OnCollisionStay and keeping a RigidBody awake

Hello all,

New to Unity and mostly new to C# with some previous programming experience. I am playing around with Unity and experimenting around with adding my own additional physics. An issue I am running into is I have noticed that `OnCollisionStay` stops firing after a certain amount of time has passed where they are no longer moving.

I consider my code to be physics-based and I am exchanging information through the two object when they collide and I am using `Time.deltaTime` to moderate the speed of that data transfer.

The problem is, after the Rigidbody freezes due to not moving, my calculations in `OnCollisionStay` get corrupted because the value of `Time.deltaTime` becomes `infinity`.

So currently it seems there is some kind of loop in the Rigidbody component that looks to see if there is a minimum amount of "force" being applied before automatically falling asleep.

Is there some kind of pseudo force I can apply until I am ready for the object to fall asleep?

Shame the RigidBody code isnt accessible/editable.

 

Ok I'm still looking into it but the rest may be an error in my unrelated functions perhaps. I believe this is working.

Code (CSharp):

1.  void OnCollisionStay(Collision collisionInfo)
2.     {
3.         float dataTransferRate = someDataAmount * Time.deltaTime;
4.         Debug.Log("dataTransferRate (per frame): " + dataTransferRate);
5.         AddEnergy(dataTransferRate);
6.        
7.         if (bool)
8.         {
9.             rb.sleepThreshold = 0f;
10.         } else
11.         {
12.             rb.sleepThreshold = 0.005f;
13.         }
14.     }
