AnimationNodeBlendSpace1D

Inherits: AnimationRootNode < AnimationNode < Resource < RefCounted < Object

A set of AnimationRootNodes placed on a virtual axis, crossfading between the two adjacent ones. Used by AnimationTree.

Description

A resource used by AnimationNodeBlendTree.

AnimationNodeBlendSpace1D represents a virtual axis on which any type of AnimationRootNodes can be added using add_blend_point. Outputs the linear blend of the two AnimationRootNodes adjacent to the current value.

You can set the extents of the axis with min_space and max_space.

Enumerations

enum BlendMode: 🔗

BlendMode BLEND_MODE_INTERPOLATED = 0

The interpolation between animations is linear.

BlendMode BLEND_MODE_DISCRETE = 1

The blend space plays the animation of the animation node which blending position is closest to. Useful for frame-by-frame 2D animations.

BlendMode BLEND_MODE_DISCRETE_CARRY = 2

Similar to BLEND_MODE_DISCRETE, but starts the new animation at the last animation's playback position.


Property Descriptions

BlendMode blend_mode = 0 🔗

Controls the interpolation between animations. See BlendMode constants.


float max_space = 1.0 🔗

  • void set_max_space(value: float)

  • float get_max_space()

The blend space's axis's upper limit for the points' position. See add_blend_point.


float min_space = -1.0 🔗

  • void set_min_space(value: float)

  • float get_min_space()

The blend space's axis's lower limit for the points' position. See add_blend_point.


float snap = 0.1 🔗

Position increment to snap to when moving a point on the axis.


bool sync = false 🔗

  • void set_use_sync(value: bool)

  • bool is_using_sync()

If false, the blended animations' frame are stopped when the blend value is 0.

If true, forcing the blended animations to advance frame.


String value_label = "value" 🔗

  • void set_value_label(value: String)

  • String get_value_label()

Label of the virtual axis of the blend space.


Method Descriptions

void add_blend_point(node: AnimationRootNode, pos: float, at_index: int = -1) 🔗

Adds a new point that represents a node on the virtual axis at a given position set by pos. You can insert it at a specific index using the at_index argument. If you use the default value for at_index, the point is inserted at the end of the blend points array.


int get_blend_point_count() const 🔗

Returns the number of points on the blend axis.


AnimationRootNode get_blend_point_node(point: int) const 🔗

Returns the AnimationNode referenced by the point at index point.


float get_blend_point_position(point: int) const 🔗

Returns the position of the point at index point.


void remove_blend_point(point: int) 🔗

Removes the point at index point from the blend axis.


void set_blend_point_node(point: int, node: AnimationRootNode) 🔗

Changes the AnimationNode referenced by the point at index point.


void set_blend_point_position(point: int, pos: float) 🔗

Updates the position of the point at index point on the blend axis.
