 			The bounding box's width, height, and depth starting from [member position]. Setting this value also affects the [member end] point.
-			[b]Note:[/b] It's recommended setting the width, height, and depth to non-negative values. This is because most methods in Godot assume that the [member position] is the bottom-left-back corner, and the [member end] is the top-right-forward corner. To get an equivalent bounding box with non-negative size, use [method abs].
