AgentMatrix object representing the moving
ncol = 2) with the first column
pxcor and the second
pycor representing the

Logical to determine if the

torus = FALSE.
AgentMatrix representing the
turtles with updated
The number of agents/locations in
agents2 must be equal to 1 or
to the length of
If `torus = FALSE`, `world` does not need to be provided. If `torus = TRUE` and the distance from one `turtles` to its corresponding agent/location `agents2` is smaller around the sides of the `world` than across it, then the direction to the agent/location `agents2` going around the sides of the `world` is given to the `turtle`. If a turtle is facing its own location, its heading does not change.
