Capstone Project: Snake Game

Overview

This repo includes the Capstone project in the Udacity C++ Nanodegree Program.The source code has been heavily adapted from the provided starter code located at (Udacity's repo)[https://github.com/udacity/CppND-Capstone-Snake-Game].

Introduction:

Once the game starts it creates the Game, Controller, and Snake objects, then game continues to loop through each component and simultaneously grabs input from the user, Controller, later it updates the state of the Game, and graphically renderers the state of the game, Render. This is the high level overview of the logic flow.

Additional Functionality

When the game is launched, the user is first greeted with a warm welcome message and also the game detectes system platform which the user is running the game on.

Then the user is asked for the select a level. There are three different levels which user can start with: Easy (E), Medium (M) and Hard (H). Once the user has selected a particular level the snake speed is set to a particular value and game continues. The game board launches after the user provides a valid level and the user is able to play the game by moving the snake around with the arrow keys.

Following image shows the output on the terminal, when the game is launched in all different levels.

Dependencies for Running Locally

cmake >= 3.7
- All OSes: click here for installation instructions
make >= 4.1 (Linux, Mac), 3.81 (Windows)
- Linux: make is installed by default on most Linux distros
- Mac: install Xcode command line tools to get make
- Windows: Click here for installation instructions
SDL2 >= 2.0
- All installation instructions can be found here
- Note that for Linux, an apt or apt-get installation is preferred to building from source.
gcc/g++ >= 5.4
- Linux: gcc / g++ is installed by default on most Linux distros
- Mac: same deal as make - install Xcode command line tools
- Windows: recommend using MinGW

Basic Build Instructions

Clone this repo using https://github.com/vrushabhdesai/Capstone_Project_Snake_Game.git
Make a build directory in the top level directory: mkdir build && cd build
Compile: cmake .. && make
Run it: ./snakeGame.

Criterias which support the Capstone Project:

Criteria	Description
Loops, Functions,I/O	The user has the option to select the starting level which sets the speed of the snake. A Game class member function `UpdateStartSpeed` is called and this member function encapsulates the Game's private data member `snake` and calls the Snake class member function `SetStartingSpeed`.
The project accepts user input and processes the input	User Main Manu is the interactive interface with the game. GameManger.h class
The project uses Object Oriented Programming techniques.	To meet this requirement, a `Platform` class was created in `game.h` to hold information about the system platform.
Classes use appropriate access specifiers for class members.	The class uses member initialization lists and the member functions getPlatform and printPlatform to fetch and printout the user's detected system platform.
Classes abstract implementation details from their interfaces	The C++ Guide by Google was used to for any needed documentation. An example can be found within `game.h` (Platform class member funtions) above the function declaration of `getPlatform` where a simple comment is used to describe what the function does.
