Nathan Lovato a9d7f2ed9b Add documentation for AnimationNode* resources
I haven't put [code] bbcode around the amount of the AnimationNodeAdd* classes
because it's not exposed to GDScript.
Same for the +add, -add, etc. labels: they're just labels you can find in the
AnimationTree bottom panel.

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.

<description>
Blend another animaiton 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.

</description>
</method>
<method name="get_child_nodes" qualifiers="virtual">
<return type="Dictionary">
</return>

</method>
<method name="get_input_count" qualifiers="const">
<return type="int">
</return>
<description>
Amount of inputs in this node, only useful for nodes that go into [AnimationNodeBlendTree].

<return type="Variant">
</return>
<argument index="0" name="name" type="String">
</argument>
<description>
Get the value of a parameter. Parameters are custom local memory used for your nodes, given a resource can be reused in multiple trees.

<method name="get_parameter_default_value" qualifiers="virtual">
<return type="Variant">
</return>
<argument index="0" name="name" type="String">

<description>
Get the default value of a parameter. 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">
</return>
<description>
Get 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].
</description>
</method>
<method name="has_filter" qualifiers="virtual">
<return type="String">
</return>
<description>
Returns [code]true[/code] whether you want the blend tree editor to display filter editing on this node.

<description>
Called when a custom node is processed. The argument "time" is relative, unless "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 returns the time left for the current animation to finish (if unsure, just pass the value from the main blend being called).
