<brief_description>
A set of [AnimationRootNode]s placed on a virtual axis, crossfading between the two adjacent ones. Used by [AnimationTree].
</brief_description>
<description>
A resource used by [AnimationNodeBlendTree].
[AnimationNodeBlendSpace1D] represents a virtual axis on which any type of [AnimationRootNode]s can be added using [method add_blend_point]. Outputs the linear blend of the two [AnimationRootNode]s adjacent to the current value.
You can set the extents of the axis with [member min_space] and [member max_space].

<methods>
<method name="add_blend_point">
<return type="void" />
<param index="0" name="node" type="AnimationRootNode" />
<param index="1" name="pos" type="float" />
<param index="2" name="at_index" type="int" default="-1" />
<description>
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.

<member name="blend_mode" type="int" setter="set_blend_mode" getter="get_blend_mode" enum="AnimationNodeBlendSpace1D.BlendMode" default="0">
Controls the interpolation between animations. See [enum BlendMode] constants.
</member>
<member name="max_space" type="float" setter="set_max_space" getter="get_max_space" default="1.0">
The blend space's axis's upper limit for the points' position. See [method add_blend_point].
</member>
<member name="min_space" type="float" setter="set_min_space" getter="get_min_space" default="-1.0">
The blend space's axis's lower limit for the points' position. See [method add_blend_point].

The interpolation between animations is linear.

<constant name="BLEND_MODE_DISCRETE" value="1" enum="BlendMode">
The blend space plays the animation of the animation node which blending position is closest to. Useful for frame-by-frame 2D animations.
</constant>
<constant name="BLEND_MODE_DISCRETE_CARRY" value="2" enum="BlendMode">
Similar to [constant BLEND_MODE_DISCRETE], but starts the new animation at the last animation's playback position.
