CPPND: Capstone Shooter game

This is my sumbition for udacity capstone project in c++. it's a simple shooter game made with sdl. your goal is to have the highest score possible. my personal best is 62. each time you kill an ennemy. 2 ennemies will spawn

Controls

• arrow keys to move and change shooting direction while moving.
• hold space to charge your shot. release space to shoot.
• press r to restart

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
4. Run it: ./game.

Loops Function I/O

criteria	status	commentary
C++ functions and control structures.	✔️
The project reads data from a file and process the data, or the program writes data to a file.	✔️	loading textures and font and rendering it
The project accepts user input and processes the input.	✔️	user input is accesesd through sdl event system then dispatch then processed by player & game class through my own event system

Object Oriented Programming

criteria	status
The project uses Object Oriented Programming techniques.	✔️
Classes use appropriate access specifiers for class members.	✔️
Class constructors utilize member initialization lists.	✔️
Classes abstract implementation details from their interfaces.	✔️
Classes encapsulate behavior.	✔️
Classes follow an appropriate inheritance hierarchy. & Derived class functions override virtual base class functions.	✔️
Overloaded functions allow the same function to operate on different parameters.	✔️
Templates generalize functions in the project.	✔️

Memory Management

criteria	status
The project makes use of references in function declarations.	✔️
The project uses destructors appropriately.	✔️
The project uses scope / Resource Acquisition Is Initialization (RAII) where appropriate.	✔️
The project follows the Rule of 5.	✔️
The project uses move semantics to move data, instead of copying it, where possible.	✔️
The project uses smart pointers instead of raw pointers.	✔️

Concurrency

criteria	status
The project uses multithreading.	✔️
A promise and future is used in the project.	✔️
A mutex or lock is used in the project.	✔️
A condition variable is used in the project.	✔️

multithreading is used for infinite procedural props generation. It's done asynchrounously when the camera reveal space where prop. A procedural world generation task is then pushed to the thread pool managing all thread synchronisation mechanism.
