Stop an Object if it reached the transform value
So I have a 2d gameObject that behaves likes a spike trap that springs out of the ground when the character collides on the trigger. I use AddForce to the rigidbody 2D of the gameObject to manipulates its speed when coming out of the ground and I want it to just sticking out of the ground. How can I stop it when it reaches a certain tranform Y value.
Here is my code:
public float speed;
Rigidbody2D rb;
void Start () {
rb = GetComponent<Rigidbody2D>();
}
void Update () {
}
private void OnTriggerEnter2D(Collider2D collision)
{
if (collision.gameObject.tag == "Player")
{
rb.AddForce(new Vector2(0, speed * Time.time), ForceMode2D.Impulse);
}
}

try 'rb.AddForce(transform.up * speed, ForceMode.Impulse);'

you can check position y in Update()

Certain transform value, or certain transform.position value?
I'll do it like this:
private float threshold = 10f;
private float startPosition = 0;
private RigidBody2D pikeRigidbody;:
private void Start()
{
startPosition = = this.transform.position;
pikeRigidbody = this.GetComponent<RigidBody2D>();
}
private void Update(){
if(this.transform.position.y >= (startPosition.y + threshold))
{
pikeRigidbody.velocity = Vector3.zero;
}
}
And attach the script to the pike object.
Edited to position.y instead of position
