I want to set the starting position before running the game in the editor when I drag the transform to some position when running the game it's changing back to the originPosition if I mark not to use the line at the Start()

//originPosition = transform.position;

Than it will start from the other side at all. I want it to start moving from where I set it at the start position.

Moving the line

originPosition = transform.position;

To the Update() is also not a solution.

CodePudding user response：

If transform.position returns something different from what you’ve set in edit mode, it’s affected by something else on Start() or Awake() in some script. Also it is possible, that some script sets public go variable to true on awake.
