ColorChaser generates a series of SFColor values that progressively change from initial value to destination value.

X3D node tooltip: (X3D version 3.3 or later) [X3DChaserNode] ColorChaser generates a series of SFColor values that progressively change from initial value to destination value.

• Hint: ROUTE value_changed output events to one of a <Material> node's color fields, for example.
• Hint: X3D Scene Authoring Hints, Color https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#Color

Note that SFColor provides a variety of color constants.

Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.

Assign typed object value to SFString DEF field, similar to setDEF(String).

Parameters:

newValue - is new value for the DEF field.

Returns:

ColorChaser - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

getUSE

public String getUSE()

Provide String value from inputOutput SFString field named USE.

Tooltip: USE means reuse an already DEF-ed node ID, excluding all child nodes and all other attributes (except for containerField, which can have a different value).

• Hint: USE references to previously defined DEF geometry (instead of duplicating nodes) can improve performance.
• Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except for containerField) when defining a USE attribute.
• Warning: each USE value must match a corresponding DEF value that is defined earlier in the scene.

Overrides:

getUSE in class X3DConcreteNode

Returns:

value of USE field

See Also:

setUSE

public final ColorChaser setUSE(String newValue)

Accessor method to assign String value to inputOutput SFString field named USE.

Tooltip: USE means reuse an already DEF-ed node ID, excluding all child nodes and all other attributes (except for containerField, which can have a different value).

• Hint: USE references to previously defined DEF geometry (instead of duplicating nodes) can improve performance.
• Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except for containerField) when defining a USE attribute.
• Warning: each USE value must match a corresponding DEF value that is defined earlier in the scene.

Note: each USE node is still an independent object, with the USE value matching the DEF value in the preceding object.

Warning: invoking the setUSE() method on this node resets all other fields to their default values (except for containerField) and also releases all child nodes.

Warning: no other operations can be performed to modify a USE node other than setting an alternate containerField value.

Specified by:

setUSE in class X3DConcreteNode

Parameters:

newValue - is new value for the USE field.

Returns:

ColorChaser - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
