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.
Emitted every time the blend space's triangles are created, removed, or when one of their vertices changes position.
BLEND_MODE_INTERPOLATED = 0
The interpolation between animations is linear.
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.
BLEND_MODE_DISCRETE_CARRY = 2
Similar to BLEND_MODE_DISCRETE, but starts the new animation at the last animation's playback position.
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.
Controls the interpolation between animations. See BlendMode constants.
The blend space's X and Y axes' upper limit for the points' position. See add_blend_point.
The blend space's X and Y axes' lower limit for the points' position. See add_blend_point.
Position increment to snap to when moving a point.
If false
, the blended animations' frame are stopped when the blend value is 0
.
If true
, forcing the blended animations to advance frame.
Name of the blend space's X axis.
Name of the blend space's Y axis.
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.
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.
Returns the number of points in the blend space.
Returns the AnimationRootNode referenced by the point at index point
.
Returns the position of the point at index point
.
Returns the number of triangles in the blend space.
Returns the position of the point at index point
in the triangle of index triangle
.
Removes the point at index point
from the blend space.
Removes the triangle at index triangle
from the blend space.
Changes the AnimationNode referenced by the point at index point
.
Updates the position of the point at index point
on the blend axis.
