Sprite Physics Simulation

Overview

This project simulates physics interactions between sprites (squares and circles) on a terminal interface using ncurses. Sprites can be dynamically added, removed, and manipulated using commands sent via a named FIFO pipe.

The simulation supports:

• Collision detection and response.
• Gravity and restitution.
• Random sprite generation.
• Real-time command handling.

Features

• Dynamic Sprite Addition: Add circles or squares with customizable properties.
• Collision Detection: Handles collisions between sprites with realistic velocity exchanges.
• Customizable Parameters: Adjust gravity and coefficient of restitution.
• Interactive Commands: Manage the simulation through a FIFO pipe or provided shell script.
• Random Sprite Generation: Generate multiple random sprites.

Prerequisites

• C++ compiler (e.g., g++)
• ncurses library
• UNIX-like operating system (for FIFO pipes)

Compilation and Execution

1. Compile the program:

   g++ physcii.cpp -o physcii -lncurses -pthread

2. Run the program:

   ./physcii

3. Open a separate terminal to send commands:

   ./controller.sh

Commands

The simulation listens for commands through a FIFO pipe (/tmp/physics_fifo). The following commands are supported:

• Add a sprite:

  add <shapeType (C/S)> <Name> <Size> <X_position> <Y_position> <X_velocity> <Y_velocity>
  

  Example:

  add C Circle1 5 10 10 2 -3
  

• Remove a sprite:

  remove <Name>
  

  Example:

  remove Circle1
  

• Set gravity:

  set gravity <value>
  

  Example:

  set gravity 2
  

• Set coefficient of restitution:

  set coe <value>
  

  Example:

  set coe 0.8
  

• Generate random sprites:

  random <count>
  

  Example:

  random 10
  

• Clear all sprites:

  clear
  

• Exit the command script:

  exit
  

Shell Script

The provided controller.sh simplifies interaction with the simulation. Ensure it is executable:

chmod +x controller.sh

Run the script:

./controller.sh

Controls During Simulation

• Press q or Q to quit the simulation.

Code Structure

• physics_simulation.cpp: Main simulation logic.
• command_script.sh: Script to send commands to the simulation via FIFO.
