AnimationNodeBlendSpace2D

Inherits: AnimationRootNode < AnimationNode < Resource < RefCounted < Object

Blends linearly between three AnimationNode of any type placed in a 2D space.

Description

A resource to add to an AnimationNodeBlendTree.

This node allows you to blend linearly between three animations using a Vector2 weight.

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 create up 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 node the 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

Controls the interpolation between animations. See BlendMode constants.


Vector2 max_space = Vector2(1, 1)

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


Vector2 min_space = Vector2(-1, -1)

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)

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"

Name of the blend space's X axis.


String y_label = "y"

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.
