			<param index="0" name="id" type="int" />
			<description>
				Returns the item's name.
			</description>
		</method>
		<method name="get_item_navigation_layers" qualifiers="const">
			<return type="int" />
			<param index="0" name="id" type="int" />
			<description>
				Returns the item's navigation layers bitmask.
			</description>
		</method>
		<method name="get_item_navigation_mesh" qualifiers="const">

			</description>
		</method>
		<method name="get_item_preview" qualifiers="const">
			<return type="Texture2D" />
			<param index="0" name="id" type="int" />
			<description>
				When running in the editor, returns a generated item preview (a 3D rendering in isometric perspective). When used in a running project, returns the manually-defined item preview which can be set using [method set_item_preview]. Returns an empty [Texture2D] if no preview was manually set in a running project.
			</description>
		</method>
		<method name="get_item_shapes" qualifiers="const">
			<return type="Array" />
			<param index="0" name="id" type="int" />
			<description>
				Returns an item's collision shapes.

			</description>
		</method>
		<method name="get_last_unused_item_id" qualifiers="const">
			<return type="int" />
			<description>
				Gets an unused ID for a new item.
			</description>
