BasePlayerGui

Takes a screen position and returns a list of all the GuiObject instances that are occupying that screen position, sorted in the order they appear on-screen from top to bottom as the first and last index, respectively.

The main use case is to get GUI objects under the player's mouse or touch inputs to do things like allow selection or highlighting. These effects can already be achieved using GuiObject.MouseEnter and GuiObject.MouseLeave but this requires the developer to track these events for their UI objects all the time even if they only need this functionality in specific circumstances.

Since the child classes of BasePlayerGui inherit this function, it can be fired by class objects such as the PlayerGui and StarterGui folders.
