Changing the placement of circular motion in 2D?

Questions & Answers

Hello :smiley:

I’ve just started in unity a couple weeks back. I am attempting to make a certain circular motion happen when it’s in a certain position. However because of the codes i used to create the circular motion, it goes back to the default position of 0, 0 for x and y.

float timeCounter=0;

float speed;
float width;
float height;

void Start () {
	speed = 2;
	width = 0.3f;
	height = 0.3f;
}

void Update () {
	timeCounter += Time.deltaTime * speed;

	float x = Mathf.Cos (timeCounter) * width;
	float y = Mathf.Sin (timeCounter) * height;

	transform.position = new Vector2 (x, y);
}

how do i place the circular motion in another position than 0, 0?

Hi. Try to use “%gameObject.transform.position” instead of “transform.position”.

#pragma warning disable 649
        [SerializeField]
        private GameObject _targetGameObject;

        [SerializeField]
        private Vector2 _offSetPosition = Vector2.zero;
#pragma warning restore 649

        float _timeCounter;
        float _speed;
        float _width;
        float _height;

        private void Start()
        {
            _speed = 2;
            _width = 0.3f;
            _height = 0.3f;
        }

        private void Update()
        {
            _timeCounter += Time.deltaTime * _speed;
            float x = Mathf.Cos(_timeCounter) * _width;
            float y = Mathf.Sin(_timeCounter) * _height;
            _targetGameObject.transform.position = new Vector2(x, y) + _offSetPosition;
        }
