Collision Knocks me sideways?

So, we’re writing a basic snake game and having the issue where when we collide with the box it makes us start slowly rotating, sadly the OnCollisionEnter won’t work unless there is a physical collision. Here is the script so you can help me out.

I need to find a way to make it so it doesn’t move me when I collide with it, like… Make a stationary collision as terrain does. When you hit it, it doesn’t make you “Bounce”

I need to remove the “Bounce” in the collision.

It’s a sphere and a cube, sphere has sphere collider and rigidbody, cube has cube collider and rigidbody, without these the script doesn’t do anything when I touch the object.

Movement.cs

using UnityEngine;
using System.Collections;

public class Movement : MonoBehaviour 
{

	public float speed;
	public float rotateSpeed;

	public Transform myTransform;
		
	
	void Start ()
	{
		speed = 5.0f;
		rotateSpeed = 5.0f;
		myTransform = transform;
		
	}	
	
	void Update ()
	{
		if(Input.GetKey(KeyCode.W))
	    myTransform.position += myTransform.forward * speed * Time.deltaTime;
		if(Input.GetKeyUp(KeyCode.A))
		{
			transform.Rotate(0,-90,0);
			
		}
	
		if(Input.GetKeyUp(KeyCode.D))
		{
			transform.Rotate(0,90,0);
			
		}
	}
}

Collision.cs

using UnityEngine;
using System.Collections;

public class CollisionHandler : MonoBehaviour {

	HealthHandler healthHandler;
	
	void Start() {
		healthHandler = GetComponent<HealthHandler>();
	}
	
    void OnCollisionEnter(Collision collision) {
     if(collision.gameObject.tag == "Enemy") {
			Destroy (collision.gameObject);
			healthHandler.currentHealth -= 10;
			Debug.Log ("Hit Enemy");
   	 	}
	}
}

May I suggest using isTrigger. Like OnTriggerEnter. I assume some basic snake game where the objects are square. So say your eatable item is a box collider and set is trigger to true. Allowing the physics engine not to be called then using the OnTrigger event functions which act similar to OnCollision without calling Physx.

In simple terms, there is an invisible box. If you collide with it, but in this terms “trigger” it then the following functions are called by Unity OnTriggerEnter, OnTriggerExit and OnTriggerStay.
