Description

VR Grab Component is a scene component for grabbing/interacting(See VR Hand).



Settings


Can Put In Inventory - This variable indicates if player can put an actor to the hand inventory.  Grab Method -  This variable indicates the grab method(See VR Variables). Each selection will bring additional parametrs such as animation variables, sockets etc.(In PhysicsAnimated and PhysicsAnimatedNearSocket, animation array index equals socket array index)  Allow Pick Up - This variable indicates if a player can grab the component.  Allow Drop - This variable indicates if a player can drop the component.  Both Hands -  This variable indicates if player can the actor with both hands.  Can Player Step On - This variable indicates if player can step on this actor.  Can NPC Interact - This variable indicates if NPC can interact with this actor.  Max Component Interaction Distance - This is the max distance within which hand can grab.  Enable Priority - This prioritizes current grab component to be grabbed first among others.  Auto Hand Rotation - If set to true hand will be automatically rotated to fit the position.  Weld with hand - If true the component will be welded with a hand on grab.  Lower Attached Strength - If true physics constrraint force will be lower.  Can Pull Grab - This variable indicates if a player can pull grab this actor.
VR Grab Component Settings

  • Can Put In Inventory - This variable indicates if player can put an actor to the hand inventory.

  • Grab Method - This variable indicates the grab method(See VR Variables). Each selection will bring additional parametrs such as animation variables, sockets etc.(In PhysicsAnimated and PhysicsAnimatedNearSocket, animation array index equals socket array index)

  • Allow Pick Up - This variable indicates if a player can grab the component.

  • Allow Drop - This variable indicates if a player can drop the component.

  • Both Hands - This variable indicates if player can the actor with both hands.

  • Can Player Step On - This variable indicates if player can step on this actor.

  • Can NPC Interact - This variable indicates if NPC can interact with this actor.

  • Max Component Interaction Distance - This is the max distance within which hand can grab.

  • Enable Priority - This prioritizes current grab component to be grabbed first among others.

  • Auto Hand Rotation - If set to true hand will be automatically rotated to fit the position.

  • Weld with hand - If true the component will be welded with a hand on grab.

  • Lower Attached Strength - If true physics constrraint force will be lower.

  • Can Pull Grab - This variable indicates if a player can pull grab this actor.

  • Grab Animation - This is hand grab animation variable which applyies on grab.

  • Trigger Animation - This is hand trigger press animation variable which applyies on trigger press.

  • A Pressed Animation - This is hand A press animation variable which applyies on A press.

  • B Pressed Animation - This is hand B press animation variable which applyies on B press.

  • Check For Child Collisions Axis - Checks if child collisions of UVR_GrabBoxCollisionComponent and UVR_GrabCapsuleCollisionComponent are attached to the component. If there are child collisions hand will be snapped to the nearest one.
