The world space position of the Transform.

The position property of a GameObject’s Transform, which is accessible in the Unity Editor and through scripts. Alter this value to move a GameObject. Get this value to locate the GameObject in 3D world space.

The following example updates the position of a sphere. It bounces up and down and rotates in a circle.
