	<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" />
			<param index="3" name="name" type="StringName" default="&amp;&quot;&quot;" />
			<description>
				Adds a new point with [param name] 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.
				[b]Note:[/b] If no name is provided, safe index is used as reference. In the future, empty names will be deprecated, so explicitly passing a name is recommended.

			The interpolation between animations is linear.

			The blend space plays the animation of the animation node which blending position is closest to. Useful for frame-by-frame 2D animations.

			All animations are time-scaled so they stay in sync, with the cycle length dynamically computed from active blend weights. This is self-normalizing: a solo animation plays at normal speed.
