Patches2D( tuple(int, int) dim, list[function(Patch)] props = [], list[function(Agent)] funcs = [] )

A list-like class (list of lists) that provides for retrieving patches by [x,y] index. This is not a full coordinate system, and should be subclassed by a full coordinate system.

WARNING: This is an internal class. Its use in user code is not recommended or supported, and its signature can change in future updates without warning. Use one of the suggested functions above instead, if applicable.

Initialization Parameters

• dim — tuple(int, int), required

  The dimensions of the grid.

• props — list[function(Patch)], optional

  A list of functions to be assigned to patches as properties by subclasses. For example PatchesRect defines Patch.up, Patch.down, Patch.left, and Patch.right, whereas PatchesPolar defines Patch.inward, Patch.outward, Patch.clockwise, and Patch.counterclockwise.

  Default value: []

• funcs — list[function(Agent)], optional

  A list of functions to be assigned to non-patch agents by subclasses. For example, subclasses should define Agent.orientTo() and Agent.distanceFrom() based on the coordinate system.

  Default value: []

Static Properties

• geometry — str

  The name of the patch geometry, to be set by subclasses.

  Initial value: ''
