Gets the text caption for this node (used by some editors).

Gets all children nodes in order as a [code]name: node[/code] dictionary. Only useful when inheriting [AnimationRootNode].

Gets the default value of a parameter. Parameters are custom local memory used for your nodes, given a resource can be reused in multiple trees.

Gets the property information for parameter. Parameters are custom local memory used for your nodes, given a resource can be reused in multiple trees. Format is similar to [method Object.get_property_list].

User-defined callback called when a custom node is processed. The [param time] parameter is a relative delta, unless [param seek] is [code]true[/code], in which case it is absolute.
When inheriting from [AnimationRootNode], implement this virtual method to run some code when this node is processed. The [param time] parameter is a relative delta, unless [param seek] is [code]true[/code], in which case it is absolute.
Here, call the [method blend_input], [method blend_node] or [method blend_animation] functions. You can also use [method get_parameter] and [method set_parameter] to modify local memory.
This function should return the time left for the current animation to finish (if unsure, pass the value from the main blend being called).
