Overlays

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)
