Hello, I’m new to agents.jl and am planning on creating an agent based model for an evacuation simulation that integrates the impacts of psychological factors on agent velocity. Does the agents.jl package utilize the social force equation and if so, is there a way I can access it to modify it with my psychological force?

If you know the equation then it is straightforward to implement it as the `update_vel` function in Conrinuous Space . Have you had a look at the docs of continuous space ?
