The ifSGNodeField interface allows you to query, and get, set, and perform other similar manipulation operations on Scene Graph node fields. The ifSGNodeField interface also allows you to set and unset event observers on a subject node field.

Supported Methods

Description of Methods 

hasField(name as String) as Boolean

Returns true if the subject node has a field whose name exactly matches name, or whose fully lowercase analog is identical to that of name. Returns false otherwise.

getField(name as String) as Object

Returns the appropriately-typed value from the subject node field identified by name.

You can also use the node.field syntax to get the same result as getField(). That is, rectpos = rect.getField("translation") is equivalent to rectpos = rect.translation.

setField(name as String, value as Object)

Sets the value of the subject node field identified by name to value. This will fail and stop script execution if the value is not of the appropriate type.

You can also use the node.field syntax to get the same result as setField(). That is, rect.setField("opacity", 0.5) is equivalent to rect.opacity = 0.5.

setFields(aa as Object)

Sets the value of subject node fields indicated by the corresponding key. TBD actually not sure what this does, looks like a mass setting of fields using an associative array TBD

observeField(name as String,  function as String)

Triggers the callback function identified by function when the subject node field identified by name changes value.

unobserveField(name as String)

Removes the previously established connections between the subject node field identified by name and any callback functions.
