VRService
VRService is responsible for handling interactions between Roblox and Virtual Reality (VR). Its methods, properties, and events help you provide the best experience for end users seeking to experience Roblox on VR devices.
See VR Guidelines for more information on publishing an experience for VR devices.
Code Samples
local VRService = game:GetService("VRService")
local part = workspace.Part
local handOffset = VRService:GetUserCFrame(Enum.UserCFrame.LeftHand)
-- Account for headscale
handOffset = handOffset.Rotation + handOffset.Position * workspace.CurrentCamera.HeadScale
part.CFrame = workspace.CurrentCamera.CFrame * handOffset
Summary
Properties
Automatically adjusts scaling in VR to align the player with their avatar.
When true, a VR player will be able to animate their hands and head using their controllers and headset.
When true, a VR player's view will fade to black when their head collides with an object.
Describes what Enum.UserCFrame is responsible for input in VR.
Describes whether the user is using a virtual reality device.
Methods
Returns the VRTouchpadMode indicating the mode of a specified VRTouchpad.
Returns a CFrame describing the position & orientation of a specified virtual reality device as an offset from a point in real world space.
Returns true if the specified Enum.UserCFrame is available to be listened to.
Re-centers the CFrame to the current location of the VR headset being worn by the user.
Requests navigation to the specified CFrame using the specified Enum.UserCFrame as the origin for the visualizer parabola.
Sets the mode of the specified Enum.VRTouchpad to the specified Enum.VRTouchpadMode.
Events
Fired when navigation is requested from VRService.
Fires if the Enum.VRTouchpadMode of a Enum.VRTouchpad is changed.
Fires when a Enum.UserCFrame is changed.
Fires when a Enum.UserCFrame is enabled or disabled.
Properties
AutomaticScaling
When set to Enum.VRScaling.World, Camera.HeadScale adjusts so that the scale of the world is seen from the avatar's perspective. A player with a small avatar will perceive the objects around them as larger than a player with a large avatar will.
AvatarGestures
When set to true, a VR player will be able to animate their hands and head using their controllers and headset.
This property must be set on the server.
ControllerModels
FadeOutViewOnCollision
When true, a VR player's view fades to black when their head collides with an object. This property prevents players from being able to see through walls while in VR. The default value is true.
GuiInputUserCFrame
This property describes what Enum.UserCFrame is responsible for input in VR. For instance, if a VR headset is responsible, the value of this property will be Enum.UserCFrame.Head.
To check if Roblox detects any VR devices, which would be responsible for input in VR, you can check the VREnabled property.
Code Samples
local VRService = game:GetService("VRService")
if VRService.VREnabled then
print(VRService.GuiInputUserCFrame.Name)
else
print("No VR device detected!")
end
LaserPointer
ThirdPersonFollowCamEnabled
VREnabled
This property describes whether the user is using a virtual reality (VR) device.
If a VR device is enabled, you can interact with its location and movement through methods such as UserInputService:GetUserCFrame(). You can also react to VR device movement using the UserInputService.UserCFrameChanged event.
local UserInputService = game:GetService("UserInputService")local isUsingVR = UserInputService.VREnabledif isUsingVR thenprint("User is using a VR headset!")elseprint("User is not using a VR headset!")end
This property can only be used in a LocalScript.

Code Samples
local VRService = game:GetService("VRService")
local Players = game:GetService("Players")
local player = Players.LocalPlayer
local character = player.CharacterAdded:Wait()
local head = character:WaitForChild("Head")
local function TrackHead(inputType, value)
if inputType == Enum.UserCFrame.Head then
head.CFrame = value
end
end
if VRService.VREnabled then
-- Set the initial CFrame
head.CFrame = VRService:GetUserCFrame(Enum.UserCFrame.Head)
-- Track VR headset movement and mirror for character's head
VRService.UserCFrameChanged:Connect(TrackHead)
end
Methods
GetTouchpadMode
This method returns the Enum.VRTouchpadMode indicating the mode of a specified Enum.VRTouchpad. The returned mode indicates how the user interacts with their touchpad to play the game.
This can also be used alongside the several UserInputService VR methods and events.
This method will only work when used in a LocalScript.
Parameters
The specified VRTouchpad.
Returns
The mode of the specified VRTouchpad.
Code Samples
local VRService = game:GetService("VRService")
VRService:GetTouchpadMode(Enum.VRTouchpad.Left)
GetUserCFrame
This method returns a CFrame describing the position and orientation of a specified virtual reality (VR) device as an offset from a point in real world space. This method should be used when implementing VR compatibility into a game to obtain and track the movement of a connected VR device.
By using the method, developers can implement features such as re-positioning the user's in-game character corresponding to the location of a connected VR device. This can be done by changing the CFrame of the user's in-game character to match the CFrame of the specified VR device using the UserCFrame enum and CFrame value arguments passed by the event.
VRService also provides a UserCFrameChanged event that automatically fires when the CFrame of connected VR device changes, so long it is used in a LocalScript.
This method will only work when used in a LocalScript.
Parameters
The specified UserCFrame.
Returns
Code Samples
local Workspace = game:GetService("Workspace")
local VRService = game:GetService("VRService")
local camera = Workspace.CurrentCamera
local part = script.Parent.Part
local handOffset = VRService:GetUserCFrame(Enum.UserCFrame.LeftHand)
-- Account for headscale
handOffset = handOffset.Rotation + handOffset.Position * camera.HeadScale
part.CFrame = camera.CFrame * handOffset
GetUserCFrameEnabled
This method returns true if the specified Enum.UserCFrame virtual reality device (VR) is available to be listened to. It can be used to determine whether a specified VR device, such as Enum.UserCFrame.Head, is connected to the user's game.
This can also be used alongside the several UserInputService VR methods and events.
This method will only work when used in a LocalScript.
Parameters
The specified type of VR device.
Returns
A boolean indicating whether the specified VR device is enabled (true) or disabled (false).
Code Samples
local VRService = game:GetService("VRService")
local isEnabled = VRService:GetUserCFrameEnabled(Enum.UserCFrame.Head)
if isEnabled then
print("VR device is enabled!")
else
print("VR device is disabled!")
end
RecenterUserHeadCFrame
This method re-centers the CFrame of the user's head to the current location of the VR headset being worn by the user. It can be used to ensure that the user's in-game head is positioned according to the location of the user's VR headset.
This behaves identically to UserInputService:RecenterUserHeadCFrame().
This method will only work when used in a LocalScript.
Returns
Code Samples
local VRService = game:GetService("VRService")
VRService:RecenterUserHeadCFrame()
RequestNavigation
This method requests navigation to the specified CFrame using the specified Enum.UserCFrame as the origin for the visualizer parabola. It can be used to incorporate virtual reality (VR) into your game by providing a means to visualize a navigation path from the user's VR device to a destination.
VRService has a similar event, NavigationRequested, used to detect such requests. This can also be used alongside the several UserInputService VR methods and events.
This method will only work when used in a LocalScript.
Parameters
The VR device for which the navigation is requested.
Returns
Code Samples
local VRService = game:GetService("VRService")
local destination = workspace:FindFirstChild("NavigationDestination")
VRService:RequestNavigation(Enum.UserCFrame.Head, destination.CFrame)
SetTouchpadMode
This method sets the mode of the specified Enum.VRTouchpad to the specified Enum.VRTouchpadMode. It can be used to change the user's virtual reality (VR) touchpad mode so that the user interacts with the game differently using the touchpad.
This can also be used alongside the several UserInputService VR methods and events.
This method will only work when used in a LocalScript.
Parameters
The specified VRTouchpad you want to set the mode of.
The mode you want to set the specified VRTouchpad to.
Returns
Code Samples
local VRService = game:GetService("VRService")
VRService:SetTouchpadMode(Enum.VRTouchpad.Left, Enum.VRTouchpadMode.Touch)
Events
NavigationRequested
This event fires when navigation is requested from VRService for a specified Enum.UserCFrame VR device. It fires with a CFrame coordinate and the specified Enum.UserCFrame indicating the device requesting the navigation.
This event can be used alongside UserInputService service events and methods.
Since this event fires locally, it can only be used in a LocalScript.
Parameters
Indicates the VR device for which navigation is requested.
Code Samples
local VRService = game:GetService("VRService")
VRService.TouchpadModeChanged:Connect(function(cframe, inputUserCFrame)
print(inputUserCFrame.Name .. " made request with CFrame: " .. cframe)
end)
TouchpadModeChanged
This event fires if the Enum.VRTouchpadMode of a Enum.VRTouchpad is changed. You can use this event to track the states of VR touchpads connected via the user's client.
This event can be used alongside UserInputService service events and methods.
Since this event fires locally, it can only be used in a LocalScript.
Parameters
The touchpad that changed mode.
The new mode.
Code Samples
local VRService = game:GetService("VRService")
VRService.NavigationRequested:Connect(function(pad, mode)
print(pad.Name .. " Touchpad changed to state: " .. mode.Name)
end)
UserCFrameChanged
This event fires when a Enum.UserCFrame is changed, for instance when the user moves a connected VR device. It can be used alongside GetUserCFrame() to track the CFrame coordinates of a VR device, and when it changes/moves. It can also be used alongside UserInputService service events and methods.
Since this event fires locally, it can only be used in a LocalScript.
Parameters
The type of VR device that changed.
Code Samples
local VRService = game:GetService("VRService")
VRService.UserCFrameChanged:Connect(function(userCFrameType, cframeValue)
print(userCFrameType.Name .. " changed. Updated Frame: " .. tostring(cframeValue))
end)
UserCFrameEnabled
This event fires when a Enum.UserCFrame is enabled or disabled. It can be used alongside GetUserCFrameEnabled() to track whether a specified UserCFrame is enabled, and when its state changes. It can also be used alongside UserInputService service events and methods.
Since this event fires locally, it can only be used in a LocalScript.
Parameters
The UserCFrame getting enabled or disabled.
A boolean indicating whether the UserCFrame is enabled (true) or disabled (false).
Code Samples
local VRService = game:GetService("VRService")
VRService.UserCFrameEnabled:Connect(function(type, enabled)
if enabled then
print(type.Name .. " got enabled!")
else
print(type.Name .. " got disabled!")
end
end)
