  77. Description
  78. -----------
  79. Base resource for :ref:`AnimationTree<class_AnimationTree>` nodes. In general, it's not used directly, but you can create custom ones with custom blending formulas.
  80. Inherit this when creating nodes mainly for use in :ref:`AnimationNodeBlendTree<class_AnimationNodeBlendTree>`, otherwise :ref:`AnimationRootNode<class_AnimationRootNode>` should be used instead.

  87. +----------+---------------------------+
  88. | *Getter* | is_filter_enabled() |
  89. +----------+---------------------------+
  90. Returns whether filtering is enabled.

  98. Blend an animation by "blend" amount (name must be valid in the linked :ref:`AnimationPlayer<class_AnimationPlayer>`). A time and delta mas be passed, as well as whether seek happened.
  99. .. _class_AnimationNode_method_blend_input:

  101. Blend an input. This is only useful for nodes created for an :ref:`AnimationNodeBlendTree<class_AnimationNodeBlendTree>`. Time is a delta, unless "seek" is ``true``, in which case it is absolute. A filter mode may be optionally passed.
  102. .. _class_AnimationNode_method_blend_node:

  104. Blend another animaiton node (in case this node contains children animation nodes). This function is only useful if you inherit from :ref:`AnimationRootNode<class_AnimationRootNode>` instead, else editors will not display your node for addition.
  105. .. _class_AnimationNode_method_get_caption:
  106. - :ref:`String<class_String>` **get_caption** **(** **)** virtual
  107. Gets the text caption for this node (used by some editors).
  108. .. _class_AnimationNode_method_get_child_by_name:
  109. - :ref:`Object<class_Object>` **get_child_by_name** **(** :ref:`String<class_String>` name **)** virtual
  110. Gets a child node by index (used by editors inheriting from :ref:`AnimationRootNode<class_AnimationRootNode>`).
  111. .. _class_AnimationNode_method_get_child_nodes:
  112. - :ref:`Dictionary<class_Dictionary>` **get_child_nodes** **(** **)** virtual
  113. Gets all children nodes in order as a ``name: node`` dictionary. Only useful when inheriting :ref:`AnimationRootNode<class_AnimationRootNode>`.
  114. .. _class_AnimationNode_method_get_input_count:
  115. - :ref:`int<class_int>` **get_input_count** **(** **)** const
  116. Amount of inputs in this node, only useful for nodes that go into :ref:`AnimationNodeBlendTree<class_AnimationNodeBlendTree>`.
  117. .. _class_AnimationNode_method_get_input_name:
  118. - :ref:`String<class_String>` **get_input_name** **(** :ref:`int<class_int>` input **)**
  119. Gets the name of an input by index.

  121. - :ref:`Variant<class_Variant>` **get_parameter** **(** :ref:`String<class_String>` name **)** const
  122. Gets the value of a parameter. Parameters are custom local memory used for your nodes, given a resource can be reused in multiple trees.
  123. .. _class_AnimationNode_method_get_parameter_default_value:
  124. - :ref:`Variant<class_Variant>` **get_parameter_default_value** **(** :ref:`String<class_String>` name **)** virtual

  126. .. _class_AnimationNode_method_get_parameter_list:
  127. - :ref:`Array<class_Array>` **get_parameter_list** **(** **)** virtual
  128. 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 :ref:`Object.get_property_list<class_Object_method_get_property_list>`.
  129. .. _class_AnimationNode_method_has_filter:
  130. - :ref:`String<class_String>` **has_filter** **(** **)** virtual
  131. Returns ``true`` whether you want the blend tree editor to display filter editing on this node.
  132. .. _class_AnimationNode_method_is_path_filtered:
  133. - :ref:`bool<class_bool>` **is_path_filtered** **(** :ref:`NodePath<class_NodePath>` path **)** const
  134. Returns ``true`` whether a given path is filtered.
  135. .. _class_AnimationNode_method_process:
  136. - void **process** **(** :ref:`float<class_float>` time, :ref:`bool<class_bool>` seek **)** virtual
  137. Called when a custom node is processed. The argument "time" is relative, unless "seek" is ``true`` (in which case it is absolute).
  138. Here, call the :ref:`blend_input<class_AnimationNode_method_blend_input>`, :ref:`blend_node<class_AnimationNode_method_blend_node>` or :ref:`blend_animation<class_AnimationNode_method_blend_animation>` functions.
  139. You can also use :ref:`get_parameter<class_AnimationNode_method_get_parameter>` and :ref:`set_parameter<class_AnimationNode_method_set_parameter>` to modify local memory.
  140. This function returns the time left for the current animation to finish (if unsure, just pass the value from the main blend being called).
  141. .. _class_AnimationNode_method_remove_input:
  142. - void **remove_input** **(** :ref:`int<class_int>` index **)**
  143. Removes an input, call this only when inactive.

  145. - void **set_filter_path** **(** :ref:`NodePath<class_NodePath>` path, :ref:`bool<class_bool>` enable **)**

  147. .. _class_AnimationNode_method_set_parameter:
  148. - void **set_parameter** **(** :ref:`String<class_String>` name, :ref:`Variant<class_Variant>` value **)**
  149. Sets a custom parameter. These are used as local storage, because resources can be reused across the tree or scenes.
