GUILayoutSpace

GUILayoutSpace is a component in the Unity game engine used to control the spacing between UI elements in a layout group. It is a part of the Unity UI system and is typically used with components like Vertical Layout Group and Horizontal Layout Group. When a GUILayoutSpace component is added to a GameObject that is a child of a layout group, it occupies a certain amount of space within that group, effectively pushing other elements away.

The primary purpose of GUILayoutSpace is to create visual separation or to reserve specific areas within a UI layout without needing to add a visible UI element. For instance, you might use it to add padding above or below a button or to create a gap between two images. This component is particularly useful for fine-tuning the appearance of UI elements when the automatic layout adjustments of components like Vertical Layout Group or Horizontal Layout Group are not sufficient.

You can adjust the width and height properties of GUILayoutSpace to control how much space it occupies. The layout group will then arrange its children, including the GUILayoutSpace, according to its own rules, taking the reserved space into account. This allows for a more flexible and precise control over UI layout composition, enabling developers to achieve desired visual arrangements more easily.
