BoxCollider2D collisions not working for some reason

I have two objects. One is spawned with a bouncy physics material, and it's velocity is set towards the other object. They should collide, one should bounce off. However they are just passing through each other most of the time.

-I've set both rigidbodies to continuous collision.
-I've set a script that prints "collided" when the two collide, so it's saying they are colliding.
-However nothing is happening.

Sometimes they will collide, sloppily, but mostly they just pass through and collide with the polygon collider behind the other object.

Here is a picture example



Here is the script for thing that fires the smaller square

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class BasicEnemy : MonoBehaviour
5. {
6.     public GameObject bullet;
7.     public float bulletSpeed = 20;
8.  
9.     bool inFireArea = false;
10.     bool fireTime = true;
11.     GameObject player;
12.  
13.     void Awake()
14.     {
15.         player = GameObject.FindGameObjectWithTag ("Player");
16.     }
17.  
18.     void Update()
19.     {
20.         CheckFireArea();
21.         if(inFireArea == true && fireTime == true)
22.         {
23.             fireTime = false;
24.             Fire ();
25.         }
26.         LookAtPlayer ();
27.     }
28.  
29.     void LookAtPlayer()
30.     {
31.         Vector3 dir = player.transform.position - transform.position;
32.         float angle = Mathf.Atan2(dir.y,dir.x) * Mathf.Rad2Deg;
33.         transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);
34.     }
35.  
36.     void CheckFireArea()
37.     {
38.         Vector2 playerPos = player.transform.position;
39.         Vector2 pos = transform.position;
40.         float distance = pos.x - playerPos.x;
41.         if(distance < 40 && distance >= -1)
42.         {
43.             inFireArea = true;
44.         }
45.         else
46.         {
47.             inFireArea = false;
48.         }
49.     }
50.  
51.     void Fire()
52.     {
53.         GameObject bulletZone = this.transform.Find ("FireFrom").gameObject;
54.         Vector3 facing = this.transform.right;
55.         facing.x = facing.x + .6f;
56.         GameObject bulletInstance = Instantiate (bullet, bulletZone.transform.position, Quaternion.identity) as GameObject;
57.         Rigidbody2D rb = bulletInstance.GetComponent<Rigidbody2D>();
58.         rb.velocity = facing * bulletSpeed;
59.         StartCoroutine ("ResetFireTime");
60.     }
61.  
62.     IEnumerator ResetFireTime()
63.     {
64.         yield return new WaitForSeconds(.7f);
65.         fireTime = true;
66.     }
67. }

Here is the script for the rectangle it is supposed to collide with

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Shield : MonoBehaviour
5. {
6.     GameObject shieldBase;
7.     Transform rotation;
8.     Vector2 shieldPos;
9.     void Awake()
10.     {
11.         shieldBase = GameObject.FindGameObjectWithTag ("Follow");
12.     }
13.     void Update()
14.     {
15.         ShieldMovement ();
16.     }
17.  
18.     void ShieldMovement()
19.     {
20.         rotation = shieldBase.transform;
21.         shieldPos = shieldBase.transform.position;
22.         transform.rotation = rotation.rotation;
23.         transform.position = shieldPos;
24.     }
25.  
26. }

There should be no conflicts between either script. So i don't see why the objects wouldn't collide.
What's really weird is i've literally done this prototype before with no collision issues. I don't understand why it wouldn't be working now.

 

is "Is Trigger" checked?
it should not be.

 

It isn't. I think the problem might be that the larger block is using transform.position to move. But i don't see how I can make it follow the capsule without parenting it or using transform.position.

 

Thank you for awaring me on rigidbody2d.moveposition. However, it seems to be an incredibly stuttery command. I have it in update, and i'm telling it to move its position to mimic the position of another object every frame. And it seems to have a hard time doing that in any smooth way.
It is moving along the vector2 i've commanded, but shaking violently.

Ex script:

Code (CSharp):

1. public class Shield : MonoBehaviour
2. {
3.     GameObject shieldBase;
4.     Transform rotation;
5.     Vector2 shieldPos;
6.     Rigidbody2D rb;
7.     void Awake()
8.     {
9.         shieldBase = GameObject.FindGameObjectWithTag ("Follow");
10.         rb = GetComponent<Rigidbody2D>();
11.     }
12.     void Update()
13.     {
14.         ShieldMovement ();
15.     }
16.  
17.     void ShieldMovement()
18.     {
19.         rotation = shieldBase.transform;
20.         shieldPos = shieldBase.transform.position;
21.         transform.rotation = rotation.rotation;
22.         rb.MovePosition (shieldPos);
23.     }
24.  
25. }
