# VR Input
Input from VR is available both clientside and serverside in Simulate() all through Input.VR.
## Hands
<upload src="a5727/8dabdcb06b430d5.mp4" size="6096770" name="vrhands.mp4" />
Both hands are represented as Input.VR.LeftHand and Input.VR.RightHand, this struct contains the position and rotation of each hand.
```csharp
// Replicate the transform of the left hand onto the entity
Entity.Transform = Input.VR.LeftHand.Transform;
```
You can access the inputs for each hand's controller. This is generic to to support as much of the mainstream controllers as possible.
```csharp
public override void Simulate( Client cl )
{
if ( Input.VR.RightHand.ButtonA.IsPressed )
{
// Do something when the A button on the
}
}
```
## Finger Tracking
<upload src="a5727/8dabe5aa5cb45d7.mp4" size="22604970" name="vrfingertracking(1).mp4" />
You can get the finger curl and splay, which allows you to pose the fingers to match your real life fingers in game.
```csharp
var curl = Input.VR.LeftHand.GetFingerValue( FingerValue.ThumbCurl );
var splay = Input.VR.LeftHand.GetFingerValue( FingerValue.ThumbIndexSplay );
curl = Input.VR.LeftHand.GetFingerCurl( 0 ); // 0 - 4
splay = Input.VR.LeftHand.GetFingerSplay( 0 ); // 0 - 3
```

## Head
Head mounted device position and rotation can also be accessed simply through Input.VR.Head.
## Trackers
<upload src="a5727/8dabdcb19fdb1ab.mp4" size="3405378" name="vrtrackers.mp4" />
You can get the position and rotation of any [puck trackers](https://www.vive.com/us/accessory/tracker3/), and also your base stations if you're not using a quest.
```csharp
foreach( var trackedObject in Input.VR.TrackedObjects )
{
DebugOverlay.Axis( trackedObject.Transform.Position, trackedObject.Transform.Rotation );
}
```
# Haptics
<note>These are clientside only currently</note>
Haptic vibrations can be triggered per hand using Input.VrHand.TriggerHapticVibration you can call this as often as you like, if a haptic event is already running it will be interrupted immediately.
```csharp
// Pulse right hand haptics with an amplitude scaled from velocity
Input.VR.RightHand.TriggerHapticVibration( 0f, 200.0f, Math.Clamp( 0.4f + Velocity.Length / 500f, 0.4f, 0.8f ) );
```
Something to consider is different controllers have different limitations to their haptics, something I've noticed with Oculus controllers is the frequency is a lot less responsive than other controllers for example.
