Manage manipulable items pick and leave

Manage pick and leave Items

This section outlines an approach to implement Manipulable items pick and leave.

• Picking means being able to assign an item to the manipulator and eventually taking it from an attach point.

• Leaving means being able to remove an item from the manipulator and eventually assigning to an attach point.

Topics

• Using a selection tool item

• Picking and leaving items

Manipulation commands

The manipulation system provides two commands, start_manipulator and stop_manipulator to simplify manipulator pick and leave.

start_manipulator

Activates the manipulation system by setting the InteractionSelectorselectionMode to Manipulator.

Alternatively, it requires these passed arguments:

• The name of an item that has a Manipulable referring to it. This item becomes the manipulatedNode.

• The name of two items with Manipulables associated to them. The first is the manipulatedNode. The second is assigned to the secondary controller (left by default).

stop_manipulator

Leaves the manipulated node where it is and disables manipulation mode for InteractionSelector.

This command is rarely used due to the following reasons:

• Usually, a manipulated node needs to be left attached to an AttachPoint .

• Leaving a manipulator without a manipulated node prevents the collision system from working.
