Simple Particle Simulation with SDL2

This program is a simple particle simulation using the SDL2 library. It initializes a screen using SDL, creates a swarm of particles, and updates their positions and colors in a game loop until the user decides to quit.

Prerequisites

• A C++ compiler supporting C++11 or later.
• SDL2 library installed on your system.

Building and Running

To build and run the program, follow the steps below:

1. Navigate to the project directory.
2. Run the build command (this may vary depending on your build system and platform).
3. Execute the resulting binary.

Example with g++ on Linux

g++ -std=c++11 -o ParticleSimulation main.cpp Screen.cpp Swarm.cpp Particle.cpp -lSDL2
./ParticleSimulation

Code Structure

• main.cpp: Contains the main function where the program starts. It initializes the screen, handles the game loop, updates particles, and draws them to the screen.
• Screen.cpp: Manages the screen initialization, updating, and event processing using SDL2.
• Swarm.cpp: Manages the swarm of particles, including their updating.
• Particle.cpp: Represents an individual particle and manages its properties and behavior.

Headers

• Screen.h: Header file for the Screen class.
• Swarm.h: Header file for the Swarm class.
• Particle.h: Header file for the Particle class.

Usage

Once the program is running, it will display a swarm of particles on the screen with changing colors. The user can quit the program by closing the window.
