      private const int _range = 1;
      private const int _power = 1;
      private const double _accuracy = .75;

Then the code was changed to the following in order to override.

      protected virtual int Range { get; } = 1;
      protected virtual int Power { get; } = 1;
      protected virtual double Accuracy { get; } = .75;

Can someone explain why these changes happened this way?

It looks like you answered your own question.

The answer is "in order to override". You can only override properties that are defined in the base class as "virtual". And adding the "get" makes it a property instead of a field, which is also necessary to override. You can't override fields.

Ah that's why. I didn't realize you couldn't override fields.
