How to rotate and scale an object?

To rotate and scale an object, first ensure that the Manipulation Handler (Script) and Near Interaction Grabbable (Script) components are added to the object. The Manipulation Handler (Script) allows you to manipulate an object while the Near Interaction Grabble (Script) allows the object to respond to near hand interactions.

To add the scripts to the object, first select the object in the Hierarchy window. In the Inspector window, click Add Component and search for each script. Once found, select the script to add to the object.

With the object selected, in the Inspector window, navigate to the Manipulation Handler (Script) component to modify the component's parameters.

You can rotate an object using one or two hands. This setting is dependent on the Manipulation Type parameter. The Manipulation Type can be limited to either:

  • One Handed Only

  • Two Handed Only

  • One and Two Handed

Select Two Handed Only for Manipulation Type so that the user can only manipulate the object with two hands.

To limit the two handed manipulation to rotating and scaling, change Two Handed Manipulation Type to Rotate Scale.

To limit whether the object can be rotated on the x, y or z axis, change Constraint on Rotation to your preferred axis.

You can now test rotating and scaling the object using the in-editor simulation. Press the Play button to enter Game mode. Once in Game mode, press T and Y on the keyboard to toggle both hands. This will permanently display both hands in Game mode. Press the space bar to move the right hand and use left mouse click + Shift to move the left hand. While either controlling the left or right hand, use the mouse to rotate and scale the object.
