SurfaceGuiBase
Inherits from: LayerCollector → GuiBase2d → GuiBase → Instance → Object
SurfaceGuiBase is the LayerCollector base class for containers that render their GuiObject descendants onto a face of a BasePart in the 3D world. SurfaceGui and AdGui inherit from it.
The target part is set through the Adornee property; if no adornee is specified, the container renders on its parent when that parent is a BasePart. The Face property selects which surface of the part the UI is projected onto.

SurfaceGuiBase.Active
This property determines whether the SurfaceGui will sink input, for example if the parent or Adornee part contains a ClickDetector class like DragDetector.
Note that interactive UI elements like ImageButtons and TextButtons inside a SurfaceGui will only receive user input if they are parented to the PlayerGui (the SurfaceGui.Adorneee property can be used to target a part in the 3D world while the SurfaceGui itself remains in the PlayerGui). Additionally, the part's CanQuery property must be true for the interactive UI element to receive input.
