Rigidbody.position

Description

Позиция твердого тела.

Rigidbody.position allows you to get and set the position of a Rigidbody using the physics engine. If you change the position of a Rigibody using Rigidbody.position, the transform will be updated after the next physics simulation step. This is faster than updating the position using Transform.position, as the latter will cause all attached Colliders to recalculate their positions relative to the Rigidbody.

Если вы хотите двигать твердое или кинематическое тело непрерывно, используйте вместо него MovePosition или MoveRotation.
