Boids-Unity

A simple 3D Boids simulation in Unity demonstrating flocking behavior.

Overview

This project implements a basic Boids algorithm in Unity. Each agent (Boid) follows three main rules:

1. Separation: avoid crowding neighbors
2. Alignment: align velocity with nearby agents
3. Cohesion: move towards the average position of nearby agents

Boids also avoid obstacles within a set radius, and movement is handled with smooth rotation and velocity clamping.

How It Works

• Boid Controller (BoidController.cs)
  Controls individual Boid behavior. Applies separation, alignment, cohesion, and obstacle avoidance. Updates position and rotation each frame.

• Camera Controller (CameraController.cs)
  Syncs up the editor camera with the game.

• Physics-Based Vision
  Each Boid uses Physics.OverlapSphere to detect neighbors and obstacles within a vision radius.

• Steering
  Uses Quaternion.Slerp to rotate smoothly toward target directions calculated from the flocking rules.

• Velocity and Movement
  Forces are applied per frame, then velocity is clamped and drag is applied to smooth movement.
