		A 2D line.
	</brief_description>
	<description>
		A line through several points in 2D space.
		[b]Note:[/b] By default, Godot can only draw up to 4,096 polygon points at a time. To increase this limit, open the Project Settings and increase [member ProjectSettings.rendering/limits/buffers/canvas_polygon_buffer_size_kb] and [member ProjectSettings.rendering/limits/buffers/canvas_polygon_index_buffer_size_kb].

		<method name="add_point">
			<return type="void" />
			<argument index="0" name="position" type="Vector2" />
			<argument index="1" name="at_position" type="int" default="-1" />
			<description>
				Adds a point at the [code]position[/code]. Appends the point at the end of the line.
				If [code]at_position[/code] is given, the point is inserted before the point number [code]at_position[/code], moving that point (and every point after) after the inserted point. If [code]at_position[/code] is not given, or is an illegal value ([code]at_position &lt; 0[/code] or [code]at_position &gt;= [method get_point_count][/code]), the point will be appended at the end of the point list.
			</description>
		</method>
		<method name="clear_points">
			<return type="void" />
			<description>
				Removes all points from the line.
			</description>
		</method>
		<method name="get_point_count" qualifiers="const">
			<return type="int" />
			<description>
				Returns the Line2D's amount of points.
			</description>
		</method>
		<method name="get_point_position" qualifiers="const">
			<return type="Vector2" />
			<argument index="0" name="i" type="int" />
			<description>
				Returns point [code]i[/code]'s position.
			</description>
		</method>
		<method name="remove_point">
			<return type="void" />
			<argument index="0" name="i" type="int" />
			<description>
				Removes the point at index [code]i[/code] from the line.

			<return type="void" />
			<argument index="0" name="i" type="int" />
			<argument index="1" name="position" type="Vector2" />
			<description>
				Overwrites the position in point [code]i[/code] with the supplied [code]position[/code].

		<member name="antialiased" type="bool" setter="set_antialiased" getter="get_antialiased" default="false">
			If [code]true[/code], the line's border will be anti-aliased.

		</member>
		<member name="points" type="PoolVector2Array" setter="set_points" getter="get_points" default="PoolVector2Array(  )">
			The points that form the lines. The line is drawn between every point set in this array. Points are interpreted as local vectors.
		</member>
		<member name="round_precision" type="int" setter="set_round_precision" getter="get_round_precision" default="8">
			The smoothness of the rounded joints and caps. This is only used if a cap or joint is set as round.
