Connecting Nodes

Simple syntax

The syntax is an extension of an idea introduced in pymel and allows to write intuitive, easy to read statements.

Connect

Connections can be made using >> operator

control.spin >> joint.rx

Additionally channels can be connected to multiple outputs at once using << operator. Imagine a node with multiple output connections going outwards that is reflected in the operator shape.

control.twist << [joint1.rx, joint2.rx, joint3.rx]

Disconnect

Connected channels can be disconnected using != operator

control.spin != joint.rx

or using <> operator in Python 2

control.spin <> joint.rx

Alternatively all connections can be broken using the .disconnect() method

control.twist.disconnect()

List connections

Get an input

joint.rx.input()

Get outputs

control.twist.outputs()

Connections method

This is using the nc.listConnections function that operates on the called channel, thus using the same kwargs.

control.twist.connections()

Using nod.cmds

nc.listConnections(control.twist)

Check connection status

There are two ways of checking if two channels are connected.

control.rx >> joint.rx

control.rx.isConnectedTo(joint.rx)
# True

joint.rx.isConnectedTo(control.rx)
# False

control.rx >> joint.rx

control.rx in joint.rx
# True

joint.rx in control.rx
# False
