Legacy:DelayedTeleporter/UT Code

UT :: Actor (UT) >> NavigationPoint (UT) >> Teleporter >> DelayedTeleporter (Code)

To use this actor, subclass Teleporter with the following code. This class has been tested offline only. See Create A Subclass and Embedding Code for how to use this script. Set bStatic to False and bNoDelete to True in the DelayedTeleporter's default properties.

class DelayedTeleporter extends Teleporter;

Fyfe: Accept() can be reduced to:

simulated function bool Accept( Actor Incoming, Actor Source )
{

	{
