AnimationNode

Inherits: Resource < RefCounted < Object

Inherited By: AnimationNodeOutput, AnimationNodeSync, AnimationNodeTimeScale, AnimationNodeTimeSeek, AnimationRootNode

Base resource for AnimationTree nodes.

Description

Base resource for AnimationTree nodes. In general, it's not used directly, but you can create custom ones with custom blending formulas.

Inherit this when creating nodes mainly for use in AnimationNodeBlendTree, otherwise AnimationRootNode should be used instead.

Signals

  • removed_from_graph ( )

Emitted when the node was removed from the graph.


  • tree_changed ( )

Emitted by nodes that inherit from this class and that have an internal tree when one of their nodes changes. The nodes that emit this signal are AnimationNodeBlendSpace1D, AnimationNodeBlendSpace2D, AnimationNodeStateMachine, and AnimationNodeBlendTree.

Enumerations

enum FilterAction:

  • FILTER_IGNORE = 0 --- Do not use filtering.

  • FILTER_PASS = 1 --- Paths matching the filter will be allowed to pass.

  • FILTER_STOP = 2 --- Paths matching the filter will be discarded.

  • FILTER_BLEND = 3 --- Paths matching the filter will be blended (by the blend value).

Property Descriptions

  • bool filter_enabled

Setter

set_filter_enabled(value)

Getter

is_filter_enabled()

If true, filtering is enabled.

Method Descriptions

  • String _get_caption ( ) virtual const

When inheriting from AnimationRootNode, implement this virtual method to override the text caption for this node.


When inheriting from AnimationRootNode, implement this virtual method to return a child node by its name.


When inheriting from AnimationRootNode, implement this virtual method to return all children nodes in order as a name: node dictionary.


When inheriting from AnimationRootNode, implement this virtual method to return the default value of a parameter. Parameters are custom local memory used for your nodes, given a resource can be reused in multiple trees.


  • Array _get_parameter_list ( ) virtual const

When inheriting from AnimationRootNode, implement this virtual method to return a list of the properties on this node. Parameters are custom local memory used for your nodes, given a resource can be reused in multiple trees. Format is similar to Object.get_property_list.


  • bool _has_filter ( ) virtual const

When inheriting from AnimationRootNode, implement this virtual method to return whether the blend tree editor should display filter editing on this node.


When inheriting from AnimationRootNode, implement this virtual method to run some code when this node is processed. The time parameter is a relative delta, unless seek is true, in which case it is absolute.

Here, call the blend_input, blend_node or blend_animation functions. You can also use get_parameter and 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).


  • void add_input ( String name )

Adds an input to the node. This is only useful for nodes created for use in an AnimationNodeBlendTree.


Blend an animation by blend amount (name must be valid in the linked AnimationPlayer). A time and delta may be passed, as well as whether seeked happened.


Blend an input. This is only useful for nodes created for an AnimationNodeBlendTree. The time parameter is a relative delta, unless seek is true, in which case it is absolute. A filter mode may be optionally passed (see FilterAction for options).


Blend another animation node (in case this node contains children animation nodes). This function is only useful if you inherit from AnimationRootNode instead, else editors will not display your node for addition.


  • int get_input_count ( ) const

Amount of inputs in this node, only useful for nodes that go into AnimationNodeBlendTree.


Gets the name of an input by index.


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


Returns whether the given path is filtered.


  • void remove_input ( int index )

Removes an input, call this only when inactive.


Adds or removes a path for the filter.


Sets a custom parameter. These are used as local memory, because resources can be reused across the tree or scenes.
