Assignment 7: “Pokémon, The Level-Up Update”

Objectives

• Read and understand all of the Pokémon source code from Lecture 7.
• Implement a Menu that appears during the player Pokémon’s level up that shows, for each stat, ‘X + Y = Z’, where X is the starting stat, Y is the amount it’s increased for this level, and Z is the resultant sum. This Menu should appear right after the “Level Up” dialogue that appears at the end of a victory where the player has indeed leveled up.

Getting Started

Download the distro code for your first game from https://cdn.cs50.net/games/2019/x/assignments/7/assignment7.zip and unzip assignment7.zip, which should yield a directory called assignment7.

Then, in a terminal window (located in /Applications/Utilities on Mac or by typing cmd in the Windows task bar), move to the directory where you extracted assignment7 (recall that the cd command can change your current directory), and run

cd assignment7

Next-Level

Welcome to your seventh assignment! This week’s code will probably be the most complicated we’ll look at during the semester, but the assignment itself is fairly small in comparison; you will, however, need to know how many of the pieces work and fit together in order to accomplish the task ahead.

Your goal this assignment:

• Implement a Menu that appears during the player Pokémon’s level up that shows, for each stat, ‘X + Y = Z’, where X is the starting stat, Y is the amount it’s increased for this level, and Z is the resultant sum. This Menu should appear right after the “Level Up” dialogue that appears at the end of a victory where the player has indeed leveled up. The area where most of this will take place is the TakeTurnState, specifically in the :victory() function, where the actual detection of a level up takes place. Ordinarily, just a BattleMessageState gets pushed onto the StateStack, but we’ll need to go a step further and push an additional Menu in order to accomplish what we’re after. This Menu should not have a cursor like the other Menu we’re used to seeing (in the BattleMenuState!), so you’ll need to customize the Selection class a little bit in order to take a boolean value to turn the cursor on or off as needed (defaulting to true if needed to preserve the behavior of the Menu in the BattleMenuState). Note that the :levelUp() function in the Pokemon class returns all of the stat increases we need in order to display things properly, so be sure to use those returned values when creating the Menu! As long as you get a proper grasp on the Selection, Menu, and StateStack classes, this assignment should be relatively straightforward in comparison to the complexity of this week’s code as a whole!

How to Submit

1. If you haven’t already, install Git and, optionally, install submit50.

2. Using Git, push your work to https://github.com/me50/USERNAME.git, where USERNAME is your GitHub username, on a branch called games50/assignments/2019/x/7 or, if you’ve installed submit50, execute
