PyBulletClient

class compas_fab.backends.PyBulletClient(connection_type='gui', verbose=False)[source]

Bases: compas_fab.backends.pybullet.client.PyBulletBase, compas_fab.backends.interfaces.client.ClientInterface

Interface to use pybullet as backend.

compasfab.backends.PyBulletClient is a context manager type, so it’s best used in combination with the with statement to ensure resource deallocation.

Thanks to Yijiang Huang and his work in pybullet_planning for much inspiration.

Parameters

  • connection_type (str) – Sets the connection type. Defaults to 'gui'.

  • verbose (bool) – Use verbose logging. Defaults to False.

Examples

>>> from compas_fab.backends import PyBulletClient
>>> with PyBulletClient(connection_type='direct') as client:
...     print('Connected: %s' % client.is_connected)
Connected: True
