Collision not detected

Hi all,
in a 2d Project the collision evet is not getting fired.

i have a missile gameObject with rigidbody (not kinematic) and 2d box collider

then i have a second gameObject, with rigidbody (kinematic) and a 2d box collider

if i try the collision, i can see the missile, stopping nearby the collider (cause the target is kinematic) if i check the trigger in the target, the missile get through, but the OnTriggerEnter event is not getting fired. The OnTriggerEvent is located in a script in the target gameObject

void OnTriggerEnter(Collider other) {

	Debug.Log ("Collide");

	if (other.tag == "Laser") { 
		Debug.Log("Hit by a Laser");


what am i doing wrong?

I can tell you only some alternatives such as OnTriggerEnter(Collider other) should be OnTriggerEnter2D(Collision2D other) { }
Or instead of
if (other.tag == “Laser”) { }
I’d use
if (other.gameObject.CompareTag(“Laser”)) { }

I know it’s a common thing but i’m a learner so sorry if it doesn’t work

Yes it needs to be OnTriggerEnter2D and use Compare instead of ==, also I think other.tag should be other.gameObject.tag. The other thing to check is to make sure your objects are all tagged correctly. You can put a debug.log(other.gameObject.tag) to check to see the tags that are colliding.

Appreciate your answers guys but the question is from 2014!
