func_portal_orientation

func_portal_orientation is a brush entity available in Portal (series). It adjusts a portal's rotation to match a specified angle. The "front" of the portal points in the specified direction.

Bug: Broken in Portal 2. It will rotate existing portals to the specified direction when first enabled, but will not affect newly-placed ones.  [todo tested in?]

Workaround:Since it still works when first enabled, a logic_playerproxy can be used to fire an Enable input to the entity every time a portal is placed, which will orient the portals correctly. This can result in some odd behavior when placing portals near the edge of surfaces within the volume, func_portal_bumpers should be used to prevent this.

Keyvalues

Name (targetname) <string>

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

Angles to face (AnglesToFace) <angle>

The angles to rotate portals to.

Tip:An easy way to figure out what to set this to is to place a prop_portal, rotate it to the desired orientation, then look at its angles.

Match linked angles. (MatchLinkedAngles) <boolean>

If set, portals placed in this volume will have their angles match their linked portals. This only works for floor or ceiling portals with a currently linked partner that is on a surface with the same orientation.

Todo: Seems to be broken in P1? It does work in P2 if the workaround is used.

Start Disabled (StartDisabled) <boolean>

Stay dormant until activated (with theEnableinput).

Inputs

EnableDisable:

Enable / Disable

Enable/disable this entity from performing its task. It might also disappear from view.
