<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.

Blend an input. This is only useful for nodes created for an [AnimationNodeBlendTree]. The [code]time[/code] parameter is a relative delta, unless [code]seek[/code] is [code]true[/code], in which case it is absolute. A filter mode may be optionally passed (see [enum FilterAction] for options).

|
|
Blend another animation 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>
|
|
User-defined callback called when a custom 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).
