Bouncing Bullets Not Working

Hello!

I am trying to make bullets ricochet off of metal objects, but not off of anything else. Right now it collides with everything fine, but after hours of looking at tutorials, this feature still will not work. The bullets simply travel through anything that is metal.

A few things to mention: the bullets are using the trigger collider, because if they didn't they interact with the rigidbody on the tank. If you can think of a way for the bullets to NOT interact with the tank, but still use the 'OnCollisionEnter' method, I am open to this as a solution as well. Second, the environment the bullet is interacting with is in the collisionMask var on line 17, so that is not the issue. Third, when debugging, the only thing that is printed is "Hit metal" from line 15.

Here is my code:

Code (CSharp):

1. private void OnTriggerEnter2D(Collider2D collision)
2.     {
3.         try
4.         {
5.             if (collision.gameObject.GetComponent<Actor>() != cameFrom)
6.             {
7.                 collision.gameObject.GetComponent<DamageHandler>().TakeDamage(damage);
8.                 if (!collision.gameObject.GetComponent<DamageHandler>().IsMetal())
9.                 {
10.                     Destroy();
11.                 }
12.                 else
13.                 {
14.  
15.                     Debug.Log("Hit metal");
16.                     Ray ray = new Ray(transform.position, transform.forward);
17.                     if(Physics.Raycast(ray, out RaycastHit hit, Time.deltaTime * bulletSpeed +0.1f, collisionMask))
18.                     {
19.                         Debug.Log("Before Reflection: " + transform.eulerAngles);
20.                         Vector2 reflectDir = Vector2.Reflect(ray.direction, hit.normal);
21.                         float rot = 270 - Mathf.Atan2(reflectDir.y, reflectDir.x) * Mathf.Rad2Deg;
22.                         transform.eulerAngles = new Vector3(0, 0, rot);
23.                         Debug.Log("After Reflection: " + transform.eulerAngles);
24.                     }
25.                 }
26.  
27.             }
28.         }
29.        
30.     }

Thanks for your help!

 

Ok, thank you! I am new to the unity forums and still trying to find my way around. I will look into physics2D and post in that forum if I still need help.
