Build a boids simulation world
Usage
boids_world(
dimension = c("2d", "3d"),
bounds = NULL,
boundary = c("wrap", "reflect", "open"),
obstacles = NULL,
attractors = NULL,
predators = NULL,
species = NULL
)
Arguments
- dimension
World dimension, either "2d" or "3d".
- bounds
Numeric matrix with rows x, y, and optionally z, and
columns min and max.
- boundary
Boundary behavior: wrap, reflect, or open.
- obstacles, attractors, predators
Data frames with coordinate columns.
- species
Optional species definition table.
Value
A boids_world list.
Examples
bounds <- matrix(
c(-2, -1, 2, 1),
ncol = 2,
dimnames = list(c("x", "y"), c("min", "max"))
)
world <- boids_world(
"2d",
bounds = bounds,
boundary = "reflect",
obstacles = data.frame(x = 0, y = 0, radius = 0.25),
attractors = data.frame(x = 1.5, y = 0.4, strength = 0.5)
)
world$boundary
#> [1] "reflect"
world$obstacles
#> x y radius z
