SFML-Boids

Implementation of Craig Reynold's Boids in C++11 with SFML2. Features placeable boids, scatter mode, predators, zooming and multithreading (enabling more boids to be simulated).

Compiling

You will need an installation of SFML compatible with SFML-2.3.2. If you run Debian or derivatives, you can install SFML by doing

sudo apt-get install libsfml-dev

After you've done that, you can compile by just doing

make

in the project directory. This will compile with gcc/g++. If you want a smaller executable (without debugging symbols), you can remove the -g option from the Makefile.

Running

To run the simulation, do

./sfml-boids <boid count>

where boid count is the initial number of boids. If omitted, it will default to 40.

Controls

• a: enable/disable rendering of velocity arrows/vectors of boids.
• s: enable/disable scatter mode. In scatter mode the boids will scatter instead of flock.
• Left click: place a new boid
• Right click: place a predator boid. Ordinary boids will flee from predators.
• Mouse wheel/scrolling: zoom in/out, effectively increasing the space the boids can move in.
