Overlays

Not to be confused with the Hammer Overlay Tool

You can make screen overlay effects just like when Gordon is being teleported out of Kleiner's lab early in the game. To do this use the env_screenoverlay entity and start it with a trigger output (via the StartOverlays input)

You can input your desired number of overlay names (see list below) and decide how long they each should last by setting Overlay Duration (-1 means it stays on until killed by eventual trigger)
