Detailed Description

An animation channel that accepts a scalar each frame from some dynamic input provided by code.

This object operates in two modes: in explicit mode, the programmer should call set_value() each frame to indicate the new value; in implicit mode, the programmer should call set_value_node() to indicate the node whose X component will be copied to the scalar each frame.

◆ setValue()

setValue ( float  value)

Explicitly sets the value.

This will remove any node assigned via set_value_node().

◆ setValueNode()

setValueNode ( PandaNode  node)

Specifies a node whose transform will be queried each frame to implicitly specify the transform of this joint.

This will override the values set by set_value().

Member Data Documentation

◆ value

float value

Gets the value of the channel.

This will return the value explicitly specified by set_value() unless a value node was specified using set_value_node().Gets the value of the channel at the indicated frame.

◆ value_node

PandaNode value_node

Returns the node that was set via set_value_node(), if any.
