VRTK_BasicTeleport

Overview

The basic teleporter updates the [CameraRig] x/z position in the game world to the position of a World Pointer's tip location which is set via the WorldPointerDestinationSet event. The y position is never altered so the basic teleporter cannot be used to move up and down game objects as it only allows for travel across a flat plane.

The Basic Teleport script is attached to the [CameraRig] prefab and requires an implementation of the WorldPointer script to be attached to another game object (e.g. VRTK_SimplePointer attached to the Controller object).

Inspector Parameters

• Blink Transition Speed: The fade blink speed can be changed on the basic teleport script to provide a customised teleport experience. Setting the speed to 0 will mean no fade blink effect is present. The fade is achieved via the SteamVR_Fade.cs script in the SteamVR Unity Plugin scripts.
• Distance Blink Delay: A range between 0 and 32 that determines how long the blink transition will stay blacked out depending on the distance being teleported. A value of 0 will not delay the teleport blink effect over any distance, a value of 32 will delay the teleport blink fade in even when the distance teleported is very close to the original position. This can be used to simulate time taking longer to pass the further a user teleports. A value of 16 provides a decent basis to simulate this to the user.
• Headset Position Compensation: If this is checked then the teleported location will be the position of the headset within the play area. If it is unchecked then the teleported location will always be the centre of the play area even if the headset position is not in the centre of the play area.
• Ignore Target With Tag Or Class: A string that specifies an object Tag or the name of a Script attached to an obejct and notifies the teleporter that the destination is to be ignored so the user cannot teleport to that location. It also ensure the pointer colour is set to the miss colour.
• Nav Mesh Limit Distance: The max distance the nav mesh edge can be from the teleport destination to be considered valid. If a value of 0 is given then the nav mesh restriction will be ignored.

Class Events

• Teleporting - Emitted when the teleport process has begun.
• Teleported - Emitted when the teleport process has successfully completed.

Event Payload

The event payload is reused from the VRTK_DestinationMarker Event Payload

Class Methods

InitDestinationSetListener/1

public void InitDestinationSetListener(GameObject markerMaker)

• Parameters
• GameObject markerMaker - The game object that is used to generate destination marker events, such as a controller.
• Returns
• none

The InitDestinationSetListener method is used to register the teleport script to listen to events from the given game object that is used to generate destination markers. Any destination set event emitted by a registered game object will initiate the teleport to the given destination location.

Example

SteamVR_Unity_Toolkit/Examples/004_CameraRig_BasicTeleport uses the VRTK_SimplePointer script on the Controllers to initiate a laser pointer by pressing the Touchpad on the controller and when the laser pointer is deactivated (release the Touchpad) then the user is teleported to the location of the laser pointer tip as this is where the pointer destination marker position is set to.
