ForceMode.Impulse object movement stops when key is released

Hello, I just made this simple script which makes my gameObject moves in diagonal directions. D key for right/up movement and A key for left/up movement. I want the movement to continues until gravity stops it and gameObject starts to falling to the ground. This happens just fine with Y force, the gameObject keep ascending til gravity makes its job but for unknow reason X force just instant stops once key is released.

Code (CSharp):

1.  
2.     private float _forceX = 10f;
3.     private float _forceY = 5f;
4.  
5.     void FixedUpdate()
6.     {
7.         KeyboardController();
8.     }
9.  
10.     void KeyboardController()
11.     {
12.         var _rb = GetComponent<Rigidbody>();
13.  
14.         if (Input.GetKey(KeyCode.D))
15.         {
16.             _jetpackParticle.Play(); // Parcticle system
17.             _rb.AddForce(new Vector3(_forceX, _forceY, 0), ForceMode.Impulse);
18.             _anim.SetBool("isMirrorFlying", false); // Animator
19.  
20.         }
21.         else if (Input.GetKey(KeyCode.A))
22.         {
23.             _jetpackParticle.Play(); // Parcticle system
24.             _rb.AddForce(new Vector3(_forceX * -1, _forceY, 0), ForceMode.Impulse);
25.             _anim.SetBool("isMirrorFlying", true); // Animator
26.         }
27.         else
28.         {
29.             _jetpackParticle.Stop(); // Parcticle system
30.         }
31.     }

Also, when checking the info section on the rigidbody component I can see how speed on Y is increased while speed on X keeps at zero even when the gameObject is moving on X axis on the playmode screen.


Thanks!

 

Ok, the problem always was the animator in my object. It seems animations touch rigidbody somehow.

What I did is put my original object inside a new empty object then delete the rigidbody component from my original object and create a new one in the parent object.
