2D Ball physics?

My apologies for the vague title.

I'm working on a concept with very little C#/programming knowledge. I'm looking to have a 2D Ball that move indefinitely unless certain triggers are met. It bounces off of objects to gain speed and "rolling" affects it's curvature when traveling between contact points.

I've got the ball moving, I've got the ball bouncing. My current issue is the ball always slows to a stop completely regardless of my current settings and if I change anything by a decimal of a fraction the results go wildly out of control (IE: the ball is too bouncy, it goes between walls, speeds up with no stop, and eventually breaks the collision boxes and flies out of the world boundaries. Funny to watch, not good for my game mechanic).

I suppose the simplest way to solve this problem would be to set a minimum speed so it doesn't slow down and possibly a maximum speed to the player object itself but I am unaware of how to achieve this via C# (I'm sure this is simple I just lack the experience...)

I have a few other "problems" that have me stumped but I cannot explain these without screenshots of sorts and am away from my build at the moment.

Any help is very much appreciated!

 

ok you store the rigidbody

Code (CSharp):

1. Rigidbody2D rbody = gameObject.GetComponent<Rigidbody2D>()
2.  
3. if(rbody.velocity > maxVelocity)
4. rbody.velocity = rbody.velocity.normalized* maxVelocity;
5.  
6. //same for min velocity
7.  
8.  
9. if(rbody.velocity < minVelocity)
10. rbody.velocity = rbody.velocity.normalized* minVelocity;

 

Try setting rigidbody drag to zero
