Blends linearly between two of any number of [AnimationNode] of any type placed on a virtual axis. A resource to add to an [AnimationNodeBlendTree]. This is a virtual axis on which you can add any type of [AnimationNode] using [method add_blend_point]. Outputs the linear blend of the two [AnimationNode]s closest to the node's current value. You can set the extents of the axis using the [member min_space] and [member max_space]. $DOCS_URL/tutorials/animation/animation_tree.html Adds a new point that represents a [param node] on the virtual axis at a given position set by [param pos]. You can insert it at a specific index using the [param at_index] argument. If you use the default value for [param at_index], the point is inserted at the end of the blend points array. Returns the number of points on the blend axis. Returns the [AnimationNode] referenced by the point at index [param point]. Returns the position of the point at index [param point]. Removes the point at index [param point] from the blend axis. Changes the [AnimationNode] referenced by the point at index [param point]. Updates the position of the point at index [param point] on the blend axis. Controls the interpolation between animations. See [enum BlendMode] constants. The blend space's axis's upper limit for the points' position. See [method add_blend_point]. The blend space's axis's lower limit for the points' position. See [method add_blend_point]. Position increment to snap to when moving a point on the axis. If [code]false[/code], the blended animations' frame are stopped when the blend value is [code]0[/code]. If [code]true[/code], forcing the blended animations to advance frame. Label of the virtual axis of the blend space. The interpolation between animations is linear. The blend space plays the animation of the node the blending position is closest to. Useful for frame-by-frame 2D animations. Similar to [constant BLEND_MODE_DISCRETE], but starts the new animation at the last animation's playback position.
