Snake Game using libsdl2

Extended snake game to support custom maps and ability to create maps using tilemaps.

What's new?

• You can now create custom maps for the game.
• The map is saved in a text file.
• The map is a 32x32 grid of elements.
• Each element in the map is a 0 or 1 which represent a block of a maze and blank space respectivly.
• See running instructions for steps on how to load a custom created map.
• The map directory contains a couple of example maps. If no map is specefied the game will load map.map from map directory by default.
• If no map is specefied normal game will start without any maze.

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

1. Clone this repo.
2. Make a build directory in the top level directory: mkdir build && cd build
3. Compile: cmake .. && make

Running

1. Run it: ./SnakeGame.

2. You can specify a map file using -m flag and spcefiy a .map file.

   Example: ./SnakeGame -m ../maps/map2.map

Rubric points covered

Point	is Covered
The project demonstrates an understanding of C++ functions and control structures.	yes
The project reads data from a file and process the data, or the program writes data to a file.	yes [map is loaded from a file saved in disk]
The project accepts user input and processes the input.	yes [accepts user input for map file path]
The project uses Object Oriented Programming techniques.	yes
Classes use appropriate access specifiers for class members.	yes [each member is marked explicitly in map class in map.h]
Class constructors utilize member initialization lists.	yes [map path is passed using initializer list]
Classes encapsulate behavior.	yes [map class encapsulates all map related behavior]
The project makes use of references in function declarations.	yes [renderer is passed using reference]
The project uses move semantics to move data, instead of copying it, where possible.	yes [std::move is used to move an rvalue in game.cpp]
