	<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].

			<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.
