Func areaportal

Entity Description

A portal brush is used to manage visibility in maps. Portals define areas, or spaces that are connected in the map. Both sides of a portal cannot touch the same area, for example, a doughnut-shaped map would require at least two portals to divide the map into two areas. A linear map could be divided into two areas with a single area portal. See Controlling Geometry Visibility and Compile Times: Areaportals for more information.

• Behavior with linked doors can be tricky. If the areaportal is doing the opposite of what it should, closing when the door is open and vice versa, change the areaportal's initial state.
• Areaportals do not take into account geometry between the portal volume and the player when considering visibility.
