As a general rule, the Player is subject to gravity. This is a parameter that allows the player to use the physical properties of gravity, such as jumping (default is Space) or falling if the floor disappears from under the player's feet. If gravity is turned off, however, these rules will not apply. You can disable gravity in the logic editor

The action radius of the player's hands is equal to the pointer beam on the controller - this is the beam coming from the controller that the user sees in VR mode, helping the user to better "aim" at objects in the scene in the running project. The beam can be customized based on your needs

More information about the parameters can be found in the documentation

The object is inside another object/location or intersects with it, at which point we cannot let it go from our hand. It is necessary to first pull the object out of the obstacle, and then the red illumination will disappear
