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.

• void set_auto_triangles ( bool value )

• bool get_auto_triangles ( )
