Unity stepping on the pit record - the use of GetComponent

1. The first problemis to print the relativePosition and relativeRotation of the object relative to the main camera.

There has been a problem with the result. Through the frame test, it is found that the correct value has not been found, and the problem is not found until after the step-by-step printing and debugging: GetComponent has always obtained a part of the component of the object instead of all components.

The print result is as follows: The part of the yellow frame is printed, not the entire machine.
