AnimationNode¶
Inherits: Resource < RefCounted < Object
Inherited By: AnimationNodeOutput, AnimationNodeSync, AnimationNodeTimeScale, AnimationNodeTimeSeek, AnimationRootNode
Base class for AnimationTree nodes. Not related to scene 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 animation nodes mainly for use in AnimationNodeBlendTree, otherwise AnimationRootNode should be used instead.

Signals¶
animation_node_removed ( int object_id, String name )
Emitted by nodes that inherit from this class and that have an internal tree when one of their animation nodes removes. The animation nodes that emit this signal are AnimationNodeBlendSpace1D, AnimationNodeBlendSpace2D, AnimationNodeStateMachine, and AnimationNodeBlendTree.
animation_node_renamed ( int object_id, String old_name, String new_name )
Emitted by nodes that inherit from this class and that have an internal tree when one of their animation node names changes. The animation nodes that emit this signal are AnimationNodeBlendSpace1D, AnimationNodeBlendSpace2D, AnimationNodeStateMachine, and AnimationNodeBlendTree.
tree_changed ( )
Emitted by nodes that inherit from this class and that have an internal tree when one of their animation nodes changes. The animation nodes that emit this signal are AnimationNodeBlendSpace1D, AnimationNodeBlendSpace2D, AnimationNodeStateMachine, AnimationNodeBlendTree and AnimationNodeTransition.
Enumerations¶
enum FilterAction:
FilterAction FILTER_IGNORE = 0
Do not use filtering.
FilterAction FILTER_PASS = 1
Paths matching the filter will be allowed to pass.
FilterAction FILTER_STOP = 2
Paths matching the filter will be discarded.
FilterAction FILTER_BLEND = 3
Paths matching the filter will be blended (by the blend value).
Property Descriptions¶
bool 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 animation node.
AnimationNode _get_child_by_name ( StringName name ) virtual const
When inheriting from AnimationRootNode, implement this virtual method to return a child animation node by its name.
Dictionary _get_child_nodes ( ) virtual const
When inheriting from AnimationRootNode, implement this virtual method to return all children animation nodes in order as a name: node dictionary.
Variant _get_parameter_default_value ( StringName parameter ) virtual const
When inheriting from AnimationRootNode, implement this virtual method to return the default value of a parameter. Parameters are custom local memory used for your animation 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 animation node. Parameters are custom local memory used for your animation 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 animation node.
bool _is_parameter_read_only ( StringName parameter ) virtual const
When inheriting from AnimationRootNode, implement this virtual method to return whether the parameter is read-only. Parameters are custom local memory used for your animation nodes, given a resource can be reused in multiple trees.
float _process ( float time, bool seek, bool is_external_seeking, bool test_only ) virtual const
When inheriting from AnimationRootNode, implement this virtual method to run some code when this animation 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).
bool add_input ( String name )
Adds an input to the animation node. This is only useful for animation nodes created for use in an AnimationNodeBlendTree. If the addition fails, returns false.
void blend_animation ( StringName animation, float time, float delta, bool seeked, bool is_external_seeking, float blend, LoopedFlag looped_flag=0 )
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.
A looped_flag is used by internal processing immediately after the loop. See also LoopedFlag.
