Object colliding with nothing.

I am making a stickman parkour/plat former type game. I want my player to be able to throw objects. However, when I throw the object it sometimes gets stuck in mid air. It behaves like there is a collider below it, however there is none. I set the RigidBody2D colliion detection to continous. No other object is under it. Here is a picture:

Here are the settings on the box/crate in the photo:


Any ideas?

 

Do you have your elements separated by layer correctly? That would be my first guess.

 

Yes they are. Why is that a problem?

 

What is the code you are using for throwing the box?

 

Here is the code:

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class HoldObjectScript : MonoBehaviour
7. {
8.     // Arm that will hold object
9.     public Rigidbody2D arm;
10.  
11.     // Player root object
12.     public GameObject root;
13.  
14.     // Point where to connect the object
15.     public Transform connectPoint;
16.  
17.     // Joint used to connect objects
18.     private HingeJoint2D currentJoint;
19.  
20.     // Settings
21.     public float throwStrength;
22.  
23.     public void TryHoldObject(GameObject obj)
24.     {
25.         if (Input.GetKeyDown(KeyCode.H))
26.         {
27.             // We get the joint that will be used to connect the object
28.             HingeJoint2D joint = obj.GetComponent<HingeJoint2D>();
29.  
30.             // We connect the object to arm
31.             joint.connectedBody = arm;
32.  
33.             joint.connectedAnchor = connectPoint.localPosition;
34.  
35.             // We disable all collisions between object and player
36.             DisableCollisions(obj.GetComponent<Collider2D>());
37.  
38.             // Enable the joint
39.             joint.enabled = true;
40.            
41.             // Remember the joint
42.             currentJoint = joint;
43.         }
44.     }
45.  
46.     public void StopHolding()
47.     {
48.         EnableCollisions();
49.         currentJoint.enabled = false;
50.     }
51.  
52.     void DisableCollisions(Collider2D collider)
53.     {
54.         Collider2D[] colliders = root.GetComponentsInChildren<Collider2D>();
55.  
56.         for (int i = 0; i < colliders.Length; i++)
57.         {
58.             Physics2D.IgnoreCollision(colliders[i], collider);
59.         }
60.     }
61.  
62.     void EnableCollisions()
63.     {
64.         Collider2D[] colliders = root.GetComponentsInChildren<Collider2D>();
65.         Collider2D collider = currentJoint.GetComponentInParent<Collider2D>();
66.  
67.         for (int i = 0; i < colliders.Length; i++)
68.         {
69.             Physics2D.IgnoreCollision(colliders[i], collider, false);
70.         }
71.     }
72.  
73.     public void ThrowObject(Vector2 direction)
74.     {
75.         Rigidbody2D objectRb = currentJoint.GetComponentInParent<Rigidbody2D>();
76.  
77.         StopHolding();
78.  
79.         objectRb.velocity = direction * throwStrength;
80.     }
81. }
82.  

I basically receive a direction and apply a force to it.
