I'm a doctor, not a mechanic
From Unreal Wiki, The Unreal Engine Documentation Site
HudOverlays are used to display alternate information on the HUD.
Note that this is not a subclass of HUD. The functions defined in HUD are not readily available within this class.
- Render( Canvas C ) (simulated)
- EMPTY (allows access to the Canvas' functions)
- Destroyed() (simulated)
- If the Owner is a HUD, calls HUD(Owner).RemoveHudOverlay(self) before it calls Super.Destroyed().
