Plotting building data causes AgentsOSMVisualization to throw BoundsError #1102
Description
Describe the bug
I need to plot buildings as well as road networks for my project so I checked out OSMMakie and followed the example provided in the README. I integrated it into Zombie Outbreak example to test it and it threw a BoundError trying to access 3rd element of a 2 element Vector.
Minimal Working Example
I changed the Zombie example to include building data
# # Zombie Outbreak in a City
using Agents
using Random
@agent struct Zombie(OSMAgent)
infected::Bool
speed::Float64
end
function initialise_zombies(; seed = 1234)
map_path = OSM.test_map()
properties = Dict(:dt => 1 / 60)
model = StandardABM(
Zombie,
OpenStreetMapSpace(map_path);
agent_step! = zombie_step!,
properties = properties,
rng = Random.MersenneTwister(seed)
)
for id in 1:100
start = random_position(model) # At an intersection
speed = rand(abmrng(model)) * 5.0 + 2.0 # Random speed from 2-7kmph
human = add_agent!(start, Zombie, model, false, speed)
OSM.plan_random_route!(human, model; limit = 50) # try 50 times to find a random route
end
## We'll add patient zero at a specific (longitude, latitude)
start = OSM.nearest_road((9.9351811, 51.5328328), model)
finish = OSM.nearest_node((9.945125635913511, 51.530876112711745), model)
speed = rand(abmrng(model)) * 5.0 + 2.0 # Random speed from 2-7kmph
zombie = add_agent!(start, model, true, speed)
plan_route!(zombie, finish, model)
## This function call creates & adds an agent, see `add_agent!`
return model
end
function zombie_step!(agent, model)
## Each agent will progress along their route
## Keep track of distance left to move this step, in case the agent reaches its
## destination early
distance_left = move_along_route!(agent, model, agent.speed * model.dt)
if is_stationary(agent, model) && rand(abmrng(model)) < 0.1
## When stationary, give the agent a 10% chance of going somewhere else
OSM.plan_random_route!(agent, model; limit = 50)
## Start on new route, moving the remaining distance
move_along_route!(agent, model, distance_left)
end
if agent.infected
## Agents will be infected if they get too close (within 10m) to a zombie.
map(i -> model[i].infected = true, nearby_ids(agent, model, 0.01))
end
return
end
# ## Visualising the fall of humanity
# Notice that to visualize Open Street Maps, the package OSMMakie.jl must be loaded
# as well, besides any Makie plotting backend such as CairoMakie.jl.
using CairoMakie, OSMMakie

zombie_size(agent) = agent.infected ? 10 : 8

My Workaround
osm_plot.plots[1].plots[3].inspectable[] = falseReplacing 3 with 2 or commenting it out makes the code compile and display the buildings. I am not sure how inspectables work so that's my current solution to see some buildings.
