Signals

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).

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.

Property Descriptions

  • bool filter_enabled
Setter set_filter_enabled(value)
Getter is_filter_enabled()

Return whether filtering is enabled.

Method Descriptions

  • void add_input ( String name )

Add 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 mas be passed, as well as whether seek happened.

Blend an input. This is only useful for nodes created for an AnimationBlendTree. Time is a delta, unless “seek” is true, in which case it is absolute. A filter mode may be optionally passed.

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.

  • String get_caption ( ) virtual

Get the text caption for this node (used by some editors)

Get the a child node by index (used by editors inheriting from AnimationRootNode).

Get all children nodes, in order as a name:node dictionary. Only useful when inheriting AnimationRootNode.

  • int get_input_count ( ) const

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

Get the name of an input by index.

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

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.

  • Array get_parameter_list ( ) virtual

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 Object.get_property_list

  • String has_filter ( ) virtual

Return true whether you want the blend tree editor to display filter editing on this node.

Return true wether a given path is filtered.

  • void process ( float time, bool seek ) virtual

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

  • void remove_input ( int index )

Remove an input, call this only when inactive.

Add/Remove a path for the filter.

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