229,783 PointsThe Rest option allows you to heal.
Assuming you are using (and have not modified) the code from the final video, then if it's your turn, your choices are "[A]ttack, [R]est, [Q]uit". If you choose "R" (rest), and the current hit points are less than the base points, your character will heal by one point.
If a monster is attacking, you should have the option "Dodge? Y/N". If you choose "Y" your character will attempt to dodge. A random value will be chosen by the program to determine if you are successful, with a probability of 1 out of 3.

36 Pointsokej, I want Rest inside a class named healer.py how can i change that?
Steven Parker
229,783 PointsDid you add import healer to game.py?

36 Pointsupdated Steven. still have problem in file game.py: AttributeError: 'Character' object has no attribute 'rest' need to make game.py understand the object is inside heal.py
Steven Parker
229,783 PointsYou may need much more extensive changes to make this work.
I didn't see any problem recognizing the new heal.py file. But there are several other more serious issues.
For one thing, in game.py, when the player choses the "R" option, there is this code:
self.players.rest()
But the Game object, which "self" refers to here, has no "players" property. Now it does have a "player" property (no "s"), but the player contains a Character object, and that object no longer has a "rest" method (It did in the original code).
Even if you were to invoke Heal.rest(), you would still have other issues. The code in that method refers to two properties, "hit_points" and "base_hit_points", but neither of those properties exist in the Heal class. And if you added them to the class, the method will still not improve the health of the Character object. If you still want to improve the player health, it's not clear to me why removing the method from the Character object would be desirable, but it will certainly require a lot more code.
This might be a good time to re-think your objectives for making the changes. Perhaps what you want to accomplish can be done in a simpler way.

36 Pointscan you tell me how i can make it easier?
Steven Parker
229,783 PointsI still have no clue what you are trying to accomplish.
Tim rkan
36 Pointsi want rest (R) to be a own class. rest will be inside heal.py insted of character.
Steven Parker
229,783 PointsYou misunderstood me .. I meant what did you want to make different about the way the game behaves?
Making changes that do not affect program behavior is called refactoring, and has no value unless it makes the code smaller, faster, or more maintainable. What you are suggesting would do the opposite.
Tim rkan
36 PointsI only want to put rest inside a own class. its about learning :)
Steven Parker
229,783 PointsYou'll get much better value from your learning if you concentrate on "best practices". What you are talking about doing would actually violate many best practices. It's like a student of auto mechanics asking another student to "help me replace the gas tank with a tin washtub mounted on the roof."
I might help you with some custom projects if I thought they would be a positive reinforcement to your course learning, but I'm going to let you continue this particular task on your own.
But good job on learning how to format your code with Markdown. And when lots of code is involved, an even better way to share it is to make a snapshot of your workspace and post the link to it here.
Best of luck, and happy coding.

Python Web Development Techdegree Graduate 49,610 PointsCould you show us the code you have thus far? Or Share your Workspace if you wrote your code in it?
Its hard to say how to approach something, the less I know what code you have in-place the more assumptions I have to make. :)
