Items can be moved when they are displayed semi-transparently. The location selected by the reticle in the center of the screen is where the item will be placed.
In the mobile and desktop versions, the reticle is always centered and can be moved by moving the avatar's perspective.
In order to make the reticle visible, the avatar's view is slightly shifted to the left when viewed from the third-person perspective in craft mode.
In the VR version, items can be moved by operating the controller.
