		Base resource for [AnimationTree] nodes.
	</brief_description>
	<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.

		<method name="get_caption" qualifiers="virtual">
			<return type="String" />
			<description>
				When inheriting from [AnimationRootNode], implement this virtual method to override the text caption for this node.
			</description>
		</method>
		<method name="get_child_by_name" qualifiers="virtual">
			<return type="Object" />
			<argument index="0" name="name" type="String" />
			<description>
				When inheriting from [AnimationRootNode], implement this virtual method to return a child node by its [code]name[/code].
			</description>
		</method>
		<method name="get_child_nodes" qualifiers="virtual">
			<return type="Dictionary" />
			<description>
				When inheriting from [AnimationRootNode], implement this virtual method to return all children nodes in order as a [code]name: node[/code] dictionary.
			</description>
		</method>
		<method name="get_input_count" qualifiers="const">
			<return type="int" />
			<description>
				Amount of inputs in this node, only useful for nodes that go into [AnimationNodeBlendTree].
			</description>
		</method>
		<method name="get_input_name">
			<return type="String" />
			<argument index="0" name="input" type="int" />
			<description>
				Gets the name of an input by index.

			<return type="Variant" />
			<argument index="0" name="name" type="StringName" />
			<description>
			</description>
		</method>
		<method name="get_parameter_default_value" qualifiers="virtual">
			<return type="Variant" />
			<argument index="0" name="name" type="String" />
			<description>
				When inheriting from [AnimationRootNode], implement this virtual method to return the default value of parameter "[code]name[/code]". Parameters are custom local memory used for your nodes, given a resource can be reused in multiple trees.
			</description>
		</method>
		<method name="get_parameter_list" qualifiers="virtual">
			<return type="Array" />
			<description>
				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 [method Object.get_property_list].
			</description>
		</method>
		<method name="has_filter" qualifiers="virtual">
			<return type="bool" />
			<description>
				When inheriting from [AnimationRootNode], implement this virtual method to return whether the blend tree editor should display filter editing on this node.
			</description>
		</method>
		<method name="is_path_filtered" qualifiers="const">
			<return type="bool" />
			<argument index="0" name="path" type="NodePath" />
			<description>
				Returns whether the given path is filtered.

		</method>
		<method name="process" qualifiers="virtual">
			<return type="void" />
			<argument index="0" name="time" type="float" />
			<argument index="1" name="seek" type="bool" />
			<description>
				When inheriting from [AnimationRootNode], implement this virtual method to run some code when this node is processed. The [code]time[/code] parameter is a relative delta, unless [code]seek[/code] 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).

		</method>
		<method name="remove_input">
			<return type="void" />
			<argument index="0" name="index" type="int" />
			<description>

			<return type="void" />
			<argument index="0" name="path" type="NodePath" />
			<argument index="1" name="enable" type="bool" />
			<description>
				Adds or removes a path for the filter.
			</description>
