Go-RayLib-Boids

Go RayLib: Boids

An implementation of Boids using Go and the RayLib bindings.

Running the Project

Once you have an executable, the functionality of the program is entirely determined through the config.yaml file. The config file give in this repository has some good defaults, but feel free to play around with these! The config parameters are:

• WindowWidth: The width of the window, in pixels
• WindowHeight: The width of the window, in pixels
• NumBoids: The number of boids to spawn
• BoidVelocity: The target velocity of each boid
• BoidVision: The distance that boids can see, in pixels --- larger visions make for more stable emergent flocks
• BoidSeparationOptimalProximity: The proximity measure boids aim for --- a proximity of 1.0 is as close as possible
• BoidSeparationCoefficient: How strongly boids weight Separation --- Determines how separated boids should be
• BoidAlignmentCoefficient: How strongly boids weight Alignment --- Determines how aligned boids should be, makes boids fly in the same direction
• BoidCohesionCoefficient: How strongly boids weight Cohesion --- Determines how cohesive boids should be, makes boids steer towards other boids
• NumWorkers: The number of worker goroutines to use --- more go routines means faster frames, but requires more resources
• RandomSeed: The random seed used for initialization --- use 0 for a random seed based on the timestamp

Building the Project

• Ensure you have installed the requirements for RayLib, as per the raylib-go README.
• Ensure you have Go 1.23 or later installed (although earlier versions may work, just change the go.mod file first).
• Clone the repository.
• Run go build ., followed by ./Go-RayLib-Boids.
  • The first build may take some time, as you will build the RayLib backend too. Future builds will be much faster!
