Transforms position
from world space to local space. The opposite of Transform.TransformPoint.
Note that the returned position is affected by scale. Use Transform.InverseTransformDirection if you are dealing with directions.

Transforms the position x

, z
from world space to local space. The opposite of Transform.TransformPoint.
Note that the returned position is affected by scale. Use Transform.InverseTransformDirection if you are dealing with directions.
