Unity 2d Freezing Player in Position on Collision

I’m currently making a 2d platformer and I need one of my enemies to freeze the player in it’s current position when it collides with the player. I want the player to be unable to move but still able to shoot his gun.

void OnTriggerEnter2D(Collider2D other){
if(other.gameObject.tag == "Player"){

transform.position = target.position;
		 
transform.LookAt(new Vector3 (20, 0, 0));

//code to freeze player in place until enemy dies from player gunfire
   }
}

if you want to freeze the player, just set its velocity and gravity to 0. Before, you need to add rigidbody2D to the player…

function OnCollisionEnter2D(coll:Collision2D)
{
	rigidbody2D.velocity.x=0;
	rigidbody2D.velocity.y=0;
	rigidbody2D.gravityScale=0.0;
        
       //Do other stuffs

}

I guess you want collision, so i used OnCollisionEnter2D()…

when using OnTriggerEnter2D make sure the gameobject Boxcollider2D property isTrigger is checked?

For the positions:

rigid.constraints = RigidbodyConstraints2D.FreezePositionX | RigidbodyConstraints2D.FreezePositionY;

For rotation:

Rigidbody2D.constraints = RigidbodyConstraints2D.FreezeRotationZ;

For both:

rigid.constraints = RigidbodyConstraints2D.FreezePositionX | RigidbodyConstraints2D.FreezePositionY | RigidbodyConstraints2D.FreezeRotationZ;

PS. code is not tested.

You could simply do RigidBody2D.velocity = 0;
