Instance	Type	Description
i	Marker	The marker attached to the first body.
j	Marker	The marker attached to the second body.

Notes

1. The parent parameter can only be initialized by the constructor and should not be modified directly.

2. Only parent can be used as a positional argument in the constructor.

3. Instance is a reference to an entity. You cannot modify an instance, but can modify its properties.

Methods

Returns:

List of all graphic associated with this body.

Return type:

(list)
