AnimationNodeBlendSpace2D¶

Inherits: AnimationRootNode < AnimationNode < Resource < RefCounted < Object

A set of AnimationRootNodes placed on 2D coordinates, crossfading between the three adjacent ones. Used by AnimationTree.

Description¶

A resource used by AnimationNodeBlendTree.

AnimationNodeBlendSpace1D represents a virtual 2D space on which AnimationRootNodes are placed. Outputs the linear blend of the three adjacent animations using a Vector2 weight. Adjacent in this context means the three AnimationRootNodes making up the triangle that contains the current value.

You can add vertices to the blend space with add_blend_point and automatically triangulate it by setting auto_triangles to true. Otherwise, use add_triangle and remove_triangle to triangulate the blend space by hand.

Signals¶

triangles_updated ( )

Emitted every time the blend space's triangles are created, removed, or when one of their vertices changes position.

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¶

bool auto_triangles = true

void set_auto_triangles ( bool value )
bool get_auto_triangles ( )

If true, the blend space is triangulated automatically. The mesh updates every time you add or remove points with add_blend_point and remove_blend_point.

BlendMode blend_mode = 0

void set_blend_mode ( BlendMode value )
BlendMode get_blend_mode ( )

Controls the interpolation between animations. See BlendMode constants.

Vector2 max_space = Vector2(1, 1)

void set_max_space ( Vector2 value )
Vector2 get_max_space ( )

The blend space's X and Y axes' upper limit for the points' position. See add_blend_point.

Vector2 min_space = Vector2(-1, -1)

void set_min_space ( Vector2 value )
Vector2 get_min_space ( )

The blend space's X and Y axes' lower limit for the points' position. See add_blend_point.

Vector2 snap = Vector2(0.1, 0.1)

void set_snap ( Vector2 value )
Vector2 get_snap ( )

Position increment to snap to when moving a point.

bool sync = false

void set_use_sync ( bool value )
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 x_label = "x"

void set_x_label ( String value )
String get_x_label ( )

Name of the blend space's X axis.

String y_label = "y"

void set_y_label ( String value )
String get_y_label ( )

Name of the blend space's Y axis.

Method Descriptions¶

void add_blend_point ( AnimationRootNode node, Vector2 pos, int at_index=-1 )

Adds a new point that represents a node at the 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.

void add_triangle ( int x, int y, int z, int at_index=-1 )

Creates a new triangle using three points x, y, and z. Triangles can overlap. You can insert the triangle 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 in the blend space.

AnimationRootNode get_blend_point_node ( int point ) const

Returns the AnimationRootNode referenced by the point at index point.

Vector2 get_blend_point_position ( int point ) const

Returns the position of the point at index point.

int get_triangle_count ( ) const

Returns the number of triangles in the blend space.

int get_triangle_point ( int triangle, int point )

Returns the position of the point at index point in the triangle of index triangle.

void remove_blend_point ( int point )

Removes the point at index point from the blend space.

void remove_triangle ( int triangle )

Removes the triangle at index triangle from the blend space.

void set_blend_point_node ( int point, AnimationRootNode node )

Changes the AnimationNode referenced by the point at index point.

void set_blend_point_position ( int point, Vector2 pos )

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