Info.png
This entity is not in the FGD by default .
See below for instructions on making it available.

trigger_portal is an brush entity in the Source base code. It moves touched entity to a target location, changing the model's orientation to match the exit target. It differs from trigger_teleport in that it "reorients physics" and (probably) preserves velocity. It seems to be an early test of the functionality of portals, which was replaced by prop_portal.

Note.pngNote:This entity is unavailable in any Valve game, though it has been re-enabled in Portal 2: Community Edition Portal 2: Community Edition . Other mods using custom binaries can enable the entity by editing server_base.vpc to include trigger_portal.cpp before building the project, or by adding the file within Visual Studio after building the project.
Icon-Bug.pngBug:The code for this entity will not compile on its own. See below for how to fix it.

FGD Code

@SolidClass base(Trigger, Angles) = trigger_portal :
	"A trigger volume which teleports touched entities and reorients their physics."
[
	RemotePortal(target_destination) : "Remote Portal" : : "The trigger_portal linked to this entity. Entities that touch this entity will be teleported to the Remote Portal."

	//Inputs
	input SetRemotePortal(string) : "Set the remote portal to the specified trigger_portal."
]

Code Fixes

Replace line 278 and 302 in trigger_portal.cpp with:

SetContextThink( &CTriggerPortal::DisabledThink, gpGlobals->curtime + 0.1, TRIGGER_DISABLED_THINK );

Remove lines 33 and 77-79, which should be:

DECLARE_SERVERCLASS();
IMPLEMENT_SERVERCLASS_ST( CTriggerPortal, DT_TriggerPortal )
 	SendPropEHandle(SENDINFO(m_hRemotePortal)),
END_SEND_TABLE()

There is no client class to send this entity handle to, nor is one needed.
