ECBehaviorVRHand

Behavior in action

Behavior element behavior adding VR Hand Controller support to actor. This behavior tracks one hand controller optionally displaying it on screen using either the developer provided model or a custom model. Optionally a rig can be assigned to get physical presence of the controller in the game world.

Instance Counts

This behavior can be added twice to an element to add support for left and right hand controller. Use the behavior identifier to tell them apart.

Element Class Properties

Element class properties have the prefix vrHand. or vrHand(id). if id is not empty.

useVendorModel

Determines if the Vendor Specific 3D Model is used to show the device. The Vendor Specific 3D Model is provided by the VR Runtime installation. If set to false vrHand(id).component.* properties can be used to define the model to use.

showHand

Determines if the device is shown in the 3D view. Set this to true if you use a separate model to show the hands. Set to false if you use the regular animated actor support to animate the hands using the hand position and orientation as input.

component.*

This behavior adds a child ECBehaviorComponent to the element class to show the hand in the game world. The child behavior has the identifier “vrHand” or “vrHand(id)”. The child behavior has the element class property prefix “vrHand.component.” or “vrHand(id).component.”.

Hence to set for example the component model of the right hand use the element class property “vrHand(right).component.model”

Required Behaviors

Optional Behaviors

Use Cases

Element Class Example

The following example creates an element class with two hand controllers.

class MyElement extends BehaviorElementClass
  public func new()
    // Add VR Playspace behavior. Base behavior required by all VR behaviors
    var ECBehaviorVRPlayspace vrPlayspace = ECBehaviorVRPlayspace.new(this)
    
    // Add VR HMD behavior. With this behavior present VRPlayerControlledActorCameraDirector
    // can attach the HMD to the in-game camera
    ECBehaviorVRHMD.new(this, vrPlayspace)
    
    // Add left and right hand controller. The InputDeviceType is required
    // for the behavior to know which input device to monitor
    ECBehaviorVRHand.new(this, vrPlayspace, InputDeviceType.vrRightHand, "right")
    ECBehaviorVRHand.new(this, vrPlayspace, InputDeviceType.vrLeftHand, "left")
  end
end
